How to view nginx log on Centos (docker)? I get 502, 504 Nginx Gateway errors, so I want to see nginx log. Can you tell me command line, how to view nginx log on Centos (docker)?

Discourse runs inside a Docker container, which is essentially like a virtual machine. All components are self-contained so it is rather difficult to lose anything. To see the logs that the NGINX server produces, such as access and error, you’ll need to go to the logs folder inside the container’s shell. Exercise caution while inside the shell, as this can break your instance. Enter your container’s shell using these commands. You can skip su - if you’re already root. su - cd /var/discourse ./launcher enter app cd /var/log/nginx Open the file error.log in your preferred terminal text editor (I prefer nano only because I’m not an expert, you’ll need to install it first). nano error.log Locate the last line (the latest entry) of the file by pressing ^V (CTRL-V). When finished, press ^X to return to shell. When finished, run exit to return to your CentOS root shell.

I got this error when I followed your instructions -bash: cd: /var/log/nginx: No such file or directory

Go to the /var/log directory and reply with the results of the ls command.

I did as you instructed, returned the following results, What do I do next to see the nginx log? [root@45 discourse]# cd /var/log/ [root@45 log]# ls anaconda cron-20211101 maillog-20211017 ppp spooler-20211024 audit cron-20211107 maillog-20211024 rhsm spooler-20211101 boot.log dmesg maillog-20211101 secure spooler-20211107 btmp dmesg.old maillog-20211107 secure-20211017 tallylog btmp-20211101 firewalld messages secure-20211024 tuned chrony grubby messages-20211017 secure-20211101 wtmp cron grubby_prune_debug messages-20211024 secure-20211107 yum.log cron-20211017 lastlog messages-20211101 spooler yum.log-20200101 cron-20211024 maillog messages-20211107 spooler-20211017 yum.log-20210114

I have seen Nginx, but do you know: what command to get into nginx log? [image]

@pfaffman i did like you, but i still get the error: [root@45 var-log]# cd /var/discourse/shared/standalone/logs/var-log/nginx -bash: cd: /var/discourse/shared/standalone/logs/var-log/nginx: No such file or directory [root@45 var-log]# /var/discourse/shared/standalone/logs/var-log/nginx -bash: /var/discourse/shared/standalone/logs/var-log/nginx: No such file or directory

What if you do an ls in the var-log directory that you are in?

[תמונה] pfaffman: See /var/discourse/shared/standalone/logs/var-log/nginx Try it again, but replace the folder logs with log, like below. I also got the error on my machine. /var/discourse/shared/standalone/log/var-log/nginx

This is an old topic, but running nginx -V inside the container should indicate where nginx’s log files are.
