使用Docker配置Mysql

• 1.下載MySQL

docker pull mysql:5.7

• 2.使用docker執行mysql

docker run -d -e MYSQL_ROOT_PASSWORD=123456 -p 3306:3306 mysql:5.7

• 3.配置MySQL四步曲

進入容器內:docker exec -it 容器ID
進入到MySQL:mysql -uroot "username" -p "password"
允許名為root的使用者遠端連結:GRANT ALL ON . TO 'root'@'%'
或允許名為root密碼為1-6的使用者遠端連線、root後的@可以跟你本機的ip地址，不指定為所有：grant all privileges on .

to 'root'@'%' identified by '123456' with grant option;
修改加密規則:ALTER USER 'root'@'%' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER;
更改root密碼:ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';
重新整理許可權:flush privileges;
檢視使用者資訊:
select host,user,plugin,authentication_string from mysql.user;
或者摺合
docker run -d -p 3336:3306 -v /home/mysql/conf:/etc/mysql/conf.d -v /home/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=root123 --name mysql01 mysql:5.7

[root@xiaozhang1999 ~]# docker run -d -p 3336:3306 -v /home/mysql/conf:/etc/mysql/conf.d -v /home/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=root123 --name mysql01 mysql:5.7

• 4.啟動成功之後在本地Native驗證持久化

• 5.在本地新建個數據庫後去Liunx下檢視

• 注意:防火牆埠設定

VM虛擬機器下：
檢視firewalld狀態，如果防火牆未工作則需要先開啟。
systemctl status firewalld//檢視狀態
systemctl start firewalld//開啟
開啟firewalld後，設定開放埠
// --permanent 永久生效,沒有此引數重啟後失效
firewall-cmd --zone=public --add-port=3306/tcp --permanent
之後重新載入設定
systemctl start firewalld
使用如下命令檢視3306號埠
firewall-cmd --zone=public --query-port=3306/tcp
阿里雲伺服器下:安全組設定配置上述用到的開放埠
