Nginx My nginx is down

hi, my nginx is down

when i "systemctl status nginx.service" i get
Starting SYSV: Nginx is an HTTP(S) server, HTTP(S) reverse proxy and IMAP/POP3 proxy server...
Starting nginx: nginx: [emerg] unknown directive "more_set_headers" in /usr/local/nginx/conf/nginx.conf:41
[FAILED]
ginx.service: control process exited, code=exited status=1


how can i fix this?

Hi Eva, thank you for your answer.
here:
LETSENCRYPT_DETECT='y'
NGXDYNAMIC_NGXPAGESPEED='y'
NGINX_PAGESPEED='y'
MARCH_TARGETNATIVE='n'


as far as i noticed, my linode went out of space. and that must caused something..
it is quite weird actually.
i updated centmin menu #4 (nginx)
and my websites are back

BUT my xf website is not working.

"Chris D" says "Your MySQL server is refusing the connection that XF is trying to make. "

when i try to visit my xf website i get http500 error,
when i try to upgrade my xf from 2.0.1 to 2.0.2 it gives
"XF\Db\Exception: No such file or directory in src/XF/Db/Mysqli/Adapter.php at line 160"

how can i check whats wrong?

 

i deleted a 16gb file, it should be ok now
Filesystem Type Size Used Avail Use% Mounted on

/dev/root ext4 47G 26G 19G 59% /

/dev/loop0 ext4 5.8G 25M 5.5G 1% /tmp

tmpfs tmpfs 394M 0 394M 0% /run/user/0


what can i do now?
a wordpress site is working fine, a html website working just fine but my xf website is down.

 

actually, the wordpress website giving errors too
"Error establishing a database connection"

it was looking OK because it has a caching plugin on..

 

so, there is something wrong with the mysql.. how can i check whats wrong?

 

service mysql restart

Restarting mysql (via systemctl): Job for mariadb.service failed because the control process exited with error code. See "systemctl status mariadb.service" and "journalctl -xe" for details.

i solved.
I ended up deleting the tc.log file in /var/lib/mysql. When I started mysql again, it created a new tc.log and started up.

 

what can be my next step? how can i check?

 

Eva, so sorry to bother you... it went down again...
i checked and saw this:
Starting nginx: nginx: [emerg] duplicate location "/src/" in /usr/local/nginx/conf/conf.d/iamtravelr.com.ssl.conf:92

and i commented the lines as:
#location /src/ {
# internal;
# allow 127.0.0.1;
# deny all;
#}

restarted the nginx and sites back.. did i do this correctly?

what i can see is only i need to uncomment cloudflare as i am not using it. I cant see anything else wrong, anyone else?

 

Eva thank you, so as far as i understand, my action was enough, right? ( autoprotect file stays untouched)
or whats the difference between i comment the lines on autoprotect conf file and normal confd file above?
