How to update Ghost 6

It will be essential to have the ownership and permissions of the Ghost directory correctly configured. Therefore, first switch to the Ghost user:

# su ghostinst

Next, access the Ghost path:

# cd /var/www/ghost

Then run a Ghost diagnostic check: 

# ghost doctor

All checks should appear as correct, as shown in the following result:

Ghost Backup

Before updating Ghost, it is recommended to have a backup of it. Therefore, you can directly use the native built-in tool. Running the following will create a Ghost backup:

# ghost backup

You can also use a snapshot of the server instead of using Ghost's native option; it will be faster and safer than storing the backup on the same server.

Updating to the latest version of Ghost

Once the previous preparation steps are completed, run an update to update Ghost.

# ghost check-update
