连接 Apache 和 Tomcat

http://www.cnblogs.com/wpjsolo/archive/2012/01/19/2327457.html

http://httpd.apache.org/docs/current/zh-cn/vhosts/name-based.html

我的目标是: 用户访问 www.server.com 或 server.com 时, 由 Apache 处理请求, 当用户访问 tomcat.server.com 时, 由 Tomcat 处理请求.

一、设置 Apache 虚拟主机:

vim /etc/httpd/conf/httpd.conf

在 Group apache一句后面增加：

<VirtualHost *:80>
    # This first-listed virtual host is also the default for *:80
    ServerName www.server.com
    ServerAlias server.com
    DocumentRoot "/var/www/html"
</VirtualHost>

<VirtualHost *:80>
    ServerName tomcat.server.com
    ProxyPass / http://localhost:8080/
    ProxyPassReverse / http://localhost:8080/
</VirtualHost>

二、解决proxy引发的request.getServerName()问题

vim /opt/apache-tomcat-9.0.0.M8/conf/server.xml

将

<Connector port="8080" protocol="HTTP/1.1"
    connectionTimeout="20000"
    redirectPort="8443"
/>

改为:

<Connector port="8080" protocol="HTTP/1.1"
    connectionTimeout="20000"
    redirectPort="8443"
    proxyName="apache"
    proxyPort="80"
/>

三、重启服务

service httpd restart
service tomcat restart

四、配置模拟 DNS

参考模拟 DNS 一章, 增加记录:

192.168.19.222       www.server.com
192.168.19.222       tomcat.server.com

五、测试

访问 www.server.com 或 server.com 时, 看到的是 Apache 的欢迎页面, 访问 tomcat.server.com 时, 看到的是 Tomcat 的欢迎页面, 则说明配置成功.
