apache、nginx实现反向代理

一、apache（不推荐）：

1. 代理80端口：
   a. 配置：
   
   b. 效果：
   
   c. 配置文件参考：

   ServerRoot "/etc/httpd"
   Listen 80
   ProxyPass / http://admin.dollarphp.com/
   ProxyPa***everse / http://admin.dollarphp.com/
   Include conf.modules.d/*.conf
   User apache
   Group apache
   ServerAdmin root@localhost
   
   AllowOverride none
   Require all denied
   
   DocumentRoot "/var/www/html"
   
   AllowOverride None
   Require all granted
   
   
   Options Indexes FollowSymLinks
   AllowOverride None
   Require all granted
   
   
   DirectoryIndex index.html
   
   
   Require all denied
   
   ErrorLog "logs/error_log"
   LogLevel warn
   
   LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined
   LogFormat "%h %l %u %t \"%r\" %>s %b" common
   
     LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" %I %O" combinedio
   
   CustomLog "logs/access_log" combined
   
   
   ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"
   
   
   AllowOverride None
   Options None
   Require all granted
   
   
   TypesConfig /etc/mime.types
   AddType application/x-compress .Z
   AddType application/x-gzip .gz .tgz
   AddType text/html .shtml
   AddOutputFilter INCLUDES .shtml
   
   AddDefaultCharset UTF-8
   
   MIMEMagicFile conf/magic
   
   EnableSendfile on
   IncludeOptional conf.d/*.conf

2. 代理443端口：
   a. 安装mod_ssl：

   yum  -y  install  mod_ssl

   b. 配置：
   
   c. 效果：
   
   d. 配置文件参考：

   ServerRoot "/etc/httpd"
   Listen 80
   SSLProxyEngine on
   ProxyPass / https://www.baidu.com/
   ProxyPa***everse / https://www.baidu.com/
   Include conf.modules.d/*.conf
   User apache
   Group apache
   ServerAdmin root@localhost
   
   AllowOverride none
   Require all denied
   
   DocumentRoot "/var/www/html"
   
   AllowOverride None
   Require all granted
   
   
   Options Indexes FollowSymLinks
   AllowOverride None
   Require all granted
   
   
   DirectoryIndex index.html
   
   
   Require all denied
   
   ErrorLog "logs/error_log"
   LogLevel warn
   
   LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined
   LogFormat "%h %l %u %t \"%r\" %>s %b" common
   
     LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" %I %O" combinedio
   
   CustomLog "logs/access_log" combined
   
   
   ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"
   
   
   AllowOverride None
   Options None
   Require all granted
   
   
   TypesConfig /etc/mime.types
   AddType application/x-compress .Z
   AddType application/x-gzip .gz .tgz
   AddType text/html .shtml
   AddOutputFilter INCLUDES .shtml
   
   AddDefaultCharset UTF-8
   
   MIMEMagicFile conf/magic
   
   EnableSendfile on
   IncludeOptional conf.d/*.conf

   二、nginx（同时适用于80端口和443端口）：

3. 配置：
   
4. 配置文件参考：

   user nginx;
   worker_processes auto;
   error_log /var/log/nginx/error.log;
   pid /run/nginx.pid;
   include /usr/share/nginx/modules/*.conf;
   events {
   worker_connections 1024;
   }
   http {
   log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                     '$status $body_bytes_sent "$http_referer" '
                     '"$http_user_agent" "$http_x_forwarded_for"';
   access_log  /var/log/nginx/access.log  main;
   sendfile            on;
   tcp_nopush          on;
   tcp_nodelay         on;
   keepalive_timeout   65;
   types_hash_max_size 2048;
   include             /etc/nginx/mime.types;
   default_type        application/octet-stream;
   include /etc/nginx/conf.d/*.conf;
   server {
       listen       80 default_server;
       listen       [::]:80 default_server;
       server_name  _;
       root         /usr/share/nginx/html;
       include /etc/nginx/default.d/*.conf;
       location / {
           proxy_pass https://www.baidu.com;
       }
       error_page 404 /404.html;
           location = /40x.html {
       }
       error_page 500 502 503 504 /50x.html;
           location = /50x.html {
       }
   }
   }
