laravel Install

本文主要介绍了安装Laravel框架的几种方法,以及Laravel框架的服务器环境要求及相关配置,非常实用,有需要的朋友可以参考下

安装Composer

Laravel框架使用Composer(PHP包管理工具,参考 Composer 中文文档)来管理代码依赖性。 首先,你需要下载Composer的PHAR打包文件( composer.phar ),下载完成后把它放在项目目录下或者放到 usr/local/bin 目录下以便在系统中全局调用。在Windows操作系统中,,你可以使用Composer的Windows安装工具。

安装Laravel

通过 Laravel 安装器安装

先下载 Laravel 安装器 PHAR 文件。为了方便起见,将该文件重命名为 laravel 并移动至 /usr/local/bin 目录。完成后,只需在你指定的目录下输入简单的 laravel new 命令即可创建一个全新的Laravel安装。例如,laravel new blog 将创建一个名为 blog 的目录,该目录中包含了一份全新的Laravel安装以及所需的依赖项。这种安装方法比通过 Composer 安装要快许多。

通过 Composer create-project 命令安装Laravel

还可以通过在命令行执行 Composer create-project 命令来安装Laravel:

复制代码 代码如下:


composer create-project laravel/laravel --prefer-dist

通过下载Laravel包安装

Composer安装完成后,下载最新版Laravel框架,把它解压缩到你服务器上的一个目录中。然后在Laravel应用的根目录下运行命令行命令 php composer.phar install (或者 composer install )来安装所有的框架依赖包。在此过程中,为了成功完成安装,你需要在服务器上安装好Git。

当Laravel框架安装好后,你可以使用命令行命令 php composer.phar update 来更新框架。

服务器环境要求

Laravel框架有一些系统要求:

PHP最低版本: 5.3.7
MCrypt PHP扩展
从PHP 5.5版本开始,针对某些操作系统的安装包需要你自己手工安装PHP的JSON扩展模块。如果你使用的是Ubuntu,可以通过, apt-get install php5-json 命令直接安装。(译者注:还是Ubuntu傻瓜化啊!!!)

配置

Laravel框架几乎无需配置就可立即使用。你可以自由地快速开始开发。然而,你也许希望先查看下 app/config/app.php 配置文件和相关的文档说明。它包含了一些你也许要修改的配置选项,如 时区 和 地区 等。

复制代码 代码如下:


Once Laravel is installed, you should also configure your local environment. This will allow you to receive detailed error messages when developing on your local machine. By default, detailed error reporting is disabled in your production configuration file.

Note: You should never have app.debug set to true for a production application. Never, ever do it.

权限设置

Laravel框架有一个目录需要额外设置权限: 需要为 app/storage 目录下的文件设置写权限。

路径设置

一些框架目录路径是可以设置的。如果需要改变这些目录的位置,可以查看 bootstrap/paths.php 文件中的设置。

优雅链接

Apache 服务器

Laravel框架通过设置 public/.htaccess 文件去除链接中的index.php。 如果你你的服务器使用的是Apache,请开启mod_rewrite 模块。

如果框架附带的 .htaccess 文件在你的Apache环境中不起作用,请尝试下面这个版本:

复制代码 代码如下:


Options +FollowSymLinks
RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)/$ %{HTTP_HOST}/$1 [R=301,L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]

Nginx 服务器

如果是 Nginx 服务器,将下列指令放到网址的配置文件中,就能让网址更优雅了:

复制代码 代码如下:


location / {
    try_files $uri $uri/ /index.php?$query_string;
}
