FreeIPAとAmbari連携

FreeIPAとAmbariの連携方法をメモしておきます。
HDP3.1.0、Ambari 2.7.3の環境です。

FreeIPAのインストール

以下のスクリプトでサーバー上にインストールし、いくつかUser、Groupを作成する。
必要に応じて変更してください。

#ホスト名
export NAME=ipa-srv1
#Domain名
export DOMAIN=demotest.com
export REALM=$(echo ${DOMAIN} | awk '{print toupper($0)}')
export IP=$(ip addr | grep 'state UP' -A2 | tail -n1 | awk '{print $2}' | cut -f1 -d'/')

echo "IP is ${IP}"

echo "${IP} ${NAME}.${DOMAIN} ${NAME} $(hostname -f) $(hostname -s)" >> /etc/hosts
hostnamectl set-hostname ${NAME}.${DOMAIN}
hostnamectl --transient set-hostname ${NAME}
hostname ${NAME}.${DOMAIN}
echo 0 > /proc/sys/kernel/hung_task_timeout_secs
ethtool -K eth0 tso off


hostname -f
cat /etc/hosts

#install packages
sudo yum install ipa-server ipa-server-dns -y

#increase entropy
cat /proc/sys/kernel/random/entropy_avail
sudo yum install -y rng-tools
sudo systemctl start rngd
cat /proc/sys/kernel/random/entropy_avail

#sometimes needed to avoid server install failing
sudo service dbus restart

#install IPA server
