freebsd sudo配置使用

首先第一步当然是安装sudo

安装好了之后会产生一个sudoers文件

如果你的sudo安装在/usr/bin/sudo下面的话，sudoers文件可能就在/etc/下面

如果你的sudo安装在/usr/local/bin/sudo下面，sudoers文件在/usr/local/etc/下面

把sudo配置成所有的wheel组可以使用

# sudoers file.

#

# This file MUST be edited with the 'visudo' command as root.

# Failure to use 'visudo' may result in syntax or file permission errors

# that prevent sudo from running.

#

# See the sudoers man page for the details on how to write a sudoers file.

# Host alias specification

# User alias specification

# Cmnd alias specification

# Defaults specification

# Uncomment if needed to preserve environmental variables related to the

# FreeBSD pkg_* utilities and fetch.

#Defaults       env_keep += "PKG_PATH PKG_DBDIR PKG_TMPDIR TMPDIR PACKAGEROOT PACKAGESITE PKGDIR FTP_PASSIVE_MODE"

# Additionally uncomment if needed to preserve environmental variables

# related to portupgrade.

#Defaults       env_keep += "PORTSDIR PORTS_INDEX PORTS_DBDIR PACKAGES PKGTOOLS_CONF"

# Runas alias specification

# User privilege specification

root    ALL=(ALL) ALL

# Uncomment to allow people in group wheel to run all commands

# %wheel        ALL=(ALL) ALL

# Same thing without a password

%wheel  ALL=(ALL) NOPASSWD: ALL

# Samples

# %users  ALL=/sbin/mount /cdrom,/sbin/umount /cdrom

# %users  localhost=/sbin/shutdown -h now

另外,如果想把一个组也能用sudo，需要修改 /etc/group ，把wheel那行进行修改：

e.g:

wheel:*:0:root,lxh,lixh

这样归属lxh，lixh组的都可以使用sudo了
