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 guru meditation website error directly into memory. This allows for better performance and efficient disk usage. So to view

the logs, you'll have to fire the following command: varnishlog Once the command is running, load up a page from your guru meditation xid varnish cache server website on your browser and look for any errors. 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, 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 how to fix guru meditation error configuration file. Mine was in /etc/varnish/user.vcl backend default { .host = "127.0.0.1"; .port = "8888"; .connect_timeout = 1s; } 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 setti

Instead, I'd suggest that you start on a local or development box not behind memcache and varnish, set up the site as you see fit, and migrate the code and database over (or simply turn on varnish/memcache at that time if you have access).

In this case it is 'Service Unavailable' The service http://stackoverflow.com/questions/27739853/varnish-cache-server-error-503-service-unavailable you are trying to use is set up to use a 'frontend' caching server.The thing you have asked to see is not available in the cache, so varnish has to go and talk to the real server which is temporarily unavailable.It is similar to going to a store and guru meditation asking to buy an item.If they have it on the shelf they will sell it to you there and then otherwise they will have to go into the back room and find one.While they are in the back room they do the smart thing and bring back extra items to place on the shelf. This means that anyone that comes along varnish cache server after you and asks for the same thing can buy it without the wait.The Error comes when the door to the back room is locked.62.4k Views · View UpvotesRelated QuestionsMore Answers BelowWhat is Error 503 Backend fetch failed?What does the error window "error 0x80070091 mean?What is 503 error?What does a 302 error code mean?Why is Codechef showing 503 Internal Error?
