Configuring cluster load Balancing with NGINX+TOMCAT under Windows

Nginx is a lightweight Web server/reverse proxy server, more detailed interpretation of their own Baidu. At present, such as Sina, NetEase and so on are using it. First of all, my server Software environment:

System: windows_server_2008_standard_enterprise_and_datacenter_with_sp2_x64

Currently running Tomcat: non-installable version of Tomcat 6.0.36

Just say these two key points, the problem is that the number of visits to a single tomcat has been unable to load, often a time-out situation. So the plan to use Nginx layout load balancer, the data found on the network is the introduction of the Linux version of Nginx layout and use, but in Windows if the use of Linux version of Nginx can only do a test, the actual production environment is not available, will report the following error:

Maximum number of descriptors supported by select () is 1024x768 while waiting for request

This is because the number of file access handles is limited to 1024 and will not respond when the traffic is large. Go to the Internet have looked up a lot of information that is modified parameters worker_connections can solve this limitation, there are many other said to modify worker_rlimit_nofile parameters, etc., have tried but all failed. In the preparation of other tools in a foreign forum to see a reply, the address does not remember, said that there is a special version of the Windows Nginx, has modified the file handle data restrictions. After downloading, it is true that the configuration runs OK successfully. As long as the download to the correct version of the configuration is still easy. The following is the download configuration process ha ~ ~

Nginx for Windows official website: http://nginx-win.ecsds.eu/

Nginx for Windows download address: http://nginx-win.ecsds.eu/download/

I downloaded the nginx 1.7.7.1 whiterabbit.zip This version, too new version I am afraid of instability. After download, unzip the installation package, there is a brief update information and Installation Guide Readme Nginx-win version.txt. Key information is as follows:

Default installation instructions;* New:unzip This version with folder structure* Old:overwrite with this version* C Heck nginx.conf, nginx-org.conf and nginx-win.conf* Windows optimization registry File:check your current values before s Etting the new ones

Locate the nginx-win.conf in the Conf folder, copy it to nginx.conf, and then configure it in this file, my configuration file is as follows:

#user nobody;# Multiple workers works!# number of worker processes: This value is configured based on the number of server CPU cores, such as the 6-core 12-thread CPU can be configured to 6 or 12.

The configuration of Tomcat is relatively simple, it is to copy a change three ports. Specific own Baidu.

Configuration is complete, run Nginx.exe and Tomcat to verify the configuration.

Nginx Start-up control I used a friend's script on the Internet, the address is as follows:
