Open Source - How do I completely remove Asterisk and DAHDI installed from source?
Please note that the following process only for asterisk implementation that has been installed from source, If you have installed Asterisk or DAHDI using a Package manager (such as yum, apt-get, etc), please use the manager interface to remove it.
Stop all related services
[root@server ~]#[root@server ~]# killall -9 safe_asterisk
[root@server ~]# service asterisk stop
[root@server ~]# service dahdi stop
Confirm if Asterisk and Dahdi are no longer running with ps aux
[root@server ~]# ps aux | grep asterisk Note: ps aux should only return lines like these if the process was stopped successfully, example:
root@server:~# ps aux | grep asterisk
root 19616 0.0 0.0 4356 744 pts/0 S+ 22:12 0:00 grep asterisk\|dahdi
Confirm DAHDI Drivers are unloaded with lsmod:
[root@server ~]# lsmod | grep dahdi
Example:
[root@server ~]# lsmod | grep -i dahdi
dahdi_voicebus 49298 2 wctdm24xxp,wcte12xp
dahdi_transcode 5272 1 wctc4xxp
dahdi 209513 20 wcb4xxp,wcaxx,wctdm24xxp,wctdm,wcfxo,wcte13xp,wcte12xp,dahdi_voicebus,wcte11xp,wct1xxp,wcte43x,wct4xxp,oct612x,dahdi_transcode
crc_ccitt 1337 2 wctdm24xxp,dahdi
In the example above dahdi modules such wctc4xxp, wctdm24xxp, and wcte12xp are listed. for each of these modules we will need to run modprobe -r to remove them. Example: modprobe -r wctc4xxp
Remove asterisk and dahdi files
Note: The following commands will delete all the configuration files
[root@server ~]# rm -rf /etc/asterisk
[root@server ~]# rm -f /etc/dahdi.conf
[root@server ~]# rm -rf /var/log/asterisk
[root@server ~]# rm -rf /var/lib/asterisk
[root@server ~]# rm -rf /var/spool/asterisk
[root@server ~]# rm -rf /usr/lib/asterisk
Now your Asterisk system has been completely removed. To install DAHDI, libPRI and Asterisk reference the Asterisk wiki at https://wiki.asterisk.org/wiki/display/AST/Installing+Asterisk+From+Source
