Yii learning summary installation configuration, yii summary installation configuration

I have written articles about Yii before, and I just have nothing to do during the holidays, so I will combine the previous articles, the official documentation of Yii, and the recent harvest about Yii to summarize and write a series~~

Yii is a high-performance component-based PHP framework for developing large-scale web applications. Yii is written in strict OOP and has complete library references and comprehensive tutorials. From MVC, DAO/ActiveRecord, widgets, caching, hierarchical RBAC, web services, to theming, I18N and L10N, Yii provides almost everything needed for today's Web 2.0 application development. In fact, Yii is one of the most efficient PHP frameworks. Yii is a high-performance PHP5 web application development framework. A simple command line tool yiic can quickly create a web application code framework. Developers can add business logic based on the generated code framework to quickly complete application development.

Install Yii

Before installing Yii, you must configure your development environment, such as a web server that supports PHP5.1.0 or above. Yii has been tested on the Apache web server on Windows and Linux operating systems. It may also run on web servers that support PHP5 on other platforms. There are many free resources published on the Internet, and you may get a web server environment configured with PHP5. Here we will leave aside the web server and PHP5 installation.
The installation of Yii is actually very simple. It only requires two steps:
Download the Yii framework from http://www.yiiframework.com/ Unzip the downloaded file to a directory accessible to the web server.
After the installation is complete, it is recommended that you check whether the current server meets all Yii requirements.
Fortunately, doing this is easy, and Yii comes with a simple inspection tool. To call it, enter: http://yourhostname/path/to/yii/requirements/index.php in your browser address bar. Your server's configuration will be displayed below. Use the check tool to determine that the server does not have extensions or components installed and used, but it only gives a suggestion to ensure that the installation can be determined. As you can see, not all of the following check results are in Passed status, but some also show Warning. Of course, your configuration may be slightly different, and therefore, your display results will be different. In fact, it is not necessary to pass all the details below. But part of it is also necessary. According to the content of the Conclusion paragraph: your server configuration meets the minimum requirements of Yii. (Your server configuration satisfies the minimum requirements by Yii.)

Create a new application
The installation location of Yii is something you already know
WebRoot is the root directory of your web server configuration
From your command line, go to the framework directory and execute the following:

Copy code The code is as follows:

% cd Webroot/testdrive/framework
% yiic webapp ../../testdrive
Create a Web application under '/WebRoot/testdrive'? [Yes|No]
Yes
           mkdir /WebRoot/testdrive
           mkdir /WebRoot/testdrive/assets
           mkdir /WebRoot/testdrive/css
           generate css/bg.gif
           generate css/form.css
           generate css/main.css

Your application has been successfully created under /WebRoot/demo. The purpose of this webapp command is to create a brand new Yii application. It only requires specifying a parameter, whether it is an absolute or relative path and the application will be created. The directories and files it generates are just a skeleton of the application.

Copy code The code is as follows:

testdrive/
index.php Web application entry script file
index-test.php Entry script file used for functional testing
assets/ Contains public resource files
css/ Contains CSS files
images/ Contains image files
themes/ Contains application themes
protected/ Contains protected application files

shell/ Contains custom 'yiic shell' commands components/ contains reusable user components
              Controller.php               The base class for all controller classes
Identity.php The 'Identity' class used for authentication
                                                                                                                                                                                                                            Console.php Console application configuration
                                                                                                                                                                                                               test.php Configuration used for functional testing

Schema.mysql.sql example mysql database
            schema.sqlite.sql   Example SQLite database
          testdrive.db         Sample SQLite database file
Extensions/ Contains third-party extensions

Models/ Class files containing models
LoginForm.php Form model for 'login' action
ContactForm.php 'contact' action form model

tests/ tests/ Contains test scripts
views/ Contains the controller’s view and layout files
Layouts/Including layout view files
Main.php The default layout of all views of all views
Column1.php The layout used by a single -column page
                                                                                                                                                  ’ ’ s ’ s ’ s ’ s ’ s ’ s 1 t                     ’ ‐ down to column ’s ’ s ’ t it t ‐ to column2.php       Site/View file containing the 'Site' controller
pages/ Contains "static" pages
View of the "about" page about.php
               contact.php      View of the 'contact' action
             error.php        View of the 'error' action (shows external errors)
View of 'index' action
View of 'login' action
system/ Contains system view files

Without writing a line of code at this time, we can access the following URL in the browser to see our first Yii application:

http://hostname/testdrive/index.php

As we will see, this application contains three pages: home page, contact page, and login page. The homepage displays some information about the application and the user's login status, the contact page displays a contact form for users to fill out and submit their inquiries, and the login page allows users to first authenticate and then access authorized content.

Configuration

In this application, no matter which page URL you go to, index.php is included. What should I do if I want to remove it?

1. Enable apache's mod_rewrite module, remove the "#" symbol in front of LoadModule rewrite_module modules/mod_rewrite.so, and make sure there is "AllowOverride All" in .

2. Add code to /protected/config/main.php in the project:

Copy code The code is as follows:

'components'=>array(
...
            'urlManager'=>array(
                 'urlFormat'=>'path',
'Showscriptname' = & gt; false, // Note that False does not use quotes
                'rules'=>array(
'sites'=>'site/index',
),
),
...
),

3. Configure the server, Yii can be configured under Apache and Nginx

1) Apache

Under the Apache server, Yii needs to configure the .htaccess file. The configuration is as follows

Copy code The code is as follows:

RewriteEngine on
# prevent httpd from serving dotfiles (.htaccess, .svn, .git, etc.)
RedirectMatch 403 /..*$
# if a directory or a file exists, use it directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# otherwise forward it to index.php
RewriteRule .index.php

2) Nginx

Yii can use Nginx and PHP’s FPM SAPI. The configuration is as follows

Copy code The code is as follows:

server {
    set $host_path "/www/mysite";
    access_log  /www/mysite/log/access.log  main;
    server_name  mysite;
    root   $host_path/htdocs;
    set $yii_bootstrap "index.php";
    charset utf-8;
    location / {
        index  index.html $yii_bootstrap;
        try_files $uri $uri/ /$yii_bootstrap?$args;
    }
    location ~ ^/(protected|framework|themes/w+/views) {
        deny  all;
    }
    #avoid processing of calls to unexisting static files by yii
    location ~ .(js|css|png|jpg|gif|swf|ico|pdf|mov|fla|zip|rar)$ {
        try_files $uri =404;
    }
    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ .php {
        fastcgi_split_path_info  ^(.+.php)(.*)$;
        #let yii catch the calls to unexising PHP files
        set $fsn /$yii_bootstrap;
        if (-f $document_root$fastcgi_script_name){
            set $fsn $fastcgi_script_name;
        }
        fastcgi_pass   127.0.0.1:9000;
        include fastcgi_params;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fsn;
        #PATH_INFO and PATH_TRANSLATED can be omitted, but RFC 3875 specifies them for CGI
        fastcgi_param  PATH_INFO        $fastcgi_path_info;
        fastcgi_param  PATH_TRANSLATED  $document_root$fsn;
    }
    # prevent nginx from serving dotfiles (.htaccess, .svn, .git, etc.)
    location ~ /. {
        deny all;
        access_log off;
        log_not_found off;
    }
}

 使用如上配置，你可以在php.ini中设置cgi.fix_pathinfo=0，这样可以避免许多不必要的系统的stat()调用。
