Linux程序开机自启动(以zookeeper为例)

1. 在/etc/rc.d/init.d 目录下创建脚本, 例如 zookeeper.sh, 内容如下

   #!/bin/bash
   #chkconfig: 2345 10 90
   #description: service zookeeper
   #process name:zookeeper
   
   #环境变量加载
   source /etc/profile
   export JAVA_HOME=/opt/module/jdk1.8.0_341
   export ZOOKEEPER_HOME=/opt/module/zookeeper-3.5.7
   
   case "$1" in
       start) su root ${ZOOKEEPER_HOME}/bin/zkServer.sh start;;
       stop) su root ${ZOOKEEPER_HOME}/bin/zkServer.sh stop;;
       status) su root ${ZOOKEEPER_HOME}/bin/zkServer.sh status;;
       restart) su root ${ZOOKEEPER_HOME}/bin/zkServer.sh restart;;
       *) echo "require start|start-foreground|stop|status|restart|print-cmd";;
   esac

2. 添加到开机自启动服务(关键)

   # 上面相当于创建了一个zookeeper.sh脚本, 添加到开机自启动服务相当于调用zookeeper.sh start命令
   chkconfig --add zookeeper

3. 查看开机自启动服务

   chkconfig --list

   

4. 使用 systemctl start zookeeper 命令来启动服务, 或者使用systemctl status zookeeper命令来查看服务运行状态
