1.先執行一下命令：

sudo apt-get --purge remove nginx

sudo apt-get autoremove

dpkg --get-selections|grep nginx

羅列出與nginx相關的軟體， nginx-common deinstall 然後

sudo apt-get --purge remove nginx-common

這樣就可以完全解除安裝掉nginx包括配置檔案

2.ps -ef |grep nginx 看下nginx還有沒有啟動,一般執行完1後，nginx還是啟動著的，如下：

[email protected]:/$ ps -ef |grep nginx

root     4061  2418  0 Mar11 ?        00:00:00 nginx: master processsbin/nginx

nobody   4062  4061  0 Mar11 ?        00:00:00 nginx: worker process

bkxmgx  15487  4229  0 01:13 pts/0    00:00:00 grep --color=auto nginx

3.kill   nginx程序

sudo kill -9  4061  4062

4.sudo  find  / -name  nginx*

/usr/local/src/nginx-1.7.9

/usr/local/src/nginx-1.7.9/objs/src/core/nginx.o

/usr/local/src/nginx-1.7.9/objs/nginx.8

/usr/local/src/nginx-1.7.9/objs/nginx

/usr/local/src/nginx-1.7.9/src/http/modules/perl/nginx.xs

/usr/local/src/nginx-1.7.9/src/http/modules/perl/nginx.pm

/usr/local/src/nginx-1.7.9/src/core/nginx.c

/usr/local/src/nginx-1.7.9/src/core/nginx.h

/usr/local/src/nginx-1.7.9/man/nginx.8

/usr/local/src/nginx-1.7.9/conf/nginx.conf

/usr/local/src/nginx-1.7.9/contrib/vim/syntax/nginx.vim

/usr/local/src/nginx-1.7.9/contrib/vim/ftdetect/nginx.vim

/usr/local/src/nginx-1.7.9/contrib/vim/indent/nginx.vim

/usr/local/nginx

/usr/local/nginx/logs/nginx.pid

/usr/local/nginx/conf/nginx.conf.default

/usr/local/nginx/conf/nginx.conf

/usr/local/nginx/sbin/nginx

/home/bkxmgx/nginx.conf

/home/bkxmgx/nginx-1.7.9.tar.gz

/home/bkxmgx/桌面/nginx.conf

/home/bkxmgx/桌面/nginx~

/home/bkxmgx/桌面/nginx

5.依依刪除4列出的所有檔案

sudo rm  -r  /usr/local/src/nginx-1.7.9

sudo rm  -r  /usr/local/nginx

sudo rm  -r  /usr/local/nginx/logs/nginx.pid

sudo rm  -r  /usr/local/nginx/conf/nginx.conf.default

sudo rm  -r  /usr/local/nginx/conf/nginx.conf

sudo rm  -r  /usr/local/nginx/sbin/nginx

sudo rm  -r  /home/bkxmgx/nginx.conf

sudo rm  -r  /home/bkxmgx/桌面/nginx.conf

sudo rm  -r  /home/bkxmgx/桌面/nginx~

sudo rm  -r  /home/bkxmgx/桌面/nginx

這樣就徹底刪除nginx了
