有時候為了自行安裝最新版Nginx，不想系統裡面自帶的老版本Nginx搗亂，就需要將其刪除。
很多時候機房給配置的機器已經自行安裝了Nginx，版本又很老，運行起來已經占了80埠，很討厭。
下面的方法告訴你如何干淨的刪除HTTP://www.aliyun.com/zixun/aggregation/33836.html">Debian Linux系統下自帶Nginx。
注意先備份/etc/nginx/nginx.conf等檔
cp /etc/nginx/ ~/ -R
apt-get remove –purge nginx
如果報錯，編輯
/var/lib/dpkg/info/nginx.prerm
comment out the line with invoke-rc.d which gives the stop statement for nginx
如果出現無法刪除，那麼刪除:
sudo rm -rf /etc/nginx/
sudo rm -rf /usr/sbin/nginx
sudo rm /usr/share/man/man1/nginx.1.gz
sudo apt-get remove nginx*
