CPAN是Comprehensive Perl Archive Network的縮寫.。它是一個巨大的Perl軟體收藏庫，收集了大量有用的Perl子產品(modules)及其相關的檔案。如果傳回上述資訊說明系統沒有安裝CPAN子產品。
查詢是否安裝CPAN子產品可以用：[[email protected] bugzilla]# rpm -q perl-CPAN
安裝CPAN指令：[[email protected] bugzilla]#yum -y install perl-CPAN
2：
[[email protected] conf]# service httpd restart
停止 httpd： [确定]
正在啟動 httpd：httpd: apr_sockaddr_info_get() failed for zhm
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
>>>>
主要是ServerName沒有與localhost(即本地127.0.0.1)綁定，解決方法如下：
[[email protected] conf]#vim /etc/httpd/conf/httpd.conf
加入一句 ServerName localhost:80
3：
[[email protected] conf]#/usr/bin/perl install-module.pl XML::Twig
>>>>
一切顯示ok，但是checksetup.pl 查詢時卻顯示未安裝，可進行如下安裝：
/usr/bin/perl -MCPAN -e 'install XML::Twig'
或
perl -MCPAN -e shell
install XML::Twig
或強制安裝
perl -MCPAN -e shell
force install XML::Twig

說明沒有安裝gcc工具
其實判斷是否安裝gcc，最簡單方法是輸入gcc,未安裝的話會顯示指令沒找到,如果安裝了，一般顯示“gcc: 沒有輸入檔案”
如果安裝來gcc則：export CC=gcc
------
安裝gcc:
yum -y install gcc
yum -y install gcc-c++
yum install make
--或者
yum groupinstall "Development Tools"
--或者
yum install gcc gcc-c++ kernel-devel
------

一般這個錯說明apxs沒有安裝。apxs是apache的一個輔助工具軟體，它通常用來為apache安裝擴充子產品，甚至可以直接将.c的源程式自動編譯成.so程式，并能自動配置httpd.conf檔案，将新安裝的擴充添加到配置檔案中啟用。CentOS下安裝httpd的時候，預設是沒有這個工具的。要安裝apxs其實也簡單，隻需要安裝httpd-devel就可以了：
yum install httpd-devel
httpd-devel安裝完成之後，apxs工具預設會安裝在目錄：/usr/sbin/ 裡面。
檢視httpd-devel安裝的軟體相關路徑：rpm -ql httpd-devel
