Tomcat+memcached Implementing sessions sharing

Before the company used this, also simply wrote a document, and later found not enough detail to write so that others see my document, always overwhelmed, this time to write a detailed, share to you just contact this technology small partner!!!

Lab environment: Virtual machine centos6.6_x89_64 minal mode

Software version: apache-tomcat-7.0.64.tar.gz

Jdk-7u45-linux-x64.tar.gz

Libevent-2.0.21-stable.tar.gz

Memcached-1.4.21.tar.gz

And the jar packages that are relative to the Tomcat version

Turn off SELinux and firewalls before you experiment

Service Iptables Stop

This experiment will also use some basic dependency packages if you feel that they are not installed, you can run the command to prevent the subsequent compilation error.

Yum groupinstall-y Development Tools

All right, no nonsense, go!. Go! Go!

1. All packages are placed in/usr/local/src/

[Email protected] ~]# cd/usr/local/src/

[email protected] src]# LL

2. Install Java and configure environment variables, detect JDK version

[Email protected] src]# tar zxvf jdk-7u45-linux-x64.tar.gz

[Email protected] src]# MV jdk1.7.0_45//USR/LOCAL/JDK7

[Email protected] src]# Vim/etc/profile

..........................................................

Export JRE_HOME=/USR/LOCAL/JDK7

3. Install Tomcat

[Email protected] src]# tar zxvf apache-tomcat-7.0.64.tar.gz

[Email protected] src]# MV Apache-tomcat-7.0.64/usr/local/tomcat

[Email protected]test13 src]# vim/usr/local/tomcat/bin/catalina.sh

4. Compile and install memcached

[[email protected] src]# CP serssion-jar/*/usr/local/tomcat/lib///Put the MSM-dependent jar package under $tomcat_home/lib

[Email protected] src]# tar zxvf libevent-2.0.21-stable.tar.gz

[Email protected] src]# CD libevent-2.0.21-stable

[Email protected] libevent-2.0.21-stable]#/configure--prefix=/usr/local/libevent

[[email protected] libevent-2.0.21-stable]# make && make install

#每次编译最好用 echo $? To see if the compilation was successful

[Email protected] libevent-2.0.21-stable]# CD.

[Email protected] src]# tar zxvf memcached-1.4.21.tar.gz

[Email protected] src]# CD memcached-1.4.21

[Email protected] memcached-1.4.21]#/configure--prefix=/usr/local/memcached--with-libevent=/usr/local/libevent

[[email protected] memcached-1.4.21]# make && make install

[[email protected] memcached-1.4.21]# echo $?

0

5. Modify the Tomcat configuration file

[Email protected] memcached-1.4.21]# cd/usr/local/tomcat/

[Email protected] tomcat]# vim Conf/server.xml

..........................................................

<engine name= "Catalina" defaulthost= "localhost" jvmroute= "jvm1" >

#如果要配置通一台机器上的多个tomcat, then jvmroute the label to be changed to a different

6. Start memcached

[Email protected] memcached]# bin/memcached-d-m 256-p 11211-u Root

#重启tomcat

[[Email protected] memcached]# PS aux |grep Tomcat
