nginx安装出现:cp: `conf/koi-win' and `/application/nginx-1.6.3/conf/koi-win' are the same file

nginx编译安装时make出现如下错误

make[]: Leaving directory `/application/nginx-1.6.'
make -f objs/Makefile install
make[]: Entering directory `/application/nginx-1.6.'
test -d '/application/nginx-1.6.3' || mkdir -p '/application/nginx-1.6.3'

cp objs/nginx '/application/nginx-1.6.3/sbin/nginx'

cp conf/koi-win '/application/nginx-1.6.3/conf'

cp: `conf/koi-win' and `/application/nginx-1.6.3/conf/koi-win' are the same file

这两行告诉你是个已经存在的目录（文件夹），因此无法复制 objs/nginx 文件过去。

多半是环境问题，若是测试机器，不妨移走 /usr/local/nginx 试一下。或用干净的系统再试。
