|
|
安装虚拟机
|
|||
|
|
学习并训练常用的命令符号
|
|||
|
|
|
|||
|
|
第二天
|
|||
|
|
上午
|
|||
|
|
1学习nfs及其他三大服务器配置
|
|||
|
|
2设置共享文件夹
|
|||
|
|
|
|||
|
|
下午
|
|||
|
|
1.配置nfs服务器（资料#4）
|
|||
|
|
2.连接主机与器材
|
|||
|
|
3.gcc -v（检查gcc版本）
|
|||
|
|
晚上
|
|||
|
|
/宿主机和目标机互ping，在SecureCRT上看可不可以查看虚拟机的共享文件
|
|||
|
|
1、将所有的线连接之后
|
|||
|
|
2、把自己电脑的无线网卡禁用
|
|||
|
|
3、把虚拟机选择桥接模式
|
|||
|
|
4、打开SecureCRT 选择seriel，选择com3接口，选择波特率115200，取消勾选Rt。。。
|
|||
|
|
5、在SecureCRT里输入ifconfig，看到设备的ip地址是192.168.1.102
|
|||
|
|
6、在虚拟机输入ifconfig,看到电脑的主机地址是192.168.1.102
|
|||
|
|
7、在虚拟机输入ping 192.168.1.102
|
|||
|
|
8、看到传输过程则ping成功
|
|||
|
|
9、按shift+z退出ping命令
|
|||
|
|
10、在SecureCRT 输入 mount -t nfs -o nolock 192.168.1.103:/home/fang/hello /mnt
|
|||
|
|
11、在SecureCRT 输入 cd /mnt，再输入ls
|
|||
|
|
12、若出现共享文件夹则查看成功

将代码粘贴保存后
|

1编译生成可执行文件:
|

|
|
#gcc –g tst.c –o tst
|
|||
|
|
2启动GDB
|
|||
|
|
#gdb tst
|
|||
|
|
3在main函数处设置断点
|
|||
|
|
(gbd)break main
|
|||
|
|
4运行程序
|
|||
|
|
(gdb)run
|
