Site down, can't start Nginx Reverse Proxy, FTP Server & Varnish Cache Server

Hi,

Distro Name: CentOS Linux release 7.7.1908 (Core)
Kernel Version: 2.6.32-042stab127.2

I'm having issues accessing my site,
I logged into CWP and see Nginx Reverse Proxy, FTP Server & Varnish Cache Server are down.

Just noticed some of the mail services failed to start too after server reboot.

Dovecot IMAP/POP3 Server      
ClamAV      
AMaViS (A Mail Virus Scanner)
SpamAssassin

Not sure how to fix all issues.

Here's some status info for Nginx Reverse Proxy..

I posted this the other night, I was attempting to update the kernel, don't think it worked.

You can try to check the nginx config with the command: nginx -t and then fix all found errors.

Thanks Igor,

I went to the SSL Certificates section and restarted the web server, then nginx was online.

I got this when I ran nginx -t

$ nginx -t
nginx: [warn] the "ssl" directive is deprecated, use the "listen ... ssl" directive instead in /etc/nginx/conf.d/vhosts/clients.dreamstream.it.ssl.conf:8
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

I am unable to restart the ftp server and Vanish Cache Server.

Also some of the mail services are down.

I'll start another thread for those.

I guess you can't access your websites in this case.
remove all ssl certificates if you don't have too many websites...
restart server
will probably work on nginx
then add ssl certificates again
check each added ssl certificate website and then add another

or check which website has a problem with the error codes. simply delete their ssl certificates and reinstall them.

I am able to access the website again, after I did the reload web server in ssl section,

I just did a google about:

nginx: [warn] the ssl directive is deprecated, use the listen ... ssl directive instead

I went to /etc/nginx/conf.d/vhosts/clients.dreamstream.it.ssl.conf:8
And deleted the line for: ssl                  on;
And added: listen 443 ssl;

Then did nginx -t and got:

user@ $ nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

I guess that fixed it?

I guess you had issue with the hostname SSL. Probably you could fix it with the command:

Code: [Select]

sh /scripts/generate_hostname_ssl
