MySQL5.1: 安裝啟用InnoDB引擎
阿新 • • 發佈:2019-02-02
買的VPS伺服器,CentOS6.3,一鍵安裝的MySQL,版本5.1.61,預設引擎MyISAM,在phpmyadmin裡面找不到InnoDB引擎。
自己安裝啟用InnoDB,InnoDB外掛是隨mysql軟體包一起釋出的,設定好載入路徑即可。
編輯/etc/my.cnf檔案,在[mysqld]下面新增如下內容:
ignore-builtin-innodb
plugin-load=innodb=ha_innodb_plugin.so
plugin_dir=/usr/local/mysql-5.1.61/lib/mysql/plugin
重啟mysql服務:
/etc/init.d/mysqld restart
進入mysql命令列,執行show plugins或者show engines命令,
如果發現InnoDB沒有被載入,那麼請檢查mysql錯誤日誌(由log-error進行配置),比如:
tail -f /usr/local/mysql-5.1.61/var/my.err
出現錯誤資訊:
InnoDB: Error: log file ./ib_logfile0 is of different size 0 5242880 bytes InnoDB: than specified in the .cnf file 0 268435456 bytes! 140207 20:29:25 [ERROR] Plugin 'InnoDB' init function returned error. 140207 20:29:25 [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed.
原因是在my.cnf裡面更改了innodb_log_file_size變數的數值,如無必要修改,去掉重啟:
mysql> show plugins; +------------+--------+----------------+---------------------+---------+ | Name | Status | Type | Library | License | +------------+--------+----------------+---------------------+---------+ | binlog | ACTIVE | STORAGE ENGINE | NULL | GPL | | CSV | ACTIVE | STORAGE ENGINE | NULL | GPL | | MEMORY | ACTIVE | STORAGE ENGINE | NULL | GPL | | MyISAM | ACTIVE | STORAGE ENGINE | NULL | GPL | | MRG_MYISAM | ACTIVE | STORAGE ENGINE | NULL | GPL | | InnoDB | ACTIVE | STORAGE ENGINE | ha_innodb_plugin.so | GPL | +------------+--------+----------------+---------------------+---------+
