Linux下使用systemctl命令

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 chkconfig --level 3 httpd on 来自: http://man.linuxde.net/systemctl	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) systemctl disable httpd.service 来自: http://man.linuxde.net/systemctl
显示所有已启动的服务	chkconfig --list	systemctl list-unit-files|grep enabled
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 restar	systemctl restart httpd.service
