【问题描述】：

我已将 apache 配置为将请求转发给 tomcat。以下是我的配置。

<VirtualHost *:80>

ServerName ***
ServerAlias ***
ServerAlias ***


RewriteEngine on
RewriteCond %HTTP_HOST =***
RewriteRule (.*) https://***/ [R]
RewriteCond %HTTP_HOST =***
RewriteRule (.*) https://***/ [R]
RewriteCond %HTTP_HOST =***
RewriteRule (.*) https://***/ [R]


</VirtualHost>

<VirtualHost *:443>

ServerName ***
ServerAlias ***
ServerAlias ***

ProxyPass / ajp://localhost:8009/
ProxyPassReverse / ajp://localhost:8009/


SSLEngine on
SSLCertificateFile /etc/pki/tls/certs/***.com.crt
SSLCertificateKeyFile /etc/pki/tls/private/***.key
SSLCACertificateFile /etc/pki/tls/certs/***.crt

</VirtualHost>

我在 apache 日志中收到以下错误

[Sun Feb 26 23:28:28 2012] [error] (111)Connection refused: proxy: AJP: attempt to connect to 127.0.0.1:8009 (localhost) failed

[Sun Feb 26 23:28:29 2012] [error] proxy: AJP: disabled connection for (localhost)

它工作了一段时间然后突然我收到以下错误

Service Temporarily Unavailable

The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

当我尝试netstat -antup | grep 8009 命令时，我得到了以下信息

tcp        1      0 ::1:40293                   ::1:8009                    CLOSE_WAIT  32434/httpd

我不知道我的问题出在哪里。是apache配置还是tomcat配置还是编码问题……我相信是配置问题……请帮帮我..

【问题讨论】：

你的tomcat配置监听的端口是什么？

我的 tomcat 配置为 SSL 的 8080 和 8443，我也有 ajp ''

【参考方案1】：

修复后我遇到了两个问题 tomcat 没有崩溃..

在 Hardisk 中有坏扇区。我在消息日志中发现所以 java 崩溃了。。 我让旧的石英调度程序运行..我删除了，然后现在 tomcat 没有崩溃..
