初始化一套MySQL但拉起不來，日誌如下：
[Note] InnoDB: The InnoDB memory heap is disabled
[Note] InnoDB: Mutexes and rw_locks use GCC atomic builtins
[Note] InnoDB: Memory barrier is not used
[Note] InnoDB: Compressed tables use zlib 1.2.3

日誌實在是沒看出什麼問題。
檢查了初始化和啓動的命令後發現，啓動參數中指定的配置文件不存在。
指定正確的配置文件後，正常啓動。
mysqld_safe –defaults-file=/data/3316/conf/my.cnf –user=mysql&
