I. Topology



II. Environment Installation

Install memcached's direct yum

[[Email protected] ~] # Yum-y install memcached

[[Email protected] ~] # Service memcached start

Starting memcached: [OK]

[[Email protected] ~] # SS-anlpt | grep memcached

Listen 0 128: 11211: * Users :( ("memcached", 262.16,27 ))

Listen 0 128 *: 11211 *: * Users :( ("memcached", 262.16,26 ))

[[Email protected] ~] #


Because Tomcat depends on the Java environment, install JDK first (Tomcat a B is the same)

[[Email protected] SRC] # rpm-IVH jdk-7u9-linux-x64.rpm

[[Email protected] SRC] # Vim/etc/profile. d/Java. Sh

Java_home =/usr/Java/jdk1.7.0 _ 09

Path = $ java_home/bin: $ path

Export java_home

[[Email protected] SRC] # source/etc/profile. d/Java. Sh


Install Tomcat

[[Email protected] SRC] # tar xf apache-tomcat-7.0.42.tar.gz-C/usr/local/

[[Email protected] SRC] # cd/usr/local/

[[Email protected] local] # ln-sv apache-Tomcat-7.0.42/tomcat

'Tomcat '-> 'apache-Tomcat-7.0.42 /'

[[Email protected] Tomcat] # Vim/etc/profile. d/tomcat. Sh

Export catalina_home =/usr/local/tomcat

Export Path = $ catalina_home/bin: $ path

[[Email protected] Tomcat] # source/etc/profile. d/tomcat. Sh

[[Email protected] Tomcat] # Catalina. Sh version # view the version

[[Email protected] Tomcat] # Catalina. Sh start # Start


Modify the tomcat configuration file (A and B are the same)

Configure session sharing memcache, which is placed under the Lib of two Tomcat servers.

Javolution-5.4.3.1.jar

Memcached-session-manager-1.8.1.jar

Memcached-session-manager-tc7-1.8.1.jar Z

Msm-javolution-serializer-1.8.1.jar

Spymemcached-2.10.2.jar


[[Email protected] Tomcat] # Vim CONF/context. xml

<Context>

<Manager classname = "De. javakaffee. Web. MSM. memcachedbackupsessionmanager"

Memcachednodes = "N1: 192.168.83.134: 11211"

Failovernodes = "N1"

Requesturiignorepattern = ". * \. (ICO | PNG | GIF | JPG | CSS | JS) $" transcoderfactoryclass = "De. javakaffee. Web. MSM. serializer. kryo. kryotranscoderfactory"

/>

</Context>

Provide a test page for Tomcat

#### Tomcat ##########

[[Email protected] Tomcat] # mkdir-PV/usr/local/tomcat/webapps/test/WEB-INF/{classes, lib}

[[Email protected] Tomcat] # Vim/usr/local/tomcat/webapps/test/index. jsp

<HTML>

<Head> <title> tomcata </title>

<Body>

<H1> <font color = "red"> tomcata.magedu.com </font>

<Table align = "center" border = "1">

<Tr>

<TD> session ID </TD>

<% Session. setattribute ("magedu.com", "magedu.com"); %>

<TD> <% = session. GETID () %> </TD>

</Tr>

<Tr>

<TD> created on </TD> <% = session. getcreationtime () %> </TD>
