iaas安装部署 openstack openstack ussuri安装部署

注：1.octavia源码下载地址：

    cd /home

    git clone https://github.com/openstack/octavia.git-b stable/ussuri    #证书

    git clone https://github.com/openstack/octavia-dashboard.gitussuri    #在dashboard中添加loadbalancer

注：如各节点重启后需重新配置o-hm0网卡ip和mac

主节点（controller1）基础配置

一、创建数据库

mysql -uroot -p123456 CREATE DATABASE octavia; GRANT ALL PRIVILEGES ON octavia.* TO 'octavia'@'localhost' IDENTIFIED BY '123456'; GRANT ALL PRIVILEGES ON octavia.* TO 'octavia'@'%' IDENTIFIED BY '123456'; flush privileges; exit;

二、安装软件包

yum -y install\ openstack-octavia-api.noarch\ openstack-octavia-common.noarch \ openstack-octavia-health-manager.noarch \ openstack-octavia-housekeeping.noarch \ openstack-octavia-worker.noarch \ python3-octaviaclient.noarch

三、创建keystone认证体系（用户、角色、endpoint）

openstack user create --domain default --password 123456 octavia openstack role add --project service --user octavia admin openstack service create load-balancer --name octavia openstack endpoint create octavia public http://controller1:9876 --region RegionOne openstack endpoint create octavia admin http://controller1:9876 --region RegionOne openstack endpoint create octavia internal http://controller1:9876 --region RegionOne

四、导入Amphora镜像，按需求创建实例类型

# 先下载U版镜像 https://tarballs.opendev.org/openstack/octavia/test-images/test-only-amphora-x64-haproxy-centos-8.qcow2 # source service octavia的环境变量 export OS_USERNAME=octavia export OS_PASSWORD=123456 export OS_PROJECT_NAME=service export OS_USER_DOMAIN_NAME=Default export OS_PROJECT_DOMAIN_NAME=Default export OS_AUTH_URL=http://controller1:5000/v3 export OS_IDENTITY_API_VERSION=3 # 上传镜像 openstack image create amphora-x64-haproxy --public --container-format=bare \ --disk-format qcow2 --file test-only-amphora-x64-haproxy-centos-8.qcow2 --tag amphora # 创建实例类型 openstack flavor create --ram 4096 --disk 50 --vcpus 2 flavor

五、创建安全组

# Amphora 虚拟机使用，LB Network 与 Amphora 通信，分别为service下的安全组添加规则

openstack security group create lb-mgmt-sec-grp --project service openstack security group rule create --protocol udp --dst-port 5555 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 rule create --protocol icmp lb-mgmt-sec-grp

# Amphora 虚拟机使用，Health Manager 与 Amphora 通信，分别为service下的安全组添加规则

openstack security group create lb-health-mgr-sec-grp --project service openstack security group rule create --protocol udp --dst-port 5555 lb-health-mgr-sec-grp openstack security group rule create --protocol tcp --dst-port 22 lb-health-mgr-sec-grp openstack security group rule create --protocol tcp --dst-port 9443 lb-health-mgr-sec-grp

六、创建管理网络（注意要指定租户）

openstack network create lb-mgmt-net --project service openstack subnet create --subnet-range 192.168.0.0/24 --allocation-pool \ start=192.168.0.2,end=192.168.0.100 --network lb-mgmt-net lb-mgmt-subnet

七、创建管理端口

openstack port create octavia-health-manager-standalone-listen-port \ --security-group lb-health-mgr-sec-grp \ --device-owner Octavia:health-mgr \ --host <hostname> --network lb-mgmt-net \ --project service ovs-vsctl --may-exist add-port br-int o-hm0 \ -- set Interface o-hm0 type=internal \ -- set Interface o-hm0 external-ids:iface-status=active \ -- set Interface o-hm0 external-ids:attached-mac=<Health Manager Listen Port MAC> \ -- set Interface o-hm0 external-ids:iface-id=<Health Manager Listen Port ID>

八、为管理端口设置ip（Health Manager 监听端口设置 IP）

ip link set dev o-hm0 address <Health Manager Listen Port MAC> ip addr add <Health Manager Listen Port IP/24> dev o-hm0 #<>处是添加ip和子网 ip link set dev o-hm0 up #启动网卡使配置生效

 

九、生成octavia controller与amphora通信的证书

U版的证书生成脚本不会用 - - 手动生成

# 注意，以下所有让输入pass密码的，直接输入123456回车 # 让输入其他参数的直接回车 cd /home mkdir certs chmod 700 certs cd certs cp /home/octavia/bin/openssl.cnf ./ mkdir client_ca mkdir server_ca cd server_ca mkdir certs crl newcerts private chmod 700 private touch index.txt echo 1000 > serial openssl genrsa -aes256 -out private/ca.key.pem 4096 chmod 400 private/ca.key.pem openssl req -config ../openssl.cnf -key private/ca.key.pem -new -x509 -days \ 7300 -sha256 -extensions v3_ca -out certs/ca.cert.pem cd ../client_ca mkdir certs crl csr newcerts private chmod 700 private touch index.txt echo 1000 > serial openssl genrsa -aes256 -out private/ca.key.pem 4096 chmod 400 private/ca.key.pem openssl req -config ../openssl.cnf -key private/ca.key.pem -new -x509 -days 7300 \ -sha256 -extensions v3_ca -out certs/ca.cert.pem openssl genrsa -aes256 -out private/client.key.pem 2048 openssl req -config ../openssl.cnf -new -sha256 -key private/client.key.pem -out \ csr/client.csr.pem openssl ca -config ../openssl.cnf -extensions usr_cert -days 7300 -notext \ -md sha256 -in csr/client.csr.pem -out certs/client.cert.pem openssl rsa -in private/client.key.pem -out private/client.cert-and-key.pem cat certs/client.cert.pem >> private/client.cert-and-key.pem cd .. mkdir /etc/octavia/certs chmod 700 /etc/octavia/certs cp server_ca/private/ca.key.pem /etc/octavia/certs/server_ca.key.pem chmod 700 /etc/octavia/certs/server_ca.key.pem cp server_ca/certs/ca.cert.pem /etc/octavia/certs/server_ca.cert.pem cp client_ca/certs/ca.cert.pem /etc/octavia/certs/client_ca.cert.pem cp client_ca/private/client.cert-and-key.pem /etc/octavia/certs/client.cert-and-key.pem chmod 700 /etc/octavia/certs/client.cert-and-key.pem chown -R octavia.octavia /etc/octavia/certs

十、创建密钥对

mkdir -p /etc/octavia/.ssh ssh-keygen -b 2048 -t rsa -N "" -f /etc/octavia/.ssh/octavia_ssh_key nova keypair-add --pub-key=/etc/octavia/.ssh/octavia_ssh_key.pub octavia_ssh_key --user {octavia_user_id}

修改配置文件

十一、修改配置文件

#/etc/octavia/octavia.conf [DEFAULT] transport_url = rabbit://openstack:openstack@controller1:5672, \ openstack:openstack@controller2:5672,openstack:openstack@controller3:5672 [api_settings] bind_host = 172.27.125.201 <host IP> bind_port = 9876 api_handler = queue_producer auth_strategy = keystone [database] connection = mysql+pymysql://octavia:123456@controller1:3306/octavia [health_manager] bind_ip = 192.168.0.12 <Health Manager Listen Port IP> bind_port = 5555 controller_ip_port_list = 192.168.0.12:5555, 192.168.0.*:5555, \ <ha环境需填写其余节点的网卡ip:端口> heartbeat_key = insecure [keystone_authtoken] auth_uri = http://172.27.125.106:5000 auth_url = http://172.27.125.106:5000 memcached_servers = controller1:11211,controller2:11211,controller3:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = octavia password = 123456 [certificates] cert_generator = local_cert_generator ca_private_key_passphrase = 123456 ca_private_key = /etc/octavia/certs/server_ca.key.pem ca_certificate = /etc/octavia/certs/server_ca.cert.pem [haproxy_amphora] client_cert = /etc/octavia/certs/client.cert-and-key.pem server_ca = /etc/octavia/certs/server_ca.cert.pem key_path = /etc/octavia/.ssh/octavia_ssh_key base_path = /var/lib/octavia base_cert_dir = /var/lib/octavia/certs connection_max_retries = 5500 connection_retry_interval = 5 rest_request_conn_timeout = 10 rest_request_read_timeout = 120 [controller_worker] client_ca = /etc/octavia/certs/client_ca.cert.pem # <openstack image list查看第三步上传镜像时的tag标签> amp_image_tag = amphora # <openstack image show查看第三步创建镜像的owner id（请注意是owner的id）> amp_image_owner_id = 22d71ab1b5b548f7b076b61e7c3ed7dc # <openstack flavor list查看第三步创建的实例类型id> amp_flavor_id = c6cc5162-26cb-4e98-aa49-efb3eb369eb2 # <openstack security group list查看第五步创建的lb-mgmt-sec-grp id> amp_secgroup_list = 0428056a-f1fb-457e-bd33-c2d23eb6d2cd # <openstack network list查看第六步创建的lb-mgmt-net id> amp_boot_network_list = 450227cc-11e8-4422-8bf5-540ef5cb2dfe amp_ssh_key_name = octavia_ssh_key network_driver = allowed_address_pairs_driver compute_driver = compute_nova_driver amphora_driver = amphora_haproxy_rest_driver # 物理环境下可以不用配置此项,如果在虚拟机环境中部署可适当调整下面两个参数 workers = 2 # 物理环境下可以不用配置此项 amp_active_retries = 100 # 物理环境下可以不用配置此项 amp_active_wait_sec = 2 loadbalancer_topology = ACTIVE_STANDBY [oslo_messaging] topic = octavia_prov rpc_thread_pool_size = 2 [house_keeping] load_balancer_expiry_age = 3600 amphora_expiry_age = 3600 [service_auth] memcached_servers = controller1:11211,controller2:11211,controller3:11211 project_domain_name = default project_name = service user_domain_name = default password = 123456 username = octavia auth_type = password auth_url = http://172.27.125.106:5000 auth_uri = http://172.27.125.106:5000

十二、初始化octavia数据库

octavia-db-manage upgrade head

十三、启动服务

#重启octavia各组件

（如果使用httpd纳管octavia-api，就需要stop并disable octavia-api防止octavia发生端口冲突）

systemctl restart octavia-api.service systemctl restart octavia-worker.service systemctl restart octavia-health-manager.service systemctl restart octavia-housekeeping.service

#设为开机启动

systemctl enable octavia-api.service systemctl enable octavia-worker.service systemctl enable octavia-health-manager.service systemctl enable octavia-housekeeping.service

十四、添加 Load Balancers 页面

cd octavia_file/octavia-dashboard python setup.py install cd octavia_dashboard/enabled/ cp _1482_project_load_balancer_panel.py /usr/share/openstack-dashboard/openstack_dashboard/enabled/ cd /usr/share/openstack-dashboard ./manage.py collectstatic ./manage.py compress systemctl restart httpd

其余节点（controller2/3）基础配置

一、安装软件包

yum -y install\ openstack-octavia-api.noarch\ openstack-octavia-common.noarch \ openstack-octavia-health-manager.noarch \ openstack-octavia-housekeeping.noarch \ openstack-octavia-worker.noarch \ python2-octaviaclient.noarch

 

二、创建管理端口

openstack port create octavia-health-manager-standalone-listen-port \ --security-group lb-health-mgr-sec-grp \ --device-owner Octavia:health-mgr \ --host <hostname> --network lb-mgmt-net \ --project service ovs-vsctl --may-exist add-port br-int o-hm0 \ -- set Interface o-hm0 type=internal \ -- set Interface o-hm0 external-ids:iface-status=active \ -- set Interface o-hm0 external-ids:attached-mac=<Health Manager Listen Port MAC> \ -- set Interface o-hm0 external-ids:iface-id=<Health Manager Listen Port ID>

三、为管理端口设置IP

ip link set dev o-hm0 address <Health Manager Listen Port MAC> ip addr add <ip-addr/24> dev o-hm0 ip link set dev o-hm0 up

四、复制主节点controller1上已经生成的证书和秘钥

mkdir -p /etc/octavia/.ssh/ mkdir -p /etc/octavia/certs/ 进入controller1中把目录/etc/octavia/certs和/etc/octavia/.ssh下的文件打包传输的其余各节点中的对应文件夹下 chown octavia:octavia /etc/octavia/certs -R

五、修改配置文件

#/etc/octavia/octavia.conf [DEFAULT] transport_url = rabbit://openstack:openstack@controller1:5672, \ openstack:openstack@controller2:5672,openstack:openstack@controller3:5672 [api_settings] bind_host = 172.27.125.202 <host IP> bind_port = 9876 api_handler = queue_producer auth_strategy = keystone [database] connection = mysql+pymysql://octavia:123456@controller2:3306/octavia [health_manager] bind_ip = 192.168.0.* <Health Manager Listen Port IP> bind_port = 5555 # <ha环境需填写其余节点的网卡ip:端口> controller_ip_port_list = 192.168.0.11:5555, 192.168.0.*:5555 heartbeat_key = insecure [keystone_authtoken] auth_uri = http://172.27.125.106:5000 auth_url = http://172.27.125.106:5000 memcached_servers = controller1:11211,controller2:11211,controller3:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = octavia password = 123456 [certificates] cert_generator = local_cert_generator ca_private_key_passphrase = 123456 ca_private_key = /etc/octavia/certs/server_ca.key.pem ca_certificate = /etc/octavia/certs/server_ca.cert.pem [haproxy_amphora] client_cert = /etc/octavia/certs/client.cert-and-key.pem server_ca = /etc/octavia/certs/server_ca.cert.pem key_path = /etc/octavia/.ssh/octavia_ssh_key base_path = /var/lib/octavia base_cert_dir = /var/lib/octavia/certs connection_max_retries = 5500 connection_retry_interval = 5 rest_request_conn_timeout = 10 rest_request_read_timeout = 120 [controller_worker] client_ca = /etc/octavia/certs/client_ca.cert.pem amp_image_tag = amphora # <openstack image show IMAGE_ID 查看第三步创建镜像的owner id（请注意是owner的id）> amp_image_owner_id = 22d71ab1b5b548f7b076b61e7c3ed7dc # <openstack flavor list查看第三步创建的实例类型id> amp_flavor_id = c6cc5162-26cb-4e98-aa49-efb3eb369eb2 # <openstack security group list查看第五步创建的lb-mgmt-sec-grp id> amp_secgroup_list = 0428056a-f1fb-457e-bd33-c2d23eb6d2cd # <openstack network list查看第六步创建的lb-mgmt-net id> amp_boot_network_list = 450227cc-11e8-4422-8bf5-540ef5cb2dfe amp_ssh_key_name = octavia_ssh_key network_driver = allowed_address_pairs_driver compute_driver = compute_nova_driver amphora_driver = amphora_haproxy_rest_driver workers = 2 amp_active_retries = 100 amp_active_wait_sec = 2 loadbalancer_topology = ACTIVE_STANDBY [oslo_messaging] topic = octavia_prov rpc_thread_pool_size = 2 [house_keeping] load_balancer_expiry_age = 3600 amphora_expiry_age = 3600 [service_auth] memcached_servers = controller1:11211,controller2:11211,controller3:11211 project_domain_name = default project_name = service user_domain_name = default password = 123456 username = octavia auth_type = password auth_url = http://172.27.125.106:5000 auth_uri = http://172.27.125.106:5000

六、初始化octavia数据库

 

octavia-db-manage upgrade head

七、启动服务

（如果使用httpd纳管octavia-api，就需要stop并disable octavia-api防止octavia发生端口冲突）

#重启octavia各组件

systemctl restart octavia-api.service systemctl restart octavia-worker.service systemctl restart octavia-health-manager.service systemctl restart octavia-housekeeping.service
