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 |
---|---|---|
使某服务自启 | 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 或者 systemctl is-active httpd.service |
显示所有已启动服务 | 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 |
