Sentry is a popular error tracking solution. They have a free tier, but it is rather limited. Prices for the hosted tier currently start at $26/mo.
This repository lets you set up a self-hosted instance of Sentry
for only $5/mo. You need a (sub-)domain such as
Installation is mostly automatic and takes a little over 30 minutes
If you don't already have one, create a Linode account. Use the promo code DOCS10 for a $10 credit.
Create a Linode in Linode's Management interface. (If you haven't used them before: Linodes are simply private Linux servers.) For small projects, a Nanode for $5/mo is enough.
The Linode management interface should now show the IP of your
server. Update your domain's DNS settings so a new
A record points
to this IP. Typically, you'd use a subdomain such as
Open the management page for your new Linode. Click on Rebuild at the top. Select Debian 9 as the image and pick a password. Click Rebuild.
Installing Sentry requires about 4GB of RAM. If you chose a Nanode instance above, it only has 1GB. Go to the main management page for your Linode. You should see two disks:
First, click on Edit next to Debian 9 Disk. Reduce its size by 5GB. Once this process is complete, Increase the size of the Swap Image by 5GB.
Connect to your server via SSH. Clone this repository:
apt-get update apt-get install git -y git clone https://github.com/mherrmann/sentry-self-hosted.git
Use an editor such as
vi to change the settings at the top of
install.sh. Then, make the file executable and run it:
cd sentry-self-hosted chmod +x install.sh ./install.sh
The first time you do this, the script will ask you to log out and back in again. Do this but don't yet run the script again.
install.sh for a second time takes about 30 minutes.
We don't want this process to be interrupted in case your internet
connection drops. So it is highly recommended to install the
screen tool at this point. This keeps your terminal session alive
in case there are problems with your internet.
To install screen, log into the server and type the following:
apt-get install screen -y
This shows some information. Press ENTER. You are now in
a virtual terminal session hosted by
screen. Now execute
cd sentry-self-hosted ./install.sh
again. You can detach from this terminal session by pressing
Ctrl+A followed by D. To attach to
the session again (either because you detached from it or because
your connection dropped), type
screen -r on the command line.
The installation will prompt you to create a super user at some point. Provide it with some values.
Once the installation is complete, the server will automatically reboot. You can now log into it with the user credentials you created.
Once installation is complete, it's a good idea to decrease the swap size again (in case you increased it). Just follow the same steps as in 5.
Linode can automatically back up your server for an extra $2 per month. You can enable this in the management interface for your Linode.
