linux - Why do I still need to enter a password when NOPASSWD is configured in sudoers?

Question

This is my sudoers configuration file

Defaults        env_reset
Defaults        mail_badpass
Defaults        secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

# Host alias specification
Host_Alias TX=12x.xxx.xxx.xx9

# User alias specification

# Cmnd alias specification

# User privilege specification
root    ALL=(ALL:ALL) ALL
www_remote TX=(root) NOPASSWD:/bin/chown

# Allow members of group sudo to execute any command
%sudo   ALL=(ALL:ALL) ALL

# See sudoers(5) for more information on "#include" directives:

#includedir /etc/sudoers.d

You still need to enter the password when executing sudo chown after logging in to www_remote remotely

[root@VM_xx_xx_centos ~]# sudo -u apache ssh xxx.xxx -l www_remote
Linux iZ...Z 3.2.0-4-amd64 #1 SMP Debian 3.2.86-1 x86_64

www_remote 无权在 iZ281fkjotsZ 上运行 sudo。此事将被报告。

If it is www_remote ALL=(root) NOPASSWD:/bin/chown, the command can be executed normally.

What is wrong with my configuration?

Answer 1

sudo su root

Answer 2

Move the "www_remote" line to the end of the file, otherwise %sudo will overwrite it.
