Oracle 12C 跨网络传输数据库

Posted on 2017年6月2日2017年6月2日 by YongJing(敬勇)

跨网络传输数据库，可以通过使用network_link参数来执行导入操作，导入操作将使用数据库链路，不需要生成dump文件。操作步骤如下:
1.在目标数据库中创建链接到源数据库的数据链路。执行导入操作的用户必须要有datapump_imp_full_database权限，并且连接到源数据库的数据链路也必须连接到一个有datapump_exp_full_database角色的用户。在源数据库中用户不能有sysdba管理权限。

2.在源数据库上将所有用户表空间置为只读模式

3.将源数据库中所有用户表空间相关的数据文件传输到目标数据库。如果源平台与目标平台的字节编码不同，那么查询v$transportable_platform视图来进行查看。并且将可以使用以下一种方法来转换数据文件：
.使用dbms_file_transfer包中的get_file或put_file过程来传输数据文件。这些过程会自动将数据文件的字节编码转换为目标平台的字节编码。

.使用rman的convert命令来将数据文件的字节编码转换为目标平台的字节编码。

4.在目标数据库上执行导入操作。使用Data Pump工具来导入所有用户表空间的元数据与管理表空间的元数据与真实数据。确保以下参数正确设置:
.transportable=always
.transport_datafiles=list_of_datafiles
.full=y
.network_link=database_link
.version=12
如果源数据库为11.2.0.3或11g之后的版本，那么必须设置version=12。如果源数据库与目标数据库都是12c，那么version参数不用设置。

如果源数据库包含任何加密表空间或表空间包含加密列，那么你必须指定encryption_pwd_prompt=yes或指定encryption_password参数。

Data Pump跨网络导入将会复制所有用户表空间所存储对象的元数据与管理表空间中的元与用户对象的真实数据。当导入完成后，用户表空间将会置于读写模式。

5.可选操作将源数据库中的所有用户表空间置为读写模式。

下面的例子是将源数据库jyrac传输到目标数据库jypdb
1.在目标数据库中以sys用户来创建链接到源数据库的数据链路。源数据库中的用户为jy

SQL> conn sys/xxzx7817600@jypdb as sysdba
Connected.


SQL> create public database link jyrac_link
  2    connect to jy identified by "jy"
  3    using '(DESCRIPTION =
  4      (ADDRESS_LIST =
  5        (ADDRESS = (PROTOCOL = TCP)(HOST =10.138.130.153)(PORT = 1521))
  6      )
  7      (CONNECT_DATA =
  8        (SERVER = DEDICATED)
  9        (SERVICE_NAME =jyrac)
 10      )
 11    )';

Database link created.

2.在源数据库上将所有用户表空间置为只读模式

SQL>  select tablespace_name,status from dba_tablespaces;

TABLESPACE_NAME                STATUS
------------------------------ ---------
SYSTEM                         ONLINE
SYSAUX                         ONLINE
UNDOTBS1                       ONLINE
TEMP                           ONLINE
USERS                          ONLINE
UNDOTBS2                       ONLINE
EXAMPLE                        ONLINE
TEST                           ONLINE

8 rows selected.

SQL> alter tablespace test read only;

Tablespace altered.

SQL> alter tablespace users read only;

Tablespace altered.

SQL> alter tablespace example read only;

Tablespace altered.

SQL> select tablespace_name,status from dba_tablespaces;

TABLESPACE_NAME                STATUS
------------------------------ ---------
SYSTEM                         ONLINE
SYSAUX                         ONLINE
UNDOTBS1                       ONLINE
TEMP                           ONLINE
USERS                          READ ONLY
UNDOTBS2                       ONLINE
EXAMPLE                        READ ONLY
TEST                           READ ONLY

8 rows selected.

3.在目标数据库中使用dbms_file_transfer包中的get_file过程将源数据库中所有用户表空间相关的数据文件传输到目标数据库上
在源数据库中创建目录tts_datafile（存储数据文件)

SQL> create or replace directory tts_datafile as '+datadg/jyrac/datafile/';

Directory created.

SQL> grant execute,read,write on directory tts_datafile to public;

Grant succeeded.

重命名与迁移联机数据文件

Posted on 2017年5月31日 by YongJing(敬勇)

重命名与迁移联机数据文件
在12C中可以使用alter database move datafile语句来重命名或迁移联机数据文件。当数据库处于open状态，并且用户正在访问数据文件时仍然能够重命名与迁移联机数据文件。

当你重命名与迁移联机数据文件时，在控制文件中所记录指向数据文件的指针会被改变。数据文件会在操作系统层面被重命名与迁移。

当执行以下任务时因为需要允许用户访问数据文件所以需要对联机数据文件执行重命名与迁移:
.将数据文件从一种类型的存储迁移到另一种类型存储上。
.将不频繁访问的数据文件迁移到低成本存储上。
.将表空间置为只读并将它的数据文件写入存储设备上
.将数据库迁移到Oracle ASM中

当执行alter database move datafile语句时，如果在目标目录中存在相同的文件，可以指定reuse选项来覆盖现有文件。当没有指定reuse选项时，如果在目标目录中存在相同文件时，现有文件不会被覆盖并且语句会返回错误信息。

缺省情况下，当执行alter database move datafile语句并指定新目录时，语句会移动数据文件到新目录中。然而可以指定keep选项来保留旧目录中的数据文件。在这种情况下当语句完成后数据库只会使用新目录中的数据文件。

使用alter database move datafile语句来重命名或迁移数据文件时，Oracle数据库会创建一份数据文件副本。确保对于有足够的空间来执行此操作。

注意:如果指定的数据文件处于脱机状态那么执行alter database move datafile语句将会触发错误,如果配置了备库，那么对于主库和备库所执行的联机数据文件迁移操作是相互独立的。当对主库移动数据文件时备库不受影响，反之一样。闪回操作不会将被移动的数据文件重新迁移回之前的目录中。如果将一个联机数据文件从一个目录移动到另一个目录，之后执行闪回数据库操作将其闪回到数据文件迁移之前的时间点，那么数据文件仍然会存储在新目录中，但数据文件的内容将会回到闪回操作所指定的时间点。当在Windows平台上执行数据文件迁移时，就算没有指定keep选项，原始数据文件也会保留在旧目录中。在这种情况下，当迁移操作完成之后，数据库就只会使用新目录中的数据文件。如果需要这时可以使用手动删了旧数据文件。

使用表空间组来管理多个临时表空间

Posted on 2017年5月31日 by YongJing(敬勇)

使用表空间组来管理多个临时表空间

表空间组能让用户使用来自多个临时表空间中的临时空间。使用表空间组，而不是单个临时表空间，可以减少由于一个临时表空间没有足够的空间来处理排序而引发的问题。表空间组能让单个并行操作的并行执行服务器进程使用多个临时表空间。表空间组有以下特性:
.它包含至少一个临时表空间。对于一个表空间组可以包含的临时表空间数量没有限制。
.它共享命名空间，所以表空间组的名字不能与任何表空间名相同。
.当对数据库或用户指定缺省临时表空间时可以使用表空间组来代替。

我们不能显示创建一个表空间组，但可以在创建第一临时表空间时隐式来创建表空间组。当表空间组中的最后一个临时表空间被删除后，表空间组也会被删除。查询dba_tablespace_groups可以查看相关表空间组与相关的临时表空间。

创建表空间组
当执行create temporary tablespace或alter tablespace语句时通过指定tablespace group子句来隐式创建表空间组并且所指定的表空间组要在当前数据库中并不存在。例如，如果表空间组group1,group2不存在，那么下面的语句将会创建这两个表空间组，并且每个表空间组只有一个临时表空间存在。

SQL> create temporary tablespace temp2 tempfile '+DATA/JY/4B2C6373AE2547CCE053AB828A0A7CA3/TEMPFILE/temp2.dbf' size 50M tablespace group group1;

Tablespace created.

SQL> alter tablespace temp tablespace group group2;

Tablespace altered.


SQL> select * from dba_tablespace_groups;

GROUP_NAME                     TABLESPACE_NAME
------------------------------ ------------------------------
GROUP2                         TEMP
GROUP1                         TEMP2

更改表空间组成员
可以向现有表空间组增加临时表空间，这可以通过执行包含有tablespace group子句的create temporary tablespace或alter tablespace语句来完成。

下面的语句将向现有表空间组group1中增加一个临时表空间temp3，因些表空间组group1包含临时表空间temp2与temp3。

SQL> create temporary tablespace temp3 tempfile '+DATA/JY/4B2C6373AE2547CCE053AB828A0A7CA3/TEMPFILE/temp3.dbf' size 50M tablespace group group1;

Tablespace created.

SQL> select * from dba_tablespace_groups;

GROUP_NAME                     TABLESPACE_NAME
------------------------------ ------------------------------
GROUP2                         TEMP
GROUP1                         TEMP2
GROUP1                         TEMP3

下面的语句将向现有表空间组group2中增加一个临时表空间temp2，但因为临时表空间temp2已经存在，语句只是将临时表空间temp2从表空间组group1移到表空间组group2中。

SQL> select * from dba_tablespace_groups;

GROUP_NAME                     TABLESPACE_NAME
------------------------------ ------------------------------
GROUP2                         TEMP
GROUP2                         TEMP2
GROUP1                         TEMP3

现在表空间组group2包含临时表空间temp,temp2，表空间组group1只包含临时表空间temp3。

下面的语句将从表空间组group1中删除临时表空间temp3

SQL> alter tablespace temp3 tablespace group '';

Tablespace altered.

SQL> select * from dba_tablespace_groups;

GROUP_NAME                     TABLESPACE_NAME
------------------------------ ------------------------------
GROUP2                         TEMP
GROUP2                         TEMP2

临时表空间temp3不再属于任何表空间组。因此表空间组group1不包含任何临时表空间，因此隐式地删除了表空间组group1。

指定表空间组作为数据库的缺省临时表空间
通过执行alter database … default temporary tablespace语句来指定一个表空间组作为数据库的临时表空间。

SQL> SELECT PROPERTY_NAME, PROPERTY_VALUE FROM DATABASE_PROPERTIES WHERE PROPERTY_NAME='DEFAULT_TEMP_TABLESPACE';

PROPERTY_NAME                                       PROPERTY_VALUE
--------------------------------------------------  --------------------------------------------------
DEFAULT_TEMP_TABLESPACE                             TEMP



SQL> alter database default temporary tablespace group2;

Database altered.


SQL> SELECT PROPERTY_NAME, PROPERTY_VALUE FROM DATABASE_PROPERTIES WHERE PROPERTY_NAME='DEFAULT_TEMP_TABLESPACE';

PROPERTY_NAME                                       PROPERTY_VALUE
--------------------------------------------------  --------------------------------------------------
DEFAULT_TEMP_TABLESPACE                             GROUP2

任何没有显示指定临时表空间的用户，将可以使用临时表空间temp,temp2中的空间。当表空间组被指定作为数据库的临时表空间时，不能删除表空间组中的任何成员。要删除临时表空间必须首先要删除表空间组。同样不能删除作为数据库的缺省临时表空间。

Oracle 12CR2 Install the Sample Schemas

创建sample schemas只需执行db-sample-schemas-12.2.0.1目录下的mksample.sql脚本,其语法如下:

mksample          EXAMPLE TEMP $ORACLE_HOME/demo/schema/log/ localhost:1521/pdb

其参数分别指system,sys,hr,oe,pm,ix,sh,bi用户的密码，与缺省表空间，临时表空间名，以及存储生成日志文件的目录和连接数据库的连接串

关于ASM启动报无效用户名与密码的问题在MOS上有一篇相关文档”ASM not Starting With: ORA-01017: invalid username/password; logon denied (Doc ID 1918617.1)”，说原因是因为修改了sqlnet.ora文件，正确设置应该如下:

SQLNET.AUTHENTICATION_SERVICES= (NTS)

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

但我这里并不是这种情况，从另一篇文档”Oracle Restart – ASM Startup fails with PRCR-1079 (Doc ID 1904942.1)”找到类似的错误信息，说原因是因为ASM资源的ACL（访问控制列表)的权限发生了改变。

检查asm资源的访问控制列表权限

从上面的信息ACL=owner:grid:rwx,pgrp:asmdba:r-x,other::r–，可知组名(pgrp)变为了asmdba组,正常来说应该是grid用户的oinstall组，如果尝试修改:

[grid@jytest3 dbs]$ crsctl setperm resource ora.asm -g oinstall
CRS-4995:  The command 'Setperm  resource' is invalid in crsctl. Use srvctl for this command.

修改时出错了，在12.2.0.1中crsctl setperm命令是一种无效的crsctl，建议使用srvctl命令，但srvctl没有setperm命令，如是加上-unsupported参数再次执行修改:

[grid@jytest3 dbs]$ crsctl setperm resource ora.asm -g oinstall -unsupported

重启Oracle Restart，ASM实例正常启动

Oracle 12CR2 using create database command for create non-CDB rac database on Oracle Linux

Posted on 2017年4月21日2017年4月21日 by YongJing(敬勇)

在Oracle Linux7,数据库版本为12.2中使用create database来创建non-CDB数据库
1.设置实例标识符(SID)

[root@jytest1 ~]# su - oracle
Last login: Fri Apr 21 11:24:50 CST 2017
[oracle@jytest1 ~]$ export ORACLE_SID=orcl1

2.创建相关目录

ASMCMD [+data] > mkdir orcl
ASMCMD [+data] > ls
jy/
orcl/
ASMCMD [+data] > mkdir +data/orcl/CONTROLFILE
ASMCMD [+data] > mkdir +data/orcl/DATAFILE
ASMCMD [+data] > mkdir +data/orcl/ONLINELOG
ASMCMD [+data] > mkdir +data/orcl/TEMPFILE
ASMCMD [+data] > mkdir +data/orcl/PASSWORD
ASMCMD [+data] > mkdir +data/orcl/PARAMETERFILE

3.创建密码文件

[oracle@jytest1 dbs]$ orapwd file='/u01/app/oracle/product/12.2.0/db/dbs/orapworcl1'  force=y password=xxzx#7817600

4.创建参数文件,参数文件至少要包含db_name,control_files与memory_target参数

[oracle@jytest1 dbs]$ vi initorcl1.ora
db_name=orcl
control_files='+data/orcl/controlfile/control01.ctl','+data/orcl/controlfile/control02.c tl'
memory_target=1G

5.连接实例

[oracle@jytest1 dbs]$ sqlplus sys/xxzx#7817600 as sysdba

SQL*Plus: Release 12.2.0.1.0 Production on Wed Apr 19 19:15:50 2017

Copyright (c) 1982, 2016, Oracle.  All rights reserved.

Connected to an idle instance.

6.启动实例

SQL> startup nomount pfile='/u01/app/oracle/product/12.2.0/db/dbs/initorcl1.ora'
ORACLE instance started.

Total System Global Area 1073741824 bytes
Fixed Size                  8628936 bytes
Variable Size             750781752 bytes
Database Buffers          306184192 bytes
Redo Buffers                8146944 bytes

7.创建服务器参数文件spfile

SQL>create spfile='+DATA/orcl/PARAMETERFILE/spfileorcl.ora' from pfile='/u01/app/oracle/product/12.2.0/db/dbs/initorcl1.ora';

8.执行create database语句

SQL> CREATE DATABASE orcl
  2  USER SYS IDENTIFIED BY xxzx#7817600
  3  USER SYSTEM IDENTIFIED BY xxzx#7817600
  4  LOGFILE GROUP 1 ('+data/orcl/onlinelog/redo01.log') SIZE 100M BLOCKSIZE 512,
  5  GROUP 2 ('+data/orcl/onlinelog/redo02.log') SIZE 100M BLOCKSIZE 512,
  6  GROUP 3 ('+data/orcl/onlinelog/redo03.log') SIZE 100M BLOCKSIZE 512
  7  MAXLOGHISTORY 1
  8  MAXLOGFILES 16
  9  MAXLOGMEMBERS 3
 10  MAXDATAFILES 1024
 11  CHARACTER SET ZHS16GBK
 12  NATIONAL CHARACTER SET AL16UTF16
 13  EXTENT MANAGEMENT LOCAL
 14  DATAFILE '+data/orcl/datafile/system01.dbf'
 15  SIZE 700M REUSE AUTOEXTEND ON NEXT 10240K MAXSIZE UNLIMITED
 16  SYSAUX DATAFILE '+data/orcl/datafile/sysaux01.dbf'
 17  SIZE 550M REUSE AUTOEXTEND ON NEXT 10240K MAXSIZE UNLIMITED
 18  DEFAULT TABLESPACE users
 19  DATAFILE '+data/orcl/datafile/users01.dbf'
 20  SIZE 500M REUSE AUTOEXTEND ON MAXSIZE UNLIMITED
 21  DEFAULT TEMPORARY TABLESPACE tempts1
 22  TEMPFILE '+data/orcl/tempfile/temp01.dbf'
 23  SIZE 20M REUSE AUTOEXTEND ON NEXT 640K MAXSIZE UNLIMITED
 24  UNDO TABLESPACE undotbs1
 25  DATAFILE '+data/orcl/datafile/undotbs01.dbf'
 26  SIZE 200M REUSE AUTOEXTEND ON NEXT 5120K MAXSIZE UNLIMITED
 27  USER_DATA TABLESPACE usertbs
 28  DATAFILE '+data/orcl/datafile/usertbs01.dbf'
 29  SIZE 200M REUSE AUTOEXTEND ON MAXSIZE UNLIMITED;

Database created.

9.运行脚本来创建数据字典视图
用sys用户执行以下脚本

SQL> @$ORACLE_HOME/rdbms/admin/catalog.sql

Session altered.

SQL>@$ORACLE_HOME/rdbms/admin/catproc.sql

SQL> Rem END catproc.sql

SQL>@$ORACLE_HOME/rdbms/admin/utlrp.sql

SQL> Rem END utlrp.sql

使用system用户执行以下脚本

SQL>@$ORACLE_HOME/sqlplus/admin/pupbld.sql

SQL> alter session set "_ORACLE_SCRIPT" = false;

Session altered.

10.将数据库注册为RAC数据库,在节点2配置实例orcl2的参数文件

[oracle@jytest2 dbs]$ vi initorcl2.ora
SPFILE='+DATA/orcl/PARAMETERFILE/spfileorcl.ora'

设置RAC数据库所需要的相关参数

SQL> alter system set thread=1 scope=spfile sid='orcl1';

System altered.

SQL> alter system set thread=2 scope=spfile sid='orcl2';

System altered.

SQL> alter system set instance_number=1 scope=spfile sid='orcl1';

System altered.

SQL> alter system set instance_number=2 scope=spfile sid='orcl2';

System altered.

SQL> alter system set cluster_database=true scope=sfpile sid='*';

System altered.

SQL> alter system set cluster_database_instances=2 scope=sfpile sid='*';

System altered.

添加重做线程

SQL> alter database add logfile thread 2 group 4('+data/orcl/onlinelog/redo04.log') SIZE 100M BLOCKSIZE 512;

Database altered.

SQL> alter database add logfile thread 2 group 5('+data/orcl/onlinelog/redo05.log') SIZE 100M BLOCKSIZE 512;

Database altered.

SQL> alter database add logfile thread 2 group 6('+data/orcl/onlinelog/redo06.log') SIZE 100M BLOCKSIZE 512;

Database altered.

SQL> alter database enable thread 2;

Database altered.

向crs注册数据库

[oracle@jytest1 dbs]$ srvctl add database -db orcl -oraclehome  /u01/app/oracle/product/12.2.0/db/  -dbtype RAC -spfile  +DATA/orcl/PARAMETERFILE/spfileorcl.ora -diskgroup 'data'


[oracle@jytest1 dbs]$ srvctl add instance -db orcl -instance orcl1 -node jytest1
[oracle@jytest1 dbs]$ srvctl add instance -db orcl -instance orcl2 -node jytest2
[oracle@jytest1 dbs]$ srvctl config database -db orcl
Database unique name: orcl

11.将密码文件存储在ASM磁盘组中

[oracle@jytest1 dbs]$ orapwd file='+data/orcl/password/pwdorcl' dbuniquename='orcl'

Enter password for SYS:

ASMCMD [+data/orcl/password] > ls -lt
Type      Redund  Striped  Time             Sys  Name

PASSWORD  UNPROT  COARSE   APR 21 11:00:00  N    pwdorcl =>  +DATA/orcl/PASSWORD/pwdorcl.294.941886275

Enter password for SYS:
[oracle@jytest1 dbs]$ srvctl config database -db orcl
Database unique name: orcl
Database name:
Oracle home: /u01/app/oracle/product/12.2.0/db/
Oracle user: oracle
Spfile: +DATA/orcl/PARAMETERFILE/spfileorcl.ora

虽然，从监听与集群资源来看是正常，但因为这里pdb数据库（jypdb）使用的服务名与pdb数据库名相同，还有就是因为是RAC数据库，因为在RAC环境中，当PDB被mount时，实例将使用pdb数据库名向SCAN与本地监听程序注册PDB，如果使用SCAN IP来登录pdb数据库，就可能将连接请求指派给PDB只被mounted的实例(没有open)，如是检查pdb是否open，发现果然pdb在节点2上的实例没有被open，如是执行以下

查看rlzy实例的alert.log文件，可以看到以下错误信息“ORA-00600: internal error code, arguments: [2252], [3418], [573259345], [1594], [50675712]”，关于这个ORA-00600 2252在MOS上有相关bug描述，但我这并不是bug引起的，查看信息时我们也是需要关注时间的，这里时间显示为2001年1月1号了，与当前时间相差了16年2个多月。

查看系统当前时间,居然变成了2001年1月1号，而且奇怪的是并不是重启时时间就被修改了，因为有两个实例在重启之后正常启动了

[root@db1 ~]# date
Mon Jan  1 08:25:34 CST 2001

手工更新为当前时间后并手动启动实例(caiwu,rlzy)，就能正常启动

问题虽然解决了，但是为什么服务器会在启动两个实例后，系统时间发生改变还是不得而知，需要找浪潮服务器的工程师来检查。

Oracle Linux 7 Configure DNS

Posted on 2017年3月17日 by YongJing(敬勇)

Oracle Linux 7.1配置DNS服务
一.安装DNS需要的软件包

# yum install bind-libs bind bind-utils

二.编辑named.conf文件
在编辑前先复制一份named.conf文件

[root@jytest1 ~]# cp /etc/named.conf /etc/named.conf.backup


[root@jytest1 ~]# vi /etc/named.conf
//
// named.conf
//
// Provided by Red Hat bind package to configure the ISC BIND named(8) DNS
// server as a caching only nameserver (as a localhost DNS resolver only).
//
// See /usr/share/doc/bind*/sample/ for example named configuration files.
//

options {
        listen-on port 53 { any; };--将127.0.0.1修改成any
        listen-on-v6 port 53 { ::1; };
        directory       "/var/named";
        dump-file       "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
        memstatistics-file "/var/named/data/named_mem_stats.txt";
        allow-query     { any; };--将127.0.0.1修改成any

        /* 
         - If you are building an AUTHORITATIVE DNS server, do NOT enable recursion.
         - If you are building a RECURSIVE (caching) DNS server, you need to enable 
           recursion. 
         - If your recursive DNS server has a public IP address, you MUST enable access 
           control to limit queries to your legitimate users. Failing to do so will
           cause your server to become part of large scale DNS amplification 
           attacks. Implementing BCP38 within your network would greatly
           reduce such attack surface 
        */
        recursion yes;

        dnssec-enable yes;
        dnssec-validation yes;
        dnssec-lookaside auto;

        /* Path to ISC DLV key */
        bindkeys-file "/etc/named.iscdlv.key";

        managed-keys-directory "/var/named/dynamic";

        pid-file "/run/named/named.pid";
        session-keyfile "/run/named/session.key";
};

logging {
        channel default_debug {
                file "data/named.run";
                severity dynamic;
        };
};

zone "." IN {
        type hint;
        file "named.ca";
};
include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";

三.配置host.conf

[root@jytest1 ~]# cat /etc/host.conf
multi on

该文件指定如何解析主机名。Linux通过解析器库来获得主机名对应的IP地址。下面是一个“/etc/host.conf”的示例：
order bind,hosts
multi on
nospoof on
“order bind,hosts”指定主机名查询顺序，这里规定先使用DNS来解析域名，然后再查询“/etc/hosts”文件(也可以相反)。
“multi on”指定是否“/etc/hosts”文件中指定的主机可以有多个地址，拥有多个IP地址的主机一般称为多穴主机。
“nospoof on”指不允许对该服务器进行IP地址欺骗。IP欺骗是一种攻击系统安全的手段，通过把IP地址伪装成别的计算机，来取得其它计算机的信任。

四.修改/etc/named.rfc1912.zones

[root@jytest1 ~]# cp /etc/named.rfc1912.zones /etc/named.rfc1912.zones.backup
[root@jytest1 ~]# vi /etc/named.rfc1912.zones
// named.rfc1912.zones:
//
// Provided by Red Hat caching-nameserver package
//
// ISC BIND named zone configuration for zones recommended by
// RFC 1912 section 4.1 : localhost TLDs and address zones
// and http://www.ietf.org/internet-drafts/draft-ietf-dnsop-default-local-zones-02.txt
// (c)2007 R W Franks
//
// See /usr/share/doc/bind*/sample/ for example named configuration files.
//

zone "localhost.localdomain" IN {
        type master;
        file "named.localhost";
        allow-update { none; };
};

zone "localhost" IN {
        type master;
        file "named.localhost";
        allow-update { none; };
};

zone "1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa" IN {
        type master;
        file "named.loopback";
        allow-update { none; };
};

zone "1.0.0.127.in-addr.arpa" IN {
        type master;
        file "named.loopback";
        allow-update { none; };
};

zone "0.in-addr.arpa" IN {
        type master;
        file "named.empty";
        allow-update { none; };
};

--下面为增加的内容，jybd.net.forward为正向解析,jydba.net.reverse为反向解析
zone "jydba.net" IN {
        type master;
        file "jydba.net.forward";
        allow-update { none; };
};

zone "130.138.10.in-addr.arpa" IN {
        type master;
        file "jydba.net.reverse";
        allow-update { none; };
};
"/etc/named.rfc1912.zones" 54L, 1171C written

五.修改具体的zone配置文件

[root@jytest1 named]# cd /var/named
[root@jytest1 named]# cp named.localhost jydba.net.forward
[root@jytest1 named]# cp named.loopback jydba.net.reverse

[root@jytest1 named]# vi jydba.net.forward
$TTL 1D
@       IN SOA  @ root.jydba.net. (
                                        0       ; serial
                                        1D      ; refresh
                                        1H      ; retry
                                        1W      ; expire
                                        3H )    ; minimum
        NS      @

[root@jytest1 named]# vi jydba.net.reverse
$TTL 1D
@       IN SOA  @ root.jydba.net. (

                                        1H      ; retry
                                        1W      ; expire
                                        3H )    ; minimum
        NS      @

178           PTR     jytest-scan
179           PTR     jytest-scan

六.配置resolv.conf

[root@jytest1 named]# cat /etc/resolv.conf
# Generated by NetworkManager
search jydba.net


# No nameservers found; try putting DNS servers into your
# ifcfg files in /etc/sysconfig/network-scripts like so:
#
# DNS1=xxx.xxx.xxx.xxx
# DNS2=xxx.xxx.xxx.xxx
# DOMAIN=lab.foo.com bar.foo.com
search jydba.net
nameserver       10.138.130.171

通过测试可以看到DNS通过正向与反向解析都是正常的，说明配置成功。

注意:
对于Linux 使用NetworkManager来控制网络的操作系统，当主机重启之前/etc/resolv.conf文件可能会被重写。如果发生这种情况，需要对相应的网卡配置文件增加以下记录
对于Oracle Linux 6修改类似文件 /etc/sysconfig/network-scripts/ifcfg-eth0 (ifcfg-eth1 etc.)
对于Oracle Linux 7修改类似文/etc/sysconfig/network-scripts/ifcfg-ens160 (ifcfg-ens34 etc.)

Oracle Linux 7.1 增加网卡及IP配置

Posted on 2017年3月16日 by YongJing(敬勇)

由于需要给虚拟机(oracle linux 7.1)增加网卡并设置IP操作,在增加网卡后执行ifconfig命令可以看到增加的网卡信息，但没有生成网卡配置文件

可以看到并没有生成网卡配置文件ifcfg-ens34,而之前在创建虚拟机时增加的网卡ens160是有相应的配置文件ifcfg-ens160。在oracle linux 7.1中使用nmtui来设置网络，nmtui 属于curses-based text user interface（文本用户界面)，类似Linux7以前的setup工具

[root@jytest1 ~]# nmtui

使用nmtui设置完后可以看到生成了网卡ens34的配置文件ifcfg-ens34
