Nginx+tomcat+memcached-session-manager compose a simple cluster

1. Build the Environment

192.168.29.128 (luxh-01.com) installation Nginx, reference http://www.cnblogs.com/luxh/p/4067038.html

192.168.29.129 (luxh-02.com) installs Tomcat and memcached

192.168.29.130 (luxh-03.com) installs Tomcat and memcached

2, installation memcached

1) install directly with Yum

[Email protected]yuminstall memcached

2) Start memcached, the default boot port is 11211

[Email protected] ~]# memcached-u memcached

-U Specify user

3) test whether the start is successful

[Email protected]127.0. 0.1 11211

3, Installation Tomcat7

Reference: http://www.cnblogs.com/luxh/p/3188736.html

4. Add Memcached-session-manager related jar to Tomcat

Place the following jar in the Lib directory of the Tomcat installation path

memcached-session-manager-1.8.2. jarmemcached-session-manager-tc7-1.8.2. jarspymemcached- 2.11.1.jar

Note that the version of Tomcat is different, the jar version is also different, specifically refer to Http://code.google.com/p/memcached-session-manager/wiki/SetupAndConfiguration

5. Add serializers related jars to the web App

The serialization is implemented here using Kryo-serializer.

The project uses MAVEN to add dependencies directly

<dependency>    <groupId>de.javakaffee.msm</groupId>    <artifactId> msm-kryo-serializer</artifactid>    <version>1.8.0</version>    <scope> Runtime</scope></dependency>

If you do not use MAVEN, add the following jar to the project yourself

msm-kryo-serializer-1.8.0. jarkryo-serializers-0.11. jarkryo-1.04.jarasm-3.2. jarreflectasm-1.01. jarminlog-1.2.jarjsr305-1.3.9. jarannotations-1.3.9. Jar

6. Configuring Memcached-session-manager in Tomcat

Include the following in the Tomcat context.xml file (<Context></Context> tag).

Non-sticky session configuration, two memcached servers.

<className= "De.javakaffee.web.msm.MemcachedBackupSessionManager"     Memcachednodes= "n1:luxh-02.com:11211,n2:luxh-03.com:11211"    sticky= "false"     sessionbackupasync= "false"    requesturiignorepattern= ". *\. ( ICO|PNG|GIF|JPG|CSS|JS) $ "    transcoderfactoryclass=" De.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory "    />

7. Configure Nginx

1) Add the contents of the HTTP node in the nginx.conf file

Upstream luxh-01.com {            server luxh-02.com:8080;            Server luxh-03.com:8080; }

2) Add the contents of the server node in the nginx.conf file

Location/{            Proxy_pass http://luxh-01.com;            Proxy_set_header X-real-ip $remote _addr; }

8. Deploy the application separately to the Tomcat server.

1) Start memcached service

2) Start Tomcat

3) Start Nginx

9. Direct access to Http://luxh-01.com/webapp (the project I deployed is accessed through WebApp)
