# Remove any old runtimes from this directory.
cd /Library/Developer/CoreSimulator/Profiles/Runtimes
# e.g.
sudo rm -rf iOS\ 8.1.simruntime

1. Open a command prompt and navigate to /etc/nginx/ssl

2. Issue "openssl req -new -newkey rsa:2048 -nodes -keyout server.key -out server.csr" 

3. Get your certificate issued - Go to your certificate authority and give them the CSR (server.csr)

4. Copy your new crt (that the certificate authority issued) to the /etc/nginx/ssl and give it read priveledges

5. Reconfigure your nginx.conf, here is mine.  The first part redirects 80 to 443, the second part listens to 443 and is optimized to return Ruby on Rails application requests using gzip and unicorn.

# 1) Create your private key (any password will do, we remove it below)

$ cd ~/.ssh
$ openssl genrsa -des3 -out server.orig.key 2048


# 2) Remove the password

$ openssl rsa -in server.orig.key -out server.key

//Swift1.2之后的最佳单例模型
/*这种写法不仅简洁，而且保证了单例的独一无二。在初始化类变量的时候，Apple 将会把这个初始化包装在一次 swift_once_block_invoke 中，以保证它的唯一性。另外，我们在这个类型中加入了一个私有的初始化方法，来覆盖默认的公开初始化方法，这让项目中的其他地方不能够通过 init 来生成自己的 MyManager 实例，也保证了类型单例的唯一性。
