BlaB! WS How to install (quick-and-easy) - CentOS + Apache

Requirements: A CentOS 7+ server/VPS with Apache, PHP5/PHP7 and MySQL/MariaDB. Access to that server via SSH as a root user. PHP shell_exec enabled in php.ini.

With SELinux in enforcing mode set globally (default on CentOS) you need Apache running in permissive mode which many experts consider a vulnerability. To enable SELinux permissive mode (Apache only) run:

yum install policycoreutils-python
semanage permissive -a httpd_t

Step 1

Download blabws-server 32-bit or 64-bit, unzip and upload the folder blabws-server under your /opt directory so that the path to the blabws-server executable file is: /opt/blabws-server/blabws-server

Step 2

You need an Apache module called proxy_wstunnel. You can enable proxy_wstunnel from a frontend such as cPanel, or:

Open /etc/httpd/conf.modules.d/00-proxy.conf and look for:

LoadModule proxy_wstunnel_module modules/

If not found, add the line at the end of the file and save.

Add to the config file of Apache (/etc/httpd/conf/httpd.conf) outside VirtualHosts:

ProxyPass "/MyWsServer/" "ws://localhost:9001/"

Save, restart Apache: systemctl restart httpd

Step 3

Download BlaB! WS (client), unzip the content in an empty folder and upload it to your server under your website root directory (most probably: /var/www/html). CHMOD blabws/config.php to 666, navigate with your browser to YOUR-URL.COM/blabws/index.php and follow the instructions (3 steps only).

Step 4

At the end of the installation process (Step 3) you'll see a link to the Admin CP - start your blabws-server from SERVER STATUS, press the ESC key to display the menu, go to Server, and set:

Save with OKAY, press the ESC key to display the menu, hit EXIT to go to chat. Done!
