web服务器goahead的移栽

1.网上下载goahead-3.1.1-0-src.tgz包

2.解压

tar -zxvf goahead-3.1.1-0-src.tgz

3.编译

cd goahead-3.1.1-0

make CC=arm-none-linux-gnueabi-gcc ARCH=arm

在linux-arm-default/bin中可以找到goahead

4.测试修改

运行./goahead测试

问题1:

goahead: 0: Can't get host address for host dvr: errno 11
goahead: 0: Can't initialize server. Exiting.

出处:goahead-3.1.1-0\src\http.c文件的setLocalHost函数

    if ((hp = gethostbyname(host)) == NULL) {	//MHB 2013-10-22 出错地方
        error("Can't get host address for host %s: errno %d", host, errno);	//----这
        return -1;
    }
    memcpy((char*) &intaddr, (char *) hp->h_addr_list[0], (size_t) hp->h_length);
	ipaddr = inet_ntoa(intaddr);	//一切的操作目的是获取ipaddr
    websSetIpAddr(ipaddr);			
    websSetHost(ipaddr);

修改: 

#if 0
    if ((hp = gethostbyname(host)) == NULL) {	//MHB 2013-10-22
        error("Can't get host address for host %s: errno %d", host, errno);
        return -1;
    }
    memcpy((char*) &intaddr, (char *) hp->h_addr_list[0], (size_t) hp->h_length);
	ipaddr = inet_ntoa(intaddr);
#else	//MHB 2013-10-22 换种方式获取ip地址 (ipv4)
	int sockfd;	
	struct sockaddr_in sin;	
	struct ifreq ifr;		
	sockfd = socket(AF_INET, SOCK_DGRAM, 0);	
	if (sockfd == -1)	{			
		return -1;			
	}		
	strncpy(ifr.ifr_name, "eth0", IFNAMSIZ);	//网卡多的得修改下
	ifr.ifr_name[IFNAMSIZ - 1] = 0;		
	if (ioctl(sockfd, SIOCGIFADDR, &ifr) < 0)	{			
		return -1;	
	}	
	memcpy(&sin, &ifr.ifr_addr, sizeof(sin));	
	ipaddr=inet_ntoa(sin.sin_addr);	
#endif
    websSetIpAddr(ipaddr);
    websSetHost(ipaddr);

问题2:

goahead: 0: Can't open config file route.txt
goahead: 0: Can't initialize server. Exiting.

解决方法:
拷贝goahead-3.1.1-0\src\route.txt文件到goahead同目录下

问题3:
网页存放位置
解决方法:
存放网页在goahead同目录下的web目录下,web目录手工创建一个便是
