【Mysql】CentOS 環境下mysql 數據庫字符編碼設置

mysql 默認字符編碼多是Latin文，在存入和取出的時候回出現亂碼的問題，因此須要給數據庫從新編碼

經過如下命令 查看mysql的字符集

mysql>show variables like 'character_set%';
顯示：
+--------------------------+----------------------------+
| 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/ |
+--------------------------+----------------------------+

爲了讓mysq再也不出現亂碼，須要把字符集編碼改成 UTF-8

方法以下：

1.打開 etc/my.cnf

2.修改爲以下內容，保存

[client]
port=3306
socket=/var/lib/mysql/mysql.sock
default-character-set=utf8

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
character-set-server=utf8

[mysql]
no-auto-rehash
default-character-set=utf8

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

3.重啓mysql服務：service mysqld restart

再次查看mysql編碼，已經更新。
