我停止服务/usr/lib/systemd/system/zookeeper.service失败。

[vagrant@localhost ~]$ sudo systemctl stop zookeeper
[vagrant@localhost ~]$ sudo systemctl status zookeeper

完整的服务代码：

[Unit]
Description=Zookeeper Distributed Coordination Server
Documentation=http://zookeeper.apache.org
After=network.target
Wants=network.target

[Service]
Type=forking
User=zookeeper
Group=zookeeper
WorkingDirectory=/opt/zookeeper
Environment=ZOO_LOG_DIR=/var/log/zookeeper
ExecStart=/opt/zookeeper/bin/zkServer.sh start
ExecStop=/opt/zookeeper/bin/zkServer.sh stop
Restart=on-failure

[Install]
WantedBy=multi-user.target

启动服务后，一切正常：

[vagrant@localhost ~]$ sudo systemctl start zookeeper
[vagrant@localhost ~]$ sudo systemctl status zookeeper

Answer 1

将ExecStop更改为使用/bin/kill，然后将PIDFile指向.pid文件：

[Unit]
Description=Zookeeper Distributed Coordination Server
Documentation=http://zookeeper.apache.org
After=network.target

[Service]
Type=forking
User=zookeeper
Group=zookeeper
WorkingDirectory=/opt/zookeeper
Environment=ZOO_LOG_DIR=/var/log/zookeeper
ExecStart=/opt/zookeeper/bin/zkServer.sh start
PIDFile=/var/lib/zookeeper/zookeeper_server.pid
ExecStop=/bin/kill $MAINPID
SuccessExitStatus=1 143
Restart=on-failure

[Install]
WantedBy=multi-user.target

不要忘记将SuccessExitStatus更改为代码1 143。

Answer 2

对我来说最有用的是：

ExecStop=/bin/kill -s SIGKILL $MAINPID
SuccessExitStatus=SIGKILL

停止时系统服务失败
