How to modify the default installation directory of Snap in Centos7? In order to solve this problem, today the editor summarizes this article to modify the default installation directory of Snap, hoping to help more friends who want to solve this problem to find a more simple and easy way.
Description
Recently received the company server alarm message, mount=/var/lib/snapd/snap/core/8592 100 > = 90. This is because the installation of Snap takes up disk space (the default installation directory is / var/lib/snapd). If you want Snap to be installed in a specific directory, you cannot use the method of creating soft links (ln-s) to associate to the new installation directory, otherwise the application of Snap will not start normally.
Here are the main ways to change the default installation directory ~
Main steps
(1) check the mount of snap
Df-h | grep snapd/dev/loop2 92m 92m 0100% / var/lib/snapd/snap/core/8592/dev/loop0 92m 92m 0100% / var/lib/snapd/snap/core/8689
(2) check the running status of snapd service
Systemctl status snapd
(3) stop snapd service
Systemctl stop snapd
(4) Uninstall snapd's / dev/loopxx device
Umount / dev/loop2umount / dev/loop0
(5) create a new data directory for snap
Mkdir / root/snap/snapd
(6) copy data
Rsync-avzP / var/lib/snapd/ / root/snap/snapd/
(7) backup of other data
Cp / etc/fstab / etc/fstab.bakmv / var/lib/snapd / var/lib/snapd.bak
(8) write snap mount information into / etc/fstab file
Echo "/ root/snap/snapd / var/lib/snapd none bind 0" | tee-a / etc/fstab
(9) remount the snap in fstab or restart the machine
Mkdir / var/lib/snapdmount-a
(10) check whether the snapd service has been mounted and started successfully
Ls / var/lib/snapd/ | if grep snaps# exists, the mount is successful. Otherwise, fail ~ systemctl start snapdsnap list
