本文介绍Apache+tomcat+mod_jk负载均衡环境设置有条件转发,希望对于初学Apache服务器相关的朋友有帮助,更多Apache安装、配置、报错处理等资源请本站内搜索。

此玩意儿与lucene配合用.备忘之..

OS Centos5.2

需要的包:

httpd-2.2.3-11.el5_1.centos.3.i386.rpm

httpd-devel-2.2.3-11.el5_1.centos.3.i386.rpm

apache-tomcat-6.0.20.tar.gz

jdk-6u14-linux-i586-rpm.bin

tomcat-connectors-1.2.28-src.tar.gz

安装apache和jdk:

rpm -ivh httpd*  (httpd-devel依赖apr的包)  

./jdk-6u14-linux-i586-rpm.bin

加入环境变量:

vim /etc/profile

JAVA_HOME=/usr/java/jdk1.6.0_14

export JAVA_HOME

PATH=$PATH:/usr/java/jdk1.6.0_14/bin

export PATH

export CATALINA_HOME=/usr/local/tomcat

export TOMCAT_HOME=/usr/local/tomcat

source /etc/profile

安装配置tomcat:

tar xf apache-tomcat-6.0.20.tar.gz

mv apache-tomcat-6.0.20 /usr/local/tomcat

cp /usr/local/tomcat /usr/local/tomcat2

修改2个tomcat的配置文件。确保端口都不相同否则会冲突。否则只能起来一个。

vim /usr/local/tomcat/conf/server.xml

 <Connector port="8080" protocol="HTTP/1.1"

maxThreads="200"

connectionTimeout="20000"

redirectPort="8443" />

<Connector port="8109" protocol="AJP/1.3" redirectPort="8443" />

<Engine name="Catalina" defaultHost="localhost" jvmRoute="worker1">

vim /usr/local/tomcat2/conf/server.xml

<Server port="8106" shutdown="SHUTDOWN">

<Connector port="8088" protocol="HTTP/1.1"

maxThreads="200"

connectionTimeout="20000"

redirectPort="8443" />

<Connector port="8209" protocol="AJP/1.3" redirectPort="8443" />

<Engine name="Catalina" defaultHost="localhost" jvmRoute="worker2">

定制tomcat启动脚本:

tomcat1的脚本:

cat /usr/local/tomcat/bin/start.sh

#!/bin/bash

export CATALINA_HOME=/usr/local/tomcat

export TOMCAT_HOME=/usr/local/tomcat

./startup.sh

export CATALINA_HOME=/usr/local/tomcat2

export TOMCAT_HOME=/usr/local/tomcat2

cat /usr/local/tomcat/bin/stop.sh

#!/bin/bash

export CATALINA_HOME=/usr/local/tomcat

export TOMCAT_HOME=/usr/local/tomcat

./shutdown.sh

export CATALINA_HOME=/usr/local/tomcat2

export TOMCAT_HOME=/usr/local/tomcat2

tomcat2的脚本:

cat /usr/local/tomcat2/bin/start.sh

#!/bin/bash

export CATALINA_HOME=/usr/local/tomcat2

export TOMCAT_HOME=/usr/local/tomcat2

./startup.sh

export CATALINA_HOME=/usr/local/tomcat

export TOMCAT_HOME=/usr/local/tomcat

cat /usr/local/tomcat2/bin/stop.sh

#!/bin/bash

export CATALINA_HOME=/usr/local/tomcat2

export TOMCAT_HOME=/usr/local/tomcat2

./shutdown.sh

export CATALINA_HOME=/usr/local/tomcat

export TOMCAT_HOME=/usr/local/tomcat

安装mod_jk模块:(要装apr的包,也就是的httpd-xxx-devel所依赖的包)

tar xf tomcat-connectors-1.2.28-src.tar.gz

cd tomcat-connectors-1.2.28-src/native

./configure  --with-apxs=/usr/sbin/apxs --with-jni --with-apr-lib=/usr/lib

make&&make install

确保" /usr/lib/httpd/modules/mod_jk.so"存在且为755权限

在apache配置文件中加入模块的配置参数:

LoadModule jk_module modules/mod_jk.so

<IfModule mod_jk.c>

jkWorkersFile /etc/worker.properties

jkMountFile /etc/uriworkermap.properties

jkLogFile /var/log/mod_jk.log

jkLogLevel warn

jkShmFile /tmp/jk.shm

</IfModule>

在/etc下创建apache中模块参数中的配置文件于日志文件:

vim /etc/worker.properties (定义2个成员,注意:端口一定要和server.xml里相对应)

worker.list=worker1,worker2

worker.worker1.port=8109

worker.worker1.host=localhost

worker.worker1.type=ajp13

worker.worker2.type=ajp13

worker.worker2.port=8209

worker.worker2.host=localhost

vim /etc/uriworkermap.properties (定义uri请求的转发规则.)

/.*jsp=worker2

/hse/search=worker2

/hse/engine=worker1

/*.*=worker2

touch /var/log/mod_jk.log (不创建这个日志文件会导致apache起不来)

测试:

启动apache和tomcat.(确保2个tomcat能起来后再测试)

http://127.0.0.1:8080

http://127.0.0.1:8088

http://127.0.0.1    (apache的网站根目录与tomcat的目录指到一个,并注意权限)
