install question

[AnoopAlias]

I have installed openresty under /etc/nginx
and installed lua-resty-waf using command

/etc/nginx/bin/opm install p0pr0ck5/lua-resty-waf

I have also copied the rules folder from git to

ls /etc/nginx/site/lualib/rules/
11000_whitelist.json       21000_http_anomaly.json  40000_generic_attack.json  42000_xss.json     99000_scoring.json
20000_http_violation.json  35000_user_agent.json    41000_sqli.json            90000_custom.json

I am testing the settings using the example config from the docs and nginx -t shows fine . But the site itself is not loading

nginx error log says

# tail -f /var/log/nginx/error_log

What am I doing wrong?

Thanks in advance

Hi @AnoopAlias,

Thanks for checking us out! Apologies for the delayed in response, I've been on holiday. Currently, installation via OPM isn't currently working, as OPM doesn't support executing steps for building projects as part of installation: openresty/opm#30.

Until then, it's best to install via Luarocks, or manually via the Makefile (make && make install). I will update the docs to discourage the use of OPM for the time being. Thanks!
