How to build a tomcat cluster with nginx in Docker (illustrated in detail)

First of all, create a folder for tomcat. In order to facilitate the configuration of docker, I create it directly in the root directory. First step: create folder: publish folder.

Mkdir-p / docker/tomcat/webapp8081mkdir-p / docker/tomcat/webapp8082mkdir-p / docker/tomcat/webapp8083

Step 2: create a Tomcat container (the port can be changed according to your own reality)

Docker run-d-name tomcat8081-p8081: 8080-v / docker/tomcat/webapp8081:/usr/local/tomcat/webapps/ tomcatdocker run-d-name tomcat8082-p8082: 8080-v / docker/tomcat/webapp8082:/usr/local/tomcat/webapps/ tomcatdocker run-d-name tomcat8083-p8083: 8080-v / docker/tomcat/webapp8083:/usr/local/tomcat/webapps/ tomcat

After the creation is completed, use the docker ps command to check whether the creation is successful and use the

Step 3: check the IP of tomcat and use the command to query in turn. Only the first example is used here.

Docker inspect tomcat8081

Step 4: in order to facilitate testing, I will not upload the war package here, but create a hello/index.html file directly in it.

Note: if Nginx is a Docker container, you must use the Tomact container IP, otherwise you will not be connected

First download the official version of nginx on the official website.

Official website: http://nginx.org/en/

Click download in the navigation bar on the right, go to the download interface and select the corresponding version to download. I will use nginx-1.6.2.tar here.

When the download is complete, put the files in the custom folder, and I'll put them in / usr/local/tools/nginx-1.6.2 here.

Use this command to extract the nginx:

Tar vxf nginx-1.6.2.tar.gz

After unzipping, I am going back to the root directory and creating a host folder in the root directory in order to create files so that nginx can be mounted (you can also customize it)

Create a host folder here

Mkdir-p / docker/nginx/vim / docker/nginx/nginx.confmkdir-p / docker/nginx/html

Copy the page from the html folder in the negix you unzipped to the / docker/nginx/html folder

A conf file of negix is provided here, so you may change the format by adding comments. Remember to delete the comments.

Nginx.conf:

User root

Start using docker

Create and run the container

81: it is the port accessed by the public network. It can be modified according to the actual situation.

/ docker/nginx/nginx.conf local host file

/ etc/nginx/nginx.conf unzipped directory (may not be changed)

/ docker/nginx/html local host file

/ usr/share/nginx/html unzipped directory

Docker run-d-- name nginx81-p 81:80-v / docker/nginx/nginx.conf:/etc/nginx/nginx.conf-v / docker/nginx/html:/usr/share/nginx/html nginx

test

Http://39.106.147.162:8085/hello/index.html, port 8085 is configured here.
