The following brings you how to use Nginx to achieve load balancing Tomcat cluster, hoping to give you some help in practical application, load balancing involves more things, there are not many theories, there are many books online, today we use the accumulated experience in the industry to do an answer.

I. tools

Operating system: win7

Nginx-1.13.5

Apache-tomcat-7.0.57

II. Objectives

Tomcat Cluster with High performance load balancing

III. Steps

1. Download Nginx first, and download the stable version:

2. Then decompress the two Tomcat

3. Modify the startup ports of the two Tomcat to 8180 and 8280, respectively. Take modifying the first Tomcat as an example, open server.xml under the conf directory of Tomcat.

The two tomcat modifications are the same as above, note that the ports must be different, I use 81 … And 82...

Create a test.war file, write an index.jsp page, and place it in the webapps directory, as follows:

Tomcat A

SessionID

Createdon

Then start the two Tomcat and visit it to see if it is normal.

6. After the above steps are successful, we can now configure Nginx to achieve load balancing, but we need to modify the Nginx configuration file.

The configuration is as follows (only a simple configuration has been made here, and the actual production environment can be configured in more detail):

Add the following code to the http module:

Gzip on

Upstream clarck.com {

Server 127.0.0.1:8180 weight=1

Server 127.0.0.1:8280 weight=2

}

Server_name localhost

Modify location / statement block

Location / {

Proxy_pass http://clarck.com;

Proxy_redirectdefault

}

Now that the configuration is complete, let's demonstrate load balancing.

7. Start two Tomcat CVMs first, and then start Nginx

8. Then we can enter: localhost/Test/index.jsp to check the health status

So far, we have implemented a load-balanced Tomcat cluster using Nginx. We keep refreshing and find that the probability of accessing Tomcat7_82 is about twice that of Tomcat1. This is due to the role of the weight of the two Tomcat that we configured in Nginx.

Read the above about how to use Nginx to achieve load balancing Tomcat cluster, if there is anything else you need to know, you can find what you are interested in in the industry information or find our professional and technical engineers to answer, technical engineers have more than ten years of experience in the industry.
