implement
curl harbor.od.comThe following error occurred
curl: (6) Could not resolve host: harbor.od.com; Unknown error
The reason is that there is an error in DNS
Open DNS profile
vim /etc/resolv.confFind the following. It is found that the DNS is inconsistent with your own configuration.
Modify the content behind the nameserver
Run again and you’ll succeed
Use the yum command prompt “except keyboardinterrupt, e: syntax error: invalid syntax”
Troubleshooting of error reporting using Yum command
Error reporting using Yum command
File "/usr/bin/yum", line 30
except KeyboardInterrupt, e:
^
SyntaxError: invalid syntax
Reason for the problem:
Yum package management uses python2 X, python2 X to Python 3.0 After X, problems occurred due to Python version syntax compatibility
Solution:
Modify the yum configuration file to point the python version to the previous version
vi /usr/bin/yum
#!/usr/bin/python2.7
Modify the urlgrabber ext down file and change the python version
vi /usr/libexec/urlgrabber-ext-down
#!/usr/bin/python2.7
An error was reported when downloading the code to the server today error: RPC failed; result=28, HTTP code = 0
Ending method: replace HTTPS with git or git + SSH.
As for the principle, there is no reason
When pushing the code to the code cloud, an error is reported.
The reason for the error is that there are no files in the directory, and an empty directory cannot be submitted
You can add a file

Demand scenario:
when deploying the production environment, you need to run the SQL script uploaded locally
Problem Description:
the local script runs normally, and liunux reports syntax error </ font>
syntax error
Cause analysis:
when running stored procedures or a long string of SQL scripts in Linux, you need to add fixed syntax at the beginning and end
beginning: \set sqlterm/
end:/\ set sqlterm
Solution:
add fixed statements \set sqlterm/and
/\ set sqlterm

Question 1 recurrence
System: Ubuntu 18.04 docker version: 20.10.7
when I start a container, run the following command:
docker run -itd \
--runtime=nvidia --gpus=all \
-e NVIDIA_DRIVER_CAPABILITIES=compute,utility,video,graphics \
image_name
report errors:
docker: Error response from daemon: Unknown runtime specified nvidia.
See 'docker run --help'.
Solution 1
This is because the user did not join the docker group and added his own user to the docker user group.
sudo usermod -a -G docker $USER
Question 2 recurrence
docker: Error response from daemon: Unknown runtime specified nvidia.
See 'docker run --help'.
Solution 2
NVIDIA docker2 needs to be installed
sudo apt-get install -y nvidia-docker2
Restart docker
sudo systemctl daemon-reload
sudo systemctl restart docker
Background: the customer reported that the Windows Server reported an error during automatic update and could not update

Troubleshooting steps:
1. Access the URL on the client according to the log http://xxxx.xxxx.xxx.xxx:8530/ClientWebService/client.asmx
The following occurs:
You can see the specific reason why the client cannot troubleshoot
2. Use the server to directly access the URL http://xxxx.xxxx.xxx.xxx:8530/ClientWebService/client.asmx
There is an error 
in which the type cannot be converted
Because I have contacted the code before and thought that some program files of WSUS had problems, I tried to copy files from other WSUS servers for backup and replacement, but it didn’t work
3. Search problem, and finally compare the hosting mode of WSUS service application resource pool in IIS server from “classic” to “integration”
4. When the client accesses the URL again, the following page appears and returns to normal
1. Error reporting
2. Solutions
Use the following command and reconnect
