Linux environment MySQL database with SQL statements inserted in Chinese display "question mark or garbled" problem solved!

Problem:

Under normal user permissions to execute mysql-u root-p into the MySQL database, intermediate steps omitted, insert data: INSERT into library name (attribute) values (' Kanji ');

The following prompt appears: Query OK, 1 row affected, 1 Warning (0.00 sec) indicate an error occurred, no insert succeeded, and then execute the SELECT * from table name, the following problem occurs: Garbled or question marks appear in the displayed table.

　　

Solution:

First re-open a terminal window (easy to operate), enter the root user mode

Execute VIM/VI/ETC/MYSQL/MY.CNF (this path is usually the default, depending on the individual's installation)

In the my.cnf file, modify (add) the following in the corresponding location:

[Client]
Default-character-set=utf8

[Mysqld]
Character-set-server=utf8
init_connect= ' Set names UTF8 '

Note: Do not add default-character-set=utf8 here, or the failed to start error will occur when you restart the database!!!!!

[MySQL]
Default-character-set=utf8

After the above content has been modified, save to exit.

Perform service MySQL restart restart MySQL database

Execute Mysql-u root-p (re-login here in order to avoid the problem of not modifying the document before the occurrence of garbled) re-enter the database

Execute show variables like ' character_set_% '; The following appears:

　　

Then execute INSERT into library name (attribute) values (' Kanji ') to reinsert the Chinese data, this will display the Chinese correctly!!! As shown in the following:
