git init can't run in /var/www/html/wp
I do as Ding says in the web.
usermod -a -G www-data username
usermod -a -G www-data debian8
It takes no effect at all.
Why can't I run git init in my /var/www/html/wp?

You can also change the umask in your .profile in your home directory:
# the default umask is set in /etc/profile; for setting the umask
# for ssh logins, install and configure the libpam-umask package.
# umask 022
umask 002
What this does is set the initial perms for any new directories or files that you create.
New directories will get 775 (drwxrwxr-x), vs default 755 (drwxr-xr-x). Files will get 664 (-rw-rw-r--), vs default 644 (-rw-r--r--).
Depending on your situation, you may want to change it back after running git init.
