1、下载bugzilla-4.2.tar.gz，解压缩到/var/www/html/目录下
2、进入/var/www/html/目录，执行
#./checksetup.pl --check-modules
如果提示Can't locate ExtUtils/MM.pm,可执行
#yum install mod_perl
或
#yum install perl-CPAN
3、对于没有安装的模块，执行
#./install-module.pl <module-name>
4、配置apache配置文件/etc/httpd/conf/httpd.conf,添加虚拟主机bugzilla.o2o.com
<VirtualHost *:80>
ServerAdmin webmaster@dummy-host.example.com
DocumentRoot /var/www/html/bugzilla-4.2
ServerName bugzilla.o2o.com
ErrorLog logs/bugzilla.o2o.com-error_log
CustomLog logs/bugzilla.o2o.com-access_log common
<Directory /var/www/html/bugzilla-4.2>
AddHandler cgi-script .cgi
Options +Indexes +ExecCGI +FollowSymLinks
DirectoryIndex index.cgi index.html
AllowOverride ALL
#AllowOverride Limit Options FileInfo
AddType application/vnd.mozilla.xul+xml .xul
AddType application/rdf+xml .rdf
</Directory>
</VirtualHost>
6、因为访问的虚拟主机定义了域名，可以修改/etc/hosts文件，添加
127.0.0.1 bugzilla.o2o.com
#AllowOverride Limit Options FileInfo
注：如果访问出现这样的提示.htaccess: ExpiresActive not allowed
here，将AllowOverride Limit Options FileInfo,修改为AllowOverride ALL
