Linux 用户 sudo 免密码

1. 设置sudoers用户列表

# User privilege specification
root    ALL=(ALL:ALL) ALL
# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL
# Allow members of group sudo to execute any command
%sudo   ALL=(ALL:ALL) ALL
#下面的user是你的用户名 添加这一行就能免密sudo了
user ALL=(ALL:ALL) NOPASSWD: ALL
