Install cutycapt

Error reported when running cutycapt

Cutycapt: cannot connect to X server: 0
You also need to install Xvfb

Yum install Xvfb

After Xvfb is installed, cutycapt runs the command line.

Xvfb-run-server-args = "-screen 0, 1280 × 1200x24 & Prime; cutycapt-url = http://www.cnn.com -outstrap cnn.png

If multiple images are generated at the same time, run the Xvfb service on the backend.

Touch/etc/init. d/xvfb with content:

Registering in system and start:
Chmod + x/etc/init. d/xvfb
Chkconfig xvfb on
Service xvfb start

Now

Export DISPLAY =: 7 (actually you shoshould add this to your etc/bashrc)

For example, convert HTML to PNG using CutyCapt on a server without X

Although CutyCapt is a command line tool, it requires the X service to run. If you try to run on a machine without the X service, you will get the following error:

Cutycapt: cannot connect to X server: 0

If you want to run CutyCapt on a server that does not contain X, you can install Xvfb on the server (lightweight "fake" X11 service ). In this way, the CutyCapt will not report an error.

To install Xvfb on Debian, Ubuntu, or Linux Mint:

$ Sudo apt-get install xvfb

To install Xvfb on Fedora, CentOS, or RHEL:

$ Sudo yum install xvfb

After Xvfb is installed, run CutyCapt like this.

$ Xvfb-run -- server-args = "-screen 0, 1280x1200x24" cutycapt -- url = http://www.cnn.com --out1_cnn.png

It runs the Xbfb service first, and then uses CutyCapt to Capture webpages. Therefore, it may take a longer time. If you want to take multiple screenshots, you may need to start Xvfb as the background daemon in advance.
