unnecessary. |
$ sudo dnf -y install setools setroubleshoot setroubleshoot-server |
$ sudo vim /etc/selinux/config |
You’re going to change the line SELINUX=enforcing to SELINUX=permissive. This |
will ensure the logfiles show potential SELinux errors, without actually blocking the |
relevant processes. |
Next, we’re going to give Asterisk ownership of the /etc/odbc.ini file. |
$ sudo chown asterisk:asterisk /etc/odbc.ini |
$ sudo semanage fcontext -a -t asterisk_etc_t /etc/odbc.ini |
Asterisk Installation |
| |
41 |
$ sudo restorecon -v /etc/odbc.ini |
$ sudo ls -Z /etc/odbc.ini |
If all is well, you should see now that the file context for this file has been set to aster |
isk_etc_t: |
-rw-r--r--. asterisk asterisk system_u:object_r:asterisk_etc_t:s0 /etc/odbc.ini |
There are a few more SELinux errors we’ve seen here during the writing of the book. |
They may have been corrected by the time you read this, but there should be no harm |
in running them: |
$ sudo /sbin/restorecon -vr /var/lib/asterisk/* |
$ sudo /sbin/restorecon -vr /etc/asterisk* |
Reboot the system, and we’re going to check the log for any nasty SELinux errors |
before we set it to enforcing. |
$ sudo grep -i sealert /var/log/messages |
There may be a few messages in there complaining about things Asterisk doesn’t need |
(for example, a hidden file named .odbc.ini), but so long as it’s not full of errors about |
all sorts of important Asterisk components, you should be good to go. One last thing |
you have to change is an SELinux Boolean to allow Asterisk to create a TTY. |
$ sudo setsebool -P daemons_use_tty 1 |
Edit the /etc/selinux/config file again, this time setting SELINUX=enforcing. Save and |
reboot once more. |
Verify that Asterisk is running (as user asterisk). |
$ ps -ef | grep asterisk |
asterisk 3992 3985 0 16:38 ? 00:00:01 /usr/sbin/asterisk -f -vvvg -c |
OK, we’re nearly done with the installation now. |
Firewall Tweaks |
We’ll make a couple of firewall tweaks to prepare our system for SIP (and SIP Secure). |
$ sudo firewall-cmd --zone=public --add-service=sip --permanent |
$ sudo firewall-cmd --zone=public --add-service=sips --permanent |
Final Tweaks |
Your Asterisk system is ready to roll. |
Let’s put some initial data into the configuration files, so that in the next chapter we |
can begin to work with our new Asterisk system. |

Chapter 3: Installing Asterisk |
Since we’re going to use the PJSIP channel for all of our calling, we’re going to tell |
Asterisk to look for PJSIP configuration in the database: |
$ sudo -u asterisk vim /etc/asterisk/sorcery.conf |
[res_pjsip] ; Realtime PJSIP configuration wizard |
; eventually more modules will use sorcery to connect to the |
; database, but currently only PJSIP uses this |
endpoint=realtime,ps_endpoints |
auth=realtime,ps_auths |
aor=realtime,ps_aors |
domain_alias=realtime,ps_domain_aliases |
contact=realtime,ps_contacts |
