linux中如何批量管理用户和组？这篇文章运用了实例代码展示，代码非常详细，可供感兴趣的小伙伴们参考借鉴，希望对大家有所帮助。
使用/etc/sudoers里设置用户别名、命令别名来设置各个用户类型所需要的权限和命令来控制用户权限和所能使用的命令
主机别名# Host_Alias FILESERVERS = fs1, fs2
用户别名
组别名
# User_Alias ADMINS = jsmith, mikem
# User_alias AdminsGroup=%xbin命令别名# Cmnd_Alias SOFTWARE = /bin/rpm, /usr/bin/up2date, /usr/bin/yum
配置
用户 主机=(主机) 命令
root ALL=(ALL) ALL
sudoers文件配置
[root@xbin-S ~]# grep -v "##" /etc/sudoers
# Host_Alias FILESERVERS = fs1, fs2
# Host_Alias MAILSERVERS = smtp, smtp2
# User_Alias ADMINS = jsmith, mikem
# Cmnd_Alias NETWORKING = /sbin/route, /sbin/ifconfig, /bin/ping, /sbin/dhclient, /usr/bin/net, /sbin/iptables, /usr/bin/rfcomm, /usr/bin/wvdial, /sbin/iwconfig, /sbin/mii-tool
# Cmnd_Alias SOFTWARE = /bin/rpm, /usr/bin/up2date, /usr/bin/yum
# Cmnd_Alias SERVICES = /sbin/service, /sbin/chkconfig
# Cmnd_Alias LOCATE = /usr/bin/updatedb
# Cmnd_Alias STORAGE = /sbin/fdisk, /sbin/sfdisk, /sbin/parted, /sbin/partprobe, /bin/mount, /bin/umount
# Cmnd_Alias DELEGATING = /usr/sbin/visudo, /bin/chown, /bin/chmod, /bin/chgrp
# Cmnd_Alias PROCESSES = /bin/nice, /bin/kill, /usr/bin/kill, /usr/bin/killall
# Cmnd_Alias DRIVERS = /sbin/modprobe
# Defaults specification
#
# Refuse to run if unable to disable echo on the tty.
#
Defaults !visiblepw
#
# Preserving HOME has security implications since many programs
# use it when searching for configuration files. Note that HOME
# is already set when the the env_reset option is enabled, so
# this option is only effective for configurations where either
# env_reset is disabled or HOME is present in the env_keep list.
#
Defaults always_set_home
Defaults env_reset
Defaults env_keep = "COLORS DISPLAY HOSTNAME HISTSIZE INPUTRC KDEDIR LS_COLORS"
Defaults env_keep += "MAIL PS1 PS2 QTDIR USERNAME LANG LC_ADDRESS LC_CTYPE"
Defaults env_keep += "LC_COLLATE LC_IDENTIFICATION LC_MEASUREMENT LC_MESSAGES"
Defaults env_keep += "LC_MONETARY LC_NAME LC_NUMERIC LC_PAPER LC_TELEPHONE"
Defaults env_keep += "LC_TIME LC_ALL LANGUAGE LINGUAS _XKB_CHARSET XAUTHORITY"
#
# Adding HOME to env_keep may enable a user to run unrestricted
# commands via sudo.
#
# Defaults env_keep += "HOME"
Defaults secure_path = /sbin:/bin:/usr/sbin:/usr/bin
root ALL=(ALL) ALL
xbin ALL=(ALL) ALL
# %sys ALL = NETWORKING, SOFTWARE, SERVICES, STORAGE, DELEGATING, PROCESSES, LOCATE, DRIVERS
# %wheel ALL=(ALL) ALL
# %wheel ALL=(ALL) NOPASSWD: ALL
# %users ALL=/sbin/mount /mnt/cdrom, /sbin/umount /mnt/cdrom
# %users localhost=/sbin/shutdown -h now
#includedir /etc/sudoers.d
Defaults logfile=/var/log/sudo.log实战命令
