Linux安装Docker

Uninstall old versions

Older versions of Docker were called docker or docker-engine. If these are installed, uninstall them, along with associated dependencies.

sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

Install using the repository

Before you install Docker Engine for the first time on a new host machine, you need to set up the Docker repository. Afterward, you can install and update Docker from the repository.

SET UP THE REPOSITORY

Install the yum-utils package (which provides the yum-config-manager utility) and set up the stable repository.

 sudo yum install -y yum-utils

#使用官方镜像
 sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo
#使用阿里云加速
 sudo yum-config-manager \
 	--add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

INSTALL DOCKER ENGINE

1. Install the latest version of Docker Engine and containerd, or go to the next step to install a specific version:

   sudo yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin
   

   

2. To install a specific version of Docker Engine, list the available versions in the repo, then select and install:

   a. List and sort the versions available in your repo. This example sorts results by version number, highest to lowest, and is truncated:

   yum list docker-ce --showduplicates | sort -r
   

   The list returned depends on which repositories are enabled, and is specific to your version of CentOS (indicated by the .el7 suffix in this example).

   b. Install a specific version by its fully qualified package name, which is the package name (docker-ce) plus the version string (2nd column) starting at the first colon (:), up to the first hyphen, separated by a hyphen (-). For example, docker-ce-18.09.1.

   sudo yum install docker-ce-<VERSION_STRING> docker-ce-cli-<VERSION_STRING> containerd.io docker-compose-plugin
   

   This command installs Docker, but it doesn’t start Docker. It also creates a docker group, however, it doesn’t add any users to the group by default.

3. Start Docker.

    sudo systemctl status docker
    sudo systemctl enable docker
    sudo systemctl start docker
   

Uninstall Docker Engine

1. Uninstall the Docker Engine, CLI, and Containerd packages:

   sudo yum remove docker-ce docker-ce-cli containerd.io
   

2. Images, containers, volumes, or customized configuration files on your host are not automatically removed. To delete all images, containers, and volumes:

    #/var/lib/docker docker的默认工作路径！
    sudo rm -rf /var/lib/docker
    sudo rm -rf /var/lib/containerd
   

Configure mirror acceleration

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://yqtin9kc.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

Configure start-spring-io

1. install start-spring-io

   docker pull shizuwei/start-spring-io:1.0
   

2. run start-spring-io

   docker run -d -p 8090:8090 --restart=always --name start-spring-io shizuwei/start-spring-io:1.0
   

3. configure start-spring-io boot on start

   • check CONTAINER ID of start-spring-io

     docker ps --filter "name=start-spring-io"
     

     

   • update

     docker update --restart=always 9cfcf78c9b08
     

Configure mysql

1. install mysql

   docker pull mysql:5.7
   

2. run mysql

-p 3306:3306 将本机3306端口映射到docker的3306端口

-v 磁盘映射

docker run -d -p 3306:3306 --restart=always -v /mydata/mysql/conf:/etc/mysql/conf.d -v /mydata/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=root --name awei-mysql mysql:5.7

3. configure `msyql` boot on start

## Configure redis

1. upload redis.conf to /mydata/redis/conf

2. install redis

```shell
docker run -p 6379:6379 --name myredis --restart=always -v /mydata/redis/conf/redis.conf:/etc/redis/redis.conf -v /mydata/redis/data:/data -d redis:5.0 redis-server /etc/redis/redis.conf --appendonly yes
