升级、备份红帽PaaS openshift 上的 wordpress

红帽提供了一个很稳定的PAAS服务平台：openshift！此博客即作为wordpress建在里面。 这里记录怎样升级与备份wordpress。

预备： 安装 openshift command line tool rhc:

$gem install rhc

$rhc setup

$rhc apps                        得到应用名称=>$APPS

升级wordpress：

$mkdir ~/website

$rhc git-clone $APPS

下载wordpress安装包，比如wordpress-3.9.zip。

$unzip wordpress-3.9.zip

$cd ~/website/$APPS/

$mv $APPS/  bk

$cp wordpress $APPS/

$cp bk/wp-config.php $APPS/

$rm -rfv bk

$git add .

$git commit -m "update to new wordpress3.9."

成功后显演示样例如以下信息：
