![启动nginx报错：[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)](http://www.mshxw.com/aiimages/31/850808.png "启动nginx报错：[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)")
问题描述：以前能启动的nginx忽然无法启动，报错[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)。csdn上找了一圈方法试下来都不行。
解决方法：
sudo fuser -k 80/tcp
会跳出来一堆permission deny，但是nginx可以启动了
