解決思路：mysql
1. 在MySQL安裝目錄下執行./mysql_upgrade -uroot -p,此處是爲了更新MySQL的系統表，在5.6以前的版本上，更新系統表的命令是mysql_fix_privilege_tables（注意MySQL版本);sql
2.運行完以後重啓mysql服務spa
service mysqld restartrest
若是以上沒法解決則採用以下解決方式：code
進入mysql庫內，執行如下sql語句：
io
mysql>DROP TABLE IF EXISTS `event`;event
mysql>CREATE TABLE `event` (table
`db` char(64) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL DEFAULT '', `name` char(64) NOT NULL DEFAULT '', `body` longblob NOT NULL, `definer` char(77) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL DEFAULT '', `execute_at` datetime DEFAULT NULL, `interval_value` int(11) DEFAULT NULL, `interval_field` enum('YEAR','QUARTER','MONTH','DAY','HOUR','MINUTE','WEEK','SECOND','MICROSECOND','YEAR_MONTH','DAY_HOUR','DAY_MINUTE','DAY_SECOND','HOUR_MINUTE','HOUR_SECOND','MINUTE_SECOND','DAY_MICROSECOND','HOUR_MICROSECOND','MINUTE_MICROSECOND','SECOND_MICROSECOND') DEFAULT NULL, `created` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, `modified` timestamp NOT NULL DEFAULT '0000-00-00 00:00:00', `last_executed` datetime DEFAULT NULL, `starts` datetime DEFAULT NULL, `ends` datetime DEFAULT NULL, `status` enum('ENABLED','DISABLED','SLAVESIDE_DISABLED') NOT NULL DEFAULT 'ENABLED', `on_completion` enum('DROP','PRESERVE') NOT NULL DEFAULT 'DROP', `sql_mode` set('REAL_AS_FLOAT','PIPES_AS_CONCAT','ANSI_QUOTES','IGNORE_SPACE','NOT_USED','ONLY_FULL_GROUP_BY','NO_UNSIGNED_SUBTRACTION','NO_DIR_IN_CREATE','POSTGRESQL','ORACLE','MSSQL','DB2','MAXDB','NO_KEY_OPTIONS','NO_TABLE_OPTIONS','NO_FIELD_OPTIONS','MYSQL323','MYSQL40','ANSI','NO_AUTO_VALUE_ON_ZERO','NO_BACKSLASH_ESCAPES','STRICT_TRANS_TABLES','STRICT_ALL_TABLES','NO_ZERO_IN_DATE','NO_ZERO_DATE','INVALID_DATES','ERROR_FOR_DIVISION_BY_ZERO','TRADITIONAL','NO_AUTO_CREATE_USER','HIGH_NOT_PRECEDENCE','NO_ENGINE_SUBSTITUTION','PAD_CHAR_TO_FULL_LENGTH') NOT NULL DEFAULT '', `comment` char(64) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL DEFAULT '', `originator` int(10) unsigned NOT NULL, `time_zone` char(64) CHARACTER SET latin1 NOT NULL DEFAULT 'SYSTEM', `character_set_client` char(32) CHARACTER SET utf8 COLLATE utf8_bin DEFAULT NULL, `collation_connection` char(32) CHARACTER SET utf8 COLLATE utf8_bin DEFAULT NULL, `db_collation` char(32) CHARACTER SET utf8 COLLATE utf8_bin DEFAULT NULL, `body_utf8` longblob, PRIMARY KEY (`db`,`name`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 COMMENT='Events';而後在重啓MySQL服務便可解決！
