1.拉取镜像

docker pull mysql:5.7

2.查看本地镜像

docker images

3.创建目录

mkdir /usr/local/docker/mysql/logs

mkdir /usr/local/docker/mysql/data

mkdir /usr/local/docker/mysql/conf

4.创建my.cnf文件，内容如下

[mysql]

#设置mysql客户端默认字符集

default-character-set=utf8

socket=/var/lib/mysql/mysql.sock

[mysqld]

#mysql5.7以后的不兼容问题处理

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

datadir=/var/lib/mysql

socket=/var/lib/mysql/mysql.sock

# Disabling symbolic-links is recommended to prevent assorted security risks

symbolic-links=0

# Settings user and group are ignored when systemd is used.

# If you need to run mysqld under a different user or group,

# customize your systemd unit file for mariadb according to the

# instructions in http://fedoraproject.org/wiki/Systemd

#允许最大连接数

max_connections=200

#服务端使用的字符集默认为8比特编码的latin1字符集

character-set-server=utf8

#创建新表时将使用的默认存储引擎

default-storage-engine=INNODB

lower_case_table_names=1

max_allowed_packet=16M 

#设置时区

default-time_zone='+8:00'

[mysqld_safe]

log-error=/var/log/mariadb/mariadb.log

pid-file=/var/run/mariadb/mariadb.pid

#

# include all files from the config directory

#

!includedir /etc/mysql/conf.d/

!includedir /etc/mysql/mysql.conf.d/

5.启动容器

docker run --name mysql5.7 -p 3306:3306 --privileged=true --restart=always -d -v /usr/local/docker/mysql/logs:/logs -v /usr/local/docker/mysql/data:/var/lib/mysql -v  /usr/local/docker/mysql/conf/my.cnf:/etc/mysql/mysql.conf.d/mysqld.cnf -e MYSQL_ROOT_PASSWORD=Cc201818 mysql:5.7

6.查看容器启动状态

docker ps -a

7.测试连接

通过可视化工具进行连接即可
