Detailed explanation of Mac environment mysql5.7.21 utf8 encoding problem

This article mainly introduces to you the Mac environment mysql5.7.21 utf8 encoding problems and solutions. I hope it can help you.

1. Goal: Change the value of mysql's character_set_server from latin1 to utf8

Temporarily: SET character_set_server=utf8 is enough, one-time.

Permanent: The configuration file needs to be changed, see step 2.

2. There is no configuration file in the support-files of mysql 5.7.21.

Create new my.cnf. You can create a text file and directly change the extension to cnf. It is better to open it with Xcode or subline. The content is as follows:

[mysqld] character-set-server=utf8 [client] default-character-set=utf8 [mysql] default-character-set=utf8

3. Copy my.cnf to /private/etc/

cp /usr/local/mysql/support-files/my.cnf /private/etc/my.cnf

Note: In fact, /etc is a stand-in for /private/etc, and can be copied to both.

4. Restart the mysql server and enter mysql
