篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Apache与tomcat整合方法相关的知识,希望对你有一定的参考价值。

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
