Yii framework Tutorial – How to Install ?
Prior to installing Yii, you must configure your application development environment as a web server capable of supporting PHP 5.1.0 or higher. Yii has been thoroughly tested with Apache HTTP server on Linux and Windows operating systems. It may also run on other web servers and platforms, provided PHP 5 is supported.
Let’s get started. First of all, download the application of Yii on the official website
http://www.yiiframework.com/download/, currently Yii 1.1 is the latest stable version. Extract the downloaded and store them in to local folder of our web server (in this case I’m using LAMP on linux so my server local folder located at
/var/www/). don’t forget to rename the folder name of our application into “yii” to facilitate our learning process.
After installing Yii, you may want to verify that your server satisfies Yii’s requirements. You can do so by accessing the requirement checker script via the following URL in a Web browser:
To create your first Yii application, open up your terminal, and navigate to a place in your filesystem where you will want to create your application’s folder structure. go a head into the yii folder by typing:
>> cd /var/www/yii/framework
after that, create new first app folder by typing this command
>> yiic webapp /var/www/learn-yii
if successfully, there will be showing the question that asking us to make new application in the root folder /var/www/learn-yii. please answer yes and type enter. make sure your php executable, already setting. for those of you who don’t succeed is because the path to PHP.exe not been directed, for windows setting, please click
start -> computer -> right click -> select properties -> select advanced system settings -> select environment variables -> select "PATH" and edit the last line then add in C:\xampp\php; (if you’re using XAMPP).
If your new application has been created successfully. next open up your browser and navigate to
http://localhost/learn-yii/. Here you will be presented with a My Web Application home page along with the friendly greeting Welcome to My Web Application, followed by some helpful information on the steps to be taken next. The next screenshot shows this example home page:
Perfect, your first yii application has been created successfully. In the next tutorial, i’ll guide you how to generate code using yicc shell.
