Prerequisites
1.Create the database, complete these steps:
mysql -uroot -p1234qwer CREATE DATABASE octavia; GRANT ALL PRIVILEGES ON octavia.* TO 'octavia'@'localhost' IDENTIFIED BY 'OCTAVIA_DBPASS'; GRANT ALL PRIVILEGES ON octavia.* TO 'octavia'@'%' IDENTIFIED BY 'OCTAVIA_DBPASS'; quit
2.To create the Octavia service credentials, complete these steps:
openstack user create --domain default --password octavia123 octavia openstack role add --project admin --user octavia admin openstack service create --name octavia --description "OpenStack Octavia" load-balancer
3.Create the Load-balancer service API endpoints:
openstack endpoint create --region RegionOne load-balancer public http://controller:9876 openstack endpoint create --region RegionOne load-balancer internal http://controller:9876 openstack endpoint create --region RegionOne load-balancer admin http://controller:9876
4.Create the amphora image
git clone https://github.com/openstack/octavia.git -b stable/train yum -y install python2-pip qemu-img git e2fsprogs policycoreutils-python debootstrap libguestfs-tools virt-install.noarch python-virtualenv virtualenv octavia_disk_image_create source octavia_disk_image_create/bin/activate cd octavia/diskimage-create/ wget https://cloud.centos.org/centos/7/images/CentOS-7-x86_64-GenericCloud.qcow2 systemctl restart libvirtd;systemctl enable libvirtd export LIBGUESTFS_BACKEND=direct export DIB_REPOREF_amphora_agent=stable/train export DIB_LOCAL_IMAGE=/root/octavia/diskimage-create/CentOS-7-x86_64-GenericCloud.qcow2 virt-customize -a /root/octavia/diskimage-create/CentOS-7-x86_64-GenericCloud.qcow2 --selinux-relabel --run-command 'yum install -y centos-release-openstack-train telnet traceroute bind-utils' virtualenv octavia_disk_image_create source octavia_disk_image_create/bin/activate cd octavia/diskimage-create pip install -r requirements.txt ./diskimage-create.sh -r 1234qwer -i centos-minimal -s 4
5.Upload the amphora image
openstack image create --disk-format qcow2 --container-format bare --private --tag amphora --file /root/octavia/diskimage-create/amphora-x64-haproxy.qcow2 amphora-x64-haproxy
6.Create a flavor for the amphora image
openstack flavor create --id 200 --vcpus 1 --ram 1024 --disk 2 "amphora" --private
Install and configure components
1.Install the packages:
yum -y install openstack-octavia-api openstack-octavia-health-manager openstack-octavia-housekeeping openstack-octavia-worker python-octavia python-octaviaclient
2.Create the certificates
git clone https://opendev.org/openstack/octavia.git cd octavia/bin/ source create_dual_intermediate_CA.sh sudo mkdir -p /etc/octavia/certs/private sudo chmod 755 /etc/octavia -R sudo cp -p etc/octavia/certs/server_ca.cert.pem /etc/octavia/certs sudo cp -p etc/octavia/certs/server_ca-chain.cert.pem /etc/octavia/certs sudo cp -p etc/octavia/certs/server_ca.key.pem /etc/octavia/certs/private sudo cp -p etc/octavia/certs/client_ca.cert.pem /etc/octavia/certs sudo cp -p etc/octavia/certs/client.cert-and-key.pem /etc/octavia/certs/private chown octavia:octavia -R /etc/octavia/certs/
3.Create security groups and their rules
openstack security group create lb-mgmt-sec-grp openstack security group rule create --protocol icmp lb-mgmt-sec-grp openstack security group rule create --protocol tcp --dst-port 22 lb-mgmt-sec-grp openstack security group rule create --protocol tcp --dst-port 9443 lb-mgmt-sec-grp openstack security group create lb-health-mgr-sec-grp openstack security group rule create --protocol udp --dst-port 5555 lb-health-mgr-sec-grp
4.Create a key pair for logging in to the amphora instance
ssh-keygen openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey
5.Create dhclient.conf file for dhclient

cd $HOME sudo mkdir -m755 -p /etc/dhcp/octavia sudo cp octavia/etc/dhcp/dhclient.conf /etc/dhcp/octavia
6.Create a network
openstack network create lb-mgmt-net openstack subnet create --subnet-range 192.168.0.0/24 --allocation-pool start=192.168.0.100,end=192.168.0.200 --network lb-mgmt-net lb-mgmt-subnet OCTAVIA_MGMT_PORT_IP=192.168.0.2 SUBNET_ID=$(openstack subnet show lb-mgmt-subnet -f value -c id) PORT_FIXED_IP="--fixed-ip subnet=$SUBNET_ID,ip-address=$OCTAVIA_MGMT_PORT_IP" MGMT_PORT_ID=$(openstack port create --security-group lb-health-mgr-sec-grp --device-owner Octavia:health-mgr --host=$(hostname) -c id -f value --network lb-mgmt-net $PORT_FIXED_IP octavia-health-manager-listen-port) MGMT_PORT_MAC=$(openstack port show -c mac_address -f value $MGMT_PORT_ID) ip link add o-hm0 type veth peer name o-bhm0 NETID=$(openstack network show lb-mgmt-net -c id -f value) BRNAME=brq$(echo $NETID|cut -c 1-11) brctl addif $BRNAME o-bhm0 ip link set o-bhm0 up ip link set dev o-hm0 address $MGMT_PORT_MAC dhclient -v o-hm0 -cf /etc/dhcp/octavia
7.Edit the /etc/octavia/octavia.conf file
openstack project list
amp_image_owner_id = eec492e093a6451983958244799e4175
openstack security group list
amp_secgroup_list = 55235a38-2f54-49b4-83e8-4e9c61d752a8
openstack network list
amp_boot_network_list = 25dc889f-a8f4-4b74-8674-f2428004deb0
amp_image_owner_id=$(openstack project list|grep admin|awk '{print $2}')
amp_secgroup_list=$(openstack security group list|grep lb-mgmt-sec-grp|awk '{print $2}')
amp_boot_network_list=$(openstack network list|grep lb-mgmt-net|awk '{print $2}')
