Turn "NGINX+TOMCAT cluster environment Setup (under Windows)

Original blog from: http://blog.csdn.net/clj198606061111/article/details/22621003 thanks!

Experimental environment

Windows XP SP3

Nginx version: 1.5.12;

: http://nginx.org/en/download.html

Tomcat version: 6.0.39

: http://tomcat.apache.org/download-60.cgi

First, the configuration Nginx

1, in the D packing directory to establish Nginx folder, the download Nginx release package Nginx-1.5.12.zip extracted to the directory.

2. D:\NGINX\NGINX-1.5.12 directory Structure

nginx-

|_ conf Configuration directory

|_ contrib.

|_ Docs Documentation Directory

|_ Logs Log directory
|_ Temp Temporary file directory

|_ HTML Static page directory

|_ Nginx.exe Main Program

3. Start Nginx

Windows Start Nginx is very simple, double-click Run Nginx.exe can. Nginx is running on the 80 port by default, check if Nginx is started we only need to enter http://localhost in the browser to see the following page, indicating that our nginx has been set up.

1. Stop Nginx

If you need to stop nginx, you need to open a command line window, into the Nginx decompression directory, that is, enter the directory where the Nginx.exe file, enter the command nginx–s stop can stop nginx.

Second, cluster configuration

1. Configuring Tomcat

Build the Tomcat folder in the D packing directory and extract 2 copies of the tomcat6.0.39 release package to this directory, named Tomcat01,tomcat02. To make it easy to see which Tomcat we're visiting, we modified TOMCAT01 's D:\tomcat\tomcat01\webapps\ROOT\index.html

<td align= "left"  valign= "top" span class= "tag" >><b>apache tomcat< span class= "tag" ></b></ td>  

<TD Align="left" valign="Top"><b>apache Tomcat 1</b ></td>

In the same vein, we put Tomcat02 's D:\tomcat\tomcat02\webapps\ROOT\index.html

< span class= "tag" ><td align= "left"  valign= "top" span class= "tag" >><b>apache tomcat< span class= "tag" ></b></ td>  

Switch

<TD Align="left" valign="Top"><b>apache Tomcat 2</b ></td>

2 Tomcat we are on the same computer, in order to let 2 tomcat ports do not conflict, we put tomcat02 in the D:\tomcat\tomcat02\conf\server.xml

<Server port="8005" shutdown="shutdown">

Switch

<Server port="8105" shutdown="shutdown">

<Connector port="8080" protocol="http/1.1 "

connectiontimeout="20000"

　　　　redirectport="8443" />

Switch

<Connector port="8180" protocol="http/1.1 "

connectiontimeout="20000"

　　　　redirectport="8543" />

<Connector port="8009" protocol="ajp/1.3" redirectport="8443" />

Switch

<Connector port="8109" protocol="ajp/1.3" redirectport="8543" />

2. Configure Nginx

114. Server localhost:8080;

118. }
124. server {

164. Location =/50x.html {

168. }
172. }
174. }

3. View reverse proxy configuration results

Start Nginx, tomcat01, tomcat02.

Browser input http://localhost will see the tomcat01 management interface, such as.

Then transparent stop tomcat02, refresh the page, Nginx automatically help us to switch to tomcat02, such as.

Go to Nginx+tomcat cluster environment (under Windows)
