The method of deploying Server with Python Automation script

This article focuses on "Python automation script deployment server method", interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Next let the editor to take you to learn "Python automation script deployment server method" it!

1. Preface

If the daily Python automation program runs stably locally, you can consider deploying it to the server and completely liberate your hands with scheduled tasks.

However, because automated programs are associated with platform compatibility, there are some dependent libraries that need special handling when running on the server.

two。 Operation steps

Take CentOS server as an example

2-1 install desktop environment

PS: if it is already installed, you can skip to the next step

We need to install a desktop environment "take GNOME as an example", set it to start in graphical mode, and open the graphical interface.

# install GNOME Desktop Environment yum groupinstall-y "GNOME Desktop" # set to launch systemctl set-default graphical.target in graphical mode # Open graphical interface startx2-2 install and configure remote Desktop

Take the most common VNC as an example

First, install VNC Server on the server and set the login password

# install vnc server yum install tigervnc-server-y # set login password for vnc viewer login password vncpasswd

Then, start VNC Server and open the corresponding port number

# enable VNC service systemctl start vncserver@:1 # set boot systemctl enable vncserver@:1 # View VNC service port netstat-lnpt | grep Xvnc # enable port number firewall-cmd-- add-port=5901/tcp-- permanent firewall-cmd-- reload

Finally, download VNC Viewer and remotely connect to the server using "IP address + port number + login password"

Download address:

Https://www.realvnc.com/en/connect/download/viewer/

PS:VNC Server explicitly specifies the IP address + port number

2-3 install Chrome browser

The browser installed by default on the server is FireFox,Chrome browser. You need to install it manually.

# download the latest Chrome browser wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm # install browser yum install google-chrome-stable_current_x86_64.rpm # check the version of Chrome browser google-chrome- version

After the installation is completed, it is found that using the Root user to launch the Chrome browser failed PS: the server Chrome browser does not support direct use. You need to start it with-- no-sandbox parameter.

# launch the Chrome browser in-- no-sandbox mode # method 1: command line launch / usr/bin/google-chrome-stable-- no-sandbox # method 2: modify the startup method of the Chrome browser shortcut icon # startup method:-- no-sandbox2-4 configure Chrome Driver and authorization

Download the corresponding version of Chrome Driver of the Chrome browser on the official website.

Download address:

Http://chromedriver.storage.googleapis.com/index.html

After decompressing, upload it to the server's "usr/bin" directory.

Finally, grant executable permissions to the chromedriver file

[root@localhost xh] # cd / usr/bin # Grant executable permissions [root@localhost bin] # sudo chmod + x chromedriver2-5 Visualized run Test

Upload the automation script to the server and set it to run in header mode

Note: since the Chrome of the server needs to be configured to start in no-sandbox mode, the automation script needs to add setting properties

Option = webdriver.ChromeOptions () # run in headless mode # option.add_argument ('headless') option.add_argument (' no-sandbox') option.add_argument ('disable-dev-shm-usage') option.add_experimental_option (' useAutomationExtension', False) option.add_experimental_option ('excludeSwitches', [' enable-automation']) browser = webdriver.Chrome (chrome_options=option)

After the headless mode test runs properly, you can turn on headless mode, write scheduled tasks, and associate automation scripts with scheduled tasks.

3. Last

In this paper, the step flow of deploying server with Selenium automation script is described.

It should be pointed out that visual debugging testing on the server is really necessary, which can help us to locate compatibility issues in advance.
