Windows环境Apache,Tomcat集群,动静分离,负载均衡

1.首先搭建Tomcat集群环境（多个tomcat共享session信息）

**下载分别解压tomcat8到tomcat1和tomcat2的两个文件夹中,得到以下目录**

![目录][20160212135544993]

修改server.xml文件内容。

<?xml version='1.0' encoding='utf-8'?>
    
    <Server port="8005" shutdown="SHUTDOWN">
      <Listener className="org.apache.catalina.startup.VersionLoggerListener" />
    
      <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
    
      <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
      <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
      <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />
    
    
      <GlobalNamingResources>
    
        <Resource name="UserDatabase" auth="Container" type="org.apache.catalina.UserDatabase" description="User database that can be updated and saved" factory="org.apache.catalina.users.MemoryUserDatabaseFactory" pathname="conf/tomcat-users.xml" />
      </GlobalNamingResources>
    
    
      <Service name="Catalina">
    
    
        <Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />
    
        <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
    
        <Engine name="Catalina" defaultHost="localhost" jvmRoute="jvm1" >
    
         <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>
    
    
          <Realm className="org.apache.catalina.realm.LockOutRealm">
    
            <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/>
          </Realm>
    
          <Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true">
    
    
            <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log" suffix=".txt" pattern="%h %l %u %t "%r" %s %b" />
    
          </Host>
        </Engine>
      </Service>
    </Server>

修改项目的web.xml文件

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
      <display-name>cluster</display-name>
      <welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.htm</welcome-file>
        <welcome-file>index.jsp</welcome-file>
        <welcome-file>default.html</welcome-file>
        <welcome-file>default.htm</welcome-file>
        <welcome-file>default.jsp</welcome-file>
      </welcome-file-list>
    
      <distributable/>
    </web-app>

**这样就完成了tomcat的简单集群搭建**

> 然后开始搭建apache对tomcat的动静分离,负载均衡

--------------------

1.下载apache安装包一路默认安装即可

2.修改httpd.conf配置文件,追加以下内容即可

LoadModule proxy_module modules/mod_proxy.so 
    LoadModule proxy_http_module modules/mod_proxy_http.so 
    LoadModule proxy_connect_module modules/mod_proxy_connect.so 
    LoadModule proxy_balancer_module modules/mod_proxy_balancer.so 
    
    
    
    
    ProxyPassMatch /*.gif$ ! 
    ProxyPassMatch /*.jpg$ !
    ProxyPassMatch /*.png$ ! 
    ProxyPassMatch /*.css$ ! 
    ProxyPassMatch /*.js$ ! 
    ProxyPassMatch /*.htm$ ! 
    ProxyPassMatch /*.html$ ! 
    
    ProxyPass / balancer://cluster/ 
    <Proxy balancer://cluster/>  
    BalancerMember http://127.0.0.1:8080/ loadfactor=1
    BalancerMember http://127.0.0.1:7080/ loadfactor=1 
    </Proxy>

3.配置静态资源

![这里写图片描述][20160212140859756]

静态资源在上面的htdocs目录配置即可。
