下载MySQL镜像

#获取最新的镜像
docker pull mysql
#获取指定版本
docker pull mysql:8.0.16

2、查看下载的mysql镜像

docker images mysql

3、宿主机创建目录及配置文件

在/data中建立MySQL的data、config、log目录，在config目录中创建MySQL配置文件my.cnf，内容如下

#
# The MySQL  Server configuration file.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

[mysqld]
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
datadir         = /var/lib/mysql
secure-file-priv= NULL
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

# Custom config should go here
!includedir /etc/mysql/conf.d/

default_authentication_plugin= mysql_native_password

4、启动MySQL实例

启动一个实例名为scloud_mysql的MySQL容器，端口号为3306，root用户密码为root

docker run \
    -p 3306:3306 \
    -e MYSQL_ROOT_PASSWORD=root \
    -v /data/mysql/data/scloud_mysql:/var/lib/mysql:rw \
    -v /data/mysql/log/scloud_mysql:/var/log/mysql:rw \
    -v /data/mysql/config/scloud_mysql/my.cnf:/etc/mysql/my.cnf:rw \
    -v /etc/localtime:/etc/localtime:ro \
    --name scloud_mysql \
    --restart=always \
    -d mysql

5、iptables增加端口3306端口放行

iptables -I INPUT 1 -p tcp --dport 3306 -j ACCEPT -m comment --comment "scloud mysql port"
service iptables save
systemctl restart iptables
iptables -L -n -v
