docker安装并运行mysql

　　docker拉取mysql之后，我们来启动它：

　　先建好本地目录，以便跟docker做映射：

[mall@VM_0_7_centos ~]$ mkdir -p mydata/mysql/{log,lib,conf}

　　再执行启动命令，使用参数进行映射：

[mall@VM_0_7_centos ~]$ sudo   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
[sudo] password for mall: 
8030a830a7b8af46fefd197e37c91cccfce867eb3593b08a64050fc90fefb98f

　　参数说明：

　　--name mysql：自定义容器名为“mysql”

　　-p 3306:3306：前者是你当前主机的3306端口，后者是当前容器中的3306端口，做了一个映射

　　-v /mydata/mysql/conf:/etc/mysql：将容器的配置文件夹/etc/mysql挂在到当前主机/mydata/mysql/conf

　　-v /mydata/mysql/log:/var/log/mysql：将容器的日志文件夹/var/log/mysql挂载到当前主机/mydata/mysql/log

　　-v /mydata/mysql/data:/var/lib/mysql/：将容器的数据文件夹/var/lib/mysql挂载到当前主机/mydata/mysql/data

　　-e MYSQL_ROOT_PASSWORD=root：初始化root用户的密码为root

　　我们进入该容器，登入mysql并创建新数据库mall：

[mall@VM_0_7_centos ~]$ sudo docker exec -it mysql /bin/bash
[sudo] password for mall: 
root@8030a830a7b8:/# mysql -uroot -proot --default-character-set=utf8

　　将sql文件上传至本地：

[mall@VM_0_7_centos ~]$ cd mydata
[mall@VM_0_7_centos mydata]$ rz -y

　　从本地复制sql文件到docker：

[mall@VM_0_7_centos ~]$ sudo docker cp mydata/mall.sql mysql:/
[sudo] password for mall: 

　　重新登入mysql，进入mall数据库，执行导入操作：

mysql> use mall;
mysql> source /mall.sql;

　　创建新账号，赋予所有权限给其他ip访问：

mysql> grant all privileges on *.* to ‘reader‘ @‘%‘ identified by ‘123456‘;
Query OK, 0 rows affected, 1 warning (0.00 sec)
