tomcat redis session共享

1. 编译redis所需要的序列化包

安装 gradle

Linux & MacOS users

Configure your PATH environment variable to include the bin directory of the unzipped distribution, e.g.:

$ export PATH=$PATH:/opt/gradle/gradle-5.3/bin

$ mkdir /opt/gradle

$ unzip -d /opt/gradle gradle-5.3-bin.zip

$ ls /opt/gradle/gradle-5.3

1. 拉源码包

git clone https://github.com/jcoleman/tomcat-redis-session-manager.git

1. 编译

[root@oldboy tomcat-redis-session-manager]# gradle build -x test copyJars

在tomcat-redis-session-manager/build/libs/目录下生成以下几个包

在tomcat-redis-session-manager/dist/下生成以下几个包

复制3个文件到tomcat/lib目录下

[root@oldboy dist]# cp jedis-2.5.2.jar tomcat-redis-session-manager-2.0.0.jar commons-pool2-2.6.0.jar /usr/local/tomcat/lib/

编写tomcat context.xml文件添加redis信息

[root@oldboy ~]# vim /usr/local/tomcat/conf/context.xml

<?xml version='1.0' encoding='utf-8'?>

1. 测试结果.随便刷新 seisson不变

1. 存到redis的session数据

1. jdk安装
   rpm -ivh jdk-8u151-linux-x64.rpm 
   如图：
   
   2、tomcat下载、解压
   tomcat 下载地址：http://tomcat.apache.org/
   tar xf apache-tomcat-7.0.78.tar.gz -C /usr/local/
   ln -s apache-tomcat-7.0.78 tomcat
   3、配置path环境变量
   vi /etc/profile.d/tomcat.sh
   export CATALINA_BASE=/usr/local/tomcat
   export PATH=$CATALINA_BASE/bin:$PATH 
   chmod +x /etc/profile.d/tomcat.sh # 赋予可执行权限
   source /etc/profile.d/tomcat.sh
   4、创建测试网页的发布目录
   mkdir /usr/local/tomcat/webapps/test/

[root@oldboy dist]# cat /usr/local/tomcat/webapps/test/index.jsp

<%@ page language="java" %>

<html>

<head><title>TomcatA</title></head>

<body>

<h1><font color="red">TomcatA.linuxinfo.top</font></h1>

<tablealign="centre" border="1">

<tr>

<td>SessionID</td>

<% session.setAttribute("linuxinfo.top","linuxinfo.top");%>

<td><%=session.getId() %></td>

</tr>

<tr>

<td>Createdon</td>

<td><%=session.getCreationTime() %></td>

</tr>

</table>

</body>

</html>

6、分别启动tomcat
catalina.sh start #可也用全路径/usr/local/tomcat/bin/startup.sh
7、访问192.168.2.197，测试如下，查看session ID

1下载五个jar包，将jar包放在/usr/local/tomcat/lib:

mgetjavolution-5.4.3.1.jar

memcached-session-manager-1.8.0jar

memcached-session-manager-tc7-1.8.0.jar

msm-javolution-serializer-1.8.0.jar

spymemcached-1.8.0.jar

1. 在contest.xml段定义一个用于测试的context容器，并在其中创建一个会话管理器。
   添加如下信息
   vim /usr/local/tomcat/conf/context.xml"
2. <?xml version='1.0' encoding='utf-8'?>

36. 重启服务：
    catalina.sh stop
    catalina.sh start
    3、下载memcached，启动服务
    yum install memcached -y
    systemctl start memcached
