Http://pan.baidu.com/s/1pJlZ0mB//related package download, including the required Jar package Lib

Environment: CentOS 6.5 (64-bit), Jdk8_8u5, tomcat7.054, nginx1.47, libevent-2.0, memcached-1.4.20

Tomcat machine configuration

1. Uninstall your own JDK with RPM package installation

Rpm–qa |grep java | Xargs rpm-e--nodeps//Bulk uninstall of your own JDK-related packages

2, RPM installation

RPM-IVH jdk-8u5-linux-x64.rpm//default installation in/usr/java

Change the MV name to/USR/JAVA/JDK

Java-version//Verify the installation was successful

3. Write Environment

Vim/etc/profile

Java_home=/usr/java/jdk

Jre_home=/usr/java/jdk/jre

Path= $PATH: $JAVA _home/bin: $JRE _home/bin

Classpath=.: $JAVA _home/lib/dt.jar: $JAVA _home/lib/tools.jar: $JRE _home/lib

Export Java_home jre_home PATH CLASSPATH

4. Unzip the Tomcat test run

TAR–ZXF apache-tomcat-7.0.54.tar.gz& #160; -c/usr/local

6. Change the Tomcat session Save method (Non-sticky,kryo

The following contents are added to the configuration file.

Vim Conf/context.xml

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

Nginx Installation Configuration

1. Source Package Installation

#yum Install pcre*//nginx relies on Pcre class library

#useradd Nginx

#tar xf/share/soft/lamp/nginx/nginx-1.4.7.tar.gz-c/usr/src/

#cd/usr/src/nginx-1.4.7

#./configure--prefix=/usr/local/nginx--user=nginx--group=nginx--with-http_gzip_static_module--with-http_stub_ Status_module

# Make && make install

2.nginx reverse proxy, implement load balancer agent behind two tomcat servers

User Nginx Nginx;

Worker_processes 5;

Error_log Logs/error.log;

#error_log Logs/error.log Notice;

#error_log Logs/error.log Info;

PID Logs/nginx.pid;

Events {

Worker_connections 1024;

Use Epoll;

}

HTTP {

Upstream Session {

Server 10.1.1.217:8080 weight=1 max_fails=2 fail_timeout=30s;

Server 10.1.1.218:8080 weight=1 max_fails=2 fail_timeout=30s;

}

server {

Listen 80;

server_name 10.1.1.217;

root/nginxroot/;

Location ~ \. (txt|jsp) $ {

Proxy_pass http://session;

}

Proxy_set_header X-real-ip $remote _addr;

Proxy_set_header x-forwarded-for $proxy _add_x_forwarded_for;

Proxy_set_header Host $http _host;

}

}

mkdir/nginxroot/

The above is a simple implementation of the JSP access to the balanced scheduling, the experiment casually changed

memcached installation//installation Libevent (memcached dependent libevent)

1. Installation

#tar ZXVF libevent-2.0.21-stable.tar.gz

#cd & #160; ZXVF libevent-2.0.21-stable

#./configure--PREFIX=/USR

#make && make Install

# tar ZXVF memcached-1.4.20.tar.gz

#cd memcached-1.4.20

#./configure--WITH-LIBEVENT=/USR

#make && make Install

2. Start, Close command

Start-D background run –m memory size –p port –c max concurrency

/usr/local/bin/memcached-d-M 128-u root-p 11211-c 256-p/var/run/memcached.pid

Kill ' Cat/var/run/memcached1.pid ' & #160; Shut down

http://hxq0506.iteye.com/blog/1388971//reference links

Test:

Boot order tomcat–nginx–memcached

Test page test.jsp, put webapps/root:

Server Info:

Sessionid:<%=session.getid ()%>

<br>

Sessionip:<%=request.getservername ()%>

<br>

Sessionport:<%=request.getserverport ()%>

<br>

<%

OUT.PRINTLN ("127"); Mark Back-end nodes

%>

Result: Session remains unchanged
