bin/mysqld_safe: Permission denied 这个问题如何解决啊？

我用bin/mysqld_safe --skip-name-resolve --user=mysql --socket=/home/mysql/mysql/mysql.sock &
启动报销：-bash: bin/mysqld_safe: Permission denied

网上查了下说是权限问题，我看了下mysql 目录的权限
drwxrwxr-x 14 root mysql 4096 2011-05-16 19:45 mysql

看了下文件夹下的权限
drwxrwxr-x 14 root mysql 4096 2011-05-16 19:45 .
drwxr-xr-x 7 root root 4096 2011-05-16 19:59 ..

这个问题到底如何解决啊，谢谢

chomod 777 .试试

用pwd看目前在哪个目录，要在mysql的安装目录下才能这样执行。

echo $USER;看看是哪个用户

我当前用户是root登录的，

我就是在mysql的安装目录下进行的

试了结果一样
