首页 / 数据库 / MySQL / MySQL innodb_table_stats表不存在的解决方法
MySQL 版本 5.6.14公司有几台MySQL服务器的错误日志显示,有几个系统表不存在. innodb_table_stats innodb_index_stats slave_master_info slave_relay_log_info slave_worker_info这是因为数据库初始化的时候,dba可能删除过ibdata1文件 虽然重启之后,数据库会自动创建一个ibdata1文件,但是上述系统表也是innodb引擎,所以不能访问了. 这虽然不会影响业务,但是使用innobackupex备份的时候,会写入错误日志. 最后错误日志里,都是这种信息.影响日常检查。 解决的方法. 1.删除上述系统表 drop table mysql.innodb_index_stats; drop table mysql.innodb_table_stats; drop table mysql.slave_master_info; drop table mysql.slave_relay_log_info; drop table mysql.slave_worker_info; 2.删除相关的.frm .ibd文件 rm -rf innodb_index_stats* rm -rf innodb_table_stats* rm -rf slave_master_info* rm -rf slave_relay_log_info* rm -rf slave_worker_info* 3.重新创建上述系统表 CREATE TABLE `innodb_index_stats` ( `database_name` varchar(64) COLLATE utf8_bin NOT NULL, `table_name` varchar(64) COLLATE utf8_bin NOT NULL, `index_name` varchar(64) COLLATE utf8_bin NOT NULL, `last_update` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, `stat_name` varchar(64) COLLATE utf8_bin NOT NULL, `stat_value` bigint(20) unsigned NOT NULL, `sample_size` bigint(20) unsigned DEFAULT NULL, `stat_description` varchar(1024) COLLATE utf8_bin NOT NULL, PRIMARY KEY (`database_name`,`table_name`,`index_name`,`stat_name`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin STATS_PERSISTENT=0; CREATE TABLE `innodb_table_stats` ( `database_name` varchar(64) COLLATE utf8_bin NOT NULL, `table_name` varchar(64) COLLATE utf8_bin NOT NULL, `last_update` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, `n_rows` bigint(20) unsigned NOT NULL, `clustered_index_size` bigint(20) unsigned NOT NULL, `sum_of_other_index_sizes` bigint(20) unsigned NOT NULL, PRIMARY KEY (`database_name`,`table_name`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin STATS_PERSISTENT=0; CREATE TABLE `slave_master_info` ( `Number_of_lines` int(10) unsigned NOT NULL COMMENT "Number of lines in the file.", `Master_log_name` text CHARACTER SET utf8 COLLATE utf8_bin NOT NULL COMMENT "The name of the master binary log currently being read from the master.", `Master_log_pos` bigint(20) unsigned NOT NULL COMMENT "The master log position of the last read event.", `Host` char(64) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL DEFAULT "" COMMENT "The host name of the master.", `User_name` text CHARACTER SET utf8 COLLATE utf8_bin COMMENT "The user name used to connect to the master.", `User_password` text CHARACTER SET utf8 COLLATE utf8_bin COMMENT "The password used to connect to the master.", `Port` int(10) unsigned NOT NULL COMMENT "The network port used to connect to the master.", `Connect_retry` int(10) unsigned NOT NULL COMMENT "The period (in seconds) that the slave will wait before trying to reconnect to the master.", `Enabled_ssl` tinyint(1) NOT NULL COMMENT "Indicates whether the server supports SSL connections.", `Ssl_ca` text CHARACTER SET utf8 COLLATE utf8_bin COMMENT "The file used for the Certificate Authority (CA) certificate.", `Ssl_capath` text CHARACTER SET utf8 COLLATE utf8_bin COMMENT "The path to the Certificate Authority (CA) certificates.", `Ssl_cert` text CHARACTER SET utf8 COLLATE utf8_bin COMMENT "The name of the SSL certificate file.", `Ssl_cipher` text CHARACTER SET utf8 COLLATE utf8_bin COMMENT "The name of the cipher in use for the SSL connection.", `Ssl_key` text CHARACTER SET utf8 COLLATE utf8_bin COMMENT "The name of the SSL key file.", `Ssl_verify_server_cert` tinyint(1) NOT NULL COMMENT "Whether to verify the server certificate.", `Heartbeat` float NOT NULL, `Bind` text CHARACTER SET utf8 COLLATE utf8_bin COMMENT "Displays which interface is employed when connecting to the MySQL server", `Ignored_server_ids` text CHARACTER SET utf8 COLLATE utf8_bin COMMENT "The number of server IDs to be ignored, followed by the actual server IDs", `Uuid` text CHARACTER SET utf8 COLLATE utf8_bin COMMENT "The master server uuid.", `Retry_count` bigint(20) unsigned NOT NULL COMMENT "Number of reconnect attempts, to the master, before giving up.", `Ssl_crl` text CHARACTER SET utf8 COLLATE utf8_bin COMMENT "The file used for the Certificate Revocation List (CRL)", `Ssl_crlpath` text CHARACTER SET utf8 COLLATE utf8_bin COMMENT "The path used for Certificate Revocation List (CRL) files", `Enabled_auto_position` tinyint(1) NOT NULL COMMENT "Indicates whether GTIDs will be used to retrieve events from the master.", PRIMARY KEY (`Host`,`Port`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 STATS_PERSISTENT=0 COMMENT="Master Information"; CREATE TABLE `slave_relay_log_info` ( `Number_of_lines` int(10) unsigned NOT NULL COMMENT "Number of lines in the file or rows in the table.
