#!/bin/sh

EXPECTED_CHECKSUM="$(wget -q -O - https://composer.github.io/installer.sig)"
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
ACTUAL_CHECKSUM="$(php -r "echo hash_file('sha384', 'composer-setup.php');")"

if [ "$EXPECTED_CHECKSUM" != "$ACTUAL_CHECKSUM" ]
then
    >&2 echo 'ERROR: Invalid installer checksum'
    rm composer-setup.php
    exit 1
fi

php composer-setup.php --quiet
RESULT=$?
rm composer-setup.php
exit $RESULT

执行

1
2
chmod a+x install.sh
./install.sh

执行之后会看到本地目录下载好了composer.phar,
然后执行

1
mv composer.phar /usr/local/bin/composer

使得composer可以在任意目录使用，这样就安装完成了。

敲入composer命令，或者composer -V来确认composer是否安装成功。

2. PHPStorm配置Composer
