open() “/usr/local/nginx/logs/access.log“ failed (21: Is a directory)nginx: configuration file /us

 open() "/usr/local/nginx/logs/access.log" failed (21: Is a directory)
nginx: configuration file /usr/local/nginx/conf/nginx.conf test failed

是说这个access是一个目录，需要进入这个logs目录把这个access.log删除，使用命令

rm -rf access.log ,有时候权限不够，需要su root ，删除完成之后，使用touch access.log创建

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

被占用，ps -ef |grep nginx查看nginx的进程

使用kill -9  xxx 杀死进程进程即可
