2.1.4. 防火墙配置

iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT

80 跳转 8080 方案

iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080

取消跳转

iptables -t nat -D PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080

查看规则

iptables -t nat -L

例 2.4. tomcat firewall

下面是完整的例子，仅供参考，复制到 /etc/sysconfig/iptables 文件中，重启iptables即可生效。

2.1.5. 同时运行多实例

创建工作目录

mkdir /srv/apache-tomcat

每个端口一个目录

tar zxvf apache-tomcat-7.0.x.tar.gz
mv  apache-tomcat-7.0.x /srv/apache-tomcat/8080

tar zxvf apache-tomcat-7.0.x.tar.gz
mv  apache-tomcat-7.0.x /srv/apache-tomcat/9090

修改 Server port="8006" 与 Connector port="9090"端口，不要出现重复。

		

<Server port="8006" shutdown="SHUTDOWN">


 <Connector port="9090" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

<!--
    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
-->

启动tomcat然后观察catalina.log日志文件，确认每个进程都正确启动。

2.1.6. Testing file

创建测试文件

vim webapps/ROOT/index.jsp

		
<%@ page contentType="text/html;charset=utf-8"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>helloworld!</title>
</head>

<body>
<h1>
<%="It works!"%>
</h1>
<%
out.println("<h3>Hello World!</h3>");
%>
<hr />
<%=new java.util.Date()%>
</body>
</html>

使用curl命令测试，测试结果类似下面结果。

		
$ curl http://192.168.6.9/index.jsp

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>helloworld!</title>
</head>

<body>
<h1>
It works!
</h1>
<h3>Hello World!</h3>

<hr />
Mon Jul 22 16:41:46 HKT 2013
</body>
</html>

2.1.7. mod_jk

mod_jk 安装

tar zxvf tomcat-connectors-1.2.23-src.tar.gz
cd tomcat-connectors-1.2.23-src/native/
./configure --with-apxs=/usr/local/apache/bin/apxs
make
make install
chmod 755 /usr/local/apache/modules/mod_jk.so

</IfModule>

分别测试apache,tomcat

2.1.8. mod_proxy_ajp

包含虚拟主机配置文件

# vi conf/httpd.conf

# Virtual hosts
Include conf/extra/httpd-vhosts.conf

虚拟主机中配置ProxyPass,ProxyPassReverse

# vi conf/extra/httpd-vhosts.conf

		
<VirtualHost *:80>
    ServerName netkiller.8800.org
    ProxyPass /images !
	ProxyPass /css !
	ProxyPass /js !
    ProxyPass /ajp ajp://localhost:8009/ajp
    ProxyPassReverse /ajp ajp://localhost:8009/ajp
</VirtualHost>

反向代理和均衡负载模块

		
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
LoadModule proxy_balancer_module modules/mod_proxy_balancer.so

ProxyPass /admin balancer://tomcatcluster/admin lbmethod=byrequests stickysession=JSESSIONID nofailover=Off timeout=5 maxattempts=3
ProxyPassReverse /admin balancer://tomcatcluster/admin

<Proxy balancer://tomcatcluster>
	BalancerMember ajp://localhost:8009 route=web1
	BalancerMember ajp://localhost:10009 smax=10 route=web2
	BalancerMember ajp://localhost:11009 route=web3
	BalancerMember ajp://localhost:12009 smax=10 route=web4
</Proxy>

2.1.9. RewriteEngine 连接 Tomcat

		
RewriteEngine On

RewriteRule ^/(.*) ajp://localhost:8009/ajp/$1 [P]
RewriteRule ^/(.*\.(jsp|do|sevlet)) ajp://localhost:8009/ajp/$1 [P]

2.1.10. SSL 双向认证

首先我并不建议使用 tomcat 实现SSL双向验证，这个工作可以交给 Web 服务器完成。但有些场景可能需要，可以参考下面例子。

服务器端证书

keytool -genkey -v -alias serverKey -dname "CN=localhost" -keyalg RSA -keypass xxxxxx -keystore server.ks -storepass xxxxxx

客户端证书

keytool -genkey -v -alias clientKey -dname "CN=SomeOne" -keyalg RSA -keypass xxxxxx -keystore client.p12 -storepass xxxxxx -storetype PKCS12		
keytool -export -alias clientKey -file clientKey.cer -keystore client.p12 -storepass xxxxxx -storetype PKCS12

导入客户端证书

keytool -import -v -alias clientKey -file clientKey.cer -keystore server.ks -storepass xxxxxx

如果希望在 Windows 浏览器中访问，下导入证书方式，双击 client.p12 文件，安装提示导入

配置 Tomcat ，编辑 server.xml 文件

		
<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"
maxThreads="1024" scheme="https" secure="true"
clientAuth="true" sslProtocol="TLS"
keystoreFile="server.ks" keystorePass="xxxxxx"
truststoreFile="server.ks " truststorePass="xxxxxx" />
