Re: [SR-Users] Kamailio in cloud environments

You can also update kamailio.cfg to include listeners.cfg Example. Need add to kamailio.cfg ####### Listeners ########## include_file "/var/run/kamailio/listeners-eth0.cfg" Before kamailio started you will generate listeners.cfg file. This may by done by drop-in file. Need create "/etc/systemd/system/kamailio.service.d/10-listners-eth0.conf" with content [Service] ExecStartPre=/bin/curl -s -S --output /var/run/kamailio/listeners-eth0.cfg http://169.254.169.254/latest/meta-data/public-ipv4 ExecStartPre=/bin/sed --in-place --regexp-extended -e 's/(.*)/listen=udp:\1:5060\nlisten=tcp:\1:5060\n/' /var/run/kamailio/listeners-eth0.cfg On Mon, Nov 11, 2019 at 2:50 AM David Villasmil < david.villasmil.work(a)gmail.com&gt; wrote: > That's the one, thanks @Karsten! > > > More info, i changed my systemd unit to execute a script when starting up, > like so: > > # cat /etc/systemd/system/multi-user.target.wants/kamailio.service > [Unit] > Description=Kamailio (OpenSER) - the Open Source SIP Server > After=network.target > > [Service] > Type=forking > Environment='CFGFILE=/etc/kamailio/kamailio.cfg' > Environment='SHM_MEMORY=64' > Environment='PKG_MEMORY=8' > Environment='USER=kamailio' > Environment='GROUP=kamailio' > EnvironmentFile=-/etc/default/kamailio > EnvironmentFile=-/etc/default/kamailio.d/* > # PIDFile requires a full absolute path > PIDFile=/var/run/kamailio/kamailio.pid > ExecStart=/etc/kamailio/startkam.sh > Restart=on-abort > > [Install] > WantedBy=multi-user.target > > And /etc/kamailio/startkam.sh is like: > > #!/bin/bash > > MYSQL=$(/etc/kamailio/aws-getpass.sh dev us-east-1 dburl) > SHM_MEMORY=64 > PKG_MEMORY=8 > USER=kamailio > GROUP=kamailio > CFGFILE=/etc/kamailio/kamailio.cfg > /usr/sbin/kamailio -P /var/run/kamailio/kamailio.pid -f $CFGFILE -m > $SHM_MEMORY -M $PKG_MEMORY -u $USER -g $GROUP -A "DBURL=\"$MYSQL\"" -A > "CBDBURL=\"cb=>$MYSQL\"" -A "ASGDBURL=\"asg=>$MYSQL\"" > > which in turn calls /etc/kamailio/aws-getpass.sh, which is the actual > script talking to AWS via BOTO3 to get the data i need. > > You can just change the params and use them in your kam script normally > like: > > modparam("acc", "db_url", DBURL ) > > Hope that helps. > > Regards, > > David Villasmil > email: david.villasmil.work(a)gmail.com > phone: +34669448337 > > > On Sun, Nov 10, 2019 at 9:22 PM Alex Balashov &lt;abalashov(a)evaristesys.com&gt; > wrote: > >> -A ... oh wow.
