标签：-- 客户 comm 改变 显示 dir variable usr log-error
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
连接上 mysql 服务，输入以下命令
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/ | +--------------------------+----------------------------+
