Linux设置zookeeper开机自启

1.创建目录
在etc/systemd/system目录下创建zookeeper.service文件,该文件文件名可以随便起,后缀.service不可改变
2.在文件内编写

[Unit]
Description=Zookeeper-2181
After=network.target

[Service]
Type=forking
Environment=ZOO_LOG_DIR=/usr/local/zookeeper-2181/log
Environment=PATH=/usr/local/java/jdk1.8/bin:/usr/local/java/jdk1.8/jre/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/root/bin
PIDFile=/usr/local/zookeeper-2181/data/zookeeper_server.pid
ExecStart=/usr/local/zookeeper-2181/bin/zkServer.sh start
ExecStop=/usr/local/zookeeper-2181/bin/zkServer.sh stop
ExecReload=/usr/local/zookeeper-2181/bin/zkServer.sh restart

[Install]
WantedBy=multi-user.target

其中[Service]下的zookeeper-2181为zookeeper文件目录
3.重新加载系统服务
使用命令systemctl daemon-reload
4.设置开机自启
使用命令systemctl enable zookeeper.service,enable后跟的是刚才创建的文件名
5.关闭开机自启
使用命令systemctl disable zookeeper.service,enable后跟的是刚才创建的文件名
