cant not run nginx with lua

[zhixiangjoy]

when I follow the step , I can't restart nginx :

# nginx -t
nginx: [emerg] unknown directive "lua_package_path" in /etc/nginx/conf.d/crowdsec_nginx.conf:1

There is some messages:

apt-get install lua5.3 libnginx-mod-http-lua lua-sec

Should I need install nginx-lua-module by mannul or install openresty? Thanks !

Hello,

Thanks for the report ! You shouldn't have to use openresty, nginx mod lua should do the trick.

The error nginx: [emerg] unknown directive "lua_package_path" in /etc/nginx/conf.d/crowdsec_nginx.conf:1 looks like lua was actually not installed as a nginx module (this directive is one of nginx).

Can you check if lua is correctly enabled at nginx level ?

Thanks,

[buixor]

@zhixiangjoy any update on this ?

[zhixiangjoy]

Thanks for your reply, It's my fault。I had modify the nginx.conf which had delete the line : include /etc/nginx/modules-enabled/*.conf; In that situation, nginx can't loading the lua lib.
