Automatic installation of Let’s Encrypt SSL certificate for nginx on Amazon Linux is not yet supported. Let’s see how we can do this manually.

To generate the certificate, execute:


ssh to@your.server.com
sudo service nginx stop
git clone https://github.com/letsencrypt/letsencrypt
git checkout amazonlinux
cd letsencrypt
sudo letsencrypt-auto -v

To fix painfully slow PHP mail function (you are also probably getting lots of

unable to qualify my own domain name

errors in /var/log/mail.log), make sure that both localhost and localhost.localdomain are in your /etc/hosts file:

127.0.0.1 localhost localhost.localdomain

As the last step, restart sendmail:

service sendmail restart

There is an annoying error when you try to pair the Visual Studio + Xamarin combo with Mac OS 10.10 Yosemite build host:

telnet [ip address of mac host] 5000

If you get an error similar to this:

system_profiler[18700:1303078] Error loading /System/Library/SystemProfiler/SPNVMeReporter.spreporter: Error Domain=NSCocoaErrorDomain Code=4 “The bundle “SPNVMeReporter.spreporter” couldn’t be loaded because its executable couldn’t be located.”

Go to /System/Library/SystemProfiler/ and most likely the SPNVMeReporter.spreporter bundle will have zero size. Delete it (or move it to a safe place) and try pairing again, it should work this time.
