Apache反向代理

一、Mac 自带apache服务器

终端执行apachectl -h查看相应指令：

Usage: /usr/sbin/httpd [-D name] [-d directory] [-f file]
                       [-C "directive"] [-c "directive"]
                       [-k start|restart|graceful|graceful-stop|stop]
                       [-v] [-V] [-h] [-l] [-L] [-t] [-T] [-S] [-X]
Options:
  -D name            : define a name for use in <IfDefine name> directives
  -d directory       : specify an alternate initial ServerRoot
  -f file            : specify an alternate ServerConfigFile
  -C "directive"     : process directive before reading config files
  -c "directive"     : process directive after reading config files
  -e level           : show startup errors of level (see LogLevel)
  -E file            : log startup errors to file
  -v                 : show version number
  -V                 : show compile settings
  -h                 : list available command line options (this page)
  -l                 : list compiled in modules
  -L                 : list available configuration directives
  -t -D DUMP_VHOSTS  : show parsed vhost settings
  -t -D DUMP_RUN_CFG : show parsed run settings
  -S                 : a synonym for -t -D DUMP_VHOSTS -D DUMP_RUN_CFG
  -t -D DUMP_MODULES : show all loaded modules
  -M                 : a synonym for -t -D DUMP_MODULES
  -t -D DUMP_INCLUDES: show all included configuration files
  -t                 : run syntax check for config files
  -T                 : start without DocumentRoot(s) check
  -X                 : debug mode (only one worker, do not detach)

二、apache反向代理：

无法访问目标web时，使用目标web所在的网络内一台机器充当目标web的代理，客户端直接访问代理就像访问目标web一样.

三、操作步骤

1. 进入apache 配置文件所在目录：

cd /etc/apache2

2. 打开修改httpd.conf 文件

subl httpd.conf

//开启
LoadModule proxy_module libexec/apache2/mod_proxy.so
LoadModule proxy_connect_module libexec/apache2/mod_proxy_connect.so
LoadModule proxy_ftp_module libexec/apache2/mod_proxy_ftp.so
LoadModule proxy_http_module libexec/apache2/mod_proxy_http.so
LoadModule proxy_balancer_module libexec/apache2/mod_proxy_balancer.so

//新增

<VirtualHost *:80>
      ServerName test.ele.me   //目标web
      ProxyRequests off  
      Header set Access-Control-Allow-Origin *
      <Proxy *>
          Order deny,allow
          Allow from all
      </Proxy>
      <Location />
          ProxyPass http://127.0.0.1:4442/      
          ProxyPassReverse http://127.0.0.1:4442/   //需反向web
      </Location>
</VirtualHost>

3.重启生效

sudo apachectl -k restart
