First create the tomcat folder. In order to facilitate the configuration of docker, I will create it directly in the root directory. Step 1: Create the folder: publish the folder

mkdir -p /docker/tomcat/webapp8081

mkdir -p /docker/tomcat/webapp8082

mkdir -p /docker/tomcat/webapp8083

Copy after login

Step 2: Create a tomcat container (the port can be changed according to your actual situation)

docker run -d --name tomcat8081 -p 8081:8080 -v /docker/tomcat/webapp8081:/usr/local/tomcat/webapps/ tomcat
docker run -d --name tomcat8082 -p 8082:8080 -v /docker/tomcat/webapp8082:/usr/local/tomcat/webapps/ tomcat
docker run -d --name tomcat8083 -p 8083:8080 -v /docker/tomcat/webapp8083:/usr/local/tomcat/webapps/ tomcat

Copy after login

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

Step 3: Check tomcat’s ip. Use the command to query. Only the first example is used.

docker inspect tomcat8081

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

Note: If nginx is docker The container must use the tomact container ip, otherwise it will not be connected.

First download the official version of nginx from the official website

Official website:

Click download on the right navigation bar to enter the download Select the corresponding version in the interface to download. I will use nginx-1.6.2.tar

After the download is completed, put the file in a custom folder. Here I will Place it in /usr/local/tools/nginx-1.6.2

Use this command to decompress nginx:

tar vxf nginx-1.6 .2.tar.gz

After decompression is completed, I return to the root directory and create a host folder in the root directory. The purpose is to create files so that nginx can be mounted (you can also Customized)

Create the host folder here

mkdir -p /docker/nginx/
vim /docker/nginx/nginx.conf
mkdir -p /docker/nginx/html

Copy after login

Copy the index.html 50x.html in the html folder in negix you decompressed to the /docker/nginx/html folder

Here is a negix conf file. If you add annotations, the format may change. Remember to delete the annotations.

nginx.conf:

Use docker to start

Create and run the container

81:Yes The port for external network access can be modified according to the actual situation

/docker/nginx/nginx.conf The local host file

/etc/nginx/nginx.conf The decompressed directory (it can also be used without Change)

/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 What I configure here is port 8085
