How to correctly update the nginx version?

Question

Nginx

The server is running version 1.6.3. nginx, I thought about updating, please tell me which version can be updated without any conflicts and how should this process work properly?

Answer 1

Yes, just connect the official nginx repository
and install the latest version from there.
Of the conflicts, it may be that if you used spdy before, then in nginx 1.9.5+ it was replaced with http2. Accordingly, in the configs, you need to replace the line
with
listen 443 ssl http2;
