• How to install mod_rpaf Varnish WordPress Ubuntu

    And the geekiest title of the week goes to me…

    Add this line to your varnish VCL in sub_recv:

    set req.http.X-Forwarded-For = client.ip;

    Grab mod_rpaf:

    wget http://ftp.debian.org/debian/pool/main/liba/libapache2-mod-rpaf/libapache2-mod-rpaf_0.6-7_amd64.deb

    Install mod_rpaf

    dpkg -i libapache2-mod-rpaf_0.6-1_amd64.deb

    Enable mod_rpaf:

    a2enmod rpaf

    Your rpaf config (/etc/apache2/mods-enabled/rpaf.conf) should look awesome like this:

    <IfModule mod_rpaf.c>
RPAFenable On
RPAFsethostname On
RPAFproxy_ips 123.123.123.123 10.0.0.2 127.0.0.1
RPAFheader HTTP_X_FORWARDED_FOR
</IfModule>

    Note: RPAFproxy_ips is the ips of your varnish cache servers. Varnish is awesome.

    Reload varnish and Apache the cool way.

    /etc/init.d/varnish reload
/etc/init.d/apache reload

    Test it by looking at your remote_addr variable:

    print_r($_SERVER);
