Installation docker: yum install docker
Start docker Services: systemctl start docker
Set docker service boot from the start: systemctl enable docker way to determine if prompted, press Y and Enter.
Test whether the installation was successful docker: docker ps -a
Container operation:
docker stop container id
docker start container id
docker restart container id
Lists all currently running: docker ps
View all containers, including the closure of: docker ps -a
What some view current images: docker images
下载image：docker pull image-name

Force the removal of the container, regardless of whether you are running: Docker RM - f
A: Installing MySQL
docker pull mysql:5.71：
Create mysql: 5.7 Data storage directory
mkdir /data/docker/mysql1
cd /data/docker/mysql1
mkdir data
2: Create a temporary msyql: 5.7 container, the aim cp container mysql configuration file
3: Copy mysql container configuration file to the specified directory host
4: Copy the files out of the container from the command:
dokcer cp container name: container directories need to copy files or directories docker cp myMysql: / etc / mysql / data / docker / mysqle1 copied directory structure (be careful not to modify the mysql directory after copy, otherwise the contents inside the profile required re repair
5: Delete temporary mysql container (rm -f stop and delete)
docker rm -f myMysql
6: We configured startup command execution
docker run -d --name mysql1 -p 33306:3306 --restart always --privileged=true -v /data/docker/mysql1/mysql:/etc/mysql -v /data/docker/mysql1/data:/var/lib/mysql -e MYSQL_USER="lwj" -e MYSQL_PASSWORD="123456" -e MYSQL_ROOT_PASSWORD="admin123" -v /etc/localtime:/etc/localtime mysql:5.7
7: command interpreter:
--restart always -> boot --privileged = to true -> the hoisting container permissions -v / data / docker / mysql1 / mysql: / etc / mysql -> mapping configuration file -v / data / docker / mysql1 / data: / var / lib / MySQL -> map data directory -e mysql_user = " lwj " -> Add user lwj -e MYSQL_PASSWORD = " 123456 " -> set lwj user's password is 123456 -e MYSQL_ROOT_PASSWORD = " admin123 " -> set the root the password is admin123
2 Install Tomcat
docker pull tomcat:8.5
docker run -d -p 8081:8080 --name tomcat1 --restart=always -v /data/docker/nginx/www:/home -v /data/docker/tomcat1/root:/root -v /data/docker/tomcat1/webapps:/usr/local/tomcat/webapps -v /etc/localtime:/etc/localtime --network network1 tomcat:8.5
docker run -d -p 8082:8080 --name tomcat2 --restart=always -v /data/docker/nginx/www:/home -v /data/docker/tomcat2/root:/root -v /data/docker/tomcat2/webapps:/usr/local/tomcat/webapps -v /etc/localtime:/etc/localtime --network network1 tomcat:8.5
Into the container
docker exec -it “CONTAINER ID”/bin/bash
The time zone added to the list
echo "Asia/Shanghai" > /etc/timezone
Exit container
exit
Restart container
docker restart “CONTAINER ID”
