samba配置問題,麻煩幫看看那錯了

我的機器裝的是 linux 5。現在配置samba服務。我的SMB.CONF文件內容是這樣的。
我想共享的文件夾是 /hdata/share,/hdata/mdata ,/hdata/rdata。
但現在的問題是能進入到/hdata里看到三個文件夾,但進不去,雙擊就提示無法訪問,沒有許可權。
我是用useradd ****添加用戶,然後用smbpasswd ****的SMB用戶密碼的。然後把用戶的目錄設成/hdata的。
這是怎麼回事呢。謝謝


# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# For a step to step guide on installing, configuring and using samba,
# read the Samba-HOWTO-Collection. This may be obtained from:
#  http://www.samba.org/samba/docs/Samba-HOWTO-Collection.pdf
#
# Many working examples of smb.conf files can be found in the
# Samba-Guide which is generated daily and can be downloaded from:
#  http://www.samba.org/samba/docs/Samba-Guide.pdf
#
# Any line which starts with a ; (semi-colon) or a # (hash)
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
#
# NOTE: Whenever you modify this file you should run the command "testparm"
# to check that you have not made any basic syntactic errors.
#
#======================= Global Settings =====================================


# workgroup = NT-Domain-Name or Workgroup-Name, eg: MIDEARTH
   workgroup = WORKGROUP

# server string is the equivalent of the NT Description field
   server string = H Server

# Security mode. Defines in which mode Samba will operate. Possible
# values are share, user, server, domain and ads. Most people will want
# user level security. See the Samba-HOWTO-Collection for details.
   security = user

encrypt passwords = yes
smb passwd file = /etc/samba/smbpasswd

# This option is important for security. It allows you to restrict
# connections to machines which are on your local network. The
# following example restricts access to two C class networks and
# the "loopback" interface. For more examples of the syntax see
# the smb.conf man page
   hosts allow = 10.132.80.

# If you want to automatically load your printer list rather
# than setting them up individually then you'll need this
   load printers = yes

;   printcap name = /etc/printcap

# on SystemV system setting printcap name to lpstat should allow
# you to automatically obtain a printer list from the SystemV spool
# system
;   printcap name = lpstat

# It should not be necessary to specify the print system type unless
# it is non-standard. Currently supported print systems include:
# bsd, cups, sysv, plp, lprng, aix, hpux, qnx
;   printing = cups

# This option tells cups that the data has already been rasterized
cups options = raw

# Uncomment this if you want a guest account, you must add this to /etc/passwd
# otherwise the user "nobody" is used
;  guest account = pcguest

# this tells Samba to use a separate log file for each machine
# that connects
   log file = /var/log/samba/%m.log

# Put a capping on the size of the log files (in Kb).
   max log size = 50

# Use password server option only with security = server
# The argument list may include:
#   password server = My_PDC_Name
# or to auto-locate the domain controller/s
#   password server = *
;   password server = <NT-Server-Name>

# Use the realm option only with security = ads
# Specifies the Active Directory realm the host is part of

# use either tdbsam or ldapsam. smbpasswd is available for backwards
# compatibility. tdbsam requires no further configuration.

# Using the following line enables you to customise your configuration
# on a per machine basis. The %m gets replaced with the netbios name
# of the machine that is connecting.
# Note: Consider carefully the location in the configuration file of
#       this line.  The included file is read at that point.

# If you have multiple network interfaces then you must list them
# here. See the man page for details.

# Browser Control Options:
# set local master to no if you don't want Samba to become a master
# browser on your network. Otherwise the normal election rules apply
;   local master = no

# OS Level determines the precedence of this server in master browser
# elections. The default value should be reasonable
;   os level = 33

# Domain Master specifies Samba to be the Domain Master Browser. This
# allows Samba to collate browse lists between subnets. Don't use this
# if you already have a Windows NT domain controller doing this job
;   domain master = yes

# Preferred Master causes Samba to force a local browser election on startup
# and gives it a slightly higher chance of winning the election
;   preferred master = yes

# Enable this if you want Samba to be a domain logon server for
# Windows95 workstations.
;   domain logons = yes

# if you enable domain logons then you may want a per-machine or
# per user logon script
# run a specific logon batch file per workstation (machine)
;   logon script = %m.bat

;   logon script = %U.bat

;   wins server = w.x.y.z

# behalf of a non WINS capable client, for this to work there must be
# at least one        WINS Server on the network. The default is NO.
;   wins proxy = yes

# DNS Proxy - tells Samba whether or not to try to resolve NetBIOS names
# via DNS nslookups. The default is NO.

《解決方案》

應該是SELinux問題。
chcon -R -t samba_share_t /hdata
《解決方案》

如果不是selinux的問題,就是目錄本身許可權的問題。
《解決方案》

嗯,樓上分析的甚是。
《解決方案》

回復 #1 cguzh 的帖子

執行testparm
確認與selinux 許可權無關

謝謝,我運行你的chcon -R -t samba_share_t /hdata 但提示沒有samba_share_t 文件夾。
怎麼回事呢。
謝謝。能幫我說的詳細點嗎?

我把HDATA目錄的讀寫許可權已經付給了我創建的用戶了啊。rdata,mdata,share的許可權也都付給了我創建的用戶了啊
謝謝

注意chcon -R -t samba_share_t與/hdata中間是有空格的。
這個是修改/hdata文件夾的type類型。

謝謝。我後來也這樣執行了。/hdata/share等3個文件夾可以進入了,但沒法創建新文件和刪除。

我也運行了setsebool -P samba_enable_home_dirs=1
但還是不行。

我上網也查了
「RHEL5中的samba伺服器啟動后,能看到共享目錄,但是不能訪問共享目錄,告知許可權不夠。此時可以通過如下命令:

tail /var/log/message看到如此提示:


'/home/lyy' does not exist or permission denied when connecting to Error was 許可權不夠


SELinux is prEVEnting the samba daemon from reading users home directories.For complete SELinux messages. run sealert -l a0c1c154-bc37-44f5-a6eb-cfc88fed18b9


根據提示運行:

sealert -l a0c1c154-bc37-44f5-a6eb-cfc88fed18b9


可看到另外更詳細的提示,再根據提示


Allowing Access

If you want samba to share home directories you need to turn on the

samba_enable_home_dirs boolean: "setsebool -P samba_enable_home_dirs=1"

The following command will allow this access:

setsebool -P samba_enable_home_dirs=1


運行:

setsebool -P samba_enable_home_dirs=1


但我的/var/log/message沒有,只有messages我運行了,可出來的和它的不一樣。
