Add MariaDB repository as we need v10.5
wget https://downloads.mariadb.com/MariaDB/mariadb_repo_setup chmod +x mariadb_repo_setup ./mariadb_repo_setup --mariadb-server-version="mariadb-10.5" apt update apt -y upgrade apt install -y mariadb-server python-pymysql
Create /etc/mysql/mariadb.conf.d/99-openstack.cnf with following contents. Note : since I had enough memory in controller node set the value of buffer pool size.
[mysqld] bind-address = 10.1.1.60 innodb_buffer_pool_size = 8G default-storage-engine = innodb innodb_file_per_table = on max_connections = 4096 collation-server = utf8_general_ci character-set-server = utf8
Restart service, set password for root user, and disable root user login from remote system
service mysql restart mysql_secure_installation
Install message queue component, add user account and set permissions
apt install -y rabbitmq-server rabbitmqctl add_user openstack commonpass rabbitmqctl set_permissions openstack ".*" ".*" ".*" systemctl enable rabbitmq-server.service
Install memcached
apt install -y memcached python-memcache
Edit the /etc/memcached.conf file and configure the service to use the management IP address of the controller node. This is to enable access by other nodes via the management network. Replace -l 127.0.0.1 to -l 10.1.1.60 (management ip address of controller node) and restart memcached
systemctl enable memcached service memcached restart
Install etcd
apt install -y etcd
Edit the /etc/default/etcd file and set the ETCD_INITIAL_CLUSTER, ETCD_INITIAL_ADVERTISE_PEER_URLS, ETCD_ADVERTISE_CLIENT_URLS, ETCD_LISTEN_CLIENT_URLS to the management IP address of the controller node to enable access by other nodes via the management network. All default configurations were commented. So added the following
ETCD_NAME="controller" ETCD_DATA_DIR="/var/lib/etcd" ETCD_INITIAL_CLUSTER_STATE="new" ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster-01" ETCD_INITIAL_CLUSTER="controller=http://10.1.1.60:2380" ETCD_INITIAL_ADVERTISE_PEER_URLS="http://10.1.1.60:2380" ETCD_ADVERTISE_CLIENT_URLS="http://10.1.1.60:2379" ETCD_LISTEN_PEER_URLS="http://0.0.0.0:2380" ETCD_LISTEN_CLIENT_URLS="http://10.1.1.60:2379"
Restart etcd
systemctl enable etcd systemctl restart etcd
