我在solaris上安装mysql总是报这样的错：

## 执行预安装正文
/opt/mysql/mysql/bin/mysqld: Can 't read dir of '/var/tmp//installq0a4xc/ ' (Errcode: 13)
/opt/mysql/mysql/bin/mysqld: Can 't read dir of '/var/tmp//installq0a4xc/ ' (Errcode: 13)
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/opt/mysql/mysql/bin/mysqladmin -u root password 'new-password '
/opt/mysql/mysql/bin/mysqladmin -u root -h Jephirus password 'new-password '
See the manual for more instructions.

我已经搞了好几天了都没解决，望高手们帮我看看是何原因，谢谢！！！


[解决办法]
第一：检查下载文件正确性
第二：查看权限，最好设置一个mysql用户组和mysql用户名
估计第二方面的可能性比较大。
[解决办法]
13 EACCES Permission denied.
不是root用户？
