[Solved] jumpserver nginx Error: Connect websocket server error

After installation, the jumpserver selects a custom port, and the HTTP port 80 is changed to 88. After forwarding through nginx, remember to set the upgrade of nginx, otherwise it will prompt: connect websocket server error

Nginx is configured as follows:

##Jump
server {
listen 80;
server_name jump.xxxxxx.cn;

location/{
proxy_pass   http://127.0.0.1:88;
        proxy_http_version      1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
}
}

This will not prompt an error

[Solved] Error: ER_ACCESS_DENIED_ERROR: Access denied for user ‘root’@‘localhost’ (using password: YES)

Add the port number when configuring the server file

// Create the connection of database
const mysql=require('mysql')
const db=mysql.createPool({
  host:'127.0.0.1',
  port:'3307',
  user:'root',

[Solved] Linux program error: dpkg is interrupted. You must manually run ‘sudo dpkg — configure – a’

The Linux program reports an error: dpkg is interrupted. You must manually run ‘sudo dpkg — configure – a’ to solve this problem.

Run the following command to resolve the error

sudo rm /var/lib/dpkg/updates/*
sudo apt-get update
sudo apt-get upgrade

The main reason should be that there are errors in the data in the/var/lib/dpkg/updates folder, resulting in errors in the software update program, so they have to be completely deleted. The sudo apt get update command will re-establish these data, use sudo apt get upgrade to update the details of the software installed in your computer, and update the software to the latest version according to the details of the software.

[Solved] Error running ‘TomEE 10.0.121‘: The selected directory is not a TomEE hom

Today, I watched the video of Lao Du’s servlet and tried to start the Tomcat server after typing the code. I found this: error running ‘tomee 10.0.121 ‘: the selected directory is not a tomee Hom error.

Then I didn’t look at the error carefully. Subconsciously, I thought my Tomcat path was wrong. I looked it up and found that there was no problem

Finally, take a closer look at the good guy Tomcat created to tomcatee. No wonder it can’t be started.

Solution:

Just change back to normal Tomcat

Finally, click the servlet according to the old Du code

[Solved] minio Failed to Upload File Error: The difference between the request time and the server‘s time is too large.

Problem Description:

Minio upload failed. The background controller reports an error. The error information is as follows:

The difference between the request time and the server's time is too large.

Cause analysis:

The system time zone is inconsistent with the hardware time zone

Solution:

Note: when uploading files, you need to adjust the time of Linux server to be consistent with that of windows!

Step 1: install NTP service

yum -y install ntp

Step 2: start the startup service

systemctl enable ntp

Step 3: start the service

systemctl start ntpq

Step 4: change the time zone

timedatectl set-timezone Asia/Shanghai

Step 5: enable NTP synchronization

timedatectl set-ntp yes

Step 6: synchronize time

ntpq -p

Finally, you can try to enter the command} on the console to check whether it is consistent with the windows system time

[Solved] jenkins-deleteDir Error (FilePath is missing)

Today’s development feedback has been using the good Jenkins compilation service, but it reported an error

Look at the log and say something is wrong with deletedir

org.jenkinsci.plugins.workflow.steps.MissingContextVariableException: Required context class hudson.FilePath is missing
Perhaps you forgot to surround the code with a step that provides this, such as: node

Then after development and adjustment

Start reporting another error

After developing no solution, he found me

I looked at the pipeline

pipeline {
    agent{ label 'qa-gpu016.test.cn' }
    parameters {
