How do you update SSL certifcate? There are instructions for installing new one

March 18, 2017 3.4k views

Hi there,
I already put my SSL certificate on a year ago. I have the .crt file for the new one but the instructions on the site are only for adding a new one. How do you just update the files?

I have two files ready to add:
Your PositiveSSL Certificate - wwwmysiteconz.crt
Your Apache “bundle” file - www

I’ve put the wwwmysiteco_nz.crt file on my server in the same folder as the csr files. What next?

My 000- default.conf now looks like this.

<VirtualHost *:80>
Redirect permanent /
<VirtualHost *:443>
# The ServerName directive sets the request scheme, hostname and port that
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request’s Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.

SSLCertificateFile /var/www/mysite/wwwmysiteco_nz.crt
SSLCertificateKeyFile /var/www/mysite/

SSLCACertificateFile /var/www/mysite/intermediate.crt

DocumentRoot /var/www/mysite/public

# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,

# It is also possible to configure the loglevel for particular

#LogLevel info ssl:warn

ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined

# For most configuration files from conf-available/, which are
# enabled or disabled at a global level, it is possible to
# include a line for only one particular virtual host. For example the
# following line enables the CGI configuration for this host only
# after it has been globally disabled with "a2disconf".
#Include conf-available/serve-cgi-bin.conf

If you used the same key, you just replace the .crt file and restart your webserver.

  • Hi there,
    I don’t know what you mean by ‘if you used the same key’? I have a new .crt file. I’ve uploaded that into the root folder. I deleted the old keys. I restarted. Now there are no key files in there. Do I need to recreate the .key and .csr files somehow?
