First, make sure docker state has been running, and make sure the firewall is turned off (or ip and port access)
Second, download the image
1, image search
docker search mysql
We see the first official mysql, but if you use docker pull mysql
will pull the latest version of the image, which is version 8.0, how to pull that specified version of it?
Need to enter the address:
https://hub.docker.com
we see version 5.7, we used version 5.7
How to specify version?
pull imageName Docker: Tag
imageName: Mirror Name
tag: version number
2, image taking Pull 5.7
docker pull mysql:5.7
- View Mirror
docker images
Third, start containers, and configure the mount directory
1. Create a directory to mount
mkdir -p /data/mysql5.7/logs /data/mysql5.7/conf /data/mysql5.7/data
cd /data/mysql5.7/
ll
2, using a mirror to create a container
docker run -di --name=mysql-pro -p 3306:3306 -v /data/mysql5.7/data:/var/lib/mysql -v /data/mysql5.7/conf:/etc/mysql/conf.d -e MYSQL_ROOT_PASSWORD=123456 mysql:5.7
Parameter analysis:
Docker run: Create a container
-d: run behind the -d parameter will create a guard vessel in the background (this will not automatically logged container after container is created, if only two plus -i -t parameters, after you create will automatically go in the container).
-i: Run indicates a container
-p: mapping the port, the former is a host port, which is mapped in the port of the container. You can use multiple -p do more port mapping
-v: representing the directory mapping relationship (the former is the host directory, which is mapped to a directory on the host), you can use multiple -v do multiple directories or file mappings . Note: It is the directory for mapping, making changes on the host, and then to share the container.
-e: set environment variables, here designated root password
mysql: 5.7: image name used
Tips:
(in this way will replace /etc/mysql/conf.d/ following three files to an external mounted my.cnf file, that is to say, in this way to mount the directory, container directory consistent with the external file directory contents)
ok, run successfully. have a test
success.
Fourth, look at the mount directory, look at the results
cd /data/mysql5.7/
ll
The following data is data
cd data/
Look at the mirror and have already initiated container
docker images
docker ps
Well, is completed, the next chapter update docker redis installation and configuration mount
