few causes of (and solutions to) this Varnish 503 error. Before we start One of the most confusing (but nonetheless very cool) things about Varnish is that it does not store any logs on disk. All log entries go directly into memory. This allows varnish cache server 503 guru meditation for better performance and efficient disk usage. So to view the logs, you'll have to fire
Varnish Cache Server Error 503 Service Unavailable
the following command: varnishlog Once the command is running, load up a page from your website on your browser and look for any errors. error 503 service unavailable service unavailable guru meditation wordpress This literally means looking for the word "error". Pretty sweet, huh! Now let's get on to our first solution. Solution 1 - General check Most of the times, Varnish 503 means Varnish cannot connect with your backend (Apache,
Guru Meditation Website Error
Nginx, etc…). So you should start from there. The first thing is to make sure your backend is correctly configured. That means making sure your Apache/Nginx/whatever is running properly before installing Varnish. If you've installed Varnish on a properly running instance, then you might just check that installing Varnish hasn't done anything funny to your Apache configurations. Here's what you can do: Open your Varnish configuration file. Mine was in /etc/varnish/user.vcl backend default { .host = "127.0.0.1"; .port = "8888"; .connect_timeout = 1s; how to fix guru meditation error } We can see that Varnish is trying to connect to port 8888 on the same machine. But is our backend responding correctly there? Let's try this (make sure you run this on your server, this port will probably be blocked to the outside world): wget http://www.your-site.com:8888 This will create an HTML file with the output in your current directory. Open the file and see if it matches your website's homepage. If it does not, then you need to configure your server. This is beyond the scope of this post, I'll advise you to check the Linode Library for resources. Solution 2 - Increase timeouts A frequent cause of Varnish 503 errors is timeouts between Varnish and your backend. This is quite easy to solve. Open your Varnish configuration file (mine was in /etc/varnish/user.vcl) and add these lines: backend default { .host = "127.0.0.1"; .port = "8888"; .connect_timeout = 1s; # Wait a maximum of 1s for backend connection (Apache, Nginx, etc...) .first_byte_timeout = 5s; # Wait a maximum of 5s for the first byte to come from your backend .between_bytes_timeout = 2s; # Wait a maximum of 2s between each bytes sent } The settings are pretty straightforward. The most important settings here is the first_byte_timeout. So go ahead and play with those settings until you find the sweet spot for your server. Solution 3 - Turn KeepAlive
