The following tutorial column of composer will introduce you to the two methods of composer installation. I hope it will be helpful to friends in need!

##Two ways to install composer

Partial installation (valid only in specific projects)

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

//If various errors occur when running the above command, you can also run the following command

php -r "readfile('https://getcomposer.org/installer');" | php

Use –install-dir= ” to specify the installation directory of composer

curl -sS https://getcomposer.org/installer | php -- --install-dir=bin

Global installation (can take effect anywhere on the machine)

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

If composer still cannot be installed anywhere For local execution, you need to add environment variables as follows:

vi /etc/profile 
export PATH=/usr/local/php5.6/bin/:/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin
source /etc/profile (or environment) # 让环境变量立即生效
