Nginx+tomcat+memcached sharing Session-id

I. Node information

192.168.1.133

Nginx

192.168.211.133

|

----------------------------------

| |

Tomcata (211.40) TOMCATB (211.132)

Memcachea (211.136) Memcachb (211.137)

Configure fixed IP

Turn off SELinux

Turn off iptables, boot does not start

Two. Principle

through Nginx proxy access back end Tomcat , and achieve memcache the same browser as the one accessed by the Session is the same.

Three. Deployment

Installation of the Tomcat service

A. Install the development environment Jdk-6u27-linux-i586.bin (32-bit)

installation package Download: Http://pan.baidu.com/s/1skqesVF nm9q

• chmod +x jdk-6u27-linux-i586.bin

• ./jdk-6u27-linux-i586.bin

For more information on what data registration collects and

How it's managed and used, see:

Http://java.sun.com/javase/registration/JDKRegistrationPrivacy.html

Press Enter to continue .....

Done.

Note: When the above information is installed, installing the JDK often reports many errors

eq: /lib/ld-linux.so.2:bad ELF interpreter description 64-bit system installed 32-bit program

Workaround: yum-y install glibc.i686 (recommended with CentOS from the Yum source, can be installed)

• MV JDK1.6.0_27/ETC/USR/LOCAL/JDK

• Defining variables used by the Tomcat service runtime

[email protected] ~]# VI/ETC/BASHRC

Export JRE_HOME=/USR/LOCAL/JDK

Export Java_bin=/usr/local/jdk/bin

Export path= $JRE _home/bin: $PATH

Export classpath=.: $JRE _home/lib/dt.jar: $JRE _home/lib/tools.jar

Export Jre_home java_bin PATH CLASSPATH

: Wq

[Email protected] ~]# SOURCE/ETC/BASHRC

B. Installing the Tomat package apache-tomcat-6.0.32.tar.gz

installation package Download: Http://pan.baidu.com/s/1boizwy7 2gwu

• TAR-ZXVF apache-tomcat-6.0.32.tar.gz

• MV Apache-tomcat-6.0.32/usr/local/tomcat

• NETSTAT-UNLATP |grep:8080

• Cd/usr/local/tomcat/bin

• ./startup.sh

• NETSTAT-UNLATP |grep:8080

TCP 0 0::: 8080:::* LISTEN 1879/java

Test: ip:8080 Whether the test page appears

Similarly: The second machine is set above, note IP

Installation of the Memcached service

A. Installing development tools

• Yum-y Install GCC make gcc-c++

B. Installing the Memcached Software

Note: libevent-2.0.15-stable.tat.gz must be installed before installing memcached software

installation package Download: Libevent:http://pan.baidu.com/s/1o6tpqia Lwyu

MEMCACHED:HTTP://PAN.BAIDU.COM/S/1I3LS6M5 8e52

• TAR-ZXVF libevent-2.0.15-stable.tar.gz

CD libevent-2.0.15-stable

./configure && make && make install

• TAR-ZXVF memcached-1.4.5.tar.gz

CD memcached-1.4.5

./configure && make && make install

• Vim/etc/ld.so.conf.d/libevent.conf

/usr/local/lib/

: Wq

Ldconfig-v

• /usr/local/bin/memcached-u root-m 100m-n 10-f 2-d-VVV

Options:

-H View Help information

-p Specifies the port number of the memcached listener default 11211

-L memcached Server IP address

-U memcached the user identity used when running the program must be the root user

-m specifies how much physical memory to use this computer default 64M

The maximum number of links to the-C memcached service

-VVV Show Details

-N Chunk the minimum space of a size is how many units of bytes

-F Chunk Size growth multiplier by default 1.25 times times

-D starts in the background

• Netstat-utnlap | grep:11211

Knowledge Points:

kill-9 PID number kills memcached process (process number)

Pkill-9 memcached Kill memcached Process (process name)

Killall-9 memcached kills all memcached processes

• Test memcached:

[[Email protected] ~]# telnet localhost 11211

Trying 192.168.1.10 ...

Connected to 192.168.1.10 (192.168.1.10).

Escape character is ' ^] '.

Set name 0 180 3//0 fixed format 180 180 seconds 3 3 bytes

Similarly: The second machine is configured as above, note IP

Tomcat and memcached Connection tool Memcached+session+manager

installation package Download: Http://pan.baidu.com/s/1YYfiY u9dl

A. Unpacking the installation package

B. Installation and Configuration

Install and configure the following on two tomcat servers:

• CD session

• CP *.jar/usr/local/tomcat/lib/

• cd/usr/local/tomcat/conf///Configure Tomcat configuration file to connect to the specified memcached server

VI contest.conf//insert the following lines of text

<Context>

......

......

<manager classname= "De.javakaffee.web.msm.MemcachedBackupSessionManager"

memcachednodes= "n1:192.168.211.142:11211 n2:192.168.211.143:11211"

Requesturilgnorepattern= ". *\ (ICO|PNG|GIF|JPG|CSS|JS) $"

Transcoderfactoryclass= "De.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory"

/>

</Context>

• Restart the Tomcat service

Installation of Nginx Service

A. Install the development environment

• Yum-y Install GCC make gcc-c++

• Yum-y install pcre pcre-devel OpenSSL openssl-devel

B. Installing Nginx Service

installation package Download: Http://pan.baidu.com/s/1c1nhg2G 5QPN

• Useradd Nginx

• TAR-ZXVF nginx-1.0.5.tar.gz

• CD nginx-1.0.5

• ./configure--prefix=/usr/local/nginx--user=nginx--group=nginx--with-http_ssl_module--with-http_stub_status_ Module

• Make && make install

• Cd/usr/local/nginx/conf

• Modify the configuration file (the original file is best backed up)

HTTP {

Upstream Tomcatgrp {

Server 192.168.1.10:8080;

Server 192.168.1.20:8080;

}

server {

...

...

Location/{

root HTML;

Index index.html index.htm;

Proxy_pass http://tomcatgrp;

}

......

......

}

}

: Wq

• test that the configuration file is correct./nginx-t

• ./nginx

Test

A. By entering the Nginx URL to see if the color of the page is flexible, the session is not changed

Test page Download :Http://pan.baidu.com/s/1bjNxTG 9br2

The test is also placed in the cd/usr/local/tomcat/webapps/root/directory, and two tomcat tests will be changed, each tomcat color is not the same can be
