//目前最新的為mysql 8

sudo docker run -itd --restart unless-stopped --net=host --name mysql -p3306:3306 -e MYSQL_ROOT_PASSWORD=root mysql

mysql 官方docker 需要重新設(shè)置密碼，否則無法遠(yuǎn)程連接

step1 : docker exec -it [容器id] /bin/bash

step2 : 登陸mysql ==> mysql -uroot -h localhost -proot>use mysql;

mysql>ALTER USER'root'@'%' IDENTIFIED WITH mysql_native_password BY 'newpassword'

常用的mysql5.7：

sudo docker run -it -d --restart unless-stopped -p 13306:3306 -h mysql --name mysql -e MYSQL_ROOT_PASSWORD=root 　alanpeng/mysql5.7-replication-docker

sudo docker run -itd --restart unless-stopped -p 3306:3306 --net=host -h mysql --name mysql -e MYSQL_ROOT_PASSWORD=root alanpeng/mysql5.7-replication-docker

修改：

(如果不是在docker中 vi /etc/mysql/my.cnf)

vi? ?/etc/mysql/mysql.conf.d/mysqld.cnf

cd?? /etc/mysql/mysql.conf.d

echo 'sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION' >> mysqld.cnf

echo 'explicit_defaults_for_timestamp = 1' >>mysqld.cnf

echo 'max_allowed_packet= 500M' >>mysqld.cnf

mysql -uroot -p000000

1)展示user表的結(jié)構(gòu)

mysql>desc user;

2)查詢user表

mysql>select?User, Host, Password from user;

3)修改user表，把Host表內(nèi)容修改為%

mysql>update user set host='%' where user='root' and host='localhost';

4)刪除root用戶的其他host

mysql>delete from user where User='root'and Host='hadoop001 ';

mysql>delete from user where User='root'and Host='127.0.0.1';

mysql>delete from user where User='root'and Host='::1';

6)刷新

mysql>flush privileges;
