摘要: CentOS7 Redis+Tomcat集群实现session保持和共享

一、环境相关

操作系统：CentOS7

软件版本：nginx/1.9.15 Apache Tomcat/7.0.69 redis 3.20

网络环境：Nginx 192.168.5.250 Tomat1：192.168.5.251 Tomcat2：192.168.5.252 Redis：192.168.5.253

相关软件网盘地址：http://pan.baidu.com/s/1skBIlXV

二、相关软件配置

1、Nignx编译与添加自启脚本：http://my.oschina.net/huangweibin/blog/665239

Nginx 192.168.5.250

[root@nginx ~]# vim /etc/nginx/nginx.conf

http上下文
upstream tomcat {
server 192.168.5.251:8080;
server 192.168.5.252:8080;
}
server上下文
location / {
proxy_pass tomcat;
}

2、Reids编译与添加自启脚本：http://my.oschina.net/huangweibin/blog/671408

3、Tomcat编译与添加自启脚本：CentOS7 编译Tomcat并添加自启动脚本（注意：本文Tomcat要求版本为tomcat-7.x）

http://my.oschina.net/huangweibin/blog/668412

四、编译tomcat-redis-session-manager

1.官方下载地址 https://github.com/jcoleman/tomcat-redis-session-manager

2.配置编译环境Gradle：http://my.oschina.net/huangweibin/blog/671419

[root@localhost ~]# unzip tomcat-redis-session-manager-master.zip
[root@localhost ~]# cd tomcat-redis-session-manager-master/
[root@localhost tomcat-redis-session-manager-master]# vim build.gradle

注释以下内容：
//signing {
//  sign configurations.archives
//}
//repository(url: " https://oss.sonatype.org/service/local/staging/deploy/maven2/ ") {
// authentication(userName: sonatypeUsername, password: sonatypePassword)
//}

增加依赖包的输出脚本
task copyJars(type: Copy) {
from configurations.runtime
into 'dist'
}

3.执行gradle命令构建源码，编译输出tomcat-redis-session-manager-master 及依赖jar包（其他Tomcat只需要复制jar文件到tomcat目录）

[root@localhost tomcat-redis-session-manager-master]# gradle&nbs
3ff0
p;build -x test  copyJars
[root@localhost tomcat-redis-session-manager-master]# mkdir /tmp/jar
[root@localhost tomcat-redis-session-manager-master]# cp -a build/libs/*.jar /tmp/jar/ && cp -a dist/*.jar /tmp/jar/

[root@localhost jar]# ls /tmp/jar
commons-pool2-2.2.jar
jedis-2.5.2.jar
tomcat-annotations-api-7.0.27.jar
tomcat-api-7.0.27.jar
tomcat-catalina-7.0.27.jar
tomcat-juli-7.0.27.jar
tomcat-redis-session-manager-master-2.0.0.jar
tomcat-redis-session-manager-master-2.0.0-javadoc.jar
tomcat-redis-session-manager-master-2.0.0-sources.jar
tomcat-servlet-api-7.0.27.jar
tomcat-util-7.0.27.jar

[root@localhost jar]# cp -a /tmp/jar/* /usr/local/tomcat/lib/

五、配置Tomcat参数并创建测试页面（其他Tomcat配置类似）

[root@localhost jar]# vim /usr/local/tomcat/conf/context.xml

<Context>
<Valve className="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve" />
<Manager className="com.orangefunction.tomcat.redissessions.RedisSessionManager"
host="192.168.5.253"
port="6379"
database="0"
maxInactiveInterval="60" />
</Context>

[root@localhost jar]# mkdir -pv /usr/local/tomcat/webapps/session/WEB-INF/{classes,lib}

[root@localhost jar]# vim /usr/local/tomcat/webapps/session/index.jsp
<%@ page language="java" %>
<html>
<head><title>Tomcat1</title></head>
<body>
<h1><font color="red">Tomcat1.example.com</font></h1>
<table align="centre" border="1">
<tr>
<td>Session ID</td>
<% session.setAttribute("Tomcat.example.com","Tomcat.example.com"); %>
<td><%= session.getId() %></td>
</tr>
<tr>
<td>Created on</td>
<td><%= session.getCreationTime() %></td>
</tr>
</table>
</body>
</html>
