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" %>
    
        
            
            
TomcatB.magedu.com
            
                <% session.setAttribute("magedu.com","magedu.com"); %>
                    

                

                    
Session ID
<%= session.getId() %>

[root@nginx ~]# nginx -t
[root@nginx ~]# systemctl start nginx

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 
    
     
        
    
[root@TomcatB ~]# systemctl restart tomcat

TomcatB

[root@TomcatB ~]# vim /etc/tomcat/server.xml
    
    
   
    

[root@TomcatB ~]# systemctl restart tomcat

部署solo

[root@TomcatA ~]# vim /etc/tomcat/server.xml


 
      

[root@TomcatA ~]# vim /etc/tomcat/tomcat-users.xml
  \\启用manager-gui管理组
 \\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 
    
        ServerName www.jevon2.com
        ProxyRequests Off
        ProxyVia On
        ProxyPreserveHost On
        
            Require all granted
        
        ProxyPass / http://172.16.253.105:8080/solo-2.2.0/
        ProxyPassReverse / http://172.16.253.105:8080/solo-2.2.0/
        
            Require all granted
        
    
[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
