Samba源码编译及安装

一 引子

系统是Ubuntu14.04，参考《Ubuntu 14.04 samba安装》http://blog.chinaunix.net/uid-26527046-id-4338338.html，进行samba安装，在Windows 7下访问，却总提示“指定的网络名不再可用”，在另外的Ubuntu机器可以访问，但创建文件虽然成功，但会提示权限问题。

 

“指定的网络名不再可用”的问题，在/var/samba/log/ 下的log文件的显示这样的错误：

在网上查找各种解决方法，都没有用，比如: 检查 ComputerBrowser、Server、Workstation 三个服务

 

最后在samba官网看到，这是samba的一个BUG，有patch可以解决，这样我想，使用SAMBA的最新版本，应该就可以解决了吧。

于是有下面编译安装的过程。

二 编译及安装

1 到https://download.samba.org/pub/samba/stable/下载最新版本源码，我下载的是samba-4.4.3.tar.gz

2 解压，tar -xvf samba-4.4.3.tar.gz

3 安装编译环境及必要的工具：

sudo apt-get install git-core gnupg flexbison gperf build-essential zip curl zlib1g-dev gcc-multilib g++-multiliblibc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev ccachelibgl1-mesa-dev libxml2-utils xsltproc unzip

 

sudo apt-get install python-dev libgnutls-devlibacl1-dev libldap2-dev

4 进入samba-4.4.3目录，开始进行编译:

./configure

make

sudo make install

configure或make过程，如果提示缺什么工具，就需要安装什么工具。

安装目录是在/user/local/samba下，这个目录并没有export出来，继续往下看。

5 卸载apt-get install安装的samba

$sudo apt-get remove samba-common

$sudo apt-get remove samba

6 export samba环境变量

sudo vi /etc/ld.so.conf.d/samba.conf

添加：

/usr/local/samba/lib

 

sudo vi /etc/profile.d/samba.sh

添加：

export PATH=$PATH:/usr/local/samba/bin:/usr/local/samba/sbin

 

sudo vi /etc/sudoers

修改：

Defaults       secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

为

Defaults       secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/samba/bin:/usr/local/samba/sbin"

 

因为这个文件是只读的，要用wq!保存。

7 重启系统，然后用命令smbd –V 查看版本，以确认环境变量是否起作用。

三 Samba配置

新装的samba，跑的配置文件是在/usr/local/samba/etc/目录下，所以需要将smb.conf拷过去。

sudo cp samba-4.4.3/packaging/LSB/smb.conf /usr/local/etc/

sudo vi /usr/local/etc/smb.conf

将workgroup改为：

workgroup = WORKGROUP

 

在文件末尾添加：

[share]

       path= /home/xxx/share

       writeable= yes

       validusers = xxx

 

xxx 是系统的一个用户名，在其HOME目录下需要创建一个share文件夹。

 

添加xxx Samba用户：

sudo smbpasswd –a xxx

按要求输入密码

xxx首先必须是系统用户名称，密码可以不必与系统用户的密码相同。

 

smb.conf修改完毕后保存，然后调用下面命令启动samba服务：

sudo nmbd

sudo smbd

 

然后在Windows进行映射或者网上邻居访问。
