centos 7 中的类似"service httpd start"服务启动，停止，重启指令，“service”已更改为“systemctl”。具体示例如下：
systemctl start httpd.service 启动Apache httpd
systemctl restart httpd.service 重新启动
systemctl stop httpd.service 停止服务
同样类似"chkconfig httpd on"设置服务开机启动项，指令已更改为“systemctl enable”，具体示例如下：
systemctl enable httpd.service 开机启动httpd
systemctl disable httpd.service 禁止开机启动httpd
