无法初始化tc日志，中止| mysql事务日志导致启动失败。killall mysql进程后，mysql无法启动问题汇总；
问题1:
杀死杀死mysql进程后，重启，无法启动，报错：
110303 14:01:45 InnoDB: Started; log sequence number 0 138710263
/usr/local/MySQL/bin/mysqld:File .找不到/MySQL-bin。000041'(错误代码：13)
110303 14:01:45[ Error] Unable to open the log (file). /mysql-bin.000041' error number 13)
110303 14:01:45 [ERROR] Could not open log file
110303 14:01:45[ Error] Unable to initialize tc log.
110303 14:01:45 [ERROR] Aborting
在mysql/data/目录下找到mysql-bin.000041文件，删除，重启，还是不行，报错：
110303 14:04:07 InnoDB: Started; log sequence number 0 138710263
/usr/local/MySQL/bin/mysqld:File .找不到/MySQL-bin。000041'(错误代码：2)
110303 14:04:07[ Error] Unable to open the log (file). /mysql-bin.000041' error number 2)

110303 14:04:07[ Error] Unable to initialize tc log.
110303 14:04:07 [ERROR] Aborting
触摸，修改权限，重启，也不行，错误：
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] Unable to initialize tc log.
110303 14:05:41 [ERROR] Aborting
最终解决方案：
删除mysql/data/mysql-bin.index文件，重启mysql，会自动生成一个新的mysql-bin.index文件。启动成功。
问题2:
启动后，报告错误：
InnoDB: Started; log sequence number 0 1004308157
110303 14:15:01 [Note] Recovering after a crash using mysql-bin
110303 14:15:01[错误]Log _ event:read _ Log _ event()中的错误："读取错误"，数据长度：169，事件类型：2
110303 14:15:01[ Note] Crash recovery started …
110303 14:15:01 [Note] Crash recovery finished.
/opt/31306/mysql/bin/mysqld: The disk is full. /mysql-bin。 ~rec~' (error code: 28). Waiting for someone to free up space . (It is estimated that the server will be delayed to continue running for up to 60 seconds after releasing disk space)
这是因为mysql-bin日志太多了。进入mysql/data/目录后，所有mysql-bin。*文件果断删除，启动成功。
问题3:
启动后，报告错误：
110303 14:21:37 InnoDB: Started; log sequence number 0 487312871
110303 14:21:37[ Error] Unable to start the server on TCP/IP port: Bind: the address has been used.
110303 14:21:37 [ERROR] Do you already have another mysqld server running on port: 43306 ?
110303 14:21:37 [ERROR] Aborting
根据提示，43306端口应该被占用，但是检查后没有发现该端口被占用。没有深究，果断将my.cnf文件中的端口修改为新端口，并重启启动成功。收盘后，
把my.cnf中的端口改回43306，重启，又可以成功启动了。
