Apache-2.2
通過 mod_proxy_ajp 的 Apache 反向代理不將請求路由到 Tomcat
我安裝了 Apache 和 Tomcat7 的兩個實例。一個在我的帶有 Mountain Lion 的 Macbook Pro 上，另一個在帶有 Ubuntu Server 12.10 的 Mac 上的 VirtualBox VM 上。兩者都具有相同的 VirtualHost 配置和 server.xml 配置。
在我的 Mac 上一切正常，但在 Ubuntu VM 上出現“文件不存在”錯誤。
當我將 LogLevel 設置為“調試”時，兩個日誌輸出看起來幾乎相同。
還有其他地方我可以查看為什麼請求沒有被代理到 Tomcat 嗎？
這是我的配置文件。

好吧，兩個想法。首先，在您的 Apache 配置中，為什麼您有 3 個 ProxyPass 設置用於似乎都設置為 live at 的 URL
/portal/？ProxyPass /portal/api-v1 ajp://127.0.0.1:8009/portal/api-v1 ProxyPassReverse /portal/api-v1 ajp://127.0.0.1:8009/portal/api-v1 ProxyPass /portal/jsp ajp://127.0.0.1:8009/portal/jsp ProxyPassReverse /portal/jsp ajp://127.0.0.1:8009/portal/jsp ProxyPass /portal/j_spring_security_check ajp://127.0.0.1:8009/portal/j_spring_security_check ProxyPassReverse /portal/j_spring_security_check ajp://127.0.0.1:8009/portal/j_spring_security_check如果可能的話，我建議將其簡化為以下內容：
ProxyPass /portal ajp://127.0.0.1:8009/portal/ ProxyPassReverse /portal ajp://127.0.0.1:8009/portal/我還添加了這一點
mod_rewrite以確保添加了斜杠：# Settings for adding a trailing slash to the URL RewriteEngine On RewriteCond %{REQUEST_URI} ^/(portal)$ RewriteRule ^(.*)$ http://%{HTTP_HOST}$1/ [R=301,L]另外，因為
mod_proxy我這樣做：# Proxy specific settings ProxyRequests Off ProxyPreserveHost On這將加起來像這樣的 Apache 虛擬主機配置。我還建議回滾
proxy.conf到您的預設值。將所有需要的設置放在 VirtualHost 文件中，如下所示，這樣您就不必做任何事情，但要確保配置文件在設置之間浮動，並且您不會將配置調整傳播到所有類型的文件：<VirtualHost *:80> DocumentRoot "/home/dbrogdon/development/app/application/portal/src/main/webapp/" ServerName ubuntu.dev ErrorLog ${APACHE_LOG_DIR}/ubuntu.dev.error.log CustomLog ${APACHE_LOG_DIR}/ubuntu.dev.access.log combined LogLevel debug ProxyPass /portal ajp://127.0.0.1:8009/portal/ ProxyPassReverse /portal ajp://127.0.0.1:8009/portal/ # Settings for adding a trailing slash to the URL RewriteEngine On RewriteCond %{REQUEST_URI} ^/(portal)$ RewriteRule ^(.*)$ http://%{HTTP_HOST}$1/ [R=301,L] # Settings for Apache Reverse Proxying <IfModule mod_proxy.c> # Proxy specific settings ProxyRequests Off ProxyPreserveHost On <Proxy *> AddDefaultCharset off Order deny,allow Allow from all </Proxy> ProxyPass /portal ajp://127.0.0.1:8009/portal/ ProxyPassReverse /portal ajp://127.0.0.1:8009/portal/ </IfModule> <Directory "/home/dbrogdon/development/app/application/portal/src/main/webapp/"> Options -Indexes FollowSymLinks AllowOverride AuthConfig FileInfo Order allow,deny Allow from all </Directory> </VirtualHost>在連接 Java Web 服務和 Apache 配置的世界時，這種設置對我來說總是很有效。
