For official upgrade document, follow this link. This post still has a purpose, because the official documentation does not talk about what to do if you have customized certain aspects of your blog. For example, if you click this link Services, you will be taken to our services page in the same window. However, if you click on any external link like Digital Ocean it will open the link in a new tab!
If you are new to Ghost platform, you can read our other posts on Ghost here.
NOTE: DO NOT REPEAT THE FOLLOWING STEPS IN PRODUCTION DIRECTLY. FAMILIARIZE YOURSELF WITH THE CONCEPT AND START WITH YOUR STAGING OR DEVELOPMENT ENVIRONMENT
Step 1: Download Ghost
Start by downloading the latest version of Ghost on your server.
curl -LOk https://ghost.org/zip/ghost-latest.zip
Step 2: Unzip Archive
The downloaded file is a ZIP file and you need to unzip it using the following command.
unzip ghost-latest.zip -d ghost-temp
Step 3: Install
Navigate to the directory and install Ghost by using the following commands...
cd ghost-temp npm install --production
Step 4: Check Installation
To confirm that the installation is successful, run
firstname.lastname@example.org start /home/ec2-user/ghost-temp > node index WARNING: Ghost is attempting to use a direct method to send email. It is recommended that you explicitly configure an email service. Help and documentation can be found at http://support.ghost.org/mail. Migrations: Creating tables... Migrations: Creating table: posts Migrations: Creating table: users Migrations: Creating table: roles Migrations: Creating table: roles_users Migrations: Creating table: permissions Migrations: Creating table: permissions_users Migrations: Creating table: permissions_roles Migrations: Creating table: permissions_apps Migrations: Creating table: settings Migrations: Creating table: tags Migrations: Creating table: posts_tags Migrations: Creating table: apps Migrations: Creating table: app_settings Migrations: Creating table: app_fields Migrations: Creating table: clients Migrations: Creating table: client_trusted_domains Migrations: Creating table: accesstokens Migrations: Creating table: refreshtokens Migrations: Creating table: subscribers Migrations: Running fixture populations Migrations: Creating owner ERROR: (EADDRINUSE) Cannot start Ghost. Port 2368 is already in use by another program. Is another Ghost instance already running?
Notice the last line. Even though it is erroring out due to Port 2368, I would assume that if I stop my current Ghost site, the current command will work. However, I would not do that because the data is not migrated yet. Sometimes a package or two fails during
npm install and it is a good time fix that before proceeding ahead.
Step 5: Take Backup
Ensure that you take a backup before proceeding ahead and navigate to the directory.
cp -R website website-backup cd website
NOTE: THE FOLLOWING COMMANDS REQUIRES DOWNTIME SO CHOOSE A SUITABLE TIME
#Remove the core directory rm -rf core #Copy the core files from fresh installation cd ../ghost-temp/ cp -R core ~/website cp index.js *.json ~/website #Change to your website and install dependencies cd ~/website npm install --production
Step 6: Re-Apply your code changes
Now, reapply your code changes. If you maintain the website using Git, it is a piece of cake. You just need to document and remember the files where you have made changes. Let's say you have made changes to a specific file and you want to reapply those changes. You can view the difference and reapply your code changes appropriately. If you think your code is "additive" in nature and no other part has been modified in the latest build of Ghost, you can simply type the following command to revert the changes using:
git checkout core/server/routes/frontend.js
NOTE: THE FILES WILL BE DIFFERENT IN YOUR CASE. SUIT YOURSELF!
Step 7: Restart and Clean Up
If you use PM2 to manage your Node application,
PM2 restart app-name will restart the application and you should be good to go.
To clean up, just delete the following and move your backup directory to an appropriate folder:
rm ghost-latest.zip rm -rf ghost-temp/ mv website-backup backups/yyyy-mm-dd/
And you are done! Welcome to the shiny new version of Ghost :)
