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

登录：

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 |+-----------+------------------+-----------------------+------------------------------------------------------------------------+5 rows in set (0.00 sec)

刷新配置

flush privileges;

四，阿里云记得开放3307端口

防火墙中添加规则
