【原创】ApacheTomcat集群在Linux下的搭建步骤

在RedHat5（以下简称RH）上搭建ApacheTomcat的集群环境，有以下步骤：

1.首先安装apr和apr-util

apr-util需要依赖于apr包，所以先安装apr，

http://files.cnblogs.com/zhangxsh/apr-util-1.5.3.tar.gz.rar

http://files.cnblogs.com/zhangxsh/apr-1.5.0.tar.gz.rar

2.安装pcre

http://files.cnblogs.com/zhangxsh/pcre-8.32.tar.gz.rar

3.安装httpd

http://files.cnblogs.com/zhangxsh/httpd-2.4.7.tar.gz.rar

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

[root@localhost httpd-2.4.7]# ./configure --prefix=/apache --with-apr-util=/usr/local/apr-util --with-pcre=/usr/local/pcre

[root@localhost httpd-2.4.7]#make

[root@localhost httpd-2.4.7]#make install

安装完后，还要安装jk:

http://files.cnblogs.com/zhangxsh/tomcat-connectors-1.2.37-src.tar.gz.rar

tomcat-connectors-1.2.37-src\tomcat-connectors-1.2.37-src\native\apache-2.0：

./configure --with

make

make install

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

====================================

1.配置apache/conf/httpd.conf，指定jk的配置路径以及负载均衡的tomcat的配置等等

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

LoadModule jk_module modules/mod_jk.so

JkWorkersFile conf/workers.properties

JkMountFile conf/uriworkermap.properties

JkLogFile logs/mod_jk.log

JkLogLevel warn

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

2.配置

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

[root@localhost conf]# vi workers.properties

 

#

# workers.properties

#

 

 

# list the workers by name

 

worker.list=DLOG4J, status --配置当前由哪些组件提供服务

 

--配置集群中有哪些tomcat组成，配置ajp协议的端口以及tomcat的ip地址

# localhost server 1

# ------------------------

worker.s1.port=8010

worker.s1.host=172.20.70.20

worker.s1.type=ajp13

 

# localhost server 2

# ------------------------

worker.s2.port=8011

worker.s2.host=172.20.70.20

worker.s2.type=ajp13

#worker.s2.stopped=1

 

------配置DLOG4J的工作方式为lb，也就是负载均衡

worker.DLOG4J.type=lb

worker.retries=3

--配置负载均衡下面有哪些tomcat做lb

worker.DLOG4J.balanced_workers=s1, s2

worker.DLOG4J.sticky_session=1

 

worker.status.type=status

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

===========================================

3.apachectl -k -start启动即可
