Kerberos初体验--安装。

OS： Centos 6.3 final

1, 下载Kerberos

     krb5-1.6.3.tar.gz

2, 编译原码

将krb5-1.6.3.tar.gz 使用 ftp传输到linux 机器。使用root用户；

解压缩，执行 configure和make

$ tar zxvf krb5-1.6.3.tar.gz

$cd krb5-1.6.3/src

$./configure

$make

$make install

缺省的将 kerberos安装在/usr/local 目录下；主要包括 /usr/local/sbin、/usr/local/bin 、/usr/local/man、 /usr/local/lib等目录。

Q&A

Q1 执行./configure报错

configure: error: Could not find tgetent; are you missing curses/ncurses library?

configure: error: /bin/sh './configure' failed for telnet
configure: error: /bin/sh './configure' failed for appl

检查ncurses是否安装：

rpm -qa | grep ncurses

[root@localhost src]# rpm -qa | grep ncurses
ncurses-base-5.7-3.20090208.el6.x86_64
ncurses-libs-5.7-3.20090208.el6.x86_64
ncurses-5.7-3.20090208.el6.x86_64

A1：

这是因为没有安装ncurse-devel的原因，执行yum安装:

yum install ncurse-devel

此时可能会报错：

[root@localhost src]# yum install ncruses-devel
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile
* base: mirrors.tuna.tsinghua.edu.cn
* extras: mirrors.tuna.tsinghua.edu.cn
* updates: mirrors.tuna.tsinghua.edu.cn
Setting up Install Process
No package ncruses-devel available.
Error: Nothing to do
[root@localhost src]#

说明，yum的resposity中没有包含需要的rpms(RPM Package Manager files)，所以这里我们需要添加附加包--RPMforge repository. 

下载地址：http://wiki.centos.org/AdditionalResources/Repositories/RPMForge?action=show&redirect=Repositories%2FRPMForge#head-b06dd43af4eb366c28879a551701b1b5e4aefccd

当前我的系统为Cento 6.3 x86_64，所以下载http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm

wget http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm

接着，执行如下命令：

Install DAG's GPG key

rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt

If you get an error message like the following the key has already been imported:

error: http://apt.sw.be/RPM-GPG-KEY.dag.txt: key 1 import failed.

Verify the package you have downloaded

rpm -K rpmforge-release-0.5.3-1.el6.rf.*.rpm

Install the package

rpm -i rpmforge-release-0.5.3-1.el6.rf.*.rpm

好，到这里可以再次执行yum install ncurse-devel了
