环境:前端nginx做分发(无PHP环境)，后端两台tomcat分别为：
nginx：192.168.3.89 www.tvvcd.com
tomcat1：192.168.3.73
tomcat2：192.168.3.78
一、前端Nginx配置
1.前端nginx安装必备的开发包
yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel
2.同步系统时间：
#vim /etc/ntp.conf //添加下面三行内容（19行下面添加）
server 3.cn.pool.ntp.org
server 3.asia.pool.ntp.org
server 0.asia.pool.ntp.org
# service ntpd stop
#ntpdate cn.pool.ntp.org //更新时间
#service ntpd start
#chkconfig ntpd on
3.安装pcre包和zlib以支持重写,正则以及网页压缩
pcre的安装
# unzip pcre-8.21.zip
# ./configure
# make && make install
4.Nginx的安装,给nginx安装jvmroute模块
# groupadd www
# useradd -g www -s /sbin/nologin www
# mkdir /usr/local/webserver/nginx/logs -p
# tar xvf nginx-upstream-jvm-route-0.1.tar.gz
# tar xvf nginx-1.0.11.tar.gz
# cd nginx-1.0.11
# patch -p0 < ../nginx_upstream_jvm_route/jvm_route.patch
# ./configure --prefix=/usr/local/webserver/nginx --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --user=www --group=www --with-http_ssl_module --with-http_stub_status_module --with-http_gzip_static_module --add-module=../nginx_upstream_jvm_route/
# make && make install
# vim /etc/nginx/nginx.conf

}
}
}
到/usr/bin目录下，把原用的java,javac文件删除:
# rm -rf /usr/bin/java
# rm -rf /usr/bin/javac
在/usr/bin 下建立 软连接 java
# ln -sv /usr/local/jdk1.6.0_29/bin/java /usr/bin/java
# ln -sv /usr/local/jdk1.6.0_29/bin/javac /usr/bin/javac
# java -version
java version "1.6.0_29"
Java(TM) SE Runtime Environment (build 1.6.0_29-b11)
Java HotSpot(TM) Client VM (build 20.4-b02, mixed mode, sharing)
# javac -version
javac 1.6.0_29
3.为了方便下在的工作建立两个软链接：
# ln -sv /usr/local/jdk1.6.0_29 /usr/local/jdk
# ln -sv /usr/local/jdk1.6.0_29/jre /usr/local/jre
4.Tomcat的安装
# tar xvf apache-tomcat-6.0.33.tar.gz
# mv apache-tomcat-6.0.33 /usr/local/tomcat
设置环境变量:
# vim ~/.bash_profile //仅当前用户有效
#Set Environment by NetSeek
JAVA_HOME=/usr/local/jdk
export JAVA_HOME
JRE_HOME=/usr/local/jre
export JRE_HOME
CLASSPATH=/usr=/usr/local/tomcat/common/lib/:/usr/local/jdk/lib:/usr/local/jre/lib
export CLASSPATH
PATH=$PATH:/usr/local/tomcat/bin/:/usr/local/jdk/bin:/usr/local/jre/bin
export PATH
TOMCAT_HOME=/usr/local/tomcat
export TOMCAT_HOME
# source ~/.bash_profile
5.启动tomcat以检查是否存在错误：
# cd /usr/local/tomcat/bin/
# ./startup.sh
http://IP地址:8080 可以看到猫头：）成功了。
在另一台机器上也安装tomcat 并配置好。
三、tomcat集群配置，session 同步配置：
1.tomca1 tomcat 2 在不同机器上
Tomcat 1 （IP: 192.168.3.73）
A、修改Engine节点信息： <Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat1">
B、去掉<Cluster> </Cluster> 的注释符
C、修改Cluster 节点信息
<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"
channelSendOptions="8">
<Manager className="org.apache.catalina.ha.session.DeltaManager"
expireSessionsOnShutdown="false"
notifyListenersOnReplication="true"/>
<Channel className="org.apache.catalina.tribes.group.GroupChannel">
<Membership className="org.apache.catalina.tribes.membership.McastService"
mcastBindAddress="192.168.3.73"
address="224.0.0.0"
port="45564"
frequency="500"
dropTime="3000"/>
<Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"
tcpListenAddress="192.168.3.73"
port="4001"
autoBind="100"
selectorTimeout="100"
maxThreads="6"/>
<Sender className="org.apache.catalina.tribes.transport.ReplicationTransmitter">
<Transport className="org.apache.catalina.tribes.transport.nio.PooledParallelSender"/>
</Sender>
<Interceptor className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/>
<Interceptor className="org.apache.catalina.tribes.group.interceptors.MessageDispatch15Interceptor"/>
</Channel>
<Valve className="org.apache.catalina.ha.tcp.ReplicationValve"
filter=""/>
<Valve className="org.apache.catalina.ha.session.JvmRouteBinderValve"/>
<Deployer className="org.apache.catalina.ha.deploy.FarmWarDeployer"
tempDir="/tmp/war-temp/"
deployDir="/tmp/war-deploy/"
watchDir="/tmp/war-listen/"
watchEnabled="false"/>
<ClusterListener className="org.apache.catalina.ha.session.JvmRouteSessionIDBinderListener"/>
<ClusterListener className="org.apache.catalina.ha.session.ClusterSessionListener"/>
</Cluster>
Tomcat 2 （IP: 192.168.3.78）
A、修改Engine节点信息： <Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat2">
B、去掉<Cluster> </Cluster> 的注释符
C、修改Cluster 节点信息（同上，只做小动修改即可）
修改web应用里面WEB-INF目录下的web.xml文件，加入标签
<distributable/>
直接加在</web-app>之前就可以了
四、测试 集群及session同步
在webapps 下新建test 目录
目录下建WEB-INF目录下的web.xml文件
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.5">
<display-name>TomcatDemo</display-name>
<distributable/>
</web-app>
新建test.jsp进行测试：
<%@ page contentType="text/html; charset=GBK" %>
<%@ page import="java.util.*" %>
<html><head><title>Cluster App Test</title></head>
<body>
Server Info:
<%
out.println(request.getLocalAddr() + " : " + request.getLocalPort()+"
");%>
<%
out.println("
ID " + session.getId()+"
");
String dataName = request.getParameter("dataName");
session.setAttribute("myname","session?");
if (dataName != null && dataName.length() > 0) {
String dataValue = request.getParameter("dataValue");
session.setAttribute(dataName, dataValue);
}
out.print("<b>Session P</b>");
Enumeration e = session.getAttributeNames();
while (e.hasMoreElements()) {
String name = (String)e.nextElement();
String value = session.getAttribute(name).toString();
out.println( name + " = " + value+"
");
System.out.println( name + " = " + value);
}
%>
<form action="test.jsp" method="OST">
name:<input type=text size=20 name="dataName">
key:<input type=text size=20 name="dataValue">
<input type=submit>
</form>
</body>
</html>
完成之后重启所有服务
到这里，已基本完成 |
