Today, I tried to run wsa (Windows subsystem for Android) with win11. I found that I had to turn on Hyper-V to run. Then I found that the virtual machine VMware could not run. So I turned off Hyper-V and finally opened the virtual machine, but the network could not be connected (NAT mode is OK, but bridge mode is not)
after searching on the Internet, I changed this and that, Still No.
I fumbled and succeeded.
here is my solution:
No, as long as you have opened Hyper-V, there will be more of these two below. The default is automatic. It will give priority to these two, so we need to cancel these two checks
OK, and then enter the Ubuntu virtual machine, It is found that the network has returned to normal.
it took an afternoon to solve it. I hope I can help my friends in the future

View standard’s log
The log contains a large string of simulator information, so directly search the x86 keyword, and then check which framework is included, and then CD go in. Remember to enter the framework and remove i386 and x86_ 64。
lipo -info xxxx
Remove command:
lipo -remove i386 xxxx -o xxxx
lipo -remove x86_64 xxxx -o xxxx
View errors
Before, I was misled by the Internet. I had to search all the "x86" keywords, and then search out Ruby (universal. X86_64) , thinking about viewing or updating with lipo , which wasted a lot of time and failed… Finally, homebrew
is also updated
Finally, I tried to search error , and found that framework was included in bundle of tent , and finally it was OK to remove it
IPA processing failed will be prompted when IOS ad hoc , the framework in tencetopen is attached with x86 , after removal, you can check the keywords of failed or error in your log.

zookeeper_ An error is reported when the exporter starts
Problem Description: two machines, one zookeeper_ Data can be found when the exporter is started normally, and the other one can be started normally, and then no data can be detected.
note: check through Prometheus ZK_ The exporter is alive, but the data of the machine reporting an error cannot be found
Error log: erro [0014] unable to open connection to zookeeper error = “dial TCP: lookup localhost on 8.8.8.8:53: no such host”
resolvent:
It’s a DNS problem, so check the/etc/resolv.conf file of the machine that reports an error and compare it with the file of the machine that does not report an error. If it is found that there is an inconsistency, change it to the constant one, and then solve the problem
Log in to Prometheus to view ZK_ Up data
Then the problem is solved

Solve the java.net.connectexception: connection rejected: connect error

fetch-registry: falseWhen a system is deployed on weblogic12.2.1.3, it reports an error “IllegalStateException zip file closed”. When it is deployed on weblogic12.2.1.2, it does not report an error and can be accessed normally.
Problem phenomenon
When a system is deployed on weblogic12.2.1.3, it reports an error “IllegalStateException zip file closed”. When it is deployed on weblogic12.2.1.2, it does not report an error and can be accessed normally.
Problem analysis
You can find the clear reason on the official website through the error report. The main reason is a bug in Weblogic. Because the application jar file is closed silently due to inactivity, because the jarfile class implements the autoclosable interface, and jarurlhandler does not handle this exception at present, this error is reported. Therefore, it is repaired through patch 27774698. The repair principle is to add a catch block to handle exceptions, And reopen the jar file when there is an IllegalStateException.
In addition, the official suggestion is to apply this patch only when reporting this error. It is not necessary to apply this patch to every system.
Problem continuation
The above problems are solved by patching 27774698, and the deployment application reports an error error creating bean with name ‘wsrmsafregistrationservice’. After that, you can see that spring is initializing bean and wsrmsafregistrationservice in the log, but its full class name is com.oracle.webservices.impl.wls.wsrmsafregistrationservice, which is used internally, @ inject @ named (“safserverservice”), private SAFServerService safServerService; Therefore, when spring does autowire automatic link, it scans the classes inside Weblogic. This scanning should not occur. Therefore, spring autowire filter should be added to the code to avoid scanning the classes inside Weblogic. For the specific adding method, see the official website link doc ID 2397321.1.
Problem handling
The problem of “IllegalStateException zip file closed” is solved by patching 27774698. After the application code is changed and the spring autowire filter is added, the application is successfully deployed and can be accessed normally. This problem is solved!

The result is still
Internet search method:
Test port 443 can be successful
$ ssh -T -p 443 [email protected]
Referring to the online method, the solution is as follows:
Locate git’s config file /etc/ssh/ssh_ Config and edit

Invalid column reference when using round in hive
Group by must be added to the hive query SQL, otherwise the column col in the selection list is invalid because it is not included in the aggregate function or group by clause.
Generally speaking, count , round should be regarded as aggregate functions without group by
however, hive does not consider the use of round as an aggregate function. The fields used should be added to group by, and the fields used in round should be added to group by
otherwise, an error is reported invalid column reference

Solutions to errors in the final running of JDBC programming
An error is reported at the end of JDBC programming:
Exception in thread “main“ java.sql.SQLException: Unknown initial character set index ‘255‘ received
resolvent:
When establishing a connection between JDBC and the database, add the following after the URL:

An error occurs when pymysql uses% d to pass in parameters
Error:
When using pymysql, an error occurs when using% d to pass parameters in the SQL statement. As shown in the figure: 
Error information: typeerror:% d format: a number is required, not str
Cause of problem:
When a parameter of type int is passed in, it is converted to a parameter of type str. Therefore, the solution is to change% d into% s, pass in int type, and it can still be executed.
Modified: 
Data of type int passed in:
Can execute successfully
Solution:
When data of type int is passed in, the parameter is still passed with% s.
