我自己当时养的一棵盆栽已经送给了庆庆,这棵盆栽不是我养的但办公室另一个团队走了之后我就成了他的继父。

Running a command with substitute user is the typical use of command su
under linux.
Sometimes, use -s
option to running the specified shell instead of the default, this option may helps a lot when need to access user whose default shell is /sbin/nologin
, usage like su -s /bin/bash jenkins
/ets/sudoers
configure user(s) who can get root privileges under linux.
440 permission is on this file by default, so chmod +w
operation is required before modify file, don't forget chmod -w
once modified.
Some typical configs are as follow:
allow jenkins user restart uwsgi service via systemd:
jenkins ALL = NOPASSWD : /bin/systemctl restart uwsgi
explain:
user host = need passwd?: command 1, shell 2, ...
allow moon user access sudo privileges unconditional:
moon ALL=(ALL) NOPASSWD: ALL
