hello,

I try  installing brotli as per instructions here: https://wiki.centos-webpanel.com/enabling-brotli-compression-on-nginx

however

Apr 30 19:28:57 hostname nginx[11905]: nginx: [emerg] dlopen() "/etc/nginx/modules/ngx_http_brotli_filter_module.so" failed (libbrotlienc.so.1: cannot open shared object file: No such file or directory) in /etc/nginx/nginx.conf:7



[root@s01 modules]# head /etc/nginx/nginx.conf

[root@s01 modules]# nginx -v
nginx version: nginx/1.20.2

any idea?

I did it with this tutorial, the only thing I did was to adapt it to Centos 7.
