1. 安装 Tomcat

apt-get install tomcat7
apt-get install tomcat7-admin
apt-get install tomcat7-docs
apt-get install tomcat7-examples

2. 开启，中止和重启

/etc/init.d/tomcat7 start
/etc/init.d/tomcat7 stop
/etc/init.d/tomcat7 restart

3. 根目录链接

cd /var/lib/tomcat7/webapps
sudo ln -s /usr/share/tomcat7-examples/examples examples
sudo ln -s /usr/share/tomcat7-docs/docs docs
sudo ln -s /usr/share/tomcat7-admin/manager manager
sudo ln -s /usr/share/tomcat7-admin/host-manager host-manager

4. JSP和PHP共存——Apache2反向代理实现

环境：ubuntu 12.04 + apache2 + tomcat
1.首先在tomcat中配置好jsp站点，映射端口8080
2.启用apache2的反向代理
apache2的配置文件都保存在/etc/apache2/中，启用反向代理既可以用a2enmod实现，也可以用ln手动设置
ln创建链接方式：

ln -s /etc/apache2/mods-available/proxy.load /etc/apache2/mods-enabled/proxy.load
ln -s /etc/apache2/mods-available/proxy.conf /etc/apache2/mods-enabled/proxy.conf
ln -s /etc/apache2/mods-available/proxy_http.load /etc/apache2/mods-enabled/proxy_http.load

a2enmod方式：

a2enmod proxy
a2enmod proxy_http

3.修改proxy.conf

vi /etc/apache2/mods-enabled/proxy.conf

配置为

<Proxy>
Order deny,allow
Allow from all
</Proxy>

4.修改apche2中的站点配置
apache2的站点配置默认保存在/etc/apache2/sites-enabled/文件夹中，默认是default
将站点localhost:80/8080映射到tomcat，文件配置如下：

<VirtualHost *:80>
ServerAdmin webmaster@localhostProxyRequests Off
<Location /8080>
ProxyPass http://localhost:8080/
ProxyPassReverse http://localhost:8080/
</Location>
#ProxyPass / http://localhost:8080/
#ProxyPassReverse / http://localhost:8080/DocumentRoot /var/www
<Directory />
Options FollowSymLinks
AllowOverride None
</Directory>
<Directory /var/www/>
Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
allow from all
</Directory>ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
<Directory "/usr/lib/cgi-bin">
AllowOverride None
Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
Order allow,deny
Allow from all
</Directory>ErrorLog ${APACHE_LOG_DIR}/error.log# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
LogLevel warnCustomLog ${APACHE_LOG_DIR}/access.log combinedAlias /doc/ "/usr/share/doc/"
<Directory "/usr/share/doc/">
Options Indexes MultiViews FollowSymLinks
AllowOverride None
Order deny,allow
Deny from all
Allow from 127.0.0.0/255.0.0.0 ::1/128
</Directory></VirtualHost>

5.重启apache2，测试
打开http://localhost/ 显示apache页面
打开http://localhost/8080 显示tomcat页面

如果有多个目录要映射，并且映射到不同站点的目录有父子关系的，要注意配置文件的顺序，如：

<Location /8080>
ProxyPass http://localhost:8080/
ProxyPassReverse http://localhost:8080/
</Location><Location />
ProxyPass http://website/
ProxyPassReverse http://website/
</Location>

使用Apache2反向代理不仅能让同一端口jsp和php共存，还能实现负载均衡等功能。

5. Apache、Tomcat、IIS（PHP、JSP、ASP）共存时的设置

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_connect_module modules/mod_proxy_connect.so
LoadModule proxy_http_module modules/mod_proxy_http.so

ProxyPass /jsp http://127.0.0.1:8080
#ProxyPassReverse /jsp http://127.0.0.1:8080ProxyPass /asp http://127.0.0.1:8081
#ProxyPassReverse http://127.0.0.1:8081
