linux 添加系统服务（zookeeper举例）

zookeeper添加系统服务

1、vi  /etc/systemd/system/zookeeper.service 添加服务

[Unit]
Description=zookeeper
After=network.target

[Service]
Type=forking
Environment=JAVA_HOME=/var/local/jdk1.8.0_371
ExecStart=/data/apache-zookeeper-3.7.1-bin/bin/zkServer.sh start
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/data/apache-zookeeper-3.7.1-bin/bin/zkServer.sh stop
PrivateTmp=true

[Install]
WantedBy=multi-user.target

备注：
[service]
Type 服务启动类型 forking：后台启动
Environment 为依赖的环境，“/var/local/jdk1.8.0_371”是自己jdk的安装路径
ExecStart 定义启动的命令，“/data/apache-zookeeper-3.7.1-bin/” 为自己的zookeeper安装路径，“-daemon”：台启动
ExecReload 定义重启命令，“/bin/kill -s HUP $MAINPID” 通用重启命令
ExecStop 定义停止命令
PrivateTmp 是否分配独立空间

2、刷新配置
systemctl daemon-reload
3、启动zookeeper服务
#启动
systemctl start zookeeper
#查看状态
systemctl status zookeeper 
#停止
systemctl stop zookeeper
4、将zookeeper加入开机服务
systemctl enable zookeeper
