Yadda ake Shigar da Sanya Cryptmount a cikin Linux

A kan rarraba Debian/Ubuntu, zaku iya shigar da Cryptmount ta amfani da umarnin da ya dace kamar yadda aka nuna.

$ sudo apt install cryptmount

A kan rarraba RHEL/CentOS/Fedora, zaku iya shigar dashi daga tushe. Da farko fara shigar da fakitin da ake buƙata don yin nasarar ginawa da amfani da cryptmount.

# yum install device-mapper-devel   [On CentOS/RHEL 7]
