at the first,

record this:

root@xxx:~/hexo# hexo server
[error] Error: listen EADDRINUSE

because i modify the hexo default port 4000 to 80 with config file _config.yml

port 80 is used other application,

so

find the process and kill it

the command:

root@xxxxx:~/hexo# fuser -n tcp 80
80/tcp:                705   715   716   717   718
root@xxxxx:~/hexo# kill 705

then generate and start hexo

root@xxxxx:~/hexo# hexo generate
