Chorme/Chromium browser runs it’s on 9515 port and laravel dusk tries to connect to it through the Browser binary, but failing to do so. To resolve the case, we first, need to check if chromedriver for linux can run or not.
First, browse your laravel root directory, in my case, it’s the blog directory and then run the chromedriver for linux as following:
cd blog vendor/laravel/dusk/bin/chromedriver-linux
This should return something like the following if the driver able to load in memory:
[elastic-keldysh@pl1 blog]$ vendor/laravel/dusk/bin/chromedriver-linux
Starting ChromeDriver 85.0.4183.87 (cd6713ebf92fa1cacc0f1a598df280093af0c5d7-refs/branch-heads/4183@{#1689}) on port 9515
Only local connections are allowed.
Please see https://chromedriver.chromium.org/security-considerations for suggestions on keeping ChromeDriver safe.
ChromeDriver was started successfully.
But if it can not be loaded, it will return some kind of error like the following:
[elastic-keldysh@pl1 blog]$ vendor/laravel/dusk/bin/chromedriver-linux vendor/laravel/dusk/bin/chromedriver-linux: error while loading shared libraries: libX11-xcb.so.1: cannot open shared object file: No such file or directory
As the error suggests, it is failing to access the library called libX11-xcb. To install it in CentOS, you may run the following from root shell:
[root@pl1 lib64]# yum install libX11-xcb*
Once you see the following:
Installed: libX11-xcb-1.6.8-3.el8.x86_64 Complete!
You may now, go back to the user shell, and run the chromedriver-linux again:
[root@pl1 lib64]# su - elastic-keldysh

[elastic-keldysh@pl1 ~]$ cd blog

Only local connections are allowed.
Please see https://chromedriver.chromium.org/security-considerations for suggestions on keeping ChromeDriver safe.
ChromeDriver was started successfully.
Now, you may run the following to start using the laravel dusk:
php artisan dusk
After you are done resolving the 9515 error, you might also have to face another error with Chrome Binary, have a look at the following on how to resolve the error:
