KAZOO Support Channels

This documentation is curated by 2600Hz as part of the KAZOO open source project. Join our community forums here for peer support. Only features in the docs.2600hz.com/supported space are included as part of our 2600Hz Support Services plan.

Installation Guide for CentOS 7#

This is a reference guide for installing all of the necessary components for Kazoo. Once you have completed this guide, you should have an all-in-one installation of Kazoo complete and ready to configure for use.

The CentOS packages for the various dependencies are installed along with a wrapper that sets up the various configs and scripts that Kazoo needs. So when you install `kazoo-kamailio` you get the vanilla Kamailio packages along with the `kazoo-kamailio` overlay. Be aware that you'll need to use `kazoo-kamailio` when interacting with systemd.

A living guide#

This guide is an attempt to make installing all the various components straightforward to get a working All-in-One Kazoo installation for testing purposes. However, packages are updated in the CentOS repos, new versions of Kazoo get released, and other things that can cause this guide to bitrot.

We need your help to keep this up to date by:

  1. Reporting on the forum about where in the guide things broke down, or that you didn't understand.
  2. Using the edit link to edit this document and issue a pull request.

Gain access to the FreeSWITCH repositories#

SignalWire Personal Access Tokens (PAT)s are required to access FreeSWITCH install packages. Follow the guide on FreeSWITCH's site to generate a token.

Setup the server#

This guide builds a server using the CentOS 7 Minimal ISO. Once you have that installed on a server (or virtual machine), it is time to setup the host. Some of the commands below are optional (and noted as such) - check whether you need to run them first.

Note

Please remember to replace '172.16.17.18' with your server's actual IP address (not localhost either), 'aio.kazoo.com' with your actual Host Name (FQDN) and TOKEN with your SignalWire token.

# pre-configure custom defaults:
export IP_ADDR=172.16.17.18
export _HOSTNAME=aio.kazoo.com
export TOKEN=SIGNALWIRE_TOKEN

# You can find the latest Release RPM here: https://packages.2600hz.com/centos/7/stable/2600hz-release/
# Currently, 4.3 is considered 'stable' so:
# https://packages.2600hz.com/centos/7/stable/2600hz-release/4.3/2600hz-release-4.3-0.el7.centos.noarch.rpm

export RELEASE_BASE=https://packages.2600hz.com/centos/7/stable/2600hz-release
export RELEASE_VER=4.3
export META_PKG=2600hz-release-${RELEASE_VER}-0.el7.centos.noarch.rpm
export LATEST_RELEASE=${RELEASE_BASE}/${RELEASE_VER}/${META_PKG}

# Install all system updates
yum update -y

# Install Extra Packages for Enterprise Linux
yum install -y epel-release

# Install required packages
yum install -y yum-utils psmisc

# Download and install updated FreeSWITCH repository
echo "signalwire" > /etc/yum/vars/signalwireusername
echo ${TOKEN} > /etc/yum/vars/signalwiretoken
wget https://$(< /etc/yum/vars/signalwireusername):$(< /etc/yum/vars/signalwiretoken)@freeswitch.signalwire.com/repo/yum/centos-release/freeswitch-release-repo-0-1.noarch.rpm
rpm -i --replacefiles freeswitch-release-repo-0-1.noarch.rpm

# Hostname setup
hostnamectl set-hostname ${_HOSTNAME}

echo "${IP_ADDR} ${_HOSTNAME} `hostname -s`" >> /etc/hosts
echo "127.0.0.1 ${_HOSTNAME} `hostname -s`" >> /etc/hosts
echo "::1 ${_HOSTNAME} `hostname -s`" >> /etc/hosts

# /etc/hosts setup
If you are running a multi-server environment, define the private IPs for your CouchDB servers and public IPs for your other Kazoo-apps/Kamailio/FreeSWITCH/RabbitMQ servers. An example would be:

127.0.0.1       app001.domain.com localhost localhost.localdomain localhost4 localhost4.localdomain4
::1             app001.domain.com localhost localhost.localdomain localhost4 localhost4.localdomain4
10.1.1.1        bc001.domain.com
10.1.1.2        bc002.domain.com
10.1.1.3        bc003.domain.com
38.222.222.222  fs001.domain.com
38.222.222.223  kam001.domain.com
38.222.222.225  rab001.domain.com

# System time to UTC: required by kazoo
ln -fs /usr/share/zoneinfo/UTC /etc/localtime

# Setup networking to auto-start (if necessary)
sed -i 's/ONBOOT=no/ONBOOT=yes/' /etc/sysconfig/network-scripts/ifcfg-eth0
systemctl restart network

# Add 2600Hz RPM server
yum install -y ${LATEST_RELEASE}
Example:  yum install -y https://packages.2600hz.com/centos/7/stable/2600hz-release/4.3/2600hz-release-4.3-0.el7.centos.noarch.rpm

# Clear yum cache
yum clean all

# Setup NTPd
yum install -y ntp
systemctl enable ntpd
systemctl restart ntpd

Setting up RabbitMQ#

# Install the Kazoo-wrapped RabbitMQ
# This installs an older (perfectly fine) version 3.3.5
yum install -y kazoo-rabbitmq

## If you want to run newer versions follow these steps:
## yum remove erlang erlang-* -y
## wget https://github.com/rabbitmq/erlang-rpm/releases/download/v20.3.8.15/erlang-20.3.8.15-1.el7.centos.x86_64.rpm
## yum install erlang-20.3.8.15-1.el7.centos.x86_64.rpm
## curl -s https://packagecloud.io/install/repositories/rabbitmq/rabbitmq-server/script.rpm.sh | sudo bash
## yum install rabbitmq-server-3.7.8-1.el7.noarch kazoo-rabbitmq-4.2-4.el7.centos.noarch -y
## sed -i s/',{loopback_users, \[\]}'/',{loopback_users, \[\]}\n,{channel_max, 0}'/g /etc/kazoo/rabbitmq/rabbitmq.config
## systemctl daemon-reload
## systemctl start kazoo-rabbitmq

# Enable and start
systemctl enable kazoo-rabbitmq
systemctl start kazoo-rabbitmq

# Check that RabbitMQ is listening
ss -lpn | grep "5672"

# For testing purposes (optional), it can be useful to disable iptables
systemctl stop firewalld

# Check the RabbitMQ UI (optional)
# http://${IP_ADDR}:15672/
# Use 'guest' as username and password

# Check out the API (optional, build monitoring tools around this)
curl -i -u guest:guest http://localhost:15672/api/aliveness-test/%2F

Setting up Kamailio#

# Install Kazoo-wrapped Kamailio
yum install -y kazoo-kamailio

# Update the hostname in the config
sed -i "s/kamailio\.2600hz\.com/${_HOSTNAME}/g" /etc/kazoo/kamailio/local.cfg

# Update the IP addresses
sed -i "s/127\.0\.0\.1/${IP_ADDR}/g" /etc/kazoo/kamailio/local.cfg

# Disable Kamailio bundled systemctl script
systemctl disable kamailio

# Note: If RabbitMQ is running on a separate server, update the local.cfg file (above):
# #!substdef "!MY_AMQP_URL!amqp://guest:guest@${RABBITMQ_IP_ADDR}:5672!g"

# Start Kamailio
systemctl enable kazoo-kamailio
systemctl restart kazoo-kamailio

# Check that Kamailio is listening (optional)
ss -ln | egrep "5060|7000"
udp    UNCONN     0      0         *:7000                  *:*

tcp    LISTEN     0      128       *:7000                  *:*

# check the dispatcher status
kazoo-kamailio status
error: 500 - No Destination Sets

## This error is expected! You haven't added any FreeSWITCH servers for Kamailio to use.

Setting up FreeSWITCH#

# Install Kazoo-wrapped FreeSWITCH
yum install -y kazoo-freeswitch

# Disable freeswitch bundled systemctl script
systemctl disable freeswitch

# Enable and start FreeSWITCH
systemctl enable kazoo-freeswitch
systemctl start kazoo-freeswitch

# Check FreeSWITCH status (you will not see any connected Erlang modules)

# Get the sipify script for FreeSWITCH log parsing (optional)
curl -o /usr/bin/sipify.sh \
https://raw.githubusercontent.com/2600hz/community-scripts/master/FreeSWITCH/sipify.sh
chmod 755 /usr/bin/sipify.sh

Note

mod_sofia isn't loaded on boot. FreeSWITCH is shipped with no dialplan as Kazoo itself controls all of the routing decisions, thus FreeSWITCH isn't of much use until Kazoo is connected.

Note

Kamailio will still not know about FreeSWITCH in the destination sets. FreeSWITCH will be auto-discovered later in the process and added.

Setting up BigCouch#

At this time, BigCouch is still "recommended" solely because we don't have the history in production of running CouchDB. Kazoo works just fine with CouchDB 1.6 and 2.0 so feel free to install and configure those packages instead.

# Install Kazoo-wrapped BigCouch
yum install -y kazoo-bigcouch

# Enable and start BigCouch
systemctl enable kazoo-bigcouch
systemctl start kazoo-bigcouch

# Check that BigCouch is listening (optional)
ss -ln | egrep "5984|5986"
tcp    LISTEN     0      128       *:5984                  *:*

# Check the BigCouch UI (optional): http://localhost:5984/_utils

# Check the status of bigcouch
kazoo-bigcouch status
BigCouch (pid 21325) is running...
{"all_nodes":["bigcouch@aio.kazoo.com"],"cluster_nodes":["bigcouch@aio.kazoo.com"]}

Setting up HAProxy#

# Install the Kazoo-wrapped HAProxy
yum -y install kazoo-haproxy socat

# Edit /etc/kazoo/haproxy/haproxy.cfg to setup the backend server to point to BigCouch
# For AiO installs, it should look something like:

cat >> /etc/kazoo/haproxy/haproxy.cfg << EOF

Setting up Kazoo Applications#

At this point, we're ready to install Kazoo as all the infrastructure that Kazoo relies on is in place and ready to be taken control of. The first thing to do is install the Kazoo applications.

# Install all the Kazoo applications (at this time, 4.3.36 for most of the kazoo-application-* packages)
yum install -y kazoo-applications

# Start Kazoo Applications
systemctl enable kazoo-applications
systemctl start kazoo-applications

# Check that the databases are created (may take some time while things initialize)
# Results may vary a bit - should be at least 5 system databases for sure)
curl localhost:15984/_all_dbs
["accounts","acdc","alerts","anonymous_cdrs","dedicated_ips","faxes","global_provisioner","oauth","offnet","pending_notifications","port_requests","ratedeck","services","sip_auth","system_auth","system_config","system_data","system_media","system_schemas","tasks","token_auth","webhooks"]

# You should have > 20 DBs
curl localhost:15984/_all_dbs | python -mjson.tool | wc -l
26

# Import System Media prompts (takes a while)
sup kazoo_media_maintenance import_prompts /opt/kazoo/sounds/en/us/

# If you need to import other languages (optional)
# sup kazoo_media_maintenance import_prompts /opt/kazoo/sounds/fr/ca fr-ca

# It can be a good idea to run a refresh over the installed databases - there are sporadic reports of partial installations hanging at this point
sup kapps_maintenance refresh

Troubleshooting#

Kamailio#

There was an issue with librabbitmq versions when installing/updating kazoo-kamailio. If you see something like:

Error: Package: kamailio-kazoo-5.0.4j-3.1.x86_64 (2600hz-stable)
           Requires: librabbitmq.so.1()(64bit)

You can workaround this by disabling the base repo (hat-tip btel):

yum remove librabbitmq
yum --disablerepo="*" --enablerepo=epel install librabbitmq
yum install kazoo-kamailio

CouchDB / Bigcouch#

If creating the first account fails, or you see the following in /var/log/bigcouch/bigcouch.log:

[Tue, 15 May 2018 04:03:03 GMT] [info] [<0.124.0>] [--------] couch_proc_manager <0.3773.0> died normal
[Tue, 15 May 2018 04:03:03 GMT] [error] [<0.254.0>] [941cd296] OS Process Error <0.3792.0> :: {<<"unnamed_error">>,
                                                               <<"(new TypeError(\"cmd is undefined\", \"/opt/bigcouch/share/couchjs/main.js\", 1474))">>}
[Tue, 15 May 2018 04:03:03 GMT] [info] [<0.124.0>] [--------] couch_proc_manager <0.3781.0> died normal

This was caused by a CentOS update to the js package from 1.8.5-19 to -20.

2600Hz is hosting the -19 version now; if you've installed -20 you'll need to downgrade:

yum downgrade js-1:1.8.5-19.el7.x86_64

See the CouchDB issue if you want more info.
