《MYSQL數(shù)據(jù)庫(kù)mysql Non-Transactional Database Only(只支持MyISAM)》要點(diǎn)：

本文介紹了MYSQL數(shù)據(jù)庫(kù)mysql Non-Transactional Database Only(只支持MyISAM)，希望對(duì)您有用。如果有疑問(wèn)，可以聯(lián)系我們。

MYSQL入門(mén)后來(lái)在做WordPress,一開(kāi)始還不知道原來(lái)WordPress用的是InnoDB數(shù)據(jù)引擎,于是在原來(lái)的數(shù)據(jù)庫(kù)里面就建了一個(gè)數(shù)據(jù)庫(kù),一開(kāi)始也沒(méi)發(fā)覺(jué)問(wèn)題,安裝,導(dǎo)入sql,都沒(méi)問(wèn)題,當(dāng)時(shí)也沒(méi)多想.直到這幾天因?yàn)橛忠b多一個(gè)WordPress,用phpmyadmin訪問(wèn)數(shù)據(jù)庫(kù)多一點(diǎn),問(wèn)題來(lái)了.老是一訪問(wèn)WordPress的數(shù)據(jù)庫(kù),就彈出錯(cuò)誤提示“Mysqld-nt.exe應(yīng)用程序錯(cuò)誤：“0x005346c4”指令引用的“0x00786000”內(nèi)存,該內(nèi)存不能為讀...”,然后就MySQL服務(wù)也停了,登陸不了,整個(gè)數(shù)據(jù)庫(kù)都訪問(wèn)不了.

MYSQL入門(mén)糾結(jié)了挺久,也忘了是看到什么文章觸發(fā)了靈感,反正后來(lái)才知道原來(lái)是數(shù)據(jù)引擎不同惹的禍.于是就想到重新運(yùn)行次設(shè)置向?qū)?把數(shù)據(jù)庫(kù)類(lèi)型改成支持InnoDB引擎的.馬上行動(dòng),在向?qū)Ю镌O(shè)置數(shù)據(jù)庫(kù)類(lèi)型(也就是圖1的database usage)那里,設(shè)置成第二項(xiàng),還在后面的InnoDB Tablespace Settings里把InnoDB數(shù)據(jù)文件設(shè)置放在D:\MySQL InnoDB Datafiles目錄里.但是在最后execute執(zhí)行的時(shí)候,卻老是在Start Service那里出問(wèn)題,如下圖2.

MYSQL入門(mén)圖2 Start service出錯(cuò)

MYSQL入門(mén)想直接到services.msc里面啟動(dòng)服務(wù),也不行.錯(cuò)誤提示內(nèi)容為：“在 本地計(jì)算機(jī) 無(wú)法啟動(dòng)mysql服務(wù) 錯(cuò)誤1067：進(jìn)程意外中止.”

MYSQL入門(mén)按照網(wǎng)上的某些做法,卸載了MySQL服務(wù),也沒(méi)重啟就重新設(shè)置,問(wèn)題如故；把服務(wù)卸載了,重啟后再重新設(shè)置,則是啟動(dòng)服務(wù)成功,但是在后面的Applying Security Settings的時(shí)候有新的問(wèn)題,如下圖3.圖2那里的錯(cuò)誤提示則變成“ERROR 2003: Can't connect to MySQL server on 'localhost' (10061)", 說(shuō)明MySQL還是沒(méi)有啟動(dòng),或者啟動(dòng)過(guò),出錯(cuò)又關(guān)了.

MYSQL入門(mén)順便提一下,在MySQL5里(其他版本的我不知道)每運(yùn)行一次設(shè)置向?qū)?只要按了execute執(zhí)行,都會(huì)在MySQL5的安裝目錄下自動(dòng)生成一個(gè)原來(lái)的MySQL的設(shè)置文件my.ini的備份bak文件.并且將以修改的時(shí)間命名.因此如果設(shè)置出了問(wèn)題,可以從備份文件恢復(fù).

MYSQL入門(mén)后來(lái)還是在錯(cuò)誤日志里找到思路.錯(cuò)誤日志就是放在 MySQL5安裝目錄\Data 目錄里的那個(gè)以你的計(jì)算機(jī)名命名的.err文件.

MYSQL入門(mén)首先我找到以下一段：

MYSQL入門(mén)InnoDB: Error: log file .\ib_logfile0 is of different size 0 52428800 bytes

MYSQL入門(mén)InnoDB: than specified in the .cnf file 0 10485760 bytes!

MYSQL入門(mén)101001 9:47:42 [ERROR] Default storage engine (InnoDB) is not available

MYSQL入門(mén)101001 9:47:42 [ERROR] Aborting

MYSQL入門(mén)101001 9:47:42 [Note] D:\MySQL5\bin\mysqld-nt: Shutdown complete

MYSQL入門(mén)于是就到“MySQL5安裝目錄\Data ”目錄里把ib_logfile0日志文件刪掉,重啟MySQL服務(wù),還是提示10067錯(cuò)誤.再去查看err文件.

MYSQL入門(mén)101001 18:39:29 InnoDB: Log file .\ib_logfile0 did not exist: new to be created

MYSQL入門(mén)InnoDB: Setting log file .\ib_logfile0 size to 109 MB

MYSQL入門(mén)InnoDB: Database physically writes the file full: wait...

MYSQL入門(mén)InnoDB: Progress in MB: 100

MYSQL入門(mén)InnoDB: Error: log file .\ib_logfile1 is of different size 0 52428800 bytes

MYSQL入門(mén)InnoDB: than specified in the .cnf file 0 114294784 bytes!

MYSQL入門(mén)101001 18:39:30 [ERROR] Default storage engine (InnoDB) is not available

MYSQL入門(mén)101001 18:39:30 [ERROR] Aborting

MYSQL入門(mén)101001 18:39:30 [Note] D:\MySQL5\bin\mysqld-nt: Shutdown complete

MYSQL入門(mén)可以看到,ib_logfile0的問(wèn)題解決了,但是同樣的問(wèn)題卻出在ib_logfile1上面了.于是依樣畫(huà)葫蘆,把ib_logfile1刪了,再重啟MySQL服務(wù),卻發(fā)現(xiàn)沒(méi)用.難道是還要重啟系統(tǒng).果真,把前面兩個(gè)ib_logfile刪了,重啟系統(tǒng)就搞定了.前面的可能是因?yàn)閯傞_(kāi)機(jī),所以也行.實(shí)際上是需要重啟系統(tǒng)的.這時(shí)的日志如下

MYSQL入門(mén)101001 19:19:24 InnoDB: Log file .\ib_logfile0 did not exist: new to be created

MYSQL入門(mén)InnoDB: Setting log file .\ib_logfile0 size to 109 MB

MYSQL入門(mén)101001 19:19:26 InnoDB: Log file .\ib_logfile1 did not exist: new to be created

MYSQL入門(mén)InnoDB: Setting log file .\ib_logfile1 size to 109 MB

MYSQL入門(mén)InnoDB: Database physically writes the file full: wait...

MYSQL入門(mén)InnoDB: Progress in MB: 100

MYSQL入門(mén)InnoDB: Cannot initialize created log files because

MYSQL入門(mén)InnoDB: data files are corrupt, or new data files were

MYSQL入門(mén)InnoDB: created when the database was started previous

MYSQL入門(mén)InnoDB: time but the database was not shut down

MYSQL入門(mén)InnoDB: normally after that.

MYSQL入門(mén)101001 19:19:27 [ERROR] Default storage engine (InnoDB) is not available

MYSQL入門(mén)101001 19:19:27 [ERROR] Aborting

MYSQL入門(mén)101001 19:19:27 [Note] D:\MySQL5\bin\mysqld-nt: Shutdown complete

MYSQL入門(mén)好了,現(xiàn)在只剩下最后一個(gè)問(wèn)題了Default storage engine (InnoDB) is not available.去services.msc里面啟動(dòng)MySQL服務(wù),還是出錯(cuò).但是日志卻是顯示

MYSQL入門(mén)InnoDB: No valid checkpoint found.

MYSQL入門(mén)InnoDB: If this error appears when you are creating an InnoDB database,

MYSQL入門(mén)InnoDB: the problem may be that during an earlier attempt you managed

MYSQL入門(mén)InnoDB: to create the InnoDB data files, but log file creation failed.

MYSQL入門(mén)InnoDB: If that is the case, please refer to

MYSQL入門(mén)InnoDB: http://dev.mysql.com/doc/mysql/en/Error_creating_InnoDB.html

MYSQL入門(mén)101001 20:45:09 [ERROR] Default storage engine (InnoDB) is not available

MYSQL入門(mén)101001 20:45:09 [Note] D:\MySQL5\bin\mysqld-nt: Shutdown complete

MYSQL入門(mén)于是去網(wǎng)上搜索了一下,發(fā)現(xiàn)提示No valid checkpoint found.的解決辦法：刪除所有現(xiàn)有的ibdataN和ib_logfileN文件后,重啟Mysql.于是照做,果然行了.

MYSQL入門(mén)InnoDB: The first specified data file D:\MySQL InnoDB Datafiles\ibdata1 did not exist:

MYSQL入門(mén)奮斗了一天,總算成功地把MySQL從MyISAM轉(zhuǎn)換成InnoDB引擎了.也學(xué)會(huì)了讀懂錯(cuò)誤日志文件err文件了.不過(guò)我就在想了,如果從一開(kāi)始就按照上面的做,不知道會(huì)怎么樣呢?
