常见问题解决：Docker篇

1、Linux下安装Docker

安装Docker的前提是：内核版本必须是3.10及以上

# 查看内核版本
uname ‐r

# 安装docker
[[email protected] ~]# yum install docker
# 启动docker
[[email protected] ~]# systemctl start docker
# 查看docker启动状态
[[email protected] ~]# systemctl status docker
# 开启启动docker
[[email protected] ~]# systemctl enable docker
# 停止docker
[[email protected] ~]# systemctl stop docker

2、使用Docker安装Redis并使用Redis客户端

# 使用国内镜像加速
[[email protected] ~]# docker pull registry.docker‐cn.com/library/redis
[[email protected] ~]# docker images
REPOSITORY                             TAG                 IMAGE ID            CREATED             SIZE
registry.docker-cn.com/library/redis   latest              0f55cf3661e9        12 days ago         95 MB
[[email protected] ~]# docker run -d -p 6379:6379 --name myredis 0f55cf3661e9
e0ee9b72fabfd936f4e46705c85dd849585aa46bf6a44f4627b7c461a3dc7b6f
[[email protected] ~]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES

# 启用Redis客户端
[[email protected] ~]# docker exec -it myredis redis-cli

3、使用Docker安装MySQL

[[email protected] scripts]# docker pull registry.cn-hangzhou.aliyuncs.com/hhzz/mysql
[[email protected] scripts]# docker images
REPOSITORY                                     TAG                 IMAGE ID            CREATED             SIZE
registry.cn-hangzhou.aliyuncs.com/hhzz/mysql   latest              1ba555be37dc        3 years ago         360 MB
[[email protected] scripts]# docker run -p 3306:3306 --name mysql  -e MYSQL_ROOT_PASSWORD=123456 -d 1ba555be37dc
