Nginx重启时提示"nginx: [emerg] bind() to 0.0.0.0"解决方法

昨天下午老蒋在一台服务器中折腾迁移数据问题的时候，重启Nginx的时候有发现"Starting nginx... nginx: [emerg] bind() to 0.0.0.0:888 failed (98: Address already in use)"这样的报错问题。

Starting nginx... nginx: [emerg] bind() to 0.0.0.0:888 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 0.0.0.0:888 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 0.0.0.0:888 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 0.0.0.0:888 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 0.0.0.0:888 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()
failed

估摸着是在操作的时候忘记关闭Nginx导致启动冲突，这里要禁止掉端。

sudo fuser -k 80/tcp

最后我们再重启Nginx后显示正常：

/etc/init.d/nginx restart
