apt-get update&&apt-get upgrade

1
apt-get -y purge apache2-* bind9-* xinetd samba-* nscd-* portmap sendmail-* sasl2-bin

1
apache2-* //apache服务器,一般我们自己会用一键安装包安装
2
bind9-* //我们不需要用VPS搭建DNS,所以去掉
3
xinetd //xinetd是服务守护进程
4
samba-* //samba能让linux使用windows共享功能，不需要
5
nscd-* //DNS缓存软件，同bind9，不需要
6
portmap //端口转发，一般Web服务器不需要
7
sendmail-* //发送邮件用，如果有需要保留
8
sasl2-bin //一个权限程序，占用资源，删除

apt-get -y purge lynx memtester unixodbc python-* odbcinst-* sudo tcpdump ttf-*
