安装virtualmin出现错误： /tmp directory is mounted noexec. Installation cannot continue. 怎么办？
通常这是你的IDC给你的服务器做了安全设置导致的。给/tmp加了noexec保护。要临时取消他，建议用命令：mount -o remount,exec /tmp /var/tmp
Sounds like /tmp is mounted with "noexec", which is preventing the installation from continuing ;-)
Setting the tmp partition to use the "noexec" option is not a default for any distro I'm familiar with, so that was likely added in manually. You'll need to remove that option in order for Virtualmin to install.
To disable it, you'll need to do two things:
1.Edit /etc/fstab, and remove the noexec option from the line that sets up /tmp. That'll make sure the mount options are correct next time you reboot.
2.To change the current options /tmp is mounted with, you can type: mount -o remount,exec /tmp
You'll want to do both of those steps -- one fixes things now, the other makes sure they stay fixed later :-)
