Makefile:8: recipe for target 'build' failed
make: *** [build] Error 2

　原因，是将警告当成了错误处理，打开./objs/Makefile，

CFLAGS =  -pipe  -O -W -Wall -Wpointer-arith -Wno-unused-parameter -Werror -g (去掉-Werror)
再重新make -j2
-Wall 表示打开gcc的所有警告
-Werror，它要求gcc将所有的警告当成错误进行处理

　

#\cp objs/nginx /usr/local/nginx/sbin/nginx

如果提示“cp:cannot create regular file `/usr/local/nginx/sbin/nginx': Text file busy”

建议使用如下语句cp

#cp -rfp objs/nginx /usr/local/nginx/sbin/nginx
