OpenStack Train版简单部署流程（4）- octavia

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
##创建镜像
systemctl restart libvirtd;systemctl enable libvirtd
git clone https://github.com/openstack/octavia.git -b stable/train
virtualenv octavia_disk_image_create
source octavia_disk_image_create/bin/activate
cd octavia/diskimage-create/
pip install -r requirements.txt
./diskimage-create.sh -i centos-minimal -t qcow2 -o amphora-x64-haproxy -r 1234qwer -s 4

5.Upload the amphora image

cat << EOF >> $HOME/octavia-openrc
export OS_PROJECT_DOMAIN_NAME=default
export OS_USER_DOMAIN_NAME=default
export OS_PROJECT_NAME=admin
export OS_USERNAME=octavia
export OS_PASSWORD=octavia123
export OS_AUTH_URL=http://controller:5000
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
export OS_VOLUME_API_VERSION=3
EOF

. $HOME/octavia-openrc
openstack image create --disk-format qcow2 --container-format bare --private --tag amphora --file 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 5 "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

chmod 700 /etc/octavia/certs/client.cert-and-key.pem
chown -R octavia.octavia /etc/octavia/certs

3.Create security groups and their rules

. $HOME/octavia-openrc
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

OCTAVIA_MGMT_SUBNET=172.16.0.0/12
OCTAVIA_MGMT_SUBNET_START=172.16.0.100
OCTAVIA_MGMT_SUBNET_END=172.16.31.254
OCTAVIA_MGMT_PORT_IP=172.16.0.2

openstack network create lb-mgmt-net
openstack subnet create --subnet-range $OCTAVIA_MGMT_SUBNET --allocation-pool \
start=$OCTAVIA_MGMT_SUBNET_START,end=$OCTAVIA_MGMT_SUBNET_END \
--network lb-mgmt-net lb-mgmt-subnet

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)

MGMT_PORT_IP=$(openstack port show -f yaml -c fixed_ips \
$MGMT_PORT_ID | awk '{FS=",|";gsub(",","");gsub("'\''",""); \
for(line = 1; line <= NF; ++line) {if ($line ~ /^- ip_address:/) \
{split($line, word, " ");if (ENVIRON["IPV6_ENABLED"] == "" && word[3] ~ /\./) \
print word[3];if (ENVIRON["IPV6_ENABLED"] != "" && word[3] ~ /:/) print word[3];} \
else {split($line, word, " ");for(ind in word) {if (word[ind] ~ /^ip_address=/) \
{split(word[ind], token, "=");if (ENVIRON["IPV6_ENABLED"] == "" && token[2] ~ /\./) \
print token[2];if (ENVIRON["IPV6_ENABLED"] != "" && token[2] ~ /:/) print token[2];}}}}}')

sudo 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)
sudo brctl addif $BRNAME o-bhm0
sudo ip link set o-bhm0 up

sudo ip link set dev o-hm0 address $MGMT_PORT_MAC
sudo iptables -I INPUT -i o-hm0 -p udp --dport 5555 -j ACCEPT
sudo 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

8.Populate the octavia database:

octavia-db-manage --config-file /etc/octavia/octavia.conf upgrade head
systemctl enable octavia-api octavia-health-manager octavia-housekeeping octavia-worker
systemctl restart octavia-api octavia-health-manager octavia-housekeeping octavia-worker
systemctl status octavia-api octavia-health-manager octavia-housekeeping octavia-worker

添加 Load Balancers 页面

git clone https://github.com/openstack/octavia-dashboard.git -b stable/train
cd /root/octavia-dashboard
python setup.py install
cd /root/octavia-dashboard/octavia_dashboard/enabled
cp _1482_project_load_balancer_panel.py /usr/share/openstack-dashboard/openstack_dashboard/enabled/
cd /usr/share/openstack-dashboard
echo yes|./manage.py collectstatic
./manage.py compress
systemctl restart httpd

重启创建 veth pair 脚本

Below settings are required to create veth pair after the host reboot

1.Edit the /etc/systemd/network/o-hm0.network file

mkdir -p /etc/systemd/network/
cat >>/etc/systemd/network/o-hm0.network<<EOF
[Match]
Name=o-hm0

[Network]
DHCP=yes
EOF

2.Edit the /etc/systemd/system/octavia-interface.service file

cat >>/etc/systemd/system/octavia-interface.service<<EOF
[Unit]
Description=Octavia Interface Creator
Requires=neutron-linuxbridge-agent.service
After=neutron-linuxbridge-agent.service

[Service]
Type=oneshot
RemainAfterExit=true
ExecStart=/opt/octavia-interface.sh start
ExecStop=/opt/octavia-interface.sh stop

[Install]
WantedBy=multi-user.target
EOF

3.Edit the /opt/octavia-interface.sh file

cat >>/opt/octavia-interface.sh<<EOF
#!/bin/bash

set -ex

MGMT_PORT_ID=$(openstack port list|grep octavia-health-manager-listen-port|awk '{print$2}')
MAC=$(openstack port show -c mac_address -f value $MGMT_PORT_ID)
NETID=$(openstack network show lb-mgmt-net -c id -f value)
BRNAME=brq$(echo $NETID|cut -c 1-11)

if [ "$1" == "start" ]; then
  ip link add o-hm0 type veth peer name o-bhm0
  brctl addif $BRNAME o-bhm0
  ip link set o-bhm0 up
  ip link set dev o-hm0 address $MAC
  ip link set o-hm0 up
  iptables -I INPUT -i o-hm0 -p udp --dport 5555 -j ACCEPT
elif [ "$1" == "stop" ]; then
  ip link del o-hm0
else
  brctl show $BRNAME
  ip a s dev o-hm0
fi
EOF

重启之后执行脚本

cd /opt
sh octavia-interface.sh start
sudo dhclient -v o-hm0 -cf /etc/dhcp/octavia
