1.需要在安全组规则里面开发8080规则
2.开放8080端口：
firewall-cmd --add-port=8080/tcp --permanent
firewall-cmd --query-port=8080/tcp
systemctl stop firewalld.service
systemctl start firewalld.service
3.在nginx配置文件里面配置listen 8080
重启报502 Bad Gateway [error] 9375#0: *11 connect() failed (111: Connection refused) while connection
这是重启没启动启动php-fpm
重启ok
