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

安装后端memcached服务集群
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

[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
client测试访问
