vi /etc/php.ini
upload_max_filesize = 128M
Edit the main Apache configuration file (/etc/httpd/conf/httpd.conf) and change user and group from ‘apache’ to ‘asterisk’. Also, change ‘AllowOverride None’ directive to ‘AllowOverride All’.
Restart the Apache web server for the changes to take effect:
systemctl restart httpd.service
10. Configure MariaDB
Log in to the MariaDB server using the ‘root’ user login credentials and create new user and two databases:
mysql -u root -p
MariaDB [(none)]> CREATE DATABASE asterisk;
MariaDB [(none)]> CREATE DATABASE asteriskcdrdb;
MariaDB [(none)]> CREATE USER 'asterisk'@'localhost' IDENTIFIED BY 'Y0uR-PASSW0RD';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON asterisk.* TO 'asterisk'@'localhost';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON asteriskcdrdb.* TO 'asterisk'@'localhost';
MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> quit;
Do not forget to replace ‘Y0uR-PASSW0RD’ with a strong password.

Our tutorial is tested and working without a problem. Have you made sure that you’ve followed the instructions correctly?
Please try doing all of the described steps again and be more careful.
I do not see anything about installing httpd or MariaDB as requirement, but is does pop up in the configuration instructions later on. Is this an oversight, or do you asume a certain level of installed apllications on the host?
Great article. Thank you

You should edit the configuration files in the
/etc/asteriskdirectory and then restart Asterisk for the changes to take effect.Before installing SRTP, we must replace “nano /opt/srtp/test/rtpw_test.sh” RTPW=rtpw by RTPW=./rtpw
there’s no file under /var/run called asterisk ???

Hi Robert,
Installing Apache and MariaDB on CentOS 7 is explained in one of our previous blog posts.
Hi! I’m stuck at Step 8 in “make” since it says “collect2: error: ld terminated with signal 11 [Segmentation fault], core dumped”.
I am currently using the latest Linux kernel.
