systemctl命令是系统服务管理器指令,它实际上将 service 和 chkconfig 这两个命令组合到一起。
| 任务 | 旧指令 | 新指令 |
|---|---|---|
| 使某服务自动启动 | chkconfig –level 3 httpd on | systemctl enable httpd.service |
| 使某服务不自动启动 | chkconfig –level 3 httpd off | systemctl disable httpd.service |
| 检查服务状态 | service httpd status | systemctl status httpd.service (服务详细信息) systemctl is-active httpd.service (仅显示是否 Active) |
| 显示所有已启动的服务 | chkconfig –list | systemctl list-units –type=service |
| 启动某服务 | service httpd start | systemctl start httpd.service |
| 停止某服务 | service httpd stop | systemctl stop httpd.service |
| 重启某服务 | service httpd restart | systemctl restart httpd.service |
| 删除某服务 | chkconfig —del xxx | 停掉应用,删除相应的配置文件 |
