Apache中有一個mod_proxy模組，開啟後就可以讓Apache有proxy的功能(很吃記憶體)
最常用到的就是用在網頁上
Enable
如果在Ubuntu中可以透過以下指令開啟
1 | a2enmod proxy_http |
在FreeBSD中必須手動開啟以下兩個Module
1 | LoadModule proxy_module libexec/apache22/mod_proxy.so |
2 | LoadModule proxy_http_module libexec/apache22/mod_proxy_http.so |
Forward Proxy
Forward Proxy是一般proxy的代理功能
1 | Listen 8080 |
2 | <VirtualHost *:8080> |
3 | ServerName proxy.johnsonlu.org |
4 | #ProxyRequests要開啟，啟動Forward功能 |
5 | ProxyRequests On |
6 | ProxyVia On |
7 |
8 | <Proxy *> |
9 | Order deny,allow |
10 | Deny from all |
11 | Allow from all |
12 | </Proxy> |
13 |
14 | ErrorLog "/var/log/apache2/proxy-error.log" |
15 | CustomLog "/var/log/apache2/proxy-access.log" common |
16 | </VirtualHost> |
Reverse Proxy
Reverse Proxy跟Forward Proxy正好相反，可以應用在導向內部實際服務的伺服器
1 | <VirtualHost *:80> |
2 | ServerName blog.johnsonlu.org |
3 | #因為只是Reverse，因此ProxyRequests要關閉 |
4 | ProxyRequests off |
5 | <Proxy *> |
6 | Order allow,deny |
7 | Allow from all |
8 | </Proxy> |
9 |
10 | ProxyPass / http://localhost:3000/ |
11 | ProxyPassReverse / http://localhost:3000/ |
12 | ProxyPreserveHost on |
13 | </VirtualHost> |
