基于nginx1.9.10+tomcat8.0.30+spring4.2.2+shiro-redis搭建HA-CLUSTER

 tomcat配置（没啥配置，就配了个JVM,catalina.sh）

 

JAVA_OPTS="-Xms1g -Xmx1g -Xmn512m -XX:PermSize=256m -XX:MaxPermSize=512m -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:+UseCMSCompactAtFullCollection -XX:CMSFullGCsBeforeCompaction=0 -XX:CMSInitiatingOccupancyFraction=70"

 

shiro-redis配置(基于spring)

 

1、maven

<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-spring</artifactId>
    <version>1.2.4</version>
</dependency>

<dependency>
    <groupId>org.crazycake</groupId>
    <artifactId>shiro-redis</artifactId>
    <version>2.4.2.1-RELEASE</version>
</dependency>

 2、beans-shiro-redis.xml
