Install under Alpine docker and use composer to fill the pit

Question 1: Error Do not run Composer as root/super user!

1. Create a new user and password

    useradd newname
    passwd  123456

2. Switch to a new user account

	su newname

After switching to the new user, you can perform the original operation and successfully complete the composer command.

Create a new user and user group, switch to the new user to execute the corresponding command

Append user to sudo user group

root@centos-system$ sudo usermod -a -G sudo userName

问题二：touch(): Unable to create file /home/composer/.composer/config.json because No such file or directory

Copy or move .composer under the root command to the user directory used to execute composer

sudo mv /root/.composer /home/user1/

Question 3: Could not read /home/user1/.composer/config.json

Authorize the directory

sudo chmod -r 777 /home/user1
