Centos7的Nginx配置

1 Centos7上Nginx配置

1.1 nginx位置

通过whereis 命令查询可得

[fanbi@VM_0_12_centos ~]$ whereis nginx
nginx: /usr/bin/nginx /usr/sbin/nginx /usr/lib64/nginx /etc/nginx /usr/share/nginx /usr/share/man/man8/nginx.8.gz
[fanbi@VM_0_12_centos ~]$

• /etc/nginx是其安装目录

• /usr/sbin/nginx是其运行程序

• usr/share/nginx是默认读取位置，若没其它配置，则读取其下面的index.html文件

• 具体配置和宝塔Linux面板上Nginx配置是一样的

2 宝塔Linux面板上Nginx配置

2.1 server

2.1.1 HTTP

   listen 80;
      server_name unionline.top;
      index index.php index.html index.htm default.php default.htm default.html;
      root /www/wwwroot/unionline.top;
      
    location ~ .*.(gif|jpg|jpeg|png|bmp|swf)$
    {
        expires      30d;
        error_log off;
        access_log off;
    }
    
    location ~ .*.(js|css)?$
    {
        expires      12h;
        error_log off;
        access_log off; 
    }
    access_log  /www/wwwlogs/unionline.top.log;
    error_log  /www/wwwlogs/unionline.top.error.log;

2.1.2 HTTPS

# HTTPS server
server {
  listen       443;
  server_name  unionline.top;
  root   /www/wwwroot/unionline.top;
  index  index.html index.htm;
  
  ssl on;

  ssl_certificate      1_www.unionline.top_bundle.crt;
  ssl_certificate_key  2_www.unionline.top.key;

  ssl_session_cache    shared:SSL:1m;
  ssl_session_timeout  5m;

  ssl_protocols TLSv1 TLSv1.1 TLSv1.2; #按照这个协议配置
  ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE;#按照这个套件配置
  ssl_prefer_server_ciphers on;
  
  #ERROR-PAGE-START  错误页配置，可以注释、删除或修改
  error_page 404 /404.html;
  error_page 502 /502.html;
  #ERROR-PAGE-END
  
  #PHP-INFO-START  PHP引用配置，可以注释或修改
  include enable-php-56.conf;
  #PHP-INFO-END

	#默认是blog为主页
  location / {
          proxy_pass http://182.254.111.234:4000/;
 			#root /your_project_dir/blog/myHexoBlog/public;
          location ~ .*.(css|js)$ {
             root /your_project_dir/blog/myHexoBlog/public;
             if (-f $request_filename) {
                  expires 1d;
                  break;
                  }
              }
      }

 

 location /blog/ {
          proxy_pass https://182.254.111.234:4000/;
      }

 location /html/ {
         	root /www/wwwroot/unionline.top/;
  		index index.html ;
  
         location ~ .*.(gif|jpg|jpeg|png|bmp|swf|css|js|eot|svg|ttf|woff|woff2)$ {
              root /www/wwwroot/unionline.top/;
             if (-f $request_filename) {
                  expires 1d;
                  break;
                  }
              }
      }
}

2.1.3 重定向

  {
      listen 80;
      large_client_header_buffers 4 128k;
  	  server_name www.unionline.top;

      location / {
      #开启对http1.1支持
      proxy_http_version 1.1;
      
      #设置Connection为空串,以禁止传递头部到后端
      #http1.0中默认值Connection: close
      proxy_set_header Connection "";
      
      proxy_pass http://unionline.top;
    }

2.1.4 http跳转https

server
{
  # 80端口是http正常访问的接口
  listen 80;
  server_name _;
  # 在这里，我做了https全加密处理，在访问http的时候自动跳转到https
  rewrite ^(.*)$ https://$host$1 permanent; #这行是关键
}

3.2 http

略

4 问题

4.1 Nginx 一个服务器多域名配置 以及 访问php文件直接下载而不运行

include enable-php.conf; 这句话起到了关键作用

location ~ [^/].php(/|$)
        {
            try_files $uri =404;
            fastcgi_pass  unix:/tmp/php-cgi.sock;
            fastcgi_index index.php;
            include fastcgi.conf;
        }

4.2 403错误

通过查看对应的error.log，主要原因有

1. 项目路径无index.html index.php等等文件
2. 项目js/css等路径不正确
3. 权限不够 (nginx failed (13: Permission denied))
   • /www/server/nginx/conf/nginx.conf 中user拥有者和组别分别是www www，而项目是root或者fanbi的拥有着，改成user root root即可
   • 通过宝塔面板新建的项目默认用户是www，组别是www
