Download Fusionpbx

There are fixes and enhancements in our fork so that it will install properly on MySQL.  The developer appears to have addressed them now, so if you want the latest updates you can install from https://github.com/fusionpbx/fusionpbx

Make sure the "." is included at the end of the git clone command.  That tells git to clone into the current directory instead of creating a /fusionpbx subdirectory.

cd /var/www/html
git clone -b 4.2 https://github.com/powerpbx/fusionpbx.git .

Copy conf Directory

mv /etc/freeswitch /etc/freeswitch.orig
mkdir /etc/freeswitch
cp -R /var/www/html/resources/templates/conf/* /etc/freeswitch

Apache config

# Add user freeswitch to group apache to avoid problems with /var/lib/php/sessions directory 
usermod -a -G apache freeswitch

# Set http server to run as same user/group as Freeswitch
sed -i "s/User apache/User freeswitch/" /etc/httpd/conf/httpd.conf
sed -i "s/Group apache/Group daemon/" /etc/httpd/conf/httpd.conf

# Set webserver to obey any .htaccess files in /var/www/html and subdirs 
sed -i ':a;N;$!ba;s/AllowOverride None/AllowOverride All/2' /etc/httpd/conf/httpd.conf

Set ownership and permissions

# Ownership
chown -R freeswitch.daemon /etc/freeswitch /var/lib/freeswitch \
/var/log/freeswitch /usr/share/freeswitch /var/www/html

# Directory permissions to 770 (u=rwx,g=rwx,o='')
find /etc/freeswitch -type d -exec chmod 770 {} \;
find /var/lib/freeswitch -type d -exec chmod 770 {} \;
find /var/log/freeswitch -type d -exec chmod 770 {} \;
find /usr/share/freeswitch -type d -exec chmod 770 {} \;
find /var/www/html -type d -exec chmod 770 {} \;

# File permissions to 664 (u=rw,g=rw,o=r)
find /etc/freeswitch -type f -exec chmod 664 {} \;
find /var/lib/freeswitch -type f -exec chmod 664 {} \;
find /var/log/freeswitch -type f -exec chmod 664 {} \;
find /usr/share/freeswitch -type f -exec chmod 664 {} \;
find /var/www/html -type f -exec chmod 664 {} \;

Systemd config

nano /etc/systemd/system/freeswitch.service

[Unit]
Description=FreeSWITCH
Wants=network-online.target

After=mariadb.service httpd.service

Create the $FREESWITCH_PARAMS file for extra parameters.  If freeswitch was installed from RPM this will probably already exist.

nano /etc/sysconfig/freeswitch

## Type:                string
## Default:             ""
## Config:              ""
## ServiceRestart:      freeswitch
#
# if not empty: parameters for freeswitch
#
FREESWITCH_PARAMS=""

Enable services

systemctl daemon-reload
systemctl enable mariadb
systemctl enable httpd
systemctl enable freeswitch
systemctl enable memcached
systemctl restart freeswitch

Fix fs_cli

If fs_cli command does not work with freeswitch running change the following config line. 

nano /etc/freeswitch/autoload_configs/event_socket.conf.xml

<param name="listen-ip" value="127.0.0.1"/>

systemctl restart freeswitch

Reboot and browse to the public IP address of the server

 http://xx.xx.xx.xx 

to complete the install using the following:

Username: superadmin (or whatever you want)
Password: somepassword (use whatever you want)

Database Name: fusionpbx
Database Username: fusionpbx
Database Password: somepassword
Create Database Options: check "Create the database"
Create Database Username: root
Create Database Password : (leave blank unless you have already added a root password)

Post install tasks are mandatory.

Post Install

Lock down the database server

mysql_secure_installation
systemctl restart mariadb

Answer Y to everything.

Enable freeswitch database connection

This sets Freeswitch to use mysql instead of sqlite.

nano /etc/freeswitch/autoload_configs/switch.conf.xml

<param name="core-db-dsn" value="freeswitch:fusionpbx:somepassword" /> 

systemctl restart freeswitch

Change Voicemail to Email app configuration

nano +119 /etc/freeswitch/autoload_configs/switch.conf.xml

<param name="mailer-app" value="/usr/bin/php /var/www/html/secure/v_mailto.php"/>
                <param name="mailer-app-args" value="-t"/>

systemctl restart freeswitch
