Can”t init tc log Aborting | mysql事務日誌導致啟動失敗問題，killall  mysql進程後，mysql無法啟動問題總匯；

問題1：

將mysql所（suǒ）有進程kill掉後，重啟，無法啟動，報錯：

110303 14:01:45 InnoDB: Started; log sequence number 0 138710263

/usr/local/mysql/bin/mysqld: File ‘./mysql-bin.000041′ not found (Errcode: 13)

110303 14:01:45 [ERROR] Failed to open log (file ‘./mysql-bin.000041′, errno 13)

110303 14:01:45 [ERROR] Could not open log file

110303 14:01:45 [ERROR] Can’t init tc log

110303 14:01:45 [ERROR] Aborting

在（zài）mysql/data/目錄下找到mysql-bin.000041文件，刪掉，重（chóng）啟，仍不行，報錯（cuò）：

110303 14:04:07 InnoDB: Started; log sequence number 0 138710263

/usr/local/mysql/bin/mysqld: File ‘./mysql-bin.000041′ not found (Errcode: 2)

110303 14:04:07 [ERROR] Failed to open log (file ‘./mysql-bin.000041′, errno 2)

110303 14:04:07 [ERROR] Could not open log file

110303 14:04:07 [ERROR] Can’t init tc log

110303 14:04:07 [ERROR] Aborting

touch之，修改權限，重啟，也不行（háng），報錯：

110303 14:05:41 InnoDB: Started; log sequence number 0 138710263

110303 14:05:41 [ERROR] I/O error reading the header from the binary log, errno=-1, io cache code=0

110303 14:05:41 [ERROR] I/O error reading the header from the binary log

110303 14:05:41 [ERROR] Can’t init tc log

110303 14:05:41 [ERROR] Aborting

最後解決辦法：

將mysql/data/mysql-bin.index文件刪除，重啟mysql，會自動生成新的mysql-bin.index文件，啟動成功

問（wèn）題2：

啟動後，報錯：

InnoDB: Started; log sequence number 0 1004308157

110303 14:15:01 [Note] Recovering after a crash using mysql-bin

110303 14:15:01 [ERROR] Error in Log_event::read_log_event(): ‘read error’, data_len: 169, event_type: 2

110303 14:15:01 [Note] Starting crash recovery…

110303 14:15:01 [Note] Crash recovery finished.

/opt/31306/mysql/bin/mysqld: Disk is full writing ‘./mysql-bin.~rec~’ (Errcode: 28). Waiting for someone to free space… (Expect up to 60 secs delay for server to continue after freeing disk space)

這是由於mysql-bin日誌過（guò）多，進入mysql/data/目錄，果斷（duàn）刪除所有mysql-bin.*文件，重啟，啟動成功

問（wèn）題3：

啟動後，報錯：

110303 14:21:37 InnoDB: Started; log sequence number 0 487312871

110303 14:21:37 [ERROR] Can’t start server: Bind on TCP/IP port: Address already in use

110303 14:21:37 [ERROR] Do you already have another mysqld server running on port: 43306 ?

110303 14:21:37 [ERROR] Aborting

按（àn）提示（shì），應該是43306端口占用，但是查看後並未發現（xiàn）該端口被占用，不深究（jiū），果斷將其my.cnf文（wén）件中的port修改成一個（gè）新的端（duān）口，重啟，啟動成功。關閉後，重新將my.cnf中的（de）port改回（huí）為43306，重啟，又可以成（chéng）功啟動了。
