47_02Tomcat系列之apache负载均衡请求至tomcat及Deltamanager的使用

2015-10-31

#scp /etc/profile.d/{java.sh tomcat.sh } 192.168.10.9:/etc/profile.d/ 
#tar xf apache-tomcat-7.0.62.tar.gz -C /usr/local 
#cd /usr/local 
# ln -sv apache-tomcat-7.0.62/ tomcat 
#scp /usr/local/tomcat/conf/server.xml 192.168.10.9:/usr/local/tomcat/conf 
 
#vim /usr/local/tomcat/conf/server.xml 
改成： 
<Engine name="Cataina"> defaultHost="www.test.com" jvmRoute="Tomcat2"> 
 
#mkdir -pv /web/webapps 
#vim /web/webapps/index.jsp

基于mod_proxy实现负载均衡

在httpd.conf的虚拟主机中配置如下内容：

ProxyRequests Off 
<proxy balancer://lbcluster1> 
  BalancerMember ajp://192.168.10.8:8009 loadfactor=1 route=Tomcat1 
  BalancerMember ajp://192.168.10.9:8009 loadfactor=1 route=Tomcat2 
  ProxySet lbmethod=bytraffic 
</proxy> 
 
 
<VirtualHost *:80> 
  ServerName www.test.com 
  ProxyVia Off 
  ProxyPass / balancer://lbcluster1/  stickysession=jsessionid 
  ProxyPassReverse / balancer://lbcluster1/ 
    <Location /balancer-manager> 
      SetHandler balancer-manager 
      ProxyPass ! 
      Require all granted 
   </Location> 
<Proxy *> 
    Require all granted 
</Proxy> 
 <Location /> 
     Require all granted 
 </Location> 
</VirtualHost> 
 
 
# servive httpd restart

如果出错，看日志；；

172.16.100.106/balancer-manager

#vim /usr/local/tomcat/conf/server.xml 
 在Engine下面添加如下内容，要根据自己需要修改的；； 
    <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"   
             channelSendOptions="8">   
       
      <Manager className="org.apache.catalina.ha.session.DeltaManager"   
               expireSessionsOnShutdown="false"   
               notifyListenersOnReplication="true"/>   
       
      <Channel className="org.apache.catalina.tribes.group.GroupChannel">   
        <Membership className="org.apache.catalina.tribes.membership.McastService"   
                    address="228.50.10.1"   
                    bind="192.168.10.8"　　　//我在实验时如果加上这个出错； 
                    port="45564"   
                    frequency="500"   
                    dropTime="3000"/>   
        <Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"   
                  address="192.168.10.8"   
                  port="4000"   
                  autoBind="100"   
                  selectorTimeout="5000"   
                  maxThreads="6"/>   
       
        <Sender className="org.apache.catalina.tribes.transport.ReplicationTransmitter">   
          <Transport className="org.apache.catalina.tribes.transport.nio.PooledParallelSender"/>   
        </Sender>   
        <Interceptor className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/>   
        <Interceptor className="org.apache.catalina.tribes.group.interceptors.MessageDispatch15Interceptor"/>   
      </Channel>   
       
      <Valve className="org.apache.catalina.ha.tcp.ReplicationValve"   
             filter=""/>   
      <Valve className="org.apache.catalina.ha.session.JvmRouteBinderValve"/>   
       
      <Deployer className="org.apache.catalina.ha.deploy.FarmWarDeployer"   
                tempDir="/tmp/war-temp/"   
                deployDir="/tmp/war-deploy/"   
                watchDir="/tmp/war-listen/"   
                watchEnabled="false"/>   
       
      <ClusterListener className="org.apache.catalina.ha.session.JvmRouteSessionIDBinderListener"/>   
      <ClusterListener className="org.apache.catalina.ha.session.ClusterSessionListener"/>   
    </Cluster>

两台Tomcat主机：

# mkdir /web/webapps/WEB-INF 
# cp /usr/local/tomcat/conf/web.xml /web/webapps/WEB-INF/ 
# vim /web/webapps/WEB-INF/web.xml 

在=========Introduction===========上面添加： 
<distributable/> 

scp -r /web/webapps/WEB-INF/ 192.168.10.9:/web/webapps/
