apache+tomcat+mod_jk 集群安装说明

RedHat linux+apache+tomcat+mod_jk 集群安装说明

1. 操作系统

Red Hat Linux Enterprise 5

2. 所需软件

Apache 2.2.X；Tomcat5.5.9； Mod_jk 1.2.23 for apache 2.2.X； Jdk 1_5_0_04  

备注：下载时将所需软件包文件保存在/usr/local目录下

3. 安装步骤

A 安装JDK

# cd /usr/local/

# chmod +x jdk-1_5_0_04-linux-i586-rpm.bin

# ./jdk-1.5.0_04-linux-i586-rpm.bin

# cd /usr/java/

# ln -s /usr/java/jdk-1_5_0_04 /usr/local/java

# vi /etc/profile

  #添加如下内容

JAVA_HOME=/usr/local/java/

CLASSPATH=/usr/local/java/lib/dt.jar:/usr/local/java/lib/tools.jar

PATH=/usr/local/java/bin:$PATH

export PATH JAVA_HOME CLASSPATH

B 安装Apache

# cd /usr/local/

# tar xvfz httpd-2.0.54.tar.gz

# cd httpd-2.0.54

#./configure --prefix=/usr/local/apache2 --enable-so --enable-mods-shared=most

--enable-so相当与1.3.27的--enable-module=so，而--enable-mods-shared=most又等同与以前的--enable-shared=max 这些区别大家要注意了

# make

# make install

# cd /usr/local/apache/conf

# vi ./httpd.conf

将Listen 80 修改为Listen :80

将ServerName 修改为ServerName :80

在DirectoryIndex中添加 index.jsp

  # cd /usr/local/apache/bin/

# ./apachectl configtest

若显示Syntax ok则表明安装成功

#./apachectl start

启动apache服务，访问本机80端口，查看端口是否正常

# ./apachectl stop

关闭服务

备注：prefix定义apache的安装路径

C安装Tomcat

  # cd /usr/local/

  # tar xvfz jakarta-tomcat-5.5.9.tar.gz

  # ln –s /usr/local/jakarta-tomcat-5.5.9　/usr/local/tomcat

  # vi /usr/local/tomcat/bin/catalina.sh

      JAVA_HOME=/usr/local/java

 启动服务后，访问本机8080端口，查看端口是否正常

# /usr/local/tomcat/bin/startup.sh /startup.bat

  关闭服务

# /usr/local/tomcat/bin/shutdown.sh /shutdown.bat

D 安装JK

#cd /usr/local/

# tar xzvf jakarta-tomcat-connectors-1.2.14-src.tar.gz

#cd jakarta-tomcat-connectors-1.2.14-src/jk/native

#chmod 755 buildconf.sh

#./buildconf.sh

#./configure --with-apxs=/usr/local/apache/bin/apxs

#make

#make install

#cd /usr/local/ jakarta-tomcat-connectors- jk1.2.14-src/jk/native/apache-2.0/

#cp mod_jk.so /usr/local/apache/modules/

E 系统整合

1．修改Apache httpd.conf 文件

#vi /usr/local/apache/conf/httpd.conf

在文件最末尾加上如下语句

# Load mod_jk
LoadModule jk_module modules/mod_jk.so
# Configure mod_jk
JkWorkersFile conf/workers.properties
JkLogFile logs/mod_jk.log
JkLogLevel info

JkMount /*.* loadbalancer

JkMount /*.jsp loadbalancer

JkMount /*.html loadbalancer

JkMount /*.do loadbalancer
JkMount /servlet/* loadbalancer
JkMount /application/* loadbalancer

2．为apache创建work.properties

#vi /usr/local/apache/conf/workers.properties
#
# workers.properties
#
# In Unix, we use forward slashes:

ps=/

# list the workers by name
worker.list=tomcat1, tomcat2, loadbalancer
# ------------------------
# First tomcat server
# ------------------------

worker.tomcat1.port=8009
worker.tomcat1.host=192.168.1.33

worker.tomcat1.type=ajp13
# Specify the size of the open connection cache.
#worker.tomcat1.cachesize
#
# Specifies the load balance factor when used with
# a load balancing worker.
# Note:
# ----> lbfactor must be > 0
# ----> Low lbfactor means less work done by the worker.
worker.tomcat1.lbfactor=100

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

# Second tomcat server

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

worker.tomcat2.port=8009
worker.tomcat2.host=192.168.1.34
worker.tomcat2.type=ajp13
# Specify the size of the open connection cache.
#worker.tomcat2.cachesize
#
# Specifies the load balance factor when used with
# a load balancing worker.
# Note:
# ----> lbfactor must be > 0
# ----> Low lbfactor means less work done by the worker.
worker.tomcat2.lbfactor=100
# ------------------------
# Load Balancer worker
# ------------------------
# The loadbalancer (type lb) worker performs weighted round-robin
# load balancing with sticky sessions.
# Note:
# ----> If a worker dies, the load balancer will check its state
# once in a while. Until then all work is redirected to peer
# worker.
worker.loadbalancer.type=lb
worker.loadbalancer.balanced_workers=tomcat1, tomcat2
#
# END workers.properties
#

3.修改Tomcat server.xml

#vi /usr/local/tomcat/conf/server.xml

3.1 <Connector　port="8009" 
protocolHandlerClassName="org.apache.jk.server.JkCoyoteHandler"  
redirectPort="8443" protocol="AJP/1.3" />

3.2 在120行左右加入如下语句

<Engine name="Standalone" defaultHost="localhost"

jvmRoute="tomcat1"></Engine>
若第二台tomcat，将jvmRoute的修改为tomcat2

         3.3  去掉<Cluster className="org.apache.catalina.cluster.tcp.SimpleTcpCluster"

                 managerClassName="org.apache.catalina.cluster.session.DeltaManager"

                 expireSessionsOnShutdown="false"

                 useDirtyFlag="true"

                 notifyListenersOnReplication="true">部分的注释

         3 .4 在工程的web.xml里加入   

                   <display-name>Nokia CCMS</display-name>

                  <distributable/>

4. 启动apache和tomcat服务

# /usr/local/apache/bin/apachectl start
#/usr/local/tomcat/bin/catalina.sh start
将如下内容添加至/etc/rc.d/rc.local文件末尾，以便系统启动后开启apache,tomcat服务
/usr/local/tomcat/bin/catalina.sh start
/usr/local/apache/bin/apachectl start
