1、创建虚拟主机（01-02）相同【192.168.200.121、192.168.200.122】
2、LB配置文件【192.168.200.120】
3、tomcat节点配置TomcatClusterRedisSessionManager方式实现redis共享（01-02）相同
4、安装redis、配置【192.168.200.123】
5、重启tomcat
6、测试访问，查看session不会再发生改变

[root@nginx ~]# wget https://github.com/ran-jit/tomcat-cluster-redis-session-manager/releases/download/4.0/tomcat-cluster-redis-session-manager.zip
## 解压
[root@nginx ~]# unzip tomcat-cluster-redis-session-manager.zip
## 拷贝jars到tomcat/lib目录中
[root@nginx ~]# cp tomcat-cluster-redis-session-manager/lib/* /soft/tomcat/lib/
## 拷贝配置文件到/conf中
[root@nginx ~]# cp tomcat-cluster-redis-session-manager/conf/redis-data-cache.properties /soft/tomcat/conf/
## 修改配置文件
[root@nginx ~]# grep "^[a-z]" /soft/tomcat/conf/redis-data-cache.properties
redis.hosts=192.168.200.123:6379
redis.cluster.enabled=false
redis.sentinel.enabled=false
redis.sentinel.master=mymaster
redis.timeout=2000
lb.sticky-session.enabled=false
session.persistent.policies=DEFAULT
redis.sso.timeout=0
## 修改context.conf中添加以下两行
[root@nginx ~]# vim /soft/tomcat/conf/context.xml
<Context>
.....
<Valve className="tomcat.request.session.redis.SessionHandlerValve" />
<Manager className="tomcat.request.session.redis.SessionManager" />
.....
</Context>
## 调整session的过期时间到60s，默认时30分钟，可以不用修改
[root@nginx ~]# vim /soft/tomcat/conf/web.xml
<session-config>
<session-timeout>30</session-timeout>
</session-config>安装redis、配置【192.168.200.123】
[root@redis ~]# yum -y install redis
[root@redis ~]# sed -i '/^bind/c bind 127.0.0.1 192.168.200.123' /etc/redis.conf
[root@redis ~]# systemctl restart redis
[root@redis ~]# netstat -lntp
