docker中創建MySQL及在外部使用Navicat連接

 

1：獲取MySQL鏡像

運行 docker pull mysql

[root@MyCentos7-1 ~]# docker pull mysql  
Using default tag: latest  
latest: Pulling from library/mysql  
85b1f47fba49: Pull complete   
5671503d4f93: Pull complete   
3b43b3b913cb: Pull complete   
4fbb803665d0: Pull complete

Status: Downloaded newer image for mysql:latest  

2：啟動MySQL鏡像

[root@MyCentos7-1 ~]# docker run --name=mysql -itd -p 3306:3306 -e MYSQL_ROOT_PASSWORD=abcd123 mysql  
eb3dbfb0958f5c856323e4d8da60d43194884ff05d7adac1ec059adb66ac7f7b  

docker run是啟動容器的命令；

--name：指定了容器的名稱，方便之后進入容器的命令行

-itd：其中，i是交互式操作，t是一個終端，d指的是在后台運行

-p：指在本地生成一個隨機端口，用來映射mysql的3306端口

-e：設置環境變量

MYSQL_ROOT_PASSWORD=emc123123：指定了mysql的root密碼

mysql：指運行mysql鏡像

3：進入MySQL容器

運行  docker exec -it mysql /bin/bash

[root@MyCentos7-1 ~]# docker exec -it mysql /bin/bash
root@my-mysql-v1-nths4:/usr/local/mysql# 

4：進入MySQL

運行  mysql -uroot -p

root@my-mysql-v1-nths4:/usr/local/mysql# mysql -uroot -p 
Enter password:

5：進行配置，使外部工具可以連接

為了安全，首先需要設置root帳號的密碼

mysql> update user set authentication_string = password('root') where user = 'root';

將root的密碼改為root。 
接着，由於mysql中root執行綁定在了localhost，因此需要對root進行授權，代碼如下，

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;

最后，使用navitecat測試mysql連接，如下，
