部署环境

主机	软件版本
192.168.88.1	nginx-1.12.2+redis-3.2.11
192.168.88.2	apache-tomcat-7.0.79 + jdk1.8
192.168.88.3	apache-tomcat-7.0.79 + jdk1.8

所需tomcat jar包，下载

commons-pool-1.5.4.jar

commons-pool2-2.4.1.jar

jedis-2.6.2.jar

tomcat-juli-adapters.jar

tomcat-juli.jar

tomcat-redis-session-manager1.2.jar

Tomcat配置

把tomcat jar包复制到$TOMCAT_BASE 下的lib目录

修改tomcat的配置文件conf/comtext.xml

#单点redis配置（我已经配置成功）
<Context>
<WatchedResource>WEB-INF/web.xml</WatchedResource>
<Valve className="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve" />
<Manager className="com.orangefunction.tomcat.redissessions.RedisSessionManager"
host="192.168.88.1"
port="6379"
database="0"
maxInactiveInterval="60"/>
</Context>

#基于redis集群配置（我还没测试）
<Context>
<WatchedResource>WEB-INF/web.xml</WatchedResource>
<Valve className="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve" />
<Manager className="com.orangefunction.tomcat.redissessions.RedisSessionManager"
maxInactiveInterval="60"
sentinelMaster="mymaster"
sentinels="127.0.0.1:26379,127.0.0.1:26380,127.0.0.1:26381"/>
</Context>

　　3、添加一个tomcat测试页index.jsp

# cat /opt/tomcat/webapps/ROOT/index.jsp
<html>
<head>
<title>nginx tomcat session test</title>
<meta name="Generator" content="EditPlus">
<meta name="Author" content="">
<meta name="Keywords" content="">
<meta name="Description" content="">
</head>

<h1>tomcat88.2</h1>    #这里192.168.88.3机器改为tomcat88.3
session: <%=session.getId()%>
</html>

　　4、启动tomcat

nginx配置

worker_processes  1;
events {
worker_connections  1024;
}
http {
include       mime.types;
default_type  application/octet-stream;
sendfile        on;
keepalive_timeout  65;

upstream tomcat {
server 192.168.88.2:8080 weight=1;
server 192.168.88.3:8080 weight=1;
}

server {
listen       80;
server_name  localhost;
location / {
proxy_pass http://tomcat; }
error_page   500 502 503 504  /50x.html;
location = /50x.html {
root   html;
}
}
}
