NAT集群部署solo之session server

author：JevonWei
版权声明：原创作品

使用Nginx做代理服务器，部署solo，使用session server做会话黏滞
拓扑图

环境

tomcatA    172.16.253.108
tomcatB    172.16.253.105
memcachedA 172.16.253.108
memcachedB 172.16.253.105
代理服务器 172.16.253.191

在Tomcat主机上搭建httpd服务，使httpd代理本机Tomcat应用,Nginx代理Tomcat

搭建Tomcat和Httpd服务器

TomcatA

[root@TomcatA ~]# yum -y install java-1.8.0-openjdk*
[root@TomcatA ~]# yum -y install tomcat-lib tomcat tomcat-webapps tomcat-docs-webapp tomcat-admin-webapps
[root@TomcatA ~]# iptables -F
[root@TomcatA ~]# setenforce  0
[root@TomcatA ~]# systemctl start tomcat

配置Tomcat测试页
[root@TomcatA ~]# mkdir /data/webapps/ROOT/{classes,lib,WEB-INF} -pv
[root@TomcatA ~]# vim /data/webapps/ROOT/index.jsp 
    <%@ page language="java" %>
    <html>
        <head><title>TomcatB</title></head>

安装后端memcached服务集群

程序下载 https://github.com/magro/memcached-session-manager/wiki/SetupAndConfiguration

下载相关程序到Tomcat主机的//usr/share/java/tomcat目录下

javolution-5.4.3.1.jar
memcached-session-manager-1.8.3.jar
memcached-session-manager-tc7-1.8.3.jar
msm-javolution-serializer-1.8.3.jar 
spymemcached-2.11.1.jar /usr/share/java/tomcat

memcachedA

[root@TomcatA ~]# yum -y install memcached
[root@TomcatA ~]# systemctl start memcached.service 
[root@TomcatA ~]# ss -ntl

memcachedB

[root@TomcatB ~]# yum -y install memcached
[root@TomcatB ~]# systemctl start memcached.service 
[root@TomcatB ~]# ss -ntl

配置Tomcat连接memcached服务端

TomcatA

[root@TomcatA ~]# vim /etc/tomcat/server.xml 
    <Engine name="Catalina" defaultHost="www.jevon1.com" jvmRoute="tcA">
     <Host name="www.jevon1.com"  appBase="/data/webapps"
        unpackWARs="true" autoDeploy="true">
        <Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"
            memcachedNodes="n1:172.16.253.108:11211,n2:172.16.253.105:11211"
            failoverNodes="n1"
            requestUriIgnorePattern=".*.(ico|png|gif|jpg|css|js)$"
            transcoderFactoryClass="de.javakaffee.web.msm.serializer.javolution.JavolutionTranscoderFactory"
        />
    </Host>
[root@TomcatB ~]# systemctl restart tomcat

TomcatB

[root@TomcatB ~]# vim /etc/tomcat/server.xml
    <Engine name="Catalina" defaultHost="localhost" jvmRoute="tcB">
    </Host>
   <Host name="localhost"  appBase="webapps"
        unpackWARs="true" autoDeploy="true">
    <Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"
        memcachedNodes="n1:172.16.253.108:11211,n2:172.16.253.105:11211"
        failoverNodes="n1"
        requestUriIgnorePattern=".*.(ico|png|gif|jpg|css|js)$"
        transcoderFactoryClass="de.javakaffee.web.msm.serializer.javolution.JavolutionTranscoderFactory"
      />
</Host>
[root@TomcatB ~]# systemctl restart tomcat

部署solo

[root@TomcatA ~]# vim /etc/tomcat/server.xml
<Engine name="Catalina" defaultHost="localhost" jvmRoute="tcA">
<Host name="localhost"  appBase="webapps"
        unpackWARs="true" autoDeploy="true">
 <Context path="/solo-2.2.0" docBase="solo-2.2.0" reloadable="true">
      <Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"
        memcachedNodes="n1:172.16.253.108:11211,n2:172.16.253.105:11211"
        failoverNodes="n1"
        requestUriIgnorePattern=".*.(ico|png|gif|jpg|css|js)$"
        transcoderFactoryClass="de.javakaffee.web.msm.serializer.javolution.JavolutionTranscoderFactory"
    />
</Context>
[root@TomcatA ~]# vim /etc/tomcat/tomcat-users.xml
<role rolename="manager-gui"/>  \启用manager-gui管理组
<user username="tomcat" password="tomcat" roles="manager-gui"/> \添加用户到manager-gui管理组中，用户为tomcat，密码为tomcat
[root@danran ~]# systemctl restart tomcat

浏览器http://172.16.253.105:8080/进入Manager App管理界面

选择solo应用的war文件部署

配置Tomcat的服务代理
[root@TomcatB webapps]# vim /etc/httpd/conf.d/tomcat.conf 
    <VirtualHost *:80>
        ServerName www.jevon2.com
        ProxyRequests Off
        ProxyVia On
        ProxyPreserveHost On
        <Proxy *>
            Require all granted
        </Proxy>
        ProxyPass / http://172.16.253.105:8080/solo-2.2.0/
        ProxyPassReverse / http://172.16.253.105:8080/solo-2.2.0/
        <Location />
            Require all granted
        </Location>
    </VirtualHost>
[root@TomcatB webapps]# systemctl restart httpd

修改solo的服务器配置文件
[root@TomcatB ~]# vim  /usr/share/tomcat/webapps/solo-2.2.0/WEB-INF/classes/latke.properties
    serverHost=172.16.253.105 \本机Tomcat的IP
[root@TomcatB ~]# systemctl restart tomcat
[root@TomcatB ~]# ss -ntl

TomcatB配置同TomcatA一致
