Docker安装

docker ce 社区版本

docker ee 企业版本

  1. 关于centos-extras存储库开启访问此地址
  2. 开启overlay2存储驱动

Install using the repository

  1. 安装需要的包

yum install -y yum-utils \                  provides the yum-config-manager utility
    device-mapper-persistent-data lvm2      required by devicemapper
  1. 设置仓库

yum install docker-ce docker-ce-cli containerd.io

If prompted to accept the GPG key, verify that the fingerprint matches 

060A 61C5 1B55 8A7F 742B 77AA C52F EB6B 621E 9F35,

and if so, accept it.

当你有多个Docker仓库，执行安装默认会安装最高版本的Docker。

执行完成后Docker就已经安装好，并且Docker用户组也一并创建，但是没有用户添加到组中。

  1. 安装指定版本的Docker

    列出repo中可用版本yum list docker-ce –showduplicates | sort -r

    执行更新源yum update在执行以上命令。

  1. 启动docker服务

    systemctl start docker

Install from a package

  1. 从以下地址下载对应版本的docker-ce 和 docker-ce-cli

  2. 执行安装命令 yum install ./*.rpm 把3个rpm包放在同一个目录执行即可。

  3. 安装完成执行service docker start，执行docker info。

  4. 升级docker To upgrade Docker CE, download the newer package file and repeat the installation procedure, using yum -y upgrade instead of yum -y install, and pointing to the new file.

  5. usermod -aG docker your-user 把执行用户追加到docker用户组。注销并重新登录才能生效！

root权限创建data目录，容器启动会失败，存在数据，重新构建容器也会失败。

docker pull mysql
docker pull adminer
docker run --restart=always \
           --name docker_mysql \
           -e MYSQL_ROOT_PASSWORD=a123456 \
           -e MYSQL_USER=cboard \
           -e MYSQL_PASSWORD=cboard \
           -e MYSQL_DATABASE=cboard \
           -p 3306:3306 \
           -d \
           -v `pwd`/data:/var/lib/mysql \
           -v `pwd`/conf:/etc/mysql \
           mysql \
           --character-set-server=utf8mb4 \
           --collation-server=utf8mb4_unicode_ci \
           --default-authentication-plugin=mysql_native_password

docker run --link docker_mysql:mysql --name adminer -p 8888:8080 -d --restart=always adminer

MYSQL_RANDOM_ROOT_PASSWORD=yes 将会为root用户设置随机密码。
MYSQL_ONETIME_PASSWORD=yes 将会在首次登录的时候强制更改密码。

docker run -it\
           --link docker_mysql:mysql\
           --rm mysql \
           sh -c 'exec mysql -h"$MYSQL_PORT_3306_TCP_ADDR" -P"$MYSQL_PORT_3306_TCP_PORT" -uroot -p"$MYSQL_ENV_MYSQL_ROOT_PASSWORD"'

docker exec -it docker_mysql bash
docker logs docker_mysql
docker container rm -f docker_mysql
docker ps
dcoker container ls -a

修改MYSQL密码
ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';
