Oracle Linux 7.1 透過systemctl將Weblogic設定為開機自啟動

1 說明
設定開機自啟動，需要用到systemctl工具。systemctl是一個systemd工具，主要負責控制systemd系統和服務管理器。systemd是一個系統管理守護程式、工具和庫的集合，用於取代System V初始程式。Systemd的功能是用於集中管理和配置類UNIX系統。

2 準備
作業系統：Oracle Linux 7.1
systemctl --version ： systemd 208
weblogic version：12.2.1.3.0
3 編寫系統服務檔案
3.1 adminserver 系統服務檔案

[root@localhost system]# vi weblogic.service
[Unit]
Description=WebLogic Adminserver Service[Service]
[Service]
Type=simple
WorkingDirectory=/weblogic/Oracle/Middleware/user_projects/domains/base_domain
ExecStart=/weblogic/Oracle/Middleware/user_projects/domains/base_domain/bin/startWebLogic.sh
ExecStop=/weblogic/Oracle/Middleware/user_projects/domains/base_domain/bin/stopWebLogic.sh
User=weblogic
Group=weblogic
[Install]
WantedBy=multi-user.target

3.2 配置weblogic將日誌輸出到指定檔案${DOMAIN_HOME}/admin.log，也就是在以下命令後面加上>"${DOMAIN_HOME}/admin.log" 2>&1

[weblogic@localhost bin]$ vi startWebLogic.sh
if [ "${WLS_REDIRECT_LOG}" = "" ] ; then
        echo "Starting WLS with line:"
        echo "${JAVA_HOME}/bin/java ${JAVA_VM} ${MEM_ARGS} ${LAUNCH_ARGS} -Dweblogic.Name=${SERVER_NAME} -Djava.security.policy=${WLS_POLICY_FILE} ${JAVA_OPTIONS} ${PROXY_SETTINGS} ${SERVER_CLASS}"
        ${JAVA_HOME}/bin/java ${JAVA_VM} ${MEM_ARGS} ${LAUNCH_ARGS} -Dweblogic.Name=${SERVER_NAME} -Djava.security.policy=${WLS_POLICY_FILE} ${JAVA_OPTIONS} ${PROXY_SETTINGS} ${SERVER_CLASS} >"${DOMAIN_HOME}/admin.log"  2>&1
else
        echo "Redirecting output from WLS window to ${WLS_REDIRECT_LOG}"
        ${JAVA_HOME}/bin/java ${JAVA_VM} ${MEM_ARGS} ${LAUNCH_ARGS} -Dweblogic.Name=${SERVER_NAME} -Djava.security.policy=${WLS_POLICY_FILE} ${JAVA_OPTIONS} ${PROXY_SETTINGS} ${SERVER_CLASS}  >"${DOMAIN_HOME}/admin.log"  2>&1

3.3 檢視系統服務檔案是否被識別

[root@localhost system]# systemctl list-unit-files|grep weblogic
weblogic.service                            disabled
3.4 禁用防火牆和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.
SELINUX=disabled
# 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.
SELINUXTYPE=targeted
[root@localhost system]# systemctl is-enabled firewalld

4 測試系統服務
4.1 啟動系統服務

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

4.2 停止系統服務

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

5 將服務設定成開機自啟動

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

反向命令：

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

6 重啟伺服器並檢查weblogic是否自啟動

[root@localhost system]#reboot
