centos下composer两种安装办法

1、下载composer.phar文件

curl -sS https://getcomposer.org/installer | php

将composer.phar移动到环境变量中并且更名为composer

mv composer.phar  /usr/local/bin/composer

使用国内镜像

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

2、

wget https://dl.laravel-china.org/composer.phar -O /usr/local/bin/composer

chmod a+x /usr/local/bin/composer
