5.启动准备

# 验证配置文件是否正确
/usr/local/nginx/sbin/nginx -t
# 启动
/usr/local/nginx/sbin/nginx
提示

启动完成， 访问一下公网IP地址。

访问不通检查一下服务器安全组和防火墙是否开启80端口；

删除安装包​

rm -rf /opt/nginx-1.22.1
附 生命周期命令
/usr/local/nginx/sbin/nginx # 启动nginx（默认加载../conf/nginx.conf）
/usr/local/nginx/sbin/nginx -c /path/nginx.conf # 启动nginx，指定配置文件
/usr/local/nginx/sbin/nginx -t -c /path/nginx.conf # 测试该nginx配置文件是否正确
/usr/local/nginx/sbin/nginx -s reload            # 重新载入配置文件
/usr/local/nginx/sbin/nginx -s reopen            # 重新打开日志文件
/usr/local/nginx/sbin/nginx -s stop              # 停止 Nginx

安装完成​

将nginx加入到开机启动

vi /etc/rc.local 在里面添加内容/usr/local/nginx/sbin/nginx
