Configuring apache for Web Socket SSL Switchboard

Unfortunately there is no available Server Websocket library supporting SSL out of the box. To allow Websocket connections over SSL, it is needed to configure a reverse proxy in Apache.

While CentOS 7 supports proxying websocket directly, unfortunately Apache shipped with CentOS 6 doesn't not support proxying Websocket protocol, so ad additional package needs to be installed. The package can be installed from the server repository:

yum -y install https://demo.mirtapbx.com/mirtapbx_support/mod_proxy_wstunnel-0.1-1.el6.fws.x86_64.rpm

Once this module is installed, you need to configure your reverse proxy by adding:

<IfModule mod_proxy.c>
    ProxyPass "/wsrtportal/" "ws://127.0.0.1:8081/" retry=0 timeout=5
    ProxyPassReverse "/wsrtportal/" "ws://127.0.0.1:8081/"
</IfModule>

If you prefer, you can just copy the wsproxy.conf file from MiRTA PBX protected folder in /etc/httpd/conf.d and restart your web server.

The port needs to match the port specified in the Admin/Settings "Real Time Portal service - Listening Port"

Don't forget to add to your /etc/rc.local and to start manually the first time

nohup /usr/local/bin/restartrtportal.sh &

Updating libraries

It can be needed to upgrade some libraries used by the software, in this case you need to first install composer

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('SHA384', 'composer-setup.php') === '544e09ee996cdf60ece3804abc52599c22b1f40f4323403c44d44fdfdd586475ca9813a858088ffbc1f233e9b180f061') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"

then run

php composer.phar update
