查看MySQL數據庫當前設置的字符集
mysql> SHOW VARIABLES LIKE 'character%';
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | latin1 |
| character_set_connection | latin1 |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | latin1 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)
2.臨時更改MySQL數據庫的字符集
mysql> SET character_set_client = utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> SET character_set_connection = utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> SET character_set_results = utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> SET character_set_server = utf8;
Query OK, 0 rows affected (0.00 sec)
3.查看數據庫字符集是否更改成功
mysql> SHOW VARIABLES LIKE 'character%';
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)
4.重啓mysql服務器
[root@localhost ~]# service mysqld restart
Stopping mysqld: [ OK ]
Starting mysqld: [ OK ]
5.查看MySQL字符集
mysql> SHOW VARIABLES LIKE 'character%';
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | latin1 |
| character_set_connection | latin1 |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | latin1 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)
6.永久修改MySQL字符集
[root@localhost ~]# vim /etc/my.cnf
[mysqld]
..............
default-character-set=utf8
[client]
default-character-set=utf8
[mysql]
default-character-set=utf8
7.重新啓動MySQL數據庫
[root@localhost ~]# service mysqld restart
Stopping mysqld: [ OK ]
Starting mysqld: [ OK ]
7.再次查看MySQL字符集設置是否生效
mysql> SHOW VARIABLES LIKE 'character%';
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)
