Oracle Linux 7.1 通过systemctl将Weblogic设置为开机自启动

1 说明
设置开机自启动,需要用到systemctl工具。systemctl是一个systemd工具,主要负责控制systemd系统和服务管理器。systemd是一个系统管理守护进程、工具和库的集合,用于取代System V初始进程。Systemd的功能是用于集中管理和配置类UNIX系统。

2 准备
操作系统:Oracle Linux 7.1
systemctl –version : systemd 208
weblogic version:
3 编写系统服务文件
3.1 adminserver 系统服务文件

[root@localhost system]# vi weblogic.service
Description=WebLogic Adminserver Service[Service]

3.2 配置weblogic将日志输出到指定文件${DOMAIN_HOME}/admin.log,也就是在以下命令后面加上>”${DOMAIN_HOME}/admin.log” 2>&1

[weblogic@localhost bin]$ vi
if [ "${WLS_REDIRECT_LOG}" = "" ] ; then
        echo "Starting WLS with line:"
        echo "Redirecting output from WLS window to ${WLS_REDIRECT_LOG}"

3.3 查看系统服务文件是否被识别

[root@localhost system]# systemctl list-unit-files|grep weblogic
weblogic.service                            disabled

3.4 禁用防火墙和SELinux
[root@localhost system]# setenforce 0
[root@localhost system]# sed -i "/^SELINUX=/s#enforcing#disabled#" /etc/selinux/config
[root@localhost system]# cat /etc/selinux/config

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
# SELINUXTYPE= can take one of three two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected.
#     mls - Multi Level Security protection.
[root@localhost system]# systemctl is-enabled firewalld

4 测试系统服务
4.1 启动系统服务

[root@localhost system]# systemctl start weblogic.service

[root@localhost base_domain]# tail -f admin.log

4.2 停止系统服务

[root@localhost system]# systemctl stop weblogic.service

5 将服务设置成开机自启动

[root@localhost system]# systemctl enable weblogic.service
ln -s '/etc/systemd/system/weblogic.service' '/etc/systemd/system/'
[root@localhost system]# systemctl list-unit-files|grep weblogic
weblogic.service                            enabled


[root@localhost system]# systemctl disable weblogic.service
rm '/etc/systemd/system/'
[root@localhost system]# systemctl list-unit-files|grep weblogic
weblogic.service                            disabled

6 重启服务器并检查weblogic是否自启动

[root@localhost system]#reboot

[root@localhost ~]# ps -ef | grep java
