题记：这个以前其实做过好多次了，但可惜的是一直都没有做记录，现在隔了蛮长时间了，好多东西都又不记得了。
环境：CentOS 5.1，无SELinux，无iptables
安装的软件：
- httpd，httpd-devel
- jdk-6u6-linux-i586.bin
- apache-tomcat-6.0.16.tar.gz
- tomcat-connectors-1.2.26-src.tar.gz（即jk_mod）
一，安装httpd，httpd-devel
[root@server ~]# yum install -y httpd httpd-devel
二，安装JDK
[root@server ~]# chmod u+x jdk-6u6-linux-i586.bin
[root@server ~]# ./jdk-6u6-linux-i586.bin
[root@server ~]#export JAVA_HOME=/root/jdk1.6.0_06
[root@server ~]#export PATH=$PATH:${JAVA_HOME}/bin
[root@server ~]# ./jdk-6u6-linux-i586.bin
[root@server ~]#export JAVA_HOME=/root/jdk1.6.0_06
[root@server ~]#export PATH=$PATH:${JAVA_HOME}/bin
三，安装jk_mod
[root@server ~]# tarp -xvf tomcat-connectors-1.2.26-src.tar.gz
[root@server ~]# cd tomcat-connectors-1.2.26-src
[root@server tomcat-connectors-1.2.26-src]# cd native/
[root@server native]# ./configure --with-apxs=/usr/sbin/apxs
[root@server native]# make
[root@server native]# make install
[root@server ~]# cd tomcat-connectors-1.2.26-src
[root@server tomcat-connectors-1.2.26-src]# cd native/
[root@server native]# ./configure --with-apxs=/usr/sbin/apxs
[root@server native]# make
[root@server native]# make install
四，安装配置tomcat
安装tomcat
这个非常简单，我们只要将apache-tomcat-6.0.16.tar.gz解压就可以了，因为我们要做负载均衡，所以我们加上两个tomcat
[root@server ~]# tar -xvf apache-tomcat-6.0.16.tar.gz
[root@server ~]# mv apache-tomcat-6.0.16 tomcat1
[root@server ~]# cp -r tomcat1 tomcat2
[root@server ~]# mv apache-tomcat-6.0.16 tomcat1
[root@server ~]# cp -r tomcat1 tomcat2
配置tomcat
这步要配置的东西也不多，主要是server.xml里面的四个参数：Server port, AJP port, http port以及 jvmRoute
/root/tomcat1/的参数：
Server port: 6001
AJP port: 7001
http port: 8001
jvmRoute: tomcat1
AJP port: 7001
http port: 8001
jvmRoute: tomcat1
/root/tomcat2/的参数：
Server port: 6002
AJP port: 7002
http port: 8002
jvmRoute: tomcat2
AJP port: 7002
http port: 8002
jvmRoute: tomcat2
五，配置apache
创建workers.properties文件
[root@server conf]# pwd
/etc/httpd/conf
[root@server conf]# touch workers.properties
/etc/httpd/conf
[root@server conf]# touch workers.properties
文件内容如下：
ps=/
#The advanced router LB worker and jk_status
worker.list=router,status
# Define a worker using ajp13
worker.tomcat1.port=7001
worker.tomcat1.host=localhost
worker.tomcat1.type=ajp13
worker.tomcat1.lbfactor=1
#Define another worker using ajp13
worker.tomcat2.port=7002
worker.tomcat2.host=localhost
worker.tomcat2.type=ajp13
worker.tomcat2.lbfactor=1
#Define the LB worker
worker.router.type=lb
worker.router.balance_workers=tomcat1,tomcat2
worker.router.sticky_session=1
worker.status.type=status
#The advanced router LB worker and jk_status
worker.list=router,status
# Define a worker using ajp13
worker.tomcat1.port=7001
worker.tomcat1.host=localhost
worker.tomcat1.type=ajp13
worker.tomcat1.lbfactor=1
#Define another worker using ajp13
worker.tomcat2.port=7002
worker.tomcat2.host=localhost
worker.tomcat2.type=ajp13
worker.tomcat2.lbfactor=1
#Define the LB worker
worker.router.type=lb
worker.router.balance_workers=tomcat1,tomcat2
worker.router.sticky_session=1
worker.status.type=status
编辑http.conf
找到：
LoadModule version_module modules/mod_version.so
在下面添加：
LoadModule jk_module modules/mod_jk.so
JkWorkersFile conf/workers.properties
JkWorkersFile conf/workers.properties
找到：
DocumentRoot "/var/www/html"
在下面添加：
JkMount /* router
JkLogFile /var/log/httpd/mod_jk.log
JkLogLevel debug
JkLogStampFormat "[%a %b %d %U %H:%M:%S %w %R %Y] "
JkLogFile /var/log/httpd/mod_jk.log
JkLogLevel debug
JkLogStampFormat "[%a %b %d %U %H:%M:%S %w %R %Y] "
六，启动所有程序
[root@server ~]# /etc/init.d/httpd start
[root@server ~]# /root/tomcat1/bin/startup.sh
[root@server ~]# /root/tomcat2/bin/startup.sh
[root@server ~]# /root/tomcat1/bin/startup.sh
[root@server ~]# /root/tomcat2/bin/startup.sh
到这里，我们输入http://localhost
就已经可以看到tomcat的页面了，loadbalance已经配置成功了
大家可以做些实验测试下，我就不再继续了
