Here are some effective methods I summarized:
Method 1: delete node_ Module, and then install (NPMI);
method 2: delete node_ Modules, run NPM cache clean or NPM cache clean — force command, and then install;
method 3: upgrade the node version and delete the node_ Modules, and then install it.
When using redis cli to connect the redis cluster for data operation, an error is reported
./redis-cli -h 192.24.54.1 -p 6379 -a '123456'

This situation is generally caused by not setting the cluster mode when starting redis cli .
When starting, use the - C parameter to start the cluster mode. The command is as follows:
./redis-cli -h 192.24.54.1 -p 6379 -a '123456' -c
192.24.54.1:6379> get name

Error 2002 (HY000): can’t connect to local MySQL server through socket ‘/ var/run/mysqld/ mysqld.sock ’ (2)
When starting mysql, it appears:
because I haven’t used MySQL under Ubuntu for a long time, I thought my password was wrong, and I repeatedly lost it several times. I found that it’s still like this. I also checked the related blogs on the Internet and found that it can’t work. Generally, this kind of error appears on the Internet, which is a bit similar to
In fact, it’s not the same. Pay attention to distinguish the following folders, so go to the configuration file of Mysql to see where the socket folder is, and the configuration file of MySQL is in
/etc/MySQL/ my.cnf In this, cat has a look:
found this sentence remember to edit So when you install mysql, the MySQL Server package is not installed (I don’t know how to get in before, ha ha), so you can install this package
you can also check whether there is this package first
so after installing mysql-server-5.7, you can enter the root password.

now my.cnf There is no previous sentence
When installing, I read the tutorial and said that after activation, I need to crack the dynamic library file under the “crack” folder“ libmwservices.dll ”Replace it with “r2015b/bin/win64” under the installation directory of MATLAB 2015b\ libmwservices.dll ”
But I don’t have it in my crack file libmwservices.dll File… It’s strange that I downloaded the crack file again, but it’s still the same… Maybe it’s a version problem
or not
Finally, a practical method is found in another blog https://blog.csdn.net/m0_ 37638031/article/details/78982498
This blog contains not only the installation package of MATLAB, but also detailed and practical tutorials, especially the last step after activation
The specific steps are as follows:
After activation, copy the netapi32.dll file under the crack file (path as follows: MATLAB r2017b win64 crack/r2017b/bin/win64/netapi32.dll) directly to the installed matlab file (path as follows: C:// program files/Matlab/r2017b/bin/win64).
And then it’s working.

1： Preface
Recently, the domain name was upgraded. Because the test server is an intranet, the built test domain name cannot be resolved. The hosts file of the mobile phone needs to be modified. An error occurred when using the ADB command to obtain the root permission. Take this as a record.
Equipment: Xiaomi 4C
MIUI is: miui10 development version
The BL lock has been unlocked and the root permission has been obtained, but it is found that the hosts file can not be modified, and the system file lock needs to be unlocked. Therefore, the ADB command is used to unlock the system file lock. It is found that the device cannot be found due to the error. Two solutions are found, which can be tried by the blogger himself. The second solution is used by the blogger.
2： Solutions
The first one is the first one
1. First check who is occupying the port of 5037?Netstat – AON | findstr 5037
2. Kill the process that occupies the port.
3. If you start over, it will work well. However, bloggers are an exception, and still haven’t found the device list…
ADB devices — View devices
Second:
ADB reboot EDL or ADB reboot is OK. After the device is rebooted, it will work again.
3： Conclusion
If you also have this problem, you can try this method. I hope it can help you. If you are also a Xiaomi device and want to unlock or get the highest root permission, you can send a private message to me. I want a tutorial or tool.
I wish you success in your work!

Because the. Git directory of the project has the permission of root,
The solution is to switch to the root super administrator and modify the user of the file as the current computer user

Pymysql connect to MySQL reported an error of keyerror255. Recently, I was trapped for more than two months by a difficult problem. If you search this title, you can see that the search engine has provided n ^ 2 articles on solutions. Why do you still trap me for so long?Don’t I know Baidu?NO NO NO！！ The biggest problem is that my executive computer and data storage computer are not the same computer!!
Error information
File "D:\Programfiles\Anaconda3\lib\site-packages\pymysql\connections.py", line 1269, in _get_server_information
self.server_charset = charset_by_id(lang).name
File "D:\Programfiles\Anaconda3\lib\site-packages\pymysql\charset.py", line 38, in by_id
return self._by_id[id]
KeyError: 255
The main reason is that MySQL 8.0 updates many character sets, but these character sets are longer than 255 , so the old version of pymysql does not support characters longer than 255
Online can find a lot of articles to solve this problem, consistent solution, update pymysql
pip install --upgrade pymysql
The following casually put a, interested can see, don't look also doesn't matter, full text summary on a sentence update pymysql, directly execute the above update code, if solve, OK! All is well, you can quit, but you can't solve it. The link article is not meaningful. Let's continue to read my text
Django appears after changing the default database SQLite3 to pymsql Keyerror:255 How to upgrade pymysql
Solution
As mentioned before, my executive computer and data storage computer are not the same computer!!
My own computer is mysql5.7, and the data storage computer version is 8.1
because at the beginning, the company's network security was upgraded to a secondary level, and then the company's intranet VPN was updated once (big exchange, the interface is different),
so at the beginning, I thought it was caused by the network security policy,
after all, all the online updates are pymysql, I'm already up-to-date and can't update any more
In fact, the solution is in a word, too lazy to beat around the bush so many words
uninstall and reload MySQL
yes! You're right! Is the MySQL database to unload, and then re install a version of 8.0 and above
So the main reason is that at the beginning MySQL 8.0 has updated many character sets, but the length of these character sets exceeds 255
