一、环境准备：
Apache服务器：redhat 6.5 192.168.75.128/192.168.85.128
TomcatA服务器：redhat 6.5 192.168.75.130
TomcatB服务器：redhat 6.5 192.168.75.131
Apache服务器安装httpd，安装方法参考：Linux编译安装Apache(httpd-2.4.18)
TomcatA、TomcatB安装Java和tomcat，安装方法参考:linux 安装tomcat
二、Apache服务器下载mod-jk
软件版本：tomcat-connectors-1.2.41-src.tar.gz 下载地址 http://tomcat.apache.org/download-connectors.cgi
# tar tomcat-connectors-1.2.41-src.tar.gz
# cd tomcat-connectors-1.2.41
# ./configure --with-apxs=/usr/local/apache/bin/apxs
# make && make install
# ll /usr/local/apache/modules/mod_jk.so
-rwxr-xr-x. 1 root root 1143306 Feb 3 18:04 /usr/local/apache/modules/mod_jk.so
LoadModule jk_module modules/mod_jk.so
JkWorkersFile /etc/httpd/extra/workers.properties
JkLogFile logs/mod_jk.log
JkLogLevel debug
JkMount /* TomcatA
JkMount /status/ stat1
worker.list=TomcatA,stat1
worker.TomcatA.port=8009
worker.TomcatA.host=192.168.75.130
worker.TomcatA.type=ajp13
worker.TomcatA.lbfactor=1
worker.stat1.type = status
vim /etc/httpd/httpd.conf
#DocumentRoot "/usr/local/apache/htdocs" #Include /etc/httpd/extra/httpd-proxy.conf Include /etc/httpd/extra/httpd-jk.conf
# cat /etc/httpd/extra/httpd-jk.conf # Load the mod_jk LoadModule jk_module modules/mod_jk.so JkWorkersFile /etc/httpd/extra/workers.properties JkLogFile logs/mod_jk.log JkLogLevel debug JkMount /* lbcluster JkMount /status/ stat1
# cat /etc/httpd/extra/workers.properties worker.list=lbcluster,stat1 worker.TomcatA.port=8009 worker.TomcatA.host=192.168.75.130 worker.TomcatA.type=ajp13 worker.TomcatA.lbfactor=1 worker.TomcatB.port=8009 worker.TomcatB.host=192.168.75.131 worker.TomcatB.type=ajp13 worker.TomcatB.lbfactor=1 worker.lbcluster.type=lb worker.lbcluster.balance_workers=TomcatA,TomcatB worker.lbcluster.sticky_session=0 worker.lbcluster.method=R worker.connection_pool_size=3000 worker.connection_pool_minsize=50 worker.connection_pool_timeout=50000 worker.stat1.type = status
注意：
worker.lbcluster.sticky_session=1 #如果要实现session绑定，则后端的tomcat一定要配置jvmRoute，而且jvmRoute和/etc/httpd/extra/workers.properties中的worker相同
tomcat配置：
