Execute the mysql script file in the docker mysql container and solve the garbled characters

docker 容器中执行mysqlscript files and resolve garbled characters

Searched a lot online,在容器mysqlIs it so hard to execute a piece of code in ？Make it very complicated. So record it yourself,虽然简单,But still afraid of forgetting it later,Search for a long time.

The need now is to be minesql文件导入进来,然后让docker中的mysql 来执行它.

注意mysql在docker容器中,If you only import to the host machine,Then enter the container to executesql文件的话,It will tell you that it cannot be opened,Because the outside of the host and the inside of the container are relatively isolated,It is impossible to find the path of the host inside the container.

因此,All we have to do is put the host machinesqlThe file is copied inside the container,Then let it execute,这样就好了. 我把sqlfiles are placed here,Here is what I used to do anddocker sqlOrdinary directory for file mounts,当然,You can put it anywhere now.

To copy to the inside of the container,You need to find the container first. 首先列举出来,Take a look at running containers,对应mysql的id就知道了.

docker ps

复制

然后我们通过id to specify the container,这个也就是mysql容器的id We can enter the container with this command,We go in here,You can log in heremysql,然后执行脚本.

 docker exec -it 4f50fbeb15ee /bin/bash

复制

ctrl+d,退出容器 但是在这之前,我们要将sql文件拷贝进来.

docker cp /mysql/mysql/1.sql   4f50fbeb15ee:/home/1.sql

复制

cpThe back is your host computersql文件所在的路径,容器idThe latter one is the containerhome文件夹,One is named after I copied itsql文件.Copy here.

after copying,We go into the container again.

 docker exec -it 4f50fbeb15ee /bin/bash

复制

Then we go into the containerhome

cd home

复制

Check to see if there is one in the directory1.sql,View inside the container is not availablell,所以用ls

ls

复制

有的 在容器中执行,Just use the path in the container,It has nothing to do with the host path. 然后我们就执行

source /home/1.sql

复制

但是有的时候啊,执行完毕后,He will have some gibberish.

So we can try to look at some encodings

 show variables like '%char%';

复制

I changed all these encodings to utf-8

set character_set_client=utf8;
set character_set_connection=utf8;
set character_set_database=utf8;
set character_set_results=utf8;
set character_set_server=utf8;

复制

这样做是有效的,Later, the fields with garbled characters in my database were all normal.
