1 下載鏡像
[root@node-11 ~]# docker pull mysql:5.7.20
2 創建mysql目錄
[root@node-11 ~]# mkdir /opt/mysql/{data,conf,logs} -p
目錄說明：
data：數據目錄
conf：配置文件
logs：日志目錄
3 編輯配置文件
[root@node-11 ~]# vim /opt/mysql/conf/mysqld.cnf
[mysqld]
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
datadir = /var/lib/mysql
lower_case_table_names = 1 ## 忽略mysql查詢大小寫
注意：這只是簡單的mysql參數，具體的參數需要根據業務需求，自行添加即可，這里需要注意的是，涉及到mysql數據目錄的話，一定要寫容器內的路徑，而不是映射到宿主機的目錄。
4 啟動
[root@node-11 ~]# docker run -d -p 3306:3306 --name mysql \
-v /opt/mysql/data:/var/lib/mysql \
-v /opt/mysql/logs:/var/log/mysql \
-v /opt/mysql/conf:/etc/mysql/mysql.conf.d \
-e MYSQL_ROOT_PASSWORD=123456 mysql:5.7.20
參數解釋：
- --name: 容器名稱
- -p 3306: 映射端口
- MYSQL_ROOT_PASSWORD：mysql初始密碼
- -v冒號前面是宿主機目錄，后面是容器目錄
