nginx重启 failed (98: Address already in use)

centos6.5,启动nginx服务,无法开启,导致网页打不开。把服务从起一下发现提示错误如下:

Starting 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()

问题描述:地址已被使用。可能nginx服务卡死了,导致端口占用,出现此错误。
