docker啟動mysql

想要安裝一個mysql服務實例，最簡單的方式當然是用docker啟動一個
只需一個命令搞定：

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

其中： –name 後面的是docker容器名 -e MYSQL_ROOT_PASSWORD 是設置mysql的root賬號密碼 -d mysql 是你的鏡像標簽
還可以加上 -v

 #先創建目錄和my.cf配置文件
 #mkdir -p /home/mysql/{conf,logs,data/mysql}




 -v /home/mysql/conf/my.cnf:/etc/mysql/my.cnf -v /home/mysql/logs:/logs -v /home/mysql/data/mysql:/var/lib/mysql

用來掛載數據目錄、配置文件、日志等 這樣重啟實例後數據不會丟失
如果連接Docker啟動的mysql出現報錯： ERROR 2059 (HY000): Authentication plugin ‘caching_sha2_password’ cannot be loaded 解決辦法，重新設置下密碼：

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '12345678';

啟動成功後：

[root@iZttsn6fen661yZ ~]# docker ps
