远程连接docker部署的mysql

最近在帮一个朋友弄挑战杯的后端，学校也赞助了我们服务器，就利用这个机会看看项目部署上的一些要点

本文主要介绍关于对docker部署的mysql的一个远程连接

1. docker拉取mysql镜像

docker pull mysql

2.拉取完后运行mysql容器

docker run --name mysql -p 3305:3306 -e MYSQL_ROOT_PASSWORD=123 -d mysql

解释下：

--name :后面是这个镜像的名称
3307:3306：表示在这个容器中使用3307端口(第二个)映射到本机的端口号也为3306(第一个)
-d :后台运行
-e MYSQL_ROOT_PASSWORD=123：设置root初始密码

3.进入到mysql容器内部

docker exec -it mysql bash

mysql -uroot -p123

查看用户信息：

mysql> select host,user,plugin,authentication_string from mysql.user; 
+-----------+------------------+-----------------------+------------------------------------------------------------------------+
| host      | user             | plugin                | authentication_string                                                  |
+-----------+------------------+-----------------------+------------------------------------------------------------------------+
| %         | root             | caching_sha2_password | $A$005$HF7;krfwhkKHp5fPenQm4J2dm/RJtbbyjtCUVdDCcboXQw3ALxsif/sS1 |
| localhost | mysql.infoschema | caching_sha2_password | $A$005$THISISACOMBINATIONOFINVALIDSALTANDPASSWORDTHATMUSTNEVERBRBEUSED |
| localhost | mysql.session    | caching_sha2_password | $A$005$THISISACOMBINATIONOFINVALIDSALTANDPASSWORDTHATMUSTNEVERBRBEUSED |
| localhost | mysql.sys        | caching_sha2_password | $A$005$THISISACOMBINATIONOFINVALIDSALTANDPASSWORDTHATMUSTNEVERBRBEUSED |
| localhost | root             | mysql_native_password | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9                              |
+-----------+------------------+-----------------------+------------------------------------------------------------------------+

备注：host为 % 表示不限制ip localhost表示本机使用 plugin非mysql_native_password 则需要修改密码

修改加密方式：

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';  ### 123456 mysql的登录密码
flush privileges;

在查看用户信息

mysql> select host,user,plugin,authentication_string from mysql.user;
+-----------+------------------+-----------------------+------------------------------------------------------------------------+
| host      | user             | plugin                | authentication_string                                                  |
+-----------+------------------+-----------------------+------------------------------------------------------------------------+
| %         | root             | mysql_native_password | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9                              |
| localhost | mysql.infoschema | caching_sha2_password | $A$005$THISISACOMBINATIONOFINVALIDSALTANDPASSWORDTHATMUSTNEVERBRBEUSED |
| localhost | mysql.session    | caching_sha2_password | $A$005$THISISACOMBINATIONOFINVALIDSALTANDPASSWORDTHATMUSTNEVERBRBEUSED |
| localhost | mysql.sys        | caching_sha2_password | $A$005$THISISACOMBINATIONOFINVALIDSALTANDPASSWORDTHATMUSTNEVERBRBEUSED |
| localhost | root             | mysql_native_password | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9                              |
