##安装composer
cd /usr/local/bin
curl -sS https://getcomposer.org/installer | php
执行发现失败了，提示如下：
Some settings on your machine may cause stability issues with Composer.
If you encounter issues, try to change the following:
The OpenSSL library (0.9.8zc) used by PHP does not support TLSv1.2 or TLSv1.1.
If possible you should upgrade OpenSSL to version 1.0.1 or above.
Downloading...
Could not create file /usr/local/bin/composer.phar: fopen(/usr/local/bin/composer.phar): failed to open stream: Permission denied
Download failed: fopen(/usr/local/bin/composer.phar): failed to open stream: Permission denied
fwrite() expects parameter 1 to be resource, boolean given
原来是Composer 依赖于 PHP，
