Web application Building

Simple to construct a Web application, this is not described here, specifically to access my GitHub.
For ease of display, make a difference on success.jsp, one plus 8080, one plus 8081.

memcached installation, configuration, startup

This example uses 2 memcached nodes, all on one machine.

The operation on Win7 64. Resources can be downloaded on this link I am a link.
After decompression, enter cmd into this directory, remember to run as an administrator.

Installation

memcached  -d install

Run

-d start

You can also start multiple memcached services and refer to this link.

Create

create"Memcached Server"start= auto binPath= "memcached_path -d runservice -m 32 -p 11311 -l 127.0.0.1" DisplayName= "Memcached Server"

Note Modify the port, default is 11211
can be accessed via telnet: telnet 127.0.0.1 11211
Telnet interface quit to exit

To start, stop, and uninstall memcached server commands:

"Memcached Server"//启动"Memcached Server"//停止delete"Memcached Server"//卸载该服务

You can see the Memcached service on Task Manager

Tomcat Configuration

This time with 2 tomcat7.0.62 examples

Tomcat cluster configuration, each node in the cluster is shared by the session in the cache memcached by sharing: If a Tomcat service on one machine is stopped, Session data on other peer servers can still be read from the memcached cache, so there is no problem with session loss.

Use Memcached-session-manager, official documentation.

Tomcat configuration consists of two main aspects, first need to download the required package, placed in the Tomcat installation directory under the Lib directory (strictly speaking should be $catalina_home/lib/)
The jar required by the first MSM, the jar required for serialization,
A second configuration context.xml

Required JAR Packages

Memcached-session-manager

MAVEN Configuration for Tomcat 7
The following 3 jar packages are required;
Memcached-session-manager-version.jar,
Memcached-session-manager-tc7-version.jar,
Spymemcached-version.jar

Can be downloaded from maven below

<dependency><groupId>de.javakaffee.msm
   
    groupId><artifactId>memcached-session-manager-tc7
   
    artifactId><version>1.8.3

Serialization of

4 Kinds of serialization

The jar packages required for various serialization are as follows:
-Kryo-serializer:msm-kryo-serializer, Kryo-serializers, Kryo, Minlog, Reflectasm, ASM
-Javolution-serializer:msm-javolution-serializer, Javolution
-Xstream-serializer:msm-xstream-serializer, XStream, Xmlpull, xpp3_min
-Flexjson-serializer:msm-flexjson-serializer, Flexjson

$CATALINA _home/lib/add jar as follows

Context.xml Configuration

That is, modify the contents of the context node in the $catalina_home/conf/context.xml file to submit the MSM configuration.
This includes the use of memcached to manage sticky session and non-sticky sessions and the use of membase to manage non-sticky sessions.
The sample is based on the 2 memcached instances on a single host, and the example uses a serialization method of Kryo.

This time use sticky session to manage, as for non-sticky can be self-configuration or next time to add, configured as follows, 2 tomcat configuration.

  
       
   
    ...
   
    
     
    "de.javakaffee.web.msm.MemcachedBackupSessionManager"  memcachedNodes=
    
     "n1:localhost:11211,n2:localhost:11311"        sticky=
    
     "false" sessi>"false"        lockingMode=
    
     "auto"        requestUriIgnorePattern=
    
     ".*\.(ico|png|gif|jpg|css|js)$"transcoderFactoryClass=
    
     "de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory"/>
   
    
  
     

Nginx installation, configuration, startup

Download stable version on official website,

After extracting it into the directory,

start nginx  // 启动

In this way, the Nginx service is started. Open Task Manager to view the Nginx.exe process, with two processes showing up, consuming system resources, which is fairly small. Then open the browser, enter HTTP://127.0.0.1/can see Nginx welcome page, very friendly.

-s stop          // 停止nginx-s reload       // 重新加载配置文件-s quit          // 退出nginx

By default, Nginx uses the default configuration file, nginx.conf, to modify it as follows:

Test

Success Page
Success1

Success2

When the tomcat (8080) is turned off, call Tomcat (8081) to display the SUCCESS2;
When you close a memcached service, the display is normal.
