MySQL Server 无法启动错误诊断一则

mysql select version()\G; *************************** 1. row *************************** version(): 5.5.16-log 1 row in set (0.00 sec) [mysql@cdio ~]$ mysqld_safe [1] 3036 [mysql@cdio ~]$ 130506 19:16:34 mysqld_safe Logging to /home/mysql/

mysql> select version()\G;
*************************** 1. row ***************************
version(): 5.5.16-log
1 row in set (0.00 sec)

[mysql@cdio ~]$ mysqld_safe &
[1] 3036
[mysql@cdio ~]$ 130506 19:16:34 mysqld_safe Logging to '/home/mysql/mysql/log/alert.log'.
130506 19:16:34 mysqld_safe Starting mysqld daemon with databases from /home/mysql/mysql/data
130506 19:16:36 mysqld_safe mysqld from pid file /home/mysql/mysql/data/cdio.pid ended

查看日志、发现：
130506 17:40:19 [ERROR] /home/mysql/mysql/bin/mysqld: unknown variable 'inactive_timeout=172800'
130506 17:40:19 [ERROR] Aborting

原来是inactive_timeout拼错了、该参数为interactive_timeout

细心啊细心啊、、、、
