1. Create an account
First create an account:
Useraddxxx #xxx为用户名
passwd xxx
Then CD to the NIS environment directory, perform make, synchronize other node accounts
Cd/var/yp
Make
This is the account that is available for all compute nodes
Implement SSH without password login (if required):
Switch to XXX account:
Su xxx
ssh-keygen-t RSA #回车三次
Ssh-copy-id localhost #回车输入密码即可

One of the great benefits of replacing real functions with macro substitution is that macro substitution increases the speed of the code because there is no overhead for function calls. But the increase in speed also has a price: due to repeated coding and increase the length of the program.

"Common sense" with regard to preprocessing
Preprocessing is not a compilation, nor is it "precompiled."
Preprocessing is not available in every language.
The pre-and C + + preprocessing simply divides the source program into segments (phase) and does not compile.
The preprocessor is typically abbreviated as PP in Unix tradition, and in an automated build script the C preprocessor is abbreviated as a macro reference for CPP. In order not to cause ambiguity, C + + (C-plus-plu

A wireless switch can transmit data between multiple port pairs at the same time. Each port can be considered as an independent network segment, and the network devices connected to it can enjoy all the bandwidth, no need to compete with other devices.
What are the functions of a vro of a wireless switch? What is the difference?
First, the HUB, that is, the HUB. Its function can be simply understood as connecting some machines to form a LAN. A vswitch, also known as a switch-type hub, works basi
running the service. Each member checks the information to keep other members updated. In a group with only two members, each member periodically writes a timestamp and cluster status information to the two shared cluster partitions in the shared disk storage area. To ensure proper cluster operations, if a member cannot write data to the primary shared cluster partition or block shared cluster partition at startup, it will not be allowed to join the cluster. In addition, if a cluster member fai
