Answer:
Explanation:
See the solution below in Explanation.
Explanation:
Solution:
groupadd ops
visudo -f /etc/sudoers.d/ops-restart-httpd
Add this line to the file:
%ops ALL=(ALL) NOPASSWD: /usr/bin/systemctl restart httpd
Set correct permissions:
chmod 440 /etc/sudoers.d/ops-restart-httpd
visudo -cf /etc/sudoers.d/ops-restart-httpd
Detailed Explanation:
* Using /etc/sudoers.d/ is the standard safe approach.
* visudo validates syntax and helps prevent syntax errors.
* %ops applies the rule to the whole group.
