一、安装配置tomcat
配置前说明：
系统为centos7
m1.xsllqs.com地址为192.168.1.107
c1.xsllqs.com地址为192.168.1.114
c2.xsllqs.com地址为192.168.1.113
安装tomcat需要配合JDK使用，JDK有oracle JDK和open JDK两种
oracle JDK8的下载地址：http://www.oracle.com/technetwork/cn/java/javase/downloads/jdk8-downloads-2133151-zhs.html
tomcat的下载地址：http://tomcat.apache.org/
c1.xsllqs.com(192.168.1.114)下载安装jdk（建议加载到本地在传上去）和tomcat
[root@c1 ~]# wget http://download.oracle.com/otn-pub/java/jdk/8u73-b02/jdk-8u73-linux-x64.rpm
[root@c1 ~]# wget http://mirror.bit.edu.cn/apache/tomcat/tomcat-8/v8.0.36/bin/apache-tomcat-8.0.36.tar.gz
[root@c1 ~]# ls
apache-tomcat-8.0.36.tar.gz jdk-8u73-linux-x64.rpm
[root@c1 ~]# yum install jdk-8u73-linux-x64.rpm
[root@c1 ~]# vim /etc/profile.d/java.sh
export JAVA_HOME=/usr/java/latest
export PATH=$JAVA_HOME/bin:$PATH
[root@c1 ~]# . /etc/profile.d/java.sh
[root@c1 ~]# java -version
java version "1.8.0_73"
[root@c1 ~]# tar xf apache-tomcat-8.0.36.tar.gz -C /usr/local
[root@c1 ~]# cd /usr/local/
[root@c1 local]# ln -sv apache-tomcat-8.0.36 tomcat
"tomcat" -> "apache-tomcat-8.0.36"
[root@c1 tomcat]# vim /etc/profile.d/tomcat.sh
export CATALINA_HOME=/usr/local/tomcat
export PATH=$CATALINA_HOME/bin:$PATH
[root@c1 tomcat]# . /etc/profile.d/tomcat.sh
c2.xsllqs.com(192.168.1.113)下载安装jdk和tomcat
[root@c2 ~]# wget http://download.oracle.com/otn-pub/java/jdk/8u73-b02/jdk-8u73-linux-x64.rpm
[root@c2 ~]# wget http://mirror.bit.edu.cn/apache/tomcat/tomcat-8/v8.0.36/bin/apache-tomcat-8.0.36.tar.gz
[root@c2 ~]# ls
apache-tomcat-8.0.36.tar.gz jdk-8u73-linux-x64.rpm
[root@c2 ~]# yum install jdk-8u73-linux-x64.rpm
[root@c2 ~]# vim /etc/profile.d/java.sh
export JAVA_HOME=/usr/java/latest
export PATH=$JAVA_HOME/bin:$PATH
[root@c2 ~]# . /etc/profile.d/java.sh
[root@c2 ~]# java -version
java version "1.8.0_73"
[root@c2 ~]# tar xf apache-tomcat-8.0.36.tar.gz -C /usr/local
[root@c2 ~]# cd /usr/local/
[root@c2 local]# ln -sv apache-tomcat-8.0.36 tomcat
"tomcat" -> "apache-tomcat-8.0.36"
[root@c2 tomcat]# vim /etc/profile.d/tomcat.sh
export CATALINA_HOME=/usr/local/tomcat
export PATH=$CATALINA_HOME/bin:$PATH
[root@c2 tomcat]# . /etc/profile.d/tomcat.sh
二、修改tomcat配置文件
[root@c1 tomcat]# cd /usr/local/tomcat/webapps/
[root@c1 webapps]# mkdir myapp/{lib,classes,WEB-INF,META-INF} -pv
[root@c1 webapps]# cd myapp/
添加c1和c2的主页文件
[root@c1 myapp]# vim indix.jsp
<%@ page language="java" %>
<html>
<head><title>Tomcat1</title></head>
<body>
<h1><font color="red">c1.xsllqs.com</font></h1>
<table align="centre" border="1">
<tr>
<td>Session ID</td>
<% session.setAttribute("xsllqs.com","xsllqs.com"); %>
<td><%= session.getId() %></td>
</tr>
<tr>
<td>Created on</td>
<td><%= session.getCreationTime() %></td>
</tr>
</table>
</body>
</html>
[root@c2 myapp]# vim indix.jsp
<%@ page language="java" %>
<html>
<head><title>Tomcat2</title></head>
<body>
<h1><font color="blue">c2.xsllqs.com</font></h1>
<table align="centre" border="1">
<tr>
<td>Session ID</td>
<% session.setAttribute("xsllqs.com","xsllqs.com"); %>
<td><%= session.getId() %></td>
</tr>
<tr>
<td>Created on</td>
<td><%= session.getCreationTime() %></td>
</tr>
</table>
</body>
</html>
修改tomcat-user.xml（c1和c2都要改）
[root@c1 conf]# vim /usr/local/tomcat/conf/tomcat-users.xml
#在</tomcat-users>中添加
<role rolename="manager-gui"/>
<role rolename="admin-gui"/>
<user username="tomcat" password="<tomcat>" roles="manager-gui,admin-gui"/>
修改server.xml（c1和c2都要改）
[root@c1 conf]# vim /usr/local/tomcat/conf/server.xml
#修改主配置文件,appBase后面是应用的相对路径也可以是绝对路径
<Host name="localhost" appBase="webapps"
unpackWARs="true" autoDeploy="true">
#这里是访问日志的设置
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
prefix="localhost_access_log" suffix=".txt"
pattern="%h %l %u %t "%r" %s %b" />
#这里设置Context调用msm需要的组件，m1为主c2为备，因为我这里只有3台机器所以把c2作为备，正常情况是4台，2台memcached和2台tomcat
<Context path="/myapp" docBase="/usr/local/tomcat/webapps/myapp" reloadable="true">
<Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"
memcachedNodes="m1:192.168.1.107:11211,c2:192.168.1.113:11211"
failoverNodes="m1"
requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$"
transcoderFactoryClass="de.javakaffee.web.msm.serializer.javolution.JavolutionTranscoderFactory"
/>
</Context>
测试配置文件
[root@c1 ~]# catalina.sh configtest
[root@c2 ~]# catalina.sh configtest
[root@c1 ~]# catalina.sh start
[root@c2 ~]# catalina.sh start
三、安装msm
c1和c2上下载msm需要的jar包
[root@c1 ~]# wget http://repo1.maven.org/maven2/de/javakaffee/msm/memcached-session-manager/1.9.4/memcached-session-manager-1.9.4.jar
[root@c1 ~]# wget http://repo1.maven.org/maven2/de/javakaffee/msm/memcached-session-manager-tc8/1.9.4/memcached-session-manager-tc8-1.9.4.jar
[root@c1 ~]# wget http://repo1.maven.org/maven2/de/javakaffee/msm/msm-javolution-serializer/1.9.4/msm-javolution-serializer-1.9.4.jar
[root@c1 ~]# wget http://repo1.maven.org/maven2/net/spy/spymemcached/2.11.1/spymemcached-2.11.1.jar
[root@c1 ~]# wget http://www.java2s.com/Code/JarDownload/javolution/javolution-5.4.3.1.jar.zip
[root@c1 ~]# mv javolution-5.4.3.1.jar memcached-session-manager-1.9.4.jar memcached-session-manager-tc8-1.9.4.jar msm-javolution-serializer-1.9.4.jar spymemcached-2.11.1.jar /usr/local/tomcat/lib/
m1和c2上安装memcached
[root@m1 ~]# yum install memcached
[root@c2 ~]# yum install memcached
m1上安装nginx修改nginx的配置文件
[root@m1 ~]# yum install nginx
[root@m1 ~]# vim /etc/nginx/nginx.conf
#server外加入
upstream tcsrvs {
server 192.168.1.114:8080;
server 192.168.1.113:8080;
}
#server内加入
location ~* \.(jsp|do)$ {
proxy_pass http://tcsrvs;
}
[root@m1 ~]# nginx -t
启动服务
[root@m1 ~]# systemctl start nginx.service
[root@m1 ~]# systemctl start memcached
[root@c2 ~]# systemctl start memcached
