Ubuntu下Laravel安装教程-优快云博客

本文链接：https://blog.youkuaiyun.com/yoywow/article/details/52074512

环境:ubuntu14.04
官方文档:
http://www.golaravel.com/laravel/docs/4.2/installation/

1.第一步安装 Composer
终端命令(推荐)
4步曲

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('SHA384', 'composer-setup.php') === 'e115a8dc7871f15d853148a7fbac7da27d6c0030b848d9b3dc09e2a0388afed865e6a3d6b3c0fad45c48e2b5fc1196ae') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"

先下载一个composer-setup.php文件,然后校验,然后安装,最后把composer-setup.php文件删掉

我选择手动安装,就是下载一个文件 ,Composer 的 PHAR 打包文件（ composer.phar ）
https://getcomposer.org/download/
选择最近版本吧

Latest Snapshot
1.2.0 (2016-07-18)
1.2.0-RC (2016-07-04)
1.1.3 (2016-06-26)
1.1.2 (2016-05-31)
1.1.1 (2016-05-17)
1.1.0 (2016-05-10)

下载好后把它放到usr/local/bin

2.第二步安装 Laravel
通过 Laravel 安装器安装
首先，通过 Composer 下载 Laravel 安装器。

wangxiong@Dell:~/Soft/laravel$ /usr/local/bin/composer.phar global require "laravel/installer=~1.1"
/usr/bin/env: php: No such file or directory

噢噢,报错了,没有php这个环境变量,那就连接一个php全局变量吧(ln -s)
我的第一次做法,跑到bin目录下

wangxiong@Dell:/www/wdlinux/php/bin$ sudo ln -s php /usr/local/bin

然后又出现了下面的错误

wangxiong@Dell:~/Soft/laravel$ /usr/local/bin/composer.phar global require "laravel/installer=~1.1"
/usr/bin/env: php: Too many levels of symbolic links

嗷嗷,太多的符号连接

网上解释:
ln -s 源文件目标文件
源文件和目标文件没有使用绝对路径导致出错

好吧,放大招了

sudo ln -s /www/wdlinux/php/bin/php /usr/local/bin

老司机开车了

 wangxiong@Dell:~/Soft/laravel$ /usr/local/bin/composer.phar global require "laravel/installer=~1.1"
Changed current directory to /home/wangxiong/.config/composer
./composer.json has been created

Writing lock file
Generating autoload files

最后留意一下安装目录哦~
终端第一句给出了答案~
我的是

/home/wangxiong/.config/composer

最后把vendor/bin这个路径添加到环境变量里

全路径
/home/wangxiong/.config/composer/vendor/bin

打开~/.bashrc

sudo vim ~/.bashrc

添加行：
export PATH=/home/wangxiong/.config/composer/vendor/bin

跑一跑,异常了,oh no

wangxiong@Dell:~/Documents$ laravel new blog
Crafting application...

  [GuzzleHttp\Exception\ConnectException]                              
  cURL error 6: See http://curl.haxx.se/libcurl/c/libcurl-errors.html  

  [GuzzleHttp\Ring\Exception\ConnectException]                         
  cURL error 6: See http://curl.haxx.se/libcurl/c/libcurl-errors.html  


new [--dev] [--] [<name>]

吃了个饭回来,重新开车了

wangxiong@Dell:~/Documents$ laravel new blog
Crafting application...
sh: composer: command not found
Application ready! Build something amazing.

虽然提示了一个命令找不到,但还是启动了,不多说了,看帮我们创建了哪些依赖模板

wangxiong@Dell:~/Documents$ cd blog/
wangxiong@Dell:~/Documents/blog$ ls
app  composer.json  database phpunit.xml  resources   tests  artisan    composer.lock  gulpfile.js   public  server.php
bootstrap  config   package.json  readme.md    storage

如果检测自己是否Laravel安装成功了,跑跑下面的命令

wangxiong@Dell:/usr/local/bin$ php composer.phar 
   ______
  / ____/___  ____ ___  ____  ____  ________  _____
 / /   / __ \/ __ `__ \/ __ \/ __ \/ ___/ _ \/ ___/
/ /___/ /_/ / / / / / / /_/ / /_/ (__  )  __/ /
\____/\____/_/ /_/ /_/ .___/\____/____/\___/_/
                    /_/
Composer version 1.2.0 2016-07-19 01:28:52

Usage:
  command [options] [arguments]

小插曲:
运行 php artisan env查看当前环境时报错

PHP Fatal error:  require(): Failed opening required '/home/wangxiong/Public/workspace_php/my_web/bootstrap/../vendor/autoload.php'

提示少了vendor/autoload.php ,我到项目根目录下一看少了vendor这个文件夹,解决

composer.phar dump-autoload

最后介绍三条重要命令composer dump-autoload, composer update and composer install

    composer install installs the vendor packages 
composer.lock if not present),
    composer update always regenerates composer.lock 
packages based on composer.json

    composer dump-autoload won’t download a thing. It 
to be included in the project (autoload_classmap.php). 
Ideal for when you have a new class inside your 
project.
        Ideally, you execute composer dump-autoload -o 
reason it is not default, is because it takes a bit 
longer to generate (but is only slightly noticable)

ps:如果新建项目的时候,出现连接异常

[GuzzleHttp\Exception\ConnectException]                              
  cURL error 6: See http://curl.haxx.se/libcurl/c/libcurl-errors.html

链接失败,被墙了,可以更改到国内镜像

composer config -g repo.packagist composer https://packagist.phpcomposer.com

http://pkg.phpcomposer.com/
