安装MailGraph_ext之前，必须要安装他所依赖的一些软件包，否则MailGraph_ext就不能正常工作。
*rrdtool 及rrdtool的perl包，地址：

*File::Tail (还需要Time::HiRes模块)
复制mailgraph_ext目录到/usr/local/
shell
# cp -r /var/www/extsuite/extman/addon/mailgraph_ext/ /usr/local/mailgraph_ext/
启动mailgraph_ext及cmdserver
shell
# /usr/local/mailgraph_ext/mailgraph-init start
# /var/www/extsuite/extman/daemon/cmdserver –daemon
将MailGraph_ext及cmdserver加入系统自启动
shell
# echo “/usr/local/mailgraph_ext/mailgraph-init start” >> /etc/rc.d/rc.local
# echo “/var/www/extsuite/extman/daemon/cmdserver -v -d” >> /etc/rc.d/rc.local
