nginx 相关文件位置

/usr/sbin/nginx：主程序
/etc/nginx：存放配置文件
/usr/share/nginx：存放静态文件
/var/log/nginx：存放日志

常用命令

nginx -t                  # 查看nginx状态
nginx -s reload           # 重新载入配置文件
nginx -s reopen           # 重启 Nginx
nginx -s stop             # 停止 Nginx

nginx 配置文件

文件位置： /etc/nginx/nginx.conf

初始 nginx.conf 文件内容为 demo 内容，根据情况修改。

上面是主要配置文件，这里把 server 的配置部分单独拿出来，放到 /etc/nginx/conf.d/test.conf 文件中，test.conf 是你新建的 server 配置文件（名称看着取）。

引入单独的 server 配置文件：include /etc/nginx/conf.d/*.conf 

nginx server 配置

文件位置：/etc/nginx/conf.d/test.conf 

server {
    # 端口号
    listen 80;
    # 域名 如果没有域名填服务器ip地址
    server_name 47.102.195.218;

    index index.html index.htm;

    access_log /var/log/nginx/freedom01.access.log main;
    error_log /var/log/nginx/freedom01.error.log warn;

    location / {
        # 对应的静态资源目录
        root /data/www/test/freedom01/dist;
        index index.html index.htm;
        if (!-e $request_filename) {
            rewrite ^ /(.*) /index.html last;
            break;
        }
    }

    # 后台接口地址以 /api 开头
    location /api {
        limit_except GET POST {
            deny all;
        }
        proxy_http_version 1.1;
        proxy_set_header Connection "";
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy true;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        # 以 /api 开头的请求转发到本服务器3000端口/api
        proxy_pass http://127.0.0.1:3000/api;
        proxy_redirect off;
    }}
}

常见报错

1. 执行 nginx -s reload 报错 nginx: [error] invalid PID number

解决方法：执行 nginx -c /etc/nginx/nginx.conf

如果还没解决，参考 blog.csdn.net/PT1993/arti…

2. nginx 出现 403 Forbidden

解决方案：

方案1：nginx.conf 文件中的 user 和启动用户不一致，设置为一致即可；

方案2：nginx 没有 web 目录的操作权限，修改 web 目录的读写权限，重启 nginx 即可；

chmod -rw 777
