Nginx+tomcat cluster environment construction

Experimental environment: windows xp sp3

​

Nginx version: 1.5.12;

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

​

Tomcat version: 6.0.39

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

​

1. Configure nginx

1. Create an nginx folder in the root directory of drive D, and extract the downloaded nginx release package nginx-1.5.12.zip to this directory.

2. D:nginxnginx-1.5.12 directory structure

3. Start nginx

Starting nginx under windows is very simple, just double-click to run nginx.exe. Nginx runs on port 80 by default. To check whether nginx is started, we only need to enter http://localhost in the browser and you will see the following page, indicating that our nginx has been started.

1. Stop nginx

If you need to stop nginx, you need to open a command line window, enter the directory where nginx is decompressed, that is, enter the directory where the nginx.exe file is located, and enter the command nginx –s stop to stop nginx.

​

2. Cluster configuration

1. Configure tomcat

Create a tomcat folder in the root directory of drive D, and unzip two copies of the tomcat6.0.39 release package into this directory, naming them tomcat01 and tomcat02 respectively. In order to easily observe which tomcat we are accessing, we modify the D:tomcattomcat01webappsROOTindex.html of tomcat01

[html] view plaincopy

1. b> Apache Tomcatb>td> changed to [html] view plaincopy b> Apache Tomcat 1

b

>

td

>

1. Similarly, we put tomcat02’s D:tomcattomcat02webappsROOTindex.html in [html] view plaincopy
   1. b> Apache Tomcatb>td> changed to [html] view plaincopy b>
   Apache Tomcat 2
   b

   >

   td
   >
   1. We have two tomcats on the same computer. In order to prevent the ports of the two tomcats from conflicting, we put tomcat02’s D:tomcattomcat02confserver.xml [html] view plaincopy <Server port="8005"shutdown="SHUTDOWN">
   changed to
   
   
   [html] view plaincopy

   1. <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />  
   改为

   2、  配置nginx

   }
   85. 3. View the reverse proxy configuration results Start nginx, tomcat01, tomcat02.
   86. Enter http://localhost in the browser and you will see the management interface of tomcat01, as shown below.
   
   

   Then transparently stop tomcat02, refresh the page, and nginx automatically switches to tomcat02 for us, as shown below.

   

   
   

   

   
   

   The above introduces the establishment of Nginx+tomcat cluster environment, including the relevant aspects. I hope it will be helpful to friends who are interested in PHP tutorials.
