Hello, this is not a panel install of nginx. It is recommended that you check the startup log

aaP_constantinos23

Hello, thanks for the reply.

The logs add /www/wwwlogs/nginx_error.log are empty. Also tried to reinstall nginx, but now nginx is installed at the default location of ubuntu.

When i do /etc/init.d/nginx start, just freeze there without an error.

Another issue i have is that App Store doesn't load, so i dont have access to the services of aapanel.

aaPanel_Kern

Hello, is the problem solved? Is it normal to try restarting the panel? Also check if the server can connect to our node server?
restart panel: bt restart

curl -v https://brandnew.aapanel.com
ping brandnew.aapanel.com -c 5
ping google.com -c 5
curl -v http://brandnew.aapanel.com

No still facing the issues.

All ping commands and curl works, so communication is ok.
Also i tried restart and fix many times, same problem with nginx

aaPanel_Kern

Hello, is it possible to solve the problem by trying to install apache?
First close all nginx and then install apache
killall nginx

A few time ago I wrote a shell script to fix nginx with aaPanel.
You can find it there.

Hello, I cannot see the specific problem. What is your operating system and version?
Execute this command to see if there are any errors:
/www/server/nginx/sbin/nginx -t

I had the same issue Failed to start LSB: starts the nginx web server..

After checking, there were no logs available apart from this. Also error logs at /www/wwwlogs/nginx_error.log was empty.

After changing error_log /www/wwwlogs/nginx_error.log crit; to error_log /www/wwwlogs/nginx_error.log debug; in /www/server/nginx/conf/nginx.conf and starting nginx again, I was able to observe the following error:

root@hostname:/www/server/nginx# cat /www/wwwlogs/nginx_error.log 
2024/11/28 02:17:08 [error] 29252#0: init_by_lua_file error: /www/server/free_waf/init.lua:7: module 'cjson' not found:
        no field package.preload['cjson']
        no file '/www/server/free_waf/cjson.lua'
        no file './cjson.so'
        no file '/usr/local/lib/lua/5.1/cjson.so'

stack traceback:
        [C]: in function 'require'
        /www/server/free_waf/init.lua:7: in main chunk

Then I remembered I had installed the Nginx Free WAF Official App. After uninstalling it, NGINX can now be restarted successfully.

Two suggestions for the aapanel team:

Please lower the error log level so errors like this can be surfaced to the user
Please fix Nginx Free WAF.

Thank you!!

aaPanel_Kern

Hello, thank you for your feedback. To use Nginx Free WAF, please use nginx 1.22 and below.

Hi, I was using Nginx 1.25 I believe. I am now using Nginx 1.27 and just confirmed installing Nginx Free Firewall still breaks Nginx. I will keep it uninstalled for now. Thank you!

# Install Nginx Free Firewall breaks it
root@hostname:/www/server/nginx# systemctl stop nginx && systemctl start nginx
Job for nginx.service failed because the control process exited with error code.
See "systemctl status nginx.service" and "journalctl -xeu nginx.service" for details.

# Uninstall Nginx Free Firewall and run again:
root@hostname:/www/server/nginx# systemctl stop nginx && systemctl start nginx
root@hostname:/www/server/nginx# # Working again.
