Docker安装及MySQL、Redis等配置

Docker安装（CentOS版本）

Docker安装文档：链接
1、卸载系统之前的docker

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

2、安装依赖包

sudo yum install -y yum-utils device-mapper-persistent-data lvm2

3、设置docker repo的yum位置，告诉os去哪里安装docker

sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

4、安装docker和docker-cli

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

5、启动docker

sudo systemctl start docker

6、设置docker开机自启

sudo systemctl enable docker

7、配置docker镜像加速

sudo mkdir -p /etc/docker

sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors":["https://82m9ar63.mirror.aliyuncs.com"]
}
EOF

sudo systemctl daemon-reload

sudo systemctl restart docker

Docker安装MySQL

docker常用镜像安装网址：链接
1、指定安装版本为5.7进行mysql安装

docker pull mysql:5.7

2、创建实例并启动

docker run -p 3306:3306 --name mysql \
-v /mydata/mysql/log:/var/log/mysql \
-v /mydata/mysql/data:/var/lib/mysql \
-v /mydata/mysql/conf:/etc/mysql \
-e MYSQL_ROOT_PASSWORD=root -d mysql:5.7

• -p 3306:3306：将容器的3306端口映射到主机的3306端口
• -v /mydata/mysql/conf:/etc/mysql：将配置、日志、数据文件夹挂载到主机
• -e MYSQL_ROOT_PASSWORD=root：初始化root用户的密码
