在 Ubuntu 14.04 安裝 Laravel 4.2

使用 composer 指令安裝 laravel 4.2

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

composer create-project [PACKAGE] [DESTINATION PATH] [--FLAGS] 

若出現以下訊息表示你沒有安裝 Mcrypt PHP extension

Mcrypt PHP extension required.
Script php artisan clear-compiled handling the post-install-cmd event returith an error

檢查有無安裝 Mcrypt

$ php --ri mcrypt

有安裝 Mcrypt 會出現

Extension 'mcrypt' not present.

沒有安裝 Mcrypt 會出現

mcrypt support => enabled 

安裝 Mcrypt PHP extension

$ sudo apt-get install php5-mcrypt 

啟動Mcrypt，並在重新檢測有無安裝成功

$ sudo php5enmod mcrypt

若原先安裝laravel時安裝失敗後，還要重新安裝至相同目錄，必須要將該安裝失敗的目錄清空，安裝laravel時必須安裝在一個空的資料夾

安裝完後將網站跟目錄指定為 laravel/public 下即可

變更Laravel 4資料夾群組及寫入權限問題

$ sudo chgrp -R www-data /home/kejyun/laravel
$ sudo chmod -R 775 /home/kejyun/laravel/app/storage

Let's play Laravel 4！！
