Link SSL certificates

Door | 19 January 2019

SSL in DirectAdmin (versions may differ in setup)

Source of certificate:

Create symlinks with:
ln -sf /path/to/filetolinkto /path/to/linktocreate

Webserver Apache level:
SSLEngine on
SSLCertificateFile /etc/httpd/conf/ssl.crt/server.crt
SSLCertificateKeyFile /etc/httpd/conf/ssl.key/server.key
SSLCACertificateFile /etc/httpd/conf/ssl.crt/

Controlpanel DirectAdmin level:

Webserver Nginx level:
when proxy: /etc/httpd/conf/ssl.crt/server.crt.combined
in case being used: /etc/nginx/ssl.crt/server.crt.combined

Mail Transfer Agent Exim level:
/etc/exim.key (private key)
/etc/exim.cert (certificate followed by bundle)

IMAP / POP3 server Dovecot:
in /etc/dovecot/conf/ssl.conf and /etc/dovecot/conf/sni/

in my setup leading to:

/etc/proftpd.conf easily links to the exim certificate files.
Note: I needed in /etc/ssh/ for restart of ProFTPd: chmod 600 ssh_host_rsa_key

/etc/pure-ftpd.pem cannot easily link to one file containing private key followed by certificate and bundle.
