linux修改mysql編碼

1. 查看mysql編碼

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     | latin1                     |
| character_set_system     | utf8                       |
| character_sets_dir       | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)

可以看到character_set_database 與character_set_server編碼格式不爲utf8

---

2. 修改編碼

• 找到mysql配置文件my.cnf，通常位於/etc/mysql或/etc目錄下,添加如下內容

[client]
default-character-set=utf8
......

[mysql]
default-character-set=utf8
......

[mysqld]
character-set-server=utf8

• 重啓mysql

service mysql restart

• 若重啓命令長時間無響應，使用Ctrl + C取消命令，並使用如下命令重啓
  

  service mysql stop
  service mysql start

---

3. 確認修改

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)
