centos 7的Service与systemctl

似乎centos7之后（我的是7.3）把service命令给干掉了，有文章 说统一使用systemctl命令了。

下面记录下systemctl的使用：

• 列出所有可用单元

systemctl list-unit-files

• 列出所有运行中单元

• systemctl list-units

  检查某个单元是否启用

systemctl is-enabled MysqLd.service

查看某个服务（单元）的状态

systemctl status MysqLd.service

• 启动、关闭、重启服务

# systemctl start httpd.service
# systemctl restart httpd.service
# systemctl stop httpd.service
# systemctl reload httpd.service

*激活/禁止自动启动

# systemctl enable httpd.service
# systemctl disable httpd.service

• *杀死服务

• #systemctl kill httpd
