Configuration

External Recordings Server allows to convert and store Recordings in external server thus increasing storage space on switch server (Asterisk). It will also reduce load on switch server because wav to mp3 convertion is executed in external server.


NOTE: Configuration applies for fresh CentOS 6 or CentOS 7 server.


Configuration in GUI and Asterisk servers

External Recordings Server can be configured in ADDONS -> Recordings -> Settings

Recordings external server.png

Check 'User external Server' checkbox, enter external server IP, SSH port and login username.

NOTE: make sure that servers are configured with SSH keys! Login by password will not work for External Recordings Server.
This must be done on each GUI and Asterisk server!!!

External recordings server must be accessible using both root (/root/.ssh/id_rsa) and special GUI /var/www/.ssh/id_rsa) SSH keys. Just execute script below and it will check SSH keys and connectivity and will print exact command you need to enter for correct configuration. Make sure that External Recordins Server details: (IP, Port, Login) are already entered as shown in sreenshot above before executing these commands: 

svn update /usr/src/mor

On Centos 6: 

/usr/src/mor/x16/maintenance/test_fix_scripts/various/check_external_recordings_server_access.sh

On Centos 7: 

/usr/src/mor/x16/maintenance/test_fix_scripts_c7/various/check_external_recordings_server_access.sh


In SETTINGS -> Billing -> Servers add new server, where

"Hostname for SIP" and "Server IP for SIP" are External Recordings Server IP,

"Type" is "Other",

"GUI" and "DB" are disables (red cross).

Configuration in Database server

In Database Server create MySQL user for External Recordings Server: 

 CREATE USER 'mor'@'IP_OF_RECORDINGS_SERVER' IDENTIFIED BY 'mor';
 GRANT ALL PRIVILEGES ON `mor`.* TO 'mor'@'IP_OF_RECORDINGS_SERVER' WITH GRANT OPTION ;


Configuration in External Recordings server

1. Install required packages and dowload sources: 

yum -y install subversion gcc wget perl-IO-Socket-SSL
svn co http://svn.kolmisoft.com/mor/install_script/trunk/ /usr/src/mor

2. Install Apache (change MOR version accordingly in the script): 

#Centos 6 only
/usr/src/mor/x16/gui/apache_install.sh
/usr/src/mor/x16/gui/apache_uid_fix.sh
iptables -F
/etc/init.d/iptables save

#Centos 7 only
/usr/src/mor/x16/gui/apache_install_c7.sh
/usr/src/mor/x16/gui/apache_uid_fix_c7.sh
/usr/src/mor/x16/gui/rvm_install_c7.sh
/usr/src/mor/x16/gui/ruby_install_c7.sh

3. Install MySQL (change MOR version accordingly in the script): 

#Centos 6 only
/usr/src/mor/x16/mysql/mysql_install.sh

#Centos 7 only
/usr/src/mor/x16/mysql/mysql_install_c7.sh

4. Create needed directories and permissions: 

mkdir -p /var/log/mor
chmod 755 -R /var/log/mor
mkdir -p /etc/mor/
mkdir -p /var/lib/asterisk/agi-bin/
mkdir -p /usr/local/mor/recordings/
chmod 777 -R /usr/local/mor/

5. Install scripts (change MOR version accordingly in the script): 

cd /usr/src/mor/x16/scripts/

gcc -Wall -Wunused -g -I/usr/include/mysql mor_record_remote.c -o mor_record_remote -lmysqlclient -lnsl -lm -lz -L/usr/lib/mysql -L/usr/lib64/mysql
cp -fr mor_record_remote /usr/local/mor

gcc -Wall -g -I/usr/include/mysql mor_record_control.c -o mor_record_control -lmysqlclient -lnsl -lm -lz -L/usr/lib/mysql -L/usr/lib64/mysql
cp -fr mor_record_control /usr/local/mor

gcc -g -Wall -o mor_delete_old_recordings mor_delete_old_recordings.c -L/usr/lib/mysql -L/usr/lib64/mysql -lmysqlclient -lm
cp -fr mor_delete_old_recordings /usr/local/mor/

gcc -Wall -g -o mor_server_loadstats mor_server_loadstats.c -L/usr/lib/mysql -L/usr/lib64/mysql -lmysqlclient -lpthread
cp -fr mor_server_loadstats /usr/local/mor/mor_server_loadstats
cp -fr mor_server_loadstats_service /etc/init.d/mor_server_loadstats
chmod +x /etc/init.d/mor_server_loadstats
chkconfig --add mor_server_loadstats
chkconfig --level 2345 mor_server_loadstats on

cp -fr cronjobs/mor_delete_old_recordings /etc/cron.d/

cp -fr sendEmail /usr/local/mor/

/usr/src/mor/x16/maintenance/logrotates_enable.sh
echo "0 0 * * * root /usr/sbin/logrotate /etc/logrotate.conf > /dev/null 2>&1" > /etc/cron.d/mor_logrotate
chmod 644 /etc/cron.d/mor_logrotate

service crond restart

6. Install Lame (change MOR version accordingly in the script): 

/usr/src/mor/x16/helpers/lame_install.sh

7. Symlink directories: 

ln -s /usr/local/mor/recordings /var/www/html/recordings

8. Create configuration files:

Create file: 

vi /etc/mor/system.conf

Enter: 

# database connection settings
dbhost = Database_server_IP
dbname = mor
dbuser = mor
dbsecret = mor
dbport = 3306

server_id = unique server ID; same as on GUI

Save file.

Create file: 

vi /var/lib/asterisk/agi-bin/mor.conf

Enter: 

host = Database_server_IP
db = mor
user = mor
secret = mor
port = 3306

Save file.

9. Edit /etc/httpd/conf/httpd.conf

Change from: 

<Directory />
    Options FollowSymLinks
    AllowOverride None
</Directory>

To: 

<Directory />
    Options FollowSymLinks
    AllowOverride All
</Directory>

And change from: 

# AllowOverride controls what directives may be placed in .htaccess files.
# It can be "All", "None", or any combination of the keywords:
#   Options FileInfo AuthConfig Limit
#
    AllowOverride None

To: 

    AllowOverride All

10. Run: 

chcon -R -h -t httpd_sys_content_t /var/www/html/recordings/
service httpd restart

11. Edit /etc/selinux/config

Change from: 

SELINUX=enforcing

To: 

SELINUX=disabled

12. Reboot server: 

reboot

13. Centos 7 firewall configuration: Checking which zone is active 

firewall-cmd --get-active-zones
public
 interfaces: eth0

Adding to the public zone IP and port 

firewall-cmd --zone=public --add-source=GUI_IP/32
firewall-cmd --zone=public --add-port=80/tcp

Checking if it works and save to permanent 

firewall-cmd --runtime-to-permanent

If iptables are used instead or firewalld: 

iptables -I INPUT -p icmp -j ACCEPT
iptables -A INPUT -p tcp -m tcp --dport 80 -m conntrack --ctstate NEW,ESTABLISHED -j ACCEPT
iptables -A INPUT -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT
iptables -A INPUT -s 11.11.11.11/32 -p tcp -j ACCEPT
iptables -A INPUT -s 11.11.11.11/32 -p udp -j ACCEPT
# repeat for each system server
iptables -A INPUT -j DROP

service iptables save

14. Optionally, if you want to relocate old local recordings to an external server, after moving files, you have to update records in "recordings" table to local=0.


Troubleshooting

If Recordings are not displayed in GUI check the following log files in both servers:

/var/log/mor/mor_record_file.log
/var/log/mor/record_file.log
