说明
在Centos7里,管理系统服务被systemctl命令取代。实际上将 service 和 chkconfig 这两个命令组合到一起。
格式
systemctl [option] [service name]
新旧命令的对比表

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 |
查看开机自启项
systemctl list-unit-files
