tomcat redis session共享

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'?>





<Context>



<WatchedResource>WEB-INF/web.xml</WatchedResource>









<Valve className="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve" />

<Manager className="com.orangefunction.tomcat.redissessions.RedisSessionManager"

host="10.0.0.51"

port="6379"

password='123'

database="0"

maxInactiveInterval="60" />

</Context>
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'?>
3. 
19. 
20. <Context>
22. 
23. <WatchedResource>WEB-INF/web.xml</WatchedResource>
25. 
26. 
30. 
32. 
35. <Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"
36. memcachedNodes="m1:192.168.2.37:11211,m2:192.168.2.27:11211"
37. failoverNodes="m2"
38. requestUriIgnorePattern=".*.(ico|png|gif|jpg|css|js)$"
39. transcoderFactoryClass="de.javakaffee.web.msm.serializer.javolution.JavolutionTranscoderFactory"/>
40. </Context>
41. 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
