502 bad gateway nginx/WordPress

December 22, 2013 4.9k views
Hello! I've WordPress running on nginx, fastCGI. Currently I'm having issues on my droplet, when I try to load my domain I'm getting 502 bad gateway error. My site was infected with malware. Every PHP on server had a code with base64_decode() in it and I managed to remove it by using the method in [1]. After I removed the code using this method, I got a 502 bad gateway and when I tweaked my config using articles I found on various site, I ended up getting "Unable to connect" message on my browser. When I run the command `service nginx start` I get the following error. `nginx: configuration file /etc/nginx/nginx.conf test failed` And ` sudo service nginx status` gives me ` * could not access PID file for nginx` Any suggestions on getting around this?

After I removed the code using this method

Make sure you go over your code and try to find any vulnerabilities that could have caused that. Simply deleting the "bad" code is not enough.
nginx: configuration file /etc/nginx/nginx.conf test failed

There's an error in your configuration file. What's the output of
nginx -t
