非root用户有时需要执行root才能执行的命令，可以通过配置sudoers文件实现

修改sudoers文件

vim /etc/sudoers

增加user1

user1    ALL=(ALL:ALL) ALL

# This file MUST be edited with the 'visudo' command as root.
#
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.
#
# See the man page for details on how to write a sudoers file.
#
Defaults        env_reset
Defaults        mail_badpass
Defaults        secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin"

# Host alias specification

# User alias specification

# Cmnd alias specification

# User privilege specification
root    ALL=(ALL:ALL) ALL
user1    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

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

#includedir /etc/sudoers.d

如果sudoers文件为readonly，提示无法修改

E45: 'readonly' option is set (add ! to override)

修改文件读写权限

chmod 660 /etc/sudoers

root@:~# ls -al  /etc/sudoers
-rw-rw---- 1 root root 781 Sep 24 13:58 /etc/sudoers

修改文件读写

E45: 'readonly' option is set (add ! to override)
