[root@localhost nginx-0.7.67]#/usr/local/nginx/sbin/nginx         /启动Nginx   

　　当出现如下情况时：

[root@web2 nginx-0.7.67]# /usr/local/nginx_test/sbin/nginx
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: still could not bind()

　　就要修改nginx的端口或者关掉占用80端口的应用；

修改端口方法：

在 Linux 上该文件的路径下找到  /usr/local/nginx/conf/nginx.conf

server {
	listen       80;
	server_name  localhost;
	
	……
}

　　改为：

server {
	listen       81;
	server_name  localhost;
	
	location / {
		root   html;
		index  index.html index.htm;
	}
	……
}
