使用Apache配置Tomcat集群

q66262

1.下载jk--http://apache.mirror.phpchina.com/tomcat/tomcat-connectors/jk/binaries/win32/jk-1.2.26/mod_jk-1.2.26-httpd-2.2.4.so放到%APACHE_HOME%/modules/目录下
2.配置Apache httpd.conf
Include conf/mod_jk.conf
3.http.conf 同目录下新建mod_jk.conf文件
###########################################
#加载mod_jk Module
LoadModule jk_module modules/mod_jk-apache-2.0.55.so
#指定 workers.properties文件路径
JkWorkersFile conf/workers.properties
#指定那些请求交给tomcat处理,"controller"为在workers.propertise里指定的负载分配控制器
JkMount /*.* controller
###########################################
4.http.conf同目录下新建workers.peroperties文件
######################################################################
worker.list = controller
#========tomcat1========
worker.tomcat1.port=8010         #ajp13 端口号，在tomcat下server.xml配置,默认8009
worker.tomcat1.host=192.168.10.11    #tomcat的主机地址，如不为本机，请填写ip地址
worker.tomcat1.type=ajp13
worker.tomcat1.lbfactor = 1      #server的加权比重，值越高，分得的请求越多
#========tomcat2========
worker.tomcat2.port=8009       #ajp13 端口号，在tomcat下server.xml配置,默认8009
worker.tomcat2.host=192.168.10.173  #tomcat的主机地址，如不为本机，请填写ip地址
worker.tomcat2.type=ajp13
worker.tomcat2.lbfactor = 1    #server的加权比重，值越高，分得的请求越多
#========controller,负载均衡控制器========
worker.controller.type=lb
worker.controller.balance_workers=tomcat1,tomcat2   #指定分担请求的tomcat
worker.controller.sticky_session=1
######################################################################

5.负载均衡配置完成，还需要配置Session同步:
   在各台tomcat server上配置server.xml配置:
5.1将以下注释放开，并且修改jvmRoute为上述配置中对应的tomcat1,tomcat2,tomcat3....
<!-- You should set jvmRoute to support load-balancing via AJP ie :
<Engine name="Standalone" defaultHost="localhost" jvmRoute="jvm1">
-->

5.2将以下内容注释掉
<!-- Define the top level container in our container hierarchy -->
<Engine name="Catalina" defaultHost="localhost">

5.3将<Cluster> </Cluster> 注释放开即可,
重启tomcat,重启Apache
