client: 127.0.0.1, server: ,
request: "GET / HTTP/1.1",
upstream: "fastcgi://unix:/var/run/hhvm/sock:",

actually /var/run/hhvm/ contains only hhvm.hhbc.. getting 502 BAD GATEWAY

I reinstalled HHVM. then missing files are reinstalled. all the dependent files are correctly restored.

After auto upgrade to 5.8 seeing errors and site unusable

After an auto upgrade to 5.8 seeing this error... can't even run the wp-cli to downgrade back to 5.7.2. I forgot to turn off the auto upgrade to this one particular site...

The critical error is caused by the Gutenberg plugin attempting to redeclare the class WP_Block_Template which is now included as part of the WordPress Core as of version 5.8

To resolve this issue, uninstall the Gutenberg plugin.
For WP-CLI, use the command:
wp plugin uninstall gutenberg

Trouble using Meteor-Please to deploy to Centos/RHEL

I've been trying for sometime to use the mplz utility to deploy and run a Meteor app. It seems (well now it seemed) simpler and more unified than Meteor Up which said it was targeted towards Debian/Ubuntu distros.
After running a successful mplz setup on a clean CentOS7 image, I cannot access the app. All I have ever gotten is an "nginx error!" page. In the nginx error log I saw this at first:
2016/03/14 17:14:47 [crit] 4997#0: *2 connect() to 127.0.0.1:3000 failed (13: Permission denied) while connecting to upstream, client: myLocalIP, server: domain.com, request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:3000/", host: "domain.com"
After doing some research I believe I fixed the permissions issue by changing the nginx user and adding the users to the appropriate groups. The website still only displayed the nginx error page, but had a new message in the error_log.
I am now getting a connection refused error:
2016/03/14 18:15:59 [error] 2489#0: *2 connect() failed (111: Connection refused) while connecting to upstream, client: myLocalIp, server: domain.com, request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:3000/", host: "domain.com"
All I'm really trying to get done is deploy a persistent copy of my Meteor app to the server. I am not at all familiar with nginx or server-ops kind of stuff, I've mainly worked on existing websites working on features.
I would love any suggestions of how to solve this issue OR how to better or more easily deploy Meteor to a public server.

HHVM 502 gateway error on high load

I have a codebase that's running fine con HHVM.
I'm realizing some load tests with apache ab tool but when i test with 100 concurrent requests I start to get 502 gateway errors.
I generally only get two types of logs in nginx's error log:
2015/01/10 09:42:48 [crit] 29794#0: *302 connect() to
unix:/var/run/hhvm/hhvm.sock failed (2: No such file or directory)
while connecting to upstream, client: 192.168.56.211, server: ,
request: "GET /api/v2/checkaccess HTTP/1.1", upstream:
"fastcgi://unix:/var/run/hhvm/hhvm.sock:", host: "instela.com"
2015/01/10 09:42:26 [error] 29794#0: *264 connect() to
unix:/var/run/hhvm/hhvm.sock failed (111: Connection refused) while
connecting to upstream, client: 192.168.56.211, server: , request:
"GET /api/v2/checkaccess HTTP/1.1", upstream:
"fastcgi://unix:/var/run/hhvm/hhvm.sock:", host: "instela.com"
Under high load this error occurs on all load balanced backends servers, so it's not a server specific problem (I hope)
Mostly after some time HHVM returns back but many times I had to restart the daemon to bring the server back.
I am using the default configuration mostly. Here I've my configuration: http://pastie.org/9823561

I have a mediawiki installation and an IPB installation. They both through up errors but this one error from mediawiki prevents me from posting semi-large articles. I have tried a lot of the solutions out there, adding catch_workers_output = yes, adjusting pm.* settings. Still not able to resolve this issue. I am coming to my wits end trying to figure this one out.

If the failure depends on size of the pages, it has to do with how much work the operation causes. My wild guess would be: increase the timeout (you currently have send_timeout 60s;).
It's easy for the parse time of a very long page to go over 60 seconds, especially if you're on a low power server, have not tuned performance or have enabled heavy parser extensions.
in my case it was that the php version of the project was different with the version of php I had been

502 Bad Gateway error with nginx and unicorn

I have nginx 1.4.1 and unicorn set up on centos - I am getting a 502 Bad Gateway error and my nginx logs shows this:
1 connect() to unix:/tmp/unicorn.pantry.sock failed (2: No such file or directory)
while connecting to upstream, client: 192.168.1.192, server: , request: "GET / HTTP/1.1",
upstream: "http://unix:/tmp/unicorn.pantry.sock:/", host: "192.168.1.30"
There is no /tmp/unicorn.pantry.sock file or directory. I am thinking that it might be a permission error and therefore the file can't be written if so who requires what permission - I have also read that I can create a tcp client
Also I don't understand where the 192.168.1.192 comes from
I just want to make it work How can I do it?
Ok I figured this out. I had unicorn.sock in my shared directory so I needed to point unix: to it
