centos7启动httpd命令有两个可以用
service httpd start systemctl start httpd.service
如果出现如下报错
Job for httpd.service failed because the control process exited with error code. See “systemctl status httpd.service” and “journalctl -xe” for details.
应该是端口被占用，查看端口
netstat -antlp | grep 80
是nginx占用了端口
systemctl stop nginx.service 停用nginx即可
如果想开机关闭nginx则输入命令 systemctl disable nginx
