tomcat session會話保持實驗-之Nginx+tomcat+memcachedcss

實驗要求html

一、nginx+tomcat 負載均衡java

二、memcached 會話保持node

memcached

下載以下jar文件至各tomcat節點的tomcat安裝目錄下的lib目錄中，其中的${version}要換成你所須要的版本號，tc${6,7,8}要換成與tomcat版本相同的版本號。

memcached-session-manager-${version}.jar

memcached-session-manager-tc${6,7,8}-${version}.jar

spymemcached-${version}.jar

msm-javolution-serializer-${version}.jar

javolution-${version}.jar

本實驗所用jar包已上傳（僅供實驗版本），各位能夠去下面連接下載：

http://down.51cto.com/3363989

或者到官方下載（這個應該被。。。）

memcached-session-manager項目地址，https://code.google.com/archive/p/memcached-session-manager/downloads

本實驗環境版本以下：

[root@node3~]# tomcat version

Server version: Apache Tomcat/7.0.69

Server built: Nov 6 201601:55:51 UTC

Server number: 7.0.69.0

OS Name: Linux

OS Version: 3.10.0-327.el7.x86_64

Architecture: amd64

JVM Version: 1.8.0_121-b13

JVM Vendor: OracleCorporation

安裝memcached

[root@node3~]# yum install memcached –y

[root@node4~]# yum install memcached -y

tomcat

ndoe3

一、[root@node3 ~]# vim /etc/tomcat/server.xml

分別在兩個tomcat上的某host上定義一個用於測試的context容器，並在其中建立一個會話管理器，以下所示：

<ManagerclassName="de.javakaffee.web.msm.MemcachedBackupSessionManager"

memcachedNodes="n1:172.16.100.9:11211,n2:172.16.100.10:11211"

failoverNodes="n1"

requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$" transcoderFactoryClass="de.javakaffee.web.msm.serializer.javolution.JavolutionTranscoderFactory"/>

</Context>

二、在<Engine name="Catalina"defaultHost="localhost"> 中添加jvmRoute="TomcatA"即

<Enginename="Catalina" defaultHost="localhost"jvmRoute="TomcatA">

#tomcatB主機則將此修改成tomcatB

node4：

一、將node3 tomcat配置文件server.xml拷貝一份至本機；

[root@node4~]# cd /etc/tomcat/

[root@node4 tomcat]# scp172.16.76.30:/etc/tomcat/server.xml .

二、注：修改 <Engine> 中jvmRoute=TomcatB；

重啓全部服務

[root@node2~]# systemctl restart nginx

[root@node3~]# systemctl restart tomcat
