centos 如何安装composer

确保安装了php且任意位置可以使用php命令

/usr/local/php/bin/php -v
ln -s /usr/local/php/bin/php /usr/local/bin/php
php -v

下载composer

cd /usr/local/bin/
wget https://getcomposer.org/download/1.8.4/composer.phar
mv composer.phar composer

或

curl -sS https://getcomposer.org/installer | php
mv composer.phar /usr/local/bin/composer

添加可执行全下

chmod +x composer

更换国内镜像

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

centos 不可在root下使用,还需要新增用于

useradd mes
passwd mes
