[Solved] xdd-plus-fetch qrcode error: Packet timed out,2-error: unknown flag

On xdd-plus-21-12-08, two errors were reported in running XDD. Jiqiren also hung up, no messages were sent, and the service stopped itself.
the following two errors were reported
fetch QRcode error: packet timed out,
2-error: unknown flag

With the help of some Qun friends, the tutorial is summarized as follows

dowload Time is slow, wait patiently. . . .

wget https://github.com/764763903a/xdd-plus/archive/refs/tags/v1.7.tar.gz

This file only needs to change which line of uin, that is, which line of QQ account, and replace it with your own (robot) QQ

[root@VM-4-10-centos qbot]# cat config.yml

chmod +x  xdd-linux-amd64

cd conf/
cp demo_app.conf app.conf
Here, copy the configuration file of the old version of conf.yaml to the conf/ directory of the new version, and it is not too troublesome to reconfigure
cp ~/xdd-plus/conf/config.yaml. # There is a dot at the end
cd /root/xdd-plus-1.7/
./xdd-linux-amd64
Then scan the QR code to log in to jiqiren's QQ.
Ctrl + c
nohup ./xdd-linux-amd64 &
(shang above Ctrl +c may need to log in again after exiting, here cat nohup.out, and then scan the code again, this is the log output file)

vim conf/config Yaml
change this in the slow query configuration
later: 1 # delay to prevent Black IP. Set the default 60 to 1. The unit is seconds

Then log in to QQ and leave a message if you have other questions

[Solved] Linux executes SQL script Error: Syntax error

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

/usr/bin/ssh-copy-id: ERROR: No identities found [How to Solve]

Look at the problem first

ssh-keygen -t rsa
ssh-copy-id localhost
/usr/bin/ssh-copy-id: ERROR: No identities found

The RSA and rsa.pub files are generated normally, but the SSH copy ID cannot be reported:/usr/bin/SSH copy ID: error: no identities found

After a closer look, the file size is 0

[hadoop@hadoop102 .ssh]$ ll

-rw-------. 1 hadoop hadoop 0 11月 21 21:34 id_rsa
-rw-r--r--. 1 hadoop hadoop 0 11月 21 21:34 id_rsa.pub

Look at the virtual machine disk. It has been used up

[Solved] allure Error: unrecognized arguments: — alluredir — clean alluredir

An integrated environment has been built locally and runs smoothly. When moving to the ECS for construction, allure always reports an error and prompts that the command is wrong. After repeatedly comparing various modules and versions of python, it is found that they are the same and always report this error

ubuntu@VM-16-9-ubuntu:/var/lib/jenkins/workspace/autotest_daily/pytestdemo$ sudo python3 all.py 
ERROR: usage: all.py [options] [file_or_dir] [file_or_dir] [...]
all.py: error: unrecognized arguments: --alluredir --clean-alluredir
  inifile: /var/lib/jenkins/workspace/autotest_daily/pytestdemo/pytest.ini
  rootdir: /var/lib/jenkins/workspace/autotest_daily/pytestdemo

I searched everywhere but couldn’t find it. I thought there was a problem with the version of allure pytest. Compared with the version number, the version number is the same, because the difference between the two servers lies in the difference of source addresses. Is there any difference in the same version? Stuck here for an hour, execute   Sudo PIP3 install — upgrade allure pytest

Installing collected packages: six, allure-python-commons, allure-pytest
Successfully installed allure-pytest-2.9.45 allure-python-commons-2.9.45 six-1.16.0

The problem is that the version of six is different. Finally, we found a different version. The version of six used for local construction is 1.14.0 and the server is 1.16.0

Attempt to downgrade the version of six

sudo pip3 install six==1.14.0

Then continue to build. When pytest is executed normally, the build is OK. I have to say that there are so many holes in Python.

The question is, what does six do?

I searched it again. This thing is used to be compatible with Python 2 and 3 modules. It can be seen from this,

allure   allure-pytest                     2.9.45
allure-python-commons             2.9.45

The first two modules are incompatible with six 1.16.0, so they bring this kind of pit.

[Solved] S3fs mount error: s3fs: unable to access MOUNTPOINT…

s3fs mount reports an error, prompting: s3fs: unable to access MOUNTPOINT /backup/fileserver/: Transport endpoint is not connected

s3fs appfiles.v1 /backup/fileserver/ -o passwd_file=/etc/passwd-s3fs -o url=http://192.168.12.30 -o uid=1002,gid=1002 -o use_path_request_style
Error Messages:
s3fs: unable to access MOUNTPOINT /backup/fileserver/: Transport endpoint is not connected

How to Solve this error:
1, confirm whether the network link ok.
ping 192.168.12.30
can ping through.
2, whether the port is open
telnet 192.168.12.30 80
port can be passed, that is not a network problem caused.
3, ls /backup/fileserver/
error message: ls: cannot access fileserver: Transport endpoint is not connected
It is good that there is an error, because ls will not report an error for an empty directory, but this error means that the directory is still mounted, but the link is not available.
Checking the process, the process hangs. I suspect that the process is hung, but the directory is not unmounted.
4. Manually unmount
umount /backup/fileserver/
No error is reported, good, that means the inference is correct.
5, mount test
s3fs appfiles.v1 /backup/fileserver/ -o passwd_file=/etc/passwd-s3fs -o url=http://192.168.12.30 -o uid=1002,gid=1002 -o use_path_request_ style
No error was reported, ok! The troubleshooting process is over. This means that the problem is caused by the lack of unmounting.
6, confirm whether it is mounted up:

df -hT
Filesystem Type Size Used Avail Use% Mounted on
devtmpfs devtmpfs 7.8G 0 7.8G 0% /dev
tmpfs tmpfs 7.8G 0 7.8G 0% /dev/shm
tmpfs tmpfs 7.8G 819M 7.0G 11% /run
tmpfs tmpfs 7.8G 0 7.8G 0% /sys/fs/cgroup
/dev/vda1 xfs 15G 4.8G 11G 32% /
/dev/vdb xfs 100G 4.0G 97G 4% /backup
tmpfs tmpfs 1.6G 0 1.6G 0% /run/user/0
s3fs fuse.s3fs 16E 0 16E 0% /backup/recordfiles
tmpfs tmpfs 1.6G 0 1.6G 0% /run/user/1000
s3fs fuse.s3fs 16E 0 16E 0% /backup/fileserver

Check that it is already there. Mount ok The whole process is over.
