Nginx Conf.d went missing

Well need alot of troubleshooting here and questions and answers.

Troubleshooting

1. What was previous Nginx version you were on ?
2. Are you running as full root user when you do upgrades or running as a sudo user you created ?

As full root user in SSH, what's output for this command below - wrap output in CODE tags

Code (Text):

history | egrep -w 'conf.d|rm' | grep '.11.17'

and output for

Code (Text):

ls -lah /usr/local/nginx/conf/conf.d/

For posting code you might want to use CODE tags for code How to use forum BBCODE code tags

To troubleshoot, you need to check the the nginx upgrade log at /root/centminlogs and instructions under Sharing logs and errors heading for using Pastebin.com or Gists to share a sanitised version of the contents of the nginx_upgrade.log log. You can see full details at How to troubleshoot Centmin Mod initial install issues

also what's output of

Code (Text):

nginx -t

when you run centmin.sh menu option 4 there's a nginx upgrade log timestamped at /root/centminlogs

if you type this command it lists all logs in date ascending order so latest log at bottom

Code (Text):

ls -lArt /root/centminlogs

so copy the entire contents of latest nginx_upgrade log to gist.github.com or pastebin.com

you can use grep to filter the logs, i.e. look for nginx_upgrade in log name

Code (Text):

ls -lahrt /root/centminlogs/ | grep nginx_upgrade
-rw-r--r--  1 root root 3.2M Oct 11 15:55 centminmod_1.2.3-eva2000.09.001_111016-155345_nginx_upgrade.log
-rw-r--r--  1 root root 672K Oct 11 22:06 centminmod_1.2.3-eva2000.09.001_111016-220515_nginx_upgrade.log

So the last nginx upgrade log was named centminmod_1.2.3-eva2000.09.001_111016-220515_nginx_upgrade.log and located at /root/centminlogs/centminmod_1.2.3-eva2000.09.001_111016-220515_nginx_upgrade.log

then use cat command to output the contents of that log

clear your ssh window buffer/screen and type

Code (Text):

cat /root/centminlogs/centminmod_1.2.3-eva2000.09.001_111016-220515_nginx_upgrade.log

then select and copy and paste output to pastebin.com or gist.github.com file to share. If your SSH client's scroll buffer isn't large enough using cat might not output the entire log file contents, so you may need to download the log and use local text editor to open and copy and paste.

so only need content of one specific log, in this case most recent nginx_upgrade.log log

Restoring Nginx Auto Backups

Each time you upgrade Nginx an auto backup of nginx conf files and ssl directories is generated. See http://centminmod.com/nginx.html#autobackup and http://centminmod.com/configfiles.html

So if you accidentally deleted your Nginx vhost files at /usr/local/nginx/conf/conf.d/ and/or SSL files at /usr/local/nginx/conf/ssl/ you can restore a previous copy from /usr/local/nginxbackup which has 2 directories

1. /usr/local/nginxbackup/confbackup which is backup for everything within /usr/local/nginx/conf including subdirectories like /usr/local/nginx/conf/conf.d/
2. /usr/local/nginxbackup/nginxdirbackup which is backup for everything within /usr/local/nginx/ including subdirectories

Code (Text):

ls -lah /usr/local/nginxbackup
total 32K
drwxr-xr-x.   4 root root 4.0K Apr  4  2017 .
drwxr-xr-x.  22 root root 4.0K Sep  9 05:27 ..
drwxr-xr-x. 212 root root  12K Nov 20 00:25 confbackup
drwxr-xr-x. 212 root root  12K Nov 20 00:25 nginxdirbackup

So for instance for backup dated 310817 = 31 August, 2017 at /usr/local/nginxbackup/confbackup/conf_310817-005457/conf.d/ would have Nginx vhost config files which were backed up from /usr/local/nginx/conf/conf.d/

Code (Text):

ls -lah /usr/local/nginxbackup/confbackup/conf_310817-005457/conf.d/

-rw-r--r--  1 root root 1.1K Aug 30 18:55 demodomain.com.conf
-rw-r--r--  1 root root 2.0K Aug 30 18:55 domain1.com.conf
-rw-r--r--  1 root root 3.3K Aug 30 18:55 domain1.com.ssl.conf
-rw-r--r--  1 root root  846 Aug 30 18:55 ssl.conf
-rw-r--r--  1 root root 2.6K Aug 30 18:55 virtual.conf

and /usr/local/nginxbackup/confbackup/conf_310817-005457/ssl would contain the nginx ssl certificate files backed up from /usr/local/nginx/conf/ssl

So contents of /usr/local/nginxbackup/confbackup/conf_310817-005457/ssl

Code (Text):

ls -lah /usr/local/nginxbackup/confbackup/conf_310817-005457/ssl

drwxr-xr-x. 2 root root 4.0K Apr  4  2017 domain1.com

has /usr/local/nginxbackup/confbackup/conf_310817-005457/ssl/domain1.com backups for /usr/local/nginx/conf/ssl/domain1.com

Code (Text):

ls -lah /usr/local/nginxbackup/confbackup/conf_310817-005457/ssl/domain1.com
total 40K
drwxr-xr-x. 2 root root 4.0K Apr  4  2017 .
drwxr-xr-x. 6 root root 4.0K Jun 23 11:24 ..
-rw-r--r--. 1 root root  424 Apr  4  2017 dhparam.pem
-rw-r--r--. 1 root root  952 Apr  4  2017 domain1.com-backup.csr
-rw-r--r--. 1 root root 1.7K Apr  4  2017 domain1.com-backup.key
-rw-r--r--. 1 root root 1.1K Apr  4  2017 domain1.com.crt
-rw-r--r--. 1 root root  952 Apr  4  2017 domain1.com.csr
-rw-r--r--. 1 root root 1.7K Apr  4  2017 domain1.com.key
-rw-r--r--. 1 root root   45 Apr  4  2017 hpkp-info-primary-pin.txt
-rw-r--r--. 1 root root   45 Apr  4  2017 hpkp-info-secondary-pin.txt

 

there's the problem you ran this command on Nov 20th at 10:11 pm

Code (Text):

 1501  [20.11.17] 22:11:53   rm -rf cd /usr/local/nginx/conf/conf.d/

which means rm -rf = delete both directory cd and directory /usr/local/nginx/conf/conf.d/

so find a backup within /usr/local/nginxbackup/confbackup/ which is most recent

list directories in ascending date order so most recent directory is listed last from command

Code (Text):

ls -lahrt /usr/local/nginxbackup/confbackup/

and restore it's contents to /usr/local/nginx/conf/conf.d/

i.e. if most recent is at /usr/local/nginxbackup/confbackup/conf_100117-135040/conf.d, then change into directory, copy all files to nginx vhost directory and then list contents of that directory and restart nginx

Code (Text):

cd /usr/local/nginxbackup/confbackup/conf_100117-135040/conf.d
\cp -af * /usr/local/nginx/conf/conf.d/
ls -lah /usr/local/nginx/conf/conf.d/
ngxrestart

 

Yeah it's why i created that auto nginx conf directory backup routine which runs everytime you run centmin.sh menu option 4 to recompile/upgrade/downgrade nginx versions
