In the debian environment, the problem that mysql cannot insert or display Chinese characters is completely solved.

How to insert Chinese characters into Mysql in Linux

Mysql-uroot-p press enter to enter the password

Enter mysql to view the status as follows:

By default, latin1 is used on the client and server, so garbled characters are displayed.

Solution:

Mysql> user mydb;

Mysql> alter database mydb character set utf8 ;!

As mentioned above, we used a temporary method to change the character set settings of the database and display Chinese characters. However, it was later found that some systems could not succeed.

For example, I used debian 7.0 and finally found a solution suitable for debian systems after a long time. the test was successful in debian 7.0, other methods, such as modifying the client and mysql to add default-character-set = utf8,Applicable only to systems earlier than 5.5!

The ultimate solution:

Modify the mysql string in debian to utf8 (refer to the "rainysia" column)

1. log on to mysql (mysql-uroot-p) and check the current database character set (status ;)

II. view the current system version (lsb_release-)

III. # vim/etc/mysql/my. cnf.(Systems earlier than 5.5)Add default-character-set = utf8 under [client]

Add default-character-set = utf8 under mysqld

Notice: If the error cannot be reported after modification, change default-character-set = utf8 to character_set_server = utf8. you do not need to add the default-character-set = utf8 parameter to the. client under mysqld.

IV. # vim/etc/mysql/my. cnf.(After December 5.5:

[Client]
Default-character-set = utf8

[Mysqld]
Default-storage-engine = INNODB
Character-set-server = utf8
Collation-server = utf8_general_ci

5. restart mysql (/etc/init. d/mysql stop/etc/init. d/mysql start)

6. after successful modification, go to mysql to view the character set (mysql> show variables like 'character _ set _ % ';)
