Issue After restarting the sever in plesk, plesk stopped working

kevin722 · Jul 17, 2017

Hello there,

My website stopped working for some reason so I rebooted the server. The website didn't work and plesk worked fine. I went and restarted the server from plesk, then plesk stopped working too. I rebooted the server from my hosting provider panel and nothing.

I tried to use putty and nothing. It's like the server IP is not working anymore.

Any help please?

Be sure fail2ban doesn't ban you (check access from other public IP-address).

Do you use Plesk in a cloud environment? In Amazon, as an example, if you do not use Elastic IP, server's public IP changed every time after an instance shutdown/launch (Installing Plesk on Amazon Web Services).

I can reboot the server just fine. The reboot doesn't fix anything though.

I tried with a different IP and still nothing.

No. I have a dedicated server.

Please help. My website and Plesk are still down.

Do you have access to Linux via SSH? Can you open the Linux server console? If you can't, you should open a ticket to hosting provider because we can't help here.

If you can ssh to the server, check `dmesg`, log-files, running services. Need more information for investigating.

How do I check dmesg?

AYamshanov · Jul 18, 2017

So, you have access to the server? Which OS do you use?

As an example, CentOS7 with systemd:
- if dmesg command returns nothing, skip this step.

- check enabled services (from test server):
# systemctl list-unit-files | grep ^sw-
sw-collectd.service enabled
sw-cp-server.service enabled
sw-engine.service enabled

- check running services:
# ps ax | grep sw-
2808 ? Ss 0:00 sw-cp-server: master process /usr/sbin/sw-cp-serverd -c /etc/sw-cp-server/config
4648 ? S 0:00 sw-engine-kv
11309 ? Ssl 0:11 /usr/sbin/sw-collectd -f
23353 ? S 0:01 sw-cp-server: worker process
23382 ? Ss 0:00 sw-engine-fpm: master process (/etc/sw-engine/sw-engine-fpm.conf)
26538 pts/0 S+ 0:00 grep --color=auto sw-

- check opened ports:
# netstat -anpo4 | grep sw-
tcp 0 0 0.0.0.0:8880 0.0.0.0:* LISTEN 2808/sw-cp-server: off (0.00/0/0)
tcp 0 0 0.0.0.0:8443 0.0.0.0:* LISTEN 2808/sw-cp-server: off (0.00/0/0)

- check connecting from localhost:
# telnet localhost 8880
Trying ::1...
Connected to localhost.
Escape character is '^]'.
GET /

<html><head>
<meta charset="utf-8">
[...]

- check log files in /var/log/plesk:
/var/log/plesk/httpsd_access_log
/var/log/plesk/panel.log

- check log files in /var/log/plesk/sw-cp-server

- check logs: more /var/log/messages

Please check first: Is nginx, apache, mysql and php-fpm services are running?

What says system log file?

You are startet plesk repair all?

So plesk is now working; however, the only website I am running on it is NOT working.

Is there any service stopped? (no green light leading)

It looks like you have configured cloudflare service:

Does your DNS working and translated correct IP?

What kind of CF service do you configured? CNAME based DNS? or cloudflare managed DNS?
Do you have try to turn off CF to troubleshoot the website directly?

I am pretty sure the problem is not caused by cloudflare. The problem appeared after restarting the server.

No

No? That can not be.

Please check which service is started. Please post the output of:

Code:

service --status-all
