测试启动nginx

/usr/local/nginx/sbin/nginx -t

systemctl start nginx
#或
/usr/local/nginx/sbin/nginx

centos7防火墙开放端口

# 开放8080端口
firewall-cmd --zone=public --add-port=8080/tcp --permanent
#重载
firewall-cmd --reload
#查看状态
firewall-cmd --list-all

阿里云端口安全组设置

安全组说明
新增8080端口的新增【入方向】规则

测试

打开 xxx.xxx.xxx.xxx:8080
如果有出现 【Welcome to nginx!】 即成功了
