[asterisk-users] Asterisk and CentOS 8

[Patrick Wakano]

Hello George,
Hope this finds you well!
I wonder if there has been any progress on this matter?

I've been working to have Asterisk running on CentOS 8 and our jump from
CentOS 6 to 8 doesn't look too bad.... The missing packages found are:
gmime-devel, iksemel-devel, corosynclib-devel, libresample-devel, hoard and
python-devel. Python-devel could be replaced by python2-devel or
python3-devel (python36-devel), but I am not sure if there is any python
incompatibility... gmime-devel, iksemel-devel and hoard seems of no use
(and they were already missing for CentOS 6 too), so only corosynclib (if
you are using it) and libresample may be a problem.... Does anyone knows
what is the use of libresample-devel package?

Just to share the experience so far, to build Asterisk it is needed to
install the epel-release and enable PowerTools. By ignoring the missing
packages, the compilation works and we can start Asterisk. My only concern
was about the libresample-devel because in the past I think its absence
caused issues when loading/starting pjsip modules, but it didn't happen
this time (but I am not using pjsip, I just loaded it with the sample
config files)....
Following on and making Asterisk a systemd service instead of using init.d,
I first checked the service file under contrib/systemd but it seems to
serve a different purpose, so it could not be used. Instead a very simple
one does the job. Just make sure your exec cmd does not have the '-c'
option (used in safe_asterisk), because this was causing me a 100% CPU
usage (related to this:
https://unix.stackexchange.com/questions/191621/systemd-service-using-100-of-my-cpu-when-it-doesnt-if-i-start-it-without-syste/368037#368037
)
Be aware that SELinux may cause permissions and access problems when
running as systemd service.... It took me a whole day to figure out that
under our configuration (that have included files outside the /etc/asterisk
folder) the "problem" was SELinux.
Finally, configure firewalld to allow the SIP and RTP ports and you should
be ready to go.
Also, we are using rpmbuild to create an Asterisk package. rpmbuild (or new
red hat policies) is more strict and now complains about the python
shebangs that do not have a version (files contrib/script/ref*.py -> what
is this used for??). When using the DONT_OPTMIZE flag the compiler warns
for every single file saying, so it is quite annoying but does not to cause
issues:
/usr/include/features.h:381:4: warning: #warning _FORTIFY_SOURCE requires
compiling with optimization (-O) [-Wcpp].
Anyway, these problems do not happen if you manually build with the simple
configure and make commands.

Cheers,
Patrick Wakano
