Nginx+tomcat build high-performance load Balancing cluster-windows local beta

First, install Tomcat and Nginx

First install two apache-tomcat-8.0.41,:http://tomcat.apache.org

and install a nginx-1.13.0,http://nginx.org/en/download.html

are green version, directly decompression can be used, do not need to do environment variables and other configuration.

Here is a small problem: the company's computer environment variables with the JDK6, so my Tomcat8 start when the black window flashed, JDK version does not match the reason, the jdk6 replaced Jdk8, Tomcat8 normal start.

Second, modify the Tomcat port number

My first Tomcat is the default, just modify the second tomcat, make sure two Tomcat can start at the same time, need to modify the port number in the following three places (O (∩_∩) o I just added 1~ in the default multi-slogan):

Third, modify Tomcat's default page to identify which Tomcat is accessed

Another tomcat here is to add the =====TOMCAT1

Four, modify the configuration of Nginx

In fact, the following two places have been modified:

Five, start testing

Launch two Tomcat directly via Startup.bat. There will be two black windows with Tomcat's boot log.

Then through the Nginx directory of the Nginx.exe to start Nginx.

Vi. test Results

As shown, the browser accesses localhost, constantly refreshed, access to Tomcat will switch back and forth in 1 and 2, the probability of switching is determined by the configured weights.
