在Docker上面安装/启动、运行、挂载MySQL5.7

下载文档请看：https://hub.docker.com/r/mysql/mysql-server

一.下载镜像

执行命令： docker pull mysql/mysql-server:5.7

查看命令：docker images

运行MySQL后台运行并映射到本地端口命令：docker run -d -p 3306:3306 --name mysql mysql/mysql-server:5.7

查看运行容器：docker ps

监视容器的输出：docker logs mysql

连接到mysql server命令：docker exec -it mysql mysql -uroot -p

密码为：docker logs mysql 里面输出password后面的内容

重置mysql服务的密码：ALTER USER 'root'@'localhost' IDENTIFIED BY 'password'

创建用户并且赋权限： create user '用户名'@'%' identified by '密码';

grant all privileges on *.* to '用户名'@'%' with grant option;

三.设置字符集编码格式

进入 容器： docker exec -it mysql bash

cd /etc

安装vim编辑器 :yum install vim

进入mysql配置文件：vim my.cnf

编写后的内容

[client]
#password       = your_password
port               = 3306
socket          = /data0/data/mysql.sock
default-character-set = utf8mb4

[mysql]  
default-character-set = utf8mb4

[mysqld]  
character-set-client-handshake = FALSE
character-set-server = utf8mb4
collation-server = utf8mb4_general_ci
init_connect = 'SET NAMES utf8mb4'

port            = 3306
socket          = /data0/data/mysql.sock
skip-external-locking
key_buffer_size = 16M
max_allowed_packet = 1M
table_open_cache = 64
sort_buffer_size = 512K
net_buffer_length = 8K
read_buffer_size = 256K
read_rnd_buffer_size = 512K
myisam_sort_buffer_size = 8M
datadir = /data0/data

[mysqldump]
quick
max_allowed_packet = 16M

[mysql]
no-auto-rehash

[myisamchk]
key_buffer_size = 20M
sort_buffer_size = 20M
read_buffer = 2M
write_buffer = 2M

[mysqlhotcopy]
interactive-timeout　　

也可以通过运行容器时来配置参数：

命令如下

docker run -d -p 3306:3306  -e MYSQL_USER="用户名" -e MYSQL_PASSWORD="密码" -e MYSQL_ROOT_PASSWORD="密码" --name mysql mysql/mysql-server:5.7 --character-set-server=utf8 --collation-server=utf8_general_ci

个人建议 直接通过运行容器来配置参数
