linux 下80端口被占用

先看报错：

[root@localhost ~]# nginx

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

nginx: [emerg] still could not bind()

解决办法

• netstat -ntlp|grep 80 #发现80端口被一个httpd服务占用了

• kill -9 1890 #杀了2次，每次都会重新启动一个进程 --杀不掉！！

• service httpd.service stop #于是乎停掉这个服务（杀手锏）

• 小样，这回起不来了吧

• 于是重启nginx --ok，大功告成！
