1. MySQL 容器搭建

• 更新 yum 镜像源，下载 docker 的阿里镜像源：
  [root@bogon ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
• 安装 docker 所需的依赖包:
  [root@bogon ~]# yum -y install yum-utils device-mapper-persistent-data lvm2 container-selinux
• 添加 docker 的阿里源
  [root@bogon ~]# yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
• 启动 docker

[root@bogon ~]# yum install docker -y

• 安装阿里云加速器
  登录自己的阿里云账号进入一下页面即可复制专属加速器地址

https://cr.console.aliyun.com/#/accelerator

sudo mkdir -p /etc/docker

sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://vtbf99sa.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

• 拉取所需镜像

[root@bogon ~]# docker pull nginx:latest 
[root@bogon ~]# docker pull mysql:8 
[root@bogon ~]# docker pull bitnami/php-fpm

• 创建文件夹

[root@bogon ~]# mkdir -pv /docker/www     #网站根目录

mkdir: 已创建目录 "/docker"
mkdir: 已创建目录 "/docker/www"
[root@bogon ~]# mkdir -pv /docker/nginx/conf.d/
      #nginx配置文件
mkdir: 已创建目录 "/docker/nginx"
mkdir: 已创建目录 "/docker/nginx/conf.d/"
[root@bogon ~]# mkdir -pv /docker/mysql 
mkdir: 已创建目录 "/docker/mysql"
    #数据库文件夹
[root@bogon ~]#

• 构建 MySQL 容器

[root@bogon ~]# docker run -d -p 3306:3306 -e MYSQL_ROOT_PASSWORD=598941324 -v /docker/mysql:/var/lib/mysql --name mysql8 mysql:8

528438949af0625fd7a936c49768d953c238f2d633614d2ef9cca74b9254843c
[root@bogon ~]# docker exec -it mysql8 /bin/bash 

root@528438949af0:/# mysql -uroot -p598941324

• 在宿主机上测试是否能连接 MySQL 容器

[root@bogon ~]# 

[root@bogon ~]# docker inspect mysql8 --format='{{.NetworkSettings.IPAddress}}'
    #查看数据库ip
172.17.0.2
[root@bogon ~]# 
[root@bogon ~]# mysql -h172.17.0.2 -uroot -p598941324
      #重置密码
