mysql5.6安裝 mysql.slave_master_info表不存在的解決方法

1.在安裝mysql 5.6.15時，安裝完成後，後臺日誌報以下警告信息：

2014-01-08 13:47:34 22946 [Warning] InnoDB: Cannot open table mysql/slave_master_info from the internal data dictionary of InnoDB though the .frm file for the table exists. See http://dev.mysql.com/doc/refman/5.6/en/innodb-troubleshooting.html for how you can resolve the problem.

2.問題產生緣由：具體緣由目前不詳，網上查找到的資料:數據庫打開這幾張表的默認引擎爲MyISAM，可是這幾張表在建表時的引擎爲INNODB

可是能肯定的，這幾張表確實是在mysql5.6中新入的

innodb_index_stats,

innodb_tables_stats,

slave_master_info,

slave_relay_log_info,

slave_worker_info

3.解決方法：

(1) 登陸數據庫，進入mysql庫，執行以下SQL刪除5張表

記住，必定要是drop table if exists

drop table if exists innodb_index_stats; drop table if exists innodb_table_stats; drop table if exists slave_master_info; drop table if exists slave_relay_log_info; drop table if exists slave_worker_info;

以下是執行的結果，忽略你看到的Warning信息

admin@localhost : mysql 02:12:26> drop table if exists innodb_index_stats;

Query OK, 0 rows affected, 1 warning (0.00 sec)

Warning (Code 155): Table 'mysql.innodb_index_stats' doesn't exist admin@localhost : mysql 02:12:26> drop table if exists innodb_table_stats; Query OK, 0 rows affected, 1 warning (0.00 sec)

Warning (Code 155): Table 'mysql.innodb_table_stats' doesn't exist admin@localhost : mysql 02:12:26> drop table if exists slave_master_info; Query OK, 0 rows affected, 1 warning (0.00 sec)

Warning (Code 155): Table 'mysql.slave_master_info' doesn't exist admin@localhost : mysql 02:12:27> drop table if exists slave_relay_log_info; Query OK, 0 rows affected, 1 warning (0.00 sec)

Warning (Code 155): Table 'mysql.slave_relay_log_info' doesn't exist admin@localhost : mysql 02:12:27> drop table if exists slave_worker_info; Query OK, 0 rows affected, 1 warning (0.00 sec) Warning (Code 155): Table 'mysql.slave_worker_info' doesn't exist

執行完後，能夠用show tables查看一下，看錶的數據是否已經比刪除以前減小了，若是減小了，說明你成功了！

(2)面這一部操做完成後，中止數據庫，並進入到數據庫數據文件所在目錄，刪除表面5個表所對應的idb文件，以下所示：

[mysql@test /data/mysqldata3/mydata/mysql]ls *.ibd innodb_index_stats.ibd innodb_table_stats.ibd slave_master_info.ibd slave_relay_log_info.ibd slave_worker_info.ibd [mysql@teset /data/mysqldata3/mydata/mysql]rm -f *.ibd

(3) 從新啓動數據庫，進入到mysql庫，重建上面被刪除的表結構：

數據庫的建設表腳本在mysql軟件的安裝目錄的share目錄下，個人mysql軟件的安裝路徑爲/usr/test/mysql

admin@localhost : (none) 02:23:03> use mysql Database changed

以下是執行建表腳本前表的數量：

admin@localhost : mysql 02:23:48> source /usr/test/mysql/share/mysql_system_tables.sql

admin@localhost : mysql 02:23:50> show tables; +---------------------------+ | Tables_in_mysql | +---------------------------+ | columns_priv | | db | | event | | func | | general_log | | help_category | | help_keyword | | help_relation | | help_topic | | ndb_binlog_index | | plugin | | proc | | procs_priv | | proxies_priv | | servers | | slow_log | | tables_priv | | time_zone | | time_zone_leap_second | | time_zone_name | | time_zone_transition | | time_zone_transition_type | | user | +---------------------------+ 23 rows in set (0.00 sec)

以下爲執行建表腳本後，表的數量

admin@localhost : mysql 02:23:46> show tables; +---------------------------+ | Tables_in_mysql | +---------------------------+ | columns_priv | | db | | event | | func | | general_log | | help_category | | help_keyword | | help_relation | | help_topic | | innodb_index_stats | | innodb_table_stats | | ndb_binlog_index | | plugin | | proc | | procs_priv | | proxies_priv | | servers | | slave_master_info | | slave_relay_log_info | | slave_worker_info | | slow_log | | tables_priv | | time_zone | | time_zone_leap_second | | time_zone_name | | time_zone_transition | | time_zone_transition_type | | user | +---------------------------+ 28 rows in set (0.00 sec)

(4) 用show create table命令查看錶時，也完正常，後臺日誌中也再也不報與上面提到的5張表相關的錯誤，到此，問題所有解決！
