先提醒下：升级有危险，为了安全请备份重要数据！！！！
言归正传，升级步骤如下：
wget -q -O – http://www.atomicorp.com/installers/atomic.sh | sh
yum upgrade
service httpd restart
这里可能会丢失一些原本php安装的扩展，需要重新一一安装，比如我这里原来安装的php memcache扩展就不能用了，重新安装步骤如下：
wget http://pecl.php.net/get/memcache-3.0.5.tgz
tar -xvzf memcache-3.0.5.tgz
cd memcache-3.0.5
phpize
./configure
make && make install
service httpd restart
可以用弄个phpinfo();的php页面检查下有没有加载php memcache扩展
