三、systemctl 基本操作
systemctl start zookeeper.service #启动服务
systemctl status zookeeper #查看服务状态
systemctl stop zookeeper.service #停止服务
systemctl daemon-reload #修改service文件后要重新加载
systemctl enable zookeeper.service#加入开机自启动
systemctl disable zookeeper.service #取消开机自启动
systemctl list-unit-files |grep enabled #查看所有开机启动项目
四、启动日志查看
journalctl -u zookeeper.service
更多journalctl 使用方法详见参考文档
