Logstash error failed to execute action

The main reason why most of them report this error is that the conf file configuration is written incorrectly

How to Solve Chrome Error: net::ERR_FAILED

I found that I couldn’t access the local project as soon as I started up after the holiday.

At first I thought it was a back-end problem, but the back-end checked for a while and found no problem. Then I used the Google browser of three colleagues to test that my IP access project can be successful. Testing with other browsers was also successful…
I reinstalled chrome, but I still couldn’t. finally, I analyzed the network and found that the request was blocked
the solution is as follows:

    1. browser address bar input: chrome://flags/ Search: Secure origins treated as secure change enabled to disabled

    1. or paste the project address into the following input box, you don’t need to change it to disabled
    OK, successfully solved

fatal: unable to access 'https://github.com/asdf-vm/asdf-plugins.git/': gnutls_handshake() failed: The TLS connection was non-properly terminated.
plugin ruby not found in repository

After checking, you need to use libcurl4 OpenSSL dev to replace gnutls to compile GIT.

sudo apt-get install build-essential fakeroot dpkg-dev
mkdir ~/git-openssl
cd ~/git-openssl
sudo apt-get source git
sudo apt-get build-dep git

If there is an error that the source code cannot be found, use the command sudo vim /etc/apt/sources.list to open the file and uncomment the line with deb_src, save and run sudo apt update, and then execute the last command above.
Then:

sudo apt-get install libcurl4-openssl-dev
sudo dpkg-source -x git_2.17.1-1ubuntu0.9.dsc
cd git_2.17.1 # Actual version may differ

Then edit the Debian/control file and use the command sudo VIM deebian/control to change all libcurl4 gnutls dev to libcurl4 OpenSSL dev. (I only met one libcurl4 gnutls dev here)
then run the command:

# This step will take a long time, wait patiently
sudo dpkg-buildpackage -rfakeroot -b

sudo dpkg -i git_2.17.1-1ubuntu0.9_amd64.deb

That’s it. Just git again

I did it again in the afternoon. There was still the same problem. Finally, the reset agent solved it perfectly

[Solved] SpringMVC Error: element web-app must be declared

Problem background

Today, when learning spring MVC, you need to configure the web.xml file, and an error message element web app must be declared appears.

 

Solution:

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
                      http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"

[Solved] Errors encountered when using VS to write opengl code

Record the errors encountered when writing opengl code using vs:
problem:
error: the following is a new check for glut 3.0; Update your code.
after checking for a long time, it is found that this may be the reason why the portal
does not write the callback function of the window

Solution:
write the callback function yourself

glutDisplayFunc(&display);

Among them, display is the calling function written by yourself, for example:

glutDisplayFunc(DrawOval);//Draw callback function, glut mechanism, it will be executed when it feels the need to redraw

The drawOval here is the function I wrote to draw an ellipse

How to Solve Show() error caused by empty data

In order to solve the show() error caused by empty data, it is used during filtering! x. Isnullat (1) determines whether it is empty. If it is empty, it will be discarded

 

//Filter .getDouble(1) 1 refers to the first column, starting from 0
    
    DF.filter(x => !x.isNullAt(1) && x.getDouble(1) < 1995).show(10)

Jenkins uses NPM to build Vue error, and the manual build is normal

Error reporting scenario

Jenkins uses NPM to build Vue. The front end reports an error, and the manual build is normal

Error reporting, such as
