1.2.2 installation of various servers

  • NFS services
    Ubuntu / development board, shared file service
  • FTP service
    Ubuntu/Windows, shared file service
  • SSH service
    Remote login to Ubuntu system

Installation command

/*This script will set the original address of software update by default, which can be manually set to 163 software source, which is faster*/
wget --no-check-certificate -O Configuring_ubuntu.sh \
https://weidongshan.coding.net/p/DevelopmentEnvConf/d/DevelopmentEnvConf/git/raw/master/Configuring_ubuntu.sh \
&& sudo chmod +x Configuring_ubuntu.sh && sudo ./Configuring_ubuntu.sh

Installation script, Configuring_ubuntu.sh

  • An error was encountered
Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
  • Solution: delete the process that occupies the file
    Display process
ps -A | grep apt

Close process

sudo kill -9 processnumber

1.2.3 SSH service

  • Start SSH service
sudo /etc/init.d/ssh start
  • View system startup services
/*netstat - atulnp All ports and all corresponding programs will be displayed, and the desired words can be filtered out with grep pipeline*/
sudo netstat -ntlp

1.2.4 NFS service

  • Modify mountd port
book@100ask:~$ sudo vi /etc/services
  • Add two lines
mountd   9999/tcp
mountd   9999/udp
  • Modify nfs configuration file / etc/exports
stay Ubuntu Linux In the system,/etc/exports yes nfs Global profile of the server. A line in the configuration file is a configuration item, which is used to indicate "which clients" in the network share "which directory resources". Add the created shared directory to it, followed by*(rw,sync,no_root_squash,no_subtree_check)parameter
  • restart

Restart rpcbind service and nfs service. nfs is an RPC program. Before using it, you need to map the port and set it through rpcbind

(1)sudo /etc/init.d/rpcbind restart

         [ ok ] Restarting rpcbind (via systemctl): rpcbind.service.
(2)sudo /etc/init.d/nfs-kernel-server restart

         [ ok ] Restarting nfs-kernel-server (via systemctl): nfs-kernel-server.service.

If restarting NFS kernel server (via systemctl) appears: NFS kernel server serviceJob for nfs-server. service canceled

There may be a problem with the file modification. Create a new nsf folder under home according to the above.
