Ubuntu下切换用户免密与smb挂载开启

切换用户免密设置

有时候自己在虚拟机中使用Ubuntu，每次需要root权限时切换用户都显得挺麻烦，可以通过修改配置文件来让每次切换时不用输入密码。

root@server:~# vim /etc/sudoers## 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_resetDefaults        mail_badpassDefaults        secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"# Host alias specification# User alias specification# Cmnd alias specification# User privilege specificationroot    ALL=(ALL:ALL) ALLtest ALL=(ALL:ALL) NOPASSWD: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

把下面这两行注释掉，然后重启就可以了。

# 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

添加samba挂载

root@server:~# vim /etc/samba/smb.conf

#======================= Share Definitions =======================# Un-comment the following (and tweak the other settings below to suit)# to enable the default home directory shares. This will share each# user's home directory as \\server\username[homes]   comment = Home Directories   browseable = no# By default, the home directories are exported read-only. Change the# next parameter to 'no' if you want to be able to write to them.   read only = no# File creation mask is set to 0700 for security reasons. If you want to# create files with group=rw permissions, set next parameter to 0775.   create mask = 0700# Directory creation mask is set to 0700 for security reasons. If you want to# create dirs. with group=rw permissions, set next parameter to 0775.   directory mask = 0700# By default, \\server\username shares can be connected to by anyone# with access to the samba server.# Un-comment the following parameter to make sure that only "username"# can connect to \\server\username# This might need tweaking when using external authentication schemes   valid users = %S

把/etc/samba/smb.conf文件中的这部分注释去掉，如上所示，然后保存。再添加一个用户 sampasswd -a test，会提示输入密码，如test，然后再重启smb服务：service smbd restart。

然后win+R打开运行窗口，输入:\\ip\test就可以看到提示输入用户名和密码，输入test, test就可以进入samba共享目录了。
