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

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

报错信息

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] socket() [::]:80 failed (97: Address family not supported by protocol)
定位方法

1.先使用ps -e | grep nginx查看是否已经启动了nginx

2.如果没有的话则按照提示，查看0.0.0.0:80端口谁占用了，使用netstat -ltunp命令，可以看到

可以看到0.0.0.0:80端口被httpd这个进程占用了（也就是apcache占用）

关闭httpd服务即可
