mysql庫編碼修改，庫默認的編碼為拉丁文，我創建的agilefant庫編碼也就是拉丁文的 不支持中文。整個操作過程切記務必先備份庫再操作。mysql> show variables like 'collation_%';+----------------------+-------------------+| Variable_name | Value |+----------------------+-------------------+| collation_connection | latin1_swedish_ci || collation_database | latin1_swedish_ci || collation_server | latin1_swedish_ci |+----------------------+-------------------+首先vi /etc/my.cnf[client]#password = your_passwordport = 3306socket = /tmp/mysql.sockdefault-character-set=utf8# Here follows entries for some specific programs# The MySQL server[mysqld]port = 3306socket = /tmp/mysql.sockdatadir = /wwwroot/mysqldefault-character-set=utf8skip-name-resolvedefault-character-set=utf8(這句)再次：mysql> show variables like 'collation_%';ERROR 2006 (HY000): MySQL server has gone awayNo connection.
