【linux命令】在Linux （centos）中全局安装php工具 composer

[[email protected] ~]# curl -sS /d/file/p/20221029/installer | php
All settings correct for using Composer
Downloading 1.2.2...

Composer successfully installed to: /root/composer.phar
Use it: php composer.phar

2，移动命令至/usr/local/bin/或设置path都可以。
我们这里采用移动文件至/usr/local/bin/：

[[email protected] ~]# mv  composer.phar   /usr/local/bin/composer
[[email protected] ~]# composer  -V
Do not run Composer as root/super user! See /d/file/p/20221029/how-to-install-untrusted-packages-safely.md for details
Composer version 1.2.2 2016-11-03 17:43:15

也可以尝试composer.phar 改名以后将所在路径设置到/etc/profile。看个人习惯。
