80 端口被占用

• 有可能是 apchae2 占用的, 所以可以尝试

  sudo service apache2 stop
  sudo systemctl restart nginx
  sudo systemctl status nginx

sudo apt-get --purge remove nginx
# 自动移除全部不使用的软件包
sudo apt-get autoremove
# 罗列出与nginx相关的软件
dpkg --get-selections|grep nginx

# 删除上步中查询到的软件, 如:
sudo apt-get --purge remove nginx
sudo apt-get --purge remove nginx-common
sudo apt-get --purge remove nginx-core

# 查看nginx正在运行的进程，如果有就kill掉
ps -ef |grep nginx
