Useful nginx files that I will probably need and which I will forget if I cannot read them from here.

---

FUTURE WARNING

These files may age badly, so here are some hopefully timeless pointers:

• Generate the config file with https://ssl-config.mozilla.org/ (and if time eats it, try https://github.com/mozilla/ssl-config-generator/ in hope of finding where it is now. * Name it 00-something so it will be the first file read and make everything a different file.
• If using my acmesh-ssl.bash script, the files to fill should be like:

(the script runs $ACMESH --key-file $NGINXDIR/key.pem --fullchain-file $NGINXDIR/cert.pem --reloadcmd "$SYSTEMCTLRESTART nginx")

• ssl_certificate, ssl_trusted_certificate are cert.pem
• ssl_certificate_key is key.pem

The header syntax is following, THIS LIKELY WON’T TIME WELL, ESPECIALLY CSP

    add_header Strict-Transport-Security "max-age=63072000; includeSubDomains" always;
    add_header X-Frame-Options "SAMEORIGIN" always;
    add_header Content-Security-Policy "block-all-mixed-content; default-src 'none'; form-action 'self'; connect-src 'self' ws: wss:; style-src 'self' https: 'unsafe-inline'; script-src 'self'; worker-src 'self'; child-src 'self'; manifest-src 'self'; font-src 'self' https:; media-src 'self' https:; img-src 'self' data: https://user-images.githubusercontent.com" always;
    add_header X-Content-Type-Options "nosniff" always;
    add_header Referrer-Policy "no-referrer" always;

The CSP comes from HEAD "http://[::]:9000/#/chan-1" to figure out what TheLounge would be setting without a reverse proxy in front of it. HEAD is in Debian package libwww-perl

• Refer to tester tools to see if the configuration is fine:

Arch

Remove the default server block and add to http block:

include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;

PHP: todo. It has something to do with php-fpm.sock instead of php5-fpm.sock, but that doesn’t appear to be enough.
