CentOS 安装 Nginx 并配置开机自启（简洁版）

前言

简单记录一下 CentOS 安装 Nginx、配置代理、设置开机自启，纯干货，复制即用。

一、安装 Nginx

yum install -y nginx

二、启动 Nginx

systemctl start nginx

三、设置开机自启（重要）

systemctl enable nginx

四、修改 Nginx 配置

vi /etc/nginx/nginx.conf

直接替换成下面内容：

nginx

worker_processes 1; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; server { listen 80; server_name localhost; location / { proxy_pass http://127.0.0.1:8443; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } } }

五、重启 Nginx 生效

systemctl restart nginx

六、放行 80 端口（防火墙开启才执行）

firewall-cmd --add-service=http --permanent firewall-cmd --reload

常用命令

启动：systemctl start nginx 停止：systemctl stop nginx 重启：systemctl restart nginx 查看状态：systemctl status nginx 开机自启：systemctl enable nginx 关闭自启：systemctl disable nginx
