use yum install to install above dependencies should be fine. And be careful your are 64 bit or 32 bit.

2. Install VNC server:

and make sure you set your password through

vncpasswd

and know what to start/stop/kill vnc

systemctl start [email protected]:1.service
systemctl stop [email protected]:1.service

vncserver -kill :1

and your port should be 5901 (if you use 1.service)

3. use gnome-terminal:

export DISPLAY=:0
gnome-terminal --display=:0

4. in your js file, make sure your browser has below arguments:

const browser = await puppeteer.launch({args: ['--no-sandbox', '--disable-setuid-sandbox']});

Then your js file:

node index.js

6. If you need to use cronjob, you can try like this:

export DISPLAY=:0; node index.js

Just for my reference.

server {
    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;

    root /var/www/laravel/public;
    index index.php index.html index.htm;

    server_name localhost;

    location / {
            try_files $uri $uri/ =404;
    }
}

Problem: The folder permission all ready to set the appropriate one (744, etc). but still can not access some page, or some of the pages can not access due to permission denied.

Solution: use chcon -t httpd_sys_rw_content_t folder/ -R, replace folder/ with your folder

chcon -t httpd_sys_rw_content_t folder/ -R
