故障：今天在維護(hù)以前數(shù)據(jù)庫(kù)日志的時(shí)候，把目錄下所有的日志都?jí)嚎s拷貝到本地了以防以后查詢使用，壓縮之后清理了日志目錄下/var/log/mysqllog所有的日志，然后重啟服務(wù)

/etc/init.d/mysqld restart

[root@localhost ~]# /etc/init.d/mysqld start MySQL Daemon failed to start. 正在啟動(dòng) mysqld： [失敗]

查看日志，

[root@localhost ~]# tailf /var/log/mysqld.log 140226 10:58:40 [ERROR] Failed to open log (file '/var/log/mysqllog/myupdate.000050', errno 2) 140226 10:58:40 [ERROR] Could not open log file 140226 10:58:40 [ERROR] Can't init tc log 140226 10:58:40 [ERROR] Aborting140226 10:58:40 InnoDB: Starting shutdown... 140226 10:58:45 InnoDB: Shutdown completed; log sequence number 0 168021 140226 10:58:45 [Note] /usr/libexec/mysqld: Shutdown complete140226 10:58:45 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended

?這個(gè)文件已經(jīng)被我刪除/var/log/mysqllog/myupdate.000050，是更新日志最后一個(gè)文件，所以mysql找不到這個(gè)文件，應(yīng)該是還準(zhǔn)備往這個(gè)文件里面寫日志，所以我想是不是有什么命令應(yīng)該可以讓mysql更新日志重新滾動(dòng)呢，在網(wǎng)上找了好久沒找到，最后看見了在目錄下面myupdate.index 這個(gè)文件。

[root@localhost mysqllog]# ls log.sh mycommon-20140221.log mycommon-20140222.log mycommon-20140223.log mycommon-20140224.log mycommon-20140225.log mycommon.log myupdate.index [root@localhost mysqllog]# more myupdate.index /var/log/mysqllog/myupdate.000001 /var/log/mysqllog/myupdate.000002 /var/log/mysqllog/myupdate.000003 /var/log/mysqllog/myupdate.000004 /var/log/mysqllog/myupdate.000005 /var/log/mysqllog/myupdate.000006 /var/log/mysqllog/myupdate.000007 /var/log/mysqllog/myupdate.000008 /var/log/mysqllog/myupdate.000009 /var/log/mysqllog/myupdate.000010 /var/log/mysqllog/myupdate.000011 /var/log/mysqllog/myupdate.000012 /var/log/mysqllog/myupdate.000013 /var/log/mysqllog/myupdate.000014 /var/log/mysqllog/myupdate.000015 /var/log/mysqllog/myupdate.000016 /var/log/mysqllog/myupdate.000017 /var/log/mysqllog/myupdate.000018 /var/log/mysqllog/myupdate.000019 /var/log/mysqllog/myupdate.000020 /var/log/mysqllog/myupdate.000021 /var/log/mysqllog/myupdate.000022 /var/log/mysqllog/myupdate.000023 /var/log/mysqllog/myupdate.000024 /var/log/mysqllog/myupdate.000025 /var/log/mysqllog/myupdate.000026 /var/log/mysqllog/myupdate.000027 /var/log/mysqllog/myupdate.000028 /var/log/mysqllog/myupdate.000029 /var/log/mysqllog/myupdate.000030 /var/log/mysqllog/myupdate.000031 /var/log/mysqllog/myupdate.000032 /var/log/mysqllog/myupdate.000033 /var/log/mysqllog/myupdate.000034 /var/log/mysqllog/myupdate.000035 /var/log/mysqllog/myupdate.000036 /var/log/mysqllog/myupdate.000037 /var/log/mysqllog/myupdate.000038 /var/log/mysqllog/myupdate.000039 /var/log/mysqllog/myupdate.000040 /var/log/mysqllog/myupdate.000041 /var/log/mysqllog/myupdate.000042 /var/log/mysqllog/myupdate.000043 /var/log/mysqllog/myupdate.000044 /var/log/mysqllog/myupdate.000045 /var/log/mysqllog/myupdate.000046 /var/log/mysqllog/myupdate.000047 /var/log/mysqllog/myupdate.000048 /var/log/mysqllog/myupdate.000049 /var/log/mysqllog/myupdate.000050

原來這是記錄了所有文件的索引信息，是不是清空了就會(huì)重新創(chuàng)建000001文件呢，試了一下。

[root@localhost mysqllog]# >myupdate.index

?

[root@localhost ~]# /etc/init.d/mysqld restart 停止 mysqld： [確定] 正在啟動(dòng) mysqld： [確定]

果然可以正常啟動(dòng)了，再看目錄下面也確實(shí)創(chuàng)建了000001，不知道有沒有像我一樣遇到這樣問題的朋友，我覺得應(yīng)該會(huì)有什么命令可以重載myupdate.index文件，本人數(shù)據(jù)庫(kù)新手，雖然這個(gè)故障可能對(duì)于別人比較簡(jiǎn)單，記錄下來供剛?cè)腴T的朋友參考。
