Build an NFS server on the Ros host
1. The robot side (execution on the server side:)
1. Install the necessary packages
Install the nfs server in the robot
sudo apt-get update
sudo apt-get install nfs-kernel-server
2. Create a directory folder to share
Create a folder for client remote access, such as our commonly used robot code snippets, etc.
sudo -p mkdir /mnt3. Edit the configuration file
①Add NFS shared directory
sudo nano /etc/exports
# 在文件的末尾输入自定义需要共享的文件夹路径
/home/xxx/mnt *(rw,sync,no_root_squash) Parameter introduction : * means that any network segment can be accessed, sync means that the data is synchronously written to the hard disk and memory, no_root_squash means that it has super user privileges
②Set permissions for the mounted directory and modify the file user
sudo chmod -R 777 /home/xxx/mnt
sudo chown -R 777 nobody /home/xxx/mnt # 将指定文件的拥有者是组改为指定的用户或者组4. Start the service
sudo /etc/init.d/nfs-kernel-server start
sudo /etc/init.d/nfs-kernel-server restart
# 先启动NFS再重启NFSSecond, the virtual machine (client)
1. Install nfs-common and portma packages
sudo apt-get install nfs-common portmap2. Create a directory that provides mounting
sudo mkdir /mnt3. Mount
sudo mount -t nfs -o nolock 192.168.0.100:/home/xxx/xxx /mnt
# mount 是挂载的指令，-t 指定文件的类型，-t nfs 就是指定文件网络这个类型，
# 192.168.0.100 机器人的ip地址，后面是机器人路径和挂载的路径
4. Check whether the mount is successful
cd mnt
ls
# 或者使用 df -h指令来查看系统硬盘情况。3. Introduction to nfs related documents
/etc/exports Main configuration files
/etc/usr/exports File system maintenance commands
/var/lib/nfs/*tab Login documents for shared resources
