centos 修改 mysql 字符集

客户提供了 mysql 的环境，但是不支持中文，通过以下命令查看了 mysql 的字符集

mysql> show variables like 'character_set%';

显示如下：

+--------------------------+----------------------------+  | 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/ |  +--------------------------+----------------------------+

为了让 mysql 支持中文，需要把字符集改变成 utf8 。

方法如下：

1. 打开 etc/my.cnf

2. 修改成如下内容，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. 重启 mysql 服务

service mysqld restart

再次查看 mysql 编码，已经更新成如下信息

+--------------------------+----------------------------+  | 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/ |  +--------------------------+----------------------------+
