directory and restart this script from there as follows:

[1]+  Exit 1                  mysqld_safe --skip-grant-tables --user=mysql
 

說明：mysqld_safe啟動指令碼預設的從/usr/local/mysql目錄中讀取另外一個啟動指令碼mysqld，因為我的安裝目錄為/home/mysql/product/5.6/mysql-1。所以找不到相關檔案。可以從兩個方面解決。

方法一：在/usr/local/mysql建立連結檔案

mkdir -p /usr/local/mysql/bin
ln -s /home/mysql/product/5.6/mysql-1/bin/mysqld /usr/local/mysql/bin/mysqld

方法二：將mysqld_safe中的所有/usr/local/mysql目錄改為自己實際的安裝目錄

<pre name="code" class="sql">sed -i 's#/usr/local/mysql#/home/mysql/product/5.6/mysql-1#g' /home/mysql/product/5.6/mysql-1/bin/mysqld_safe
 

再次啟動成功。
