I downloaded and installed composer on the server, and then moved composer.phar to /usr/local/bin/composer
Then I opened the project directory and ran php composer.phar search. Could not open input file appeared : composer.phar,
I also tried other commands, but still got this error.

重命名以后的文件名是composer不是composer.phar直接输入
composer searchcomposer search xxxcomposer.phar是一个打包了的php程序。其实还是一个文件，和其它的php文件一样可以php composer.phar打开，同样也可以./composer.phar。但是你把composer.phar移动到/usr/local/bin去了，而且改了名字composer，所以你可以直接使用composer命令了。至于为什么用php composer.phar不行了，因为你的文件在当前目录没有composer.phar呀。
