Distributed Web site Deployment

Environment Introduction: Two win2008_x64-bit host +jdk7_x64 bits are a host ip:192.168.7.100, B host ip:192.168.7.101

First, install the memcached (a host, b host need to install)

: http://download.csdn.net/detail/ttyyadd/9414586

Unzip to the local disk when the download is complete.

Open the CMD Command window to the directory where the Memcached.exe is located, and then execute the following command to install

After installation does not start need to go to service management inside find the memached service to start it.

Second, the following start configuration Tomcat6

1. First download the required jar

Place the downloaded jar under the Lib folder in the Tomcat directory

http://download.csdn.net/detail/ttyyadd/9414529

2. Start configuration (a host: 192.168.7.100) context.xml

<manager classname="De.javakaffee.web.msm.MemcachedBackupSessionManager"Memcachednodes="n1:192.168.7.100:11211,n2:192.168.7.101:11211"Failovernodes="N2"Requesturiignorepattern=".*\. (ICO|PNG|GIF|JPG|CSS|JS) $"Transcoderfactoryclass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory"/>

Start Configuration (Host B: 192.168.7.101) context.xml

<manager classname="De.javakaffee.web.msm.MemcachedBackupSessionManager"Memcachednodes="n1:192.168.7.100:11211,n2:192.168.7.101:11211"Failovernodes="N1"Requesturiignorepattern=".*\. (ICO|PNG|GIF|JPG|CSS|JS) $"Transcoderfactoryclass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory"/>

The note here is the Failovernodes property, which points to another host (not native).

3. Create a new test.jsp page, and place the root directory under Tomcat of host A and Host B, respectively

<%@ page language="java" %><%@ page import="java.util.*" %>System.  out . println (Session.getid ()); out. println ("<br> HostA hostb, SESSION ID:" + session.getid () +"  <br>"); %></body>
Third, configure Nginx
1, first download Nginx installation package
http://nginx.org/
2. Start configuring Nginx
Open the nginx.conf of the installation directory. My installation directory is (D:\nginx-1.9.9\conf\nginx.conf)
#user nobody;worker_processes1; #error_log logs/Error.log, #error_log logs/error.log notice; #error_log logs/error.log info; #pid logs/nginx.pid;events {worker_connections1024x768;}    HTTP {include mime.types; Default_type Application/octet-stream; #log_format Main'$remote _addr-$remote _user [$time _local] "$request"'    #                  '$status $body _bytes_sent "$http _referer"'    #                  '"$http _user_agent" "$http _x_forwarded_for "'; #access_log logs/Access.log Main;    Sendfile on;    #tcp_nopush on; #keepalive_timeout0; Keepalive_timeout $;  #gzip on; upstream Mysvr {#weigth参数表示权值, the higher the weight, the greater the probability of being assigned to it. 1.down indicates that the server is temporarily not participating in the load #2.

Save and close. nginx.conf file content is more, in fact, only need to modify the red font part
Then the cmd window into the installation directory to start the Nginx command is:
Start Nginx
Nginx Other Related commands:
1) Start Nginx:start nginx
2) Stop the Nginx:nginx-s stop
3) Reboot after configuration modification: Nginx-s Reload
Has now been configured to complete
Start visit: http://192.168.7.100/test.jsp
You can see that the session ID does not change.
