mysql無法啟動的解決辦法
MySQL無法啟動
在停止mysql之後，執行了一些操作（如修改主機名），重新啟動 mysql，發現起不來。
[root@www ~]$ service mysql start Starting MySQL..^[[A.................................................................................................. ERROR! The server quit without updating PID file (/disk/mysql/www.pid). [root@www ~]$ service mysql stop ERROR! MySQL server PID file could not be found! [root@www ~]$ service mysql stop ERROR! MySQL server PID file could not be found! [root@www ~]$ service mysql start Starting MySQL.................. 還是老樣子，只好 Ctr+C 掉。 [root@www ~]$
實在是啟動不了，看一下日誌：/disk/mysql/www.err

好像是原來的 mysqld 並沒有停下來。
強制終止 mysqld
