centos上如何配置composer国内镜像

在 CentOS 上配置 Composer 国内镜像，可以加快包的下载速度。以下是具体步骤：

方法一：修改全局配置文件

1. 打开终端。

2. 编辑全局配置文件： 使用文本编辑器（如 vim 或 nano）打开 Composer 的全局配置文件 config.json。

   sudo vim /usr/local/bin/composer
   

   或者

   sudo nano /usr/local/bin/composer
   

3. 添加国内镜像配置： 在文件中找到 storage 部分，如果没有则添加。然后添加以下内容：

   {
       "config": {
           "process-timeout": 1800,
           "storage-dir": "/home/yourusername/.composer",

           "repo-dir": "/home/yourusername/.composer/repo",
           "config-file": "/home/yourusername/.composer/config.json"
       },
