Mounting an ISO with sys/mount.h

问题 I'm trying to mount an ISO file in a C++ program in linux I'm aware of the linux command to achieve this, i.e mount -o loop ~/Test.iso /mnt/myISO But the mount(2) man page states the following prototype for mounting : int mount(const char *source, const char *target, const char *filesystemtype, unsigned long mountflags, const void *data); How do I specify the loop option here ? -- Also, is it good (/acceptable) practice in general, in linux programming to use system shell calls from C++ to

How to make a system call remotely?

由 ╄→尐↘猪︶ㄣ 提交于 2020-03-10 05:22:01
问题 I have an app that has to mount a disk on a server. The disk and the server all connected, it just has to use the linux 'mount' command. I wrote a php that is simply: <? exec("/var/www/MountTheDisk.sh"); ?> And I added bash script: MountTheDisk.sh #!/bin/bash diskutil mount /dev/xvdb1 /mnt/theDisk/ echo trying to mount Now, if I run that php, I get no result. Nothing is echo'd and no disk is mounted. How can I run this command remotely? Maybe php is not the best method? 回答1: This solution

服务器：192.168.20.204 客户端：192.168.20.203 1. 在服务器配置/etc/export 添加可以共享的文件夹和允许的客户端地址 /home/dir 192.168.20.203(rw,no_root_squash,async) 要加上no_root_squash,async，不然会出现reason given by server: Permission denied 重启nfs服务器 service nfs restart 2. 在客户端运行 mkdir -p /mnt/dir 创建挂载点 mount -t nfs 192.168.20.204:/home/dir /home/dir 一定要先创建挂载点，不然会出现mount point does not exist的错误 3. RPC Error: Program not registered错误 服务没启动。。 运行service nfs restart 来源： https://www.cnblogs.com/ruiy/p/nfs.html

mount nfs的可选参数

由 谁都会走 提交于 2020-03-06 10:38:40
mount nfs的可选参数： HARD mount和SOFT MOUNT： HARD:NFS CLIENT会不断的尝试与SERVER的连接（在后台，不会给出任何提示信息,在LINUX下有的版本仍然会给出一些提示），直到MOUNT上。 SOFT:会在前台尝试与SERVER的连接，是默认的连接方式。当收到错误信息后终止mount尝试，并给出相关信息。 例如： #mount -t nfs -o hard 192.168.0.10:/nfs /nfs 对于到底是使用hard还是soft的问题，这主要取决于你访问什么信息有关。例如你是想通过NFS来运行X PROGRAM的话，你绝对不会希望由于一些意外的情况（如网络速度一下子变的很慢，插拔了一下网卡插头等）而使系统输出大量的错误信息，如果此时你用的是HARD方式的话，系统就会等待，直到能够重新与NFS SERVER建立连接传输信息。另外如果是非关键数据的话也可以使用SOFT方式，如FTP数据等，这样在远程机器暂时连接不上或关闭时就不会挂起你的会话过程。 rsize和wsize： 文件传输尺寸设定：V3没有限定传输尺寸，V2最多只能设定为8k，可以使用-rsizeand -wsize 来进行设定。这两个参数的设定对于NFS的执行效能有较大的影响 bg：在执行mount时如果无法顺利mount上时
