Question

I never had problems and now I can not access any of my sites, it shows me error 502

Hi,

I am emailing in regards to my server. Since 3 days ago it has been down and I can see a 504 Gateway Time-out, I have checked all the connections and their are all working but still getting the 504 error. This is the same as this link https://www.digitalocean.com/community/questions/how-to-solve-this-error-connect-to-unix-var-run-php5-fpm-sock-failed

I have follow all the instructions to solve this problem, even modifying the config fie /etc/php/5.6/fpm/pool.d/

user = www-data group = www-data listen = /var/run/php5-fpm.sock listen.owner = www-data listen.group = www-data listen.mode = 0660

pm = dynamic ; pm.max_children = (total RAM - RAM used by other process) / (average amount of RAM used by a PHP process) pm.max_children = 15 ; pm.start_servers = min_spare_servers + (max_spare_servers - min_spare_servers) / 2 pm.start_servers = 5 pm.min_spare_servers = 5 pm.max_spare_servers = 10

chdir = /

but still getting the same error.

Also, in my /var/log/nginx/error.log I can see the log as follow:

2017/07/19 10:39:40 [error] 572#0: *9379 connect() to unix:/var/run/php5-fpm.sock failed (11: Resource temporarily unavailable) while connecting to upstream, client: 185.188.204.25, server: upram.com.ar, request: “POST /xmlrpc.php HTTP/1.0”, upstream: “fastcgi://unix:/var/run/php5-fpm.sock:”, host: “46.101.214.187”

At this point I don’t know what else to try. I would really appreciate if you can confirm that my server is up and running correctly and/or give me an idea about what it could be.

Hi @cacivio

If you run the command top, I’m guessing you’re seeing several php-fpm running at 100% (or very high) CPU load? It could be that PHP just locked up and you need to restart it:

sudo service php5-fpm restart

I want to block two ip 185.188.204.25 185.188.204.27

Apologize I went back to attack before I finished doing my backup are two ip I want to block them in the firewall but I do not find where log 185.188.204.27 - - [19/Jul/2017:20:09:35 -0400] “POST /xmlrpc.php HTTP/1.0” 499 0 “-” “Mozilla/4.0 (compatible: MSIE 7.0; Windows NT 6.0)” 185.188.204.27 - - [19/Jul/2017:20:09:36 -0400] “POST /xmlrpc.php HTTP/1.0” 499 0 “-” “Mozilla/4.0 (compatible: MSIE 7.0; Windows NT 6.0)” 185.188.204.25 - - [19/Jul/2017:20:09:36 -0400] “POST /xmlrpc.php HTTP/1.0” 499 0 “-” “Mozilla/4.0 (compatible: MSIE 7.0; Windows NT 6.0)” 185.188.204.27 - - [19/Jul/2017:20:09:37 -0400] “POST /xmlrpc.php HTTP/1.0” 499 0 “-” “Mozilla/4.0 (compatible: MSIE 7.0; Windows NT 6.0)” 185.188.204.25 - - [19/Jul/2017:20:09:37 -0400] “POST /xmlrpc.php HTTP/1.0” 499 0 “-” “Mozilla/4.0 (compatible: MSIE 7.0; Windows NT 6.0)” 185.188.204.25 - - [19/Jul/2017:20:09:38 -0400] “POST /xmlrpc.php HTTP/1.0” 499 0 “-” “Mozilla/4.0 (compatible: MSIE 7.0; Windows NT 6.0)” 185.188.204.27 - - [19/Jul/2017:20:09:38 -0400] “POST /xmlrpc.php HTTP/1.0” 499 0 “-” “Mozilla/4.0 (compatible: MSIE 7.0; Windows NT 6.0)” 185.188.204.27 - - [19/Jul/2017:20:09:39 -0400] “POST /xmlrpc.php HTTP/1.0” 499 0 “-” “Mozilla/4.0 (compatible: MSIE 7.0; Windows NT 6.0)” 185.188.204.25 - - [19/Jul/2017:20:09:39 -0400] “POST /xmlrpc.php HTTP/1.0” 499 0 “-” “Mozilla/4.0 (compatible: MSIE 7.0; Windows NT 6.0)” 185.188.204.27 - - [19/Jul/2017:20:09:40 -0400] “POST /xmlrpc.php HTTP/1.0” 499 0 “-” “Mozilla/4.0 (compatible: MSIE 7.0; Windows NT 6.0)” 185.188.204.25 - - [19/Jul/2017:20:09:40 -0400] “POST /xmlrpc.php HTTP/1.0” 499 0 “-” “Mozilla/4.0 (compatible: MSIE 7.0; Windows NT 6.0)”

Update everything and it seems that everything is stable. Thank you very much for your comments. root@debian-2gb-fra1-01:~# uname -a Linux debian-2gb-fra1-01 4.11.0-2-amd64 #1 SMP Debian 4.11.11-1 (2017-07-17) x86_64 GNU/Linux root@debian-2gb-fra1-01:~# nginx -v nginx version: nginx/1.13.3

I did that, and it lasted 5 minutes, I had never had that problem before, and I did not change anything in my configuration, I could write a script that executes that statement every 5 minutes but it does not seem to be a viable solution
