Centos7.6安装Openstack

标签：-- CONFIG repo yum INSTALL openstack Openstack 安装 Centos7.6

1.主机配置

关闭防火墙

# 关闭防火墙
systemctl stop firewalld
# 开机禁止启动
systemctl disable firewalld

关闭selinux

vi /etc/sysconfig/selinux
在第7行设置
SELINUX=disabled
setenforce 0 # 临时生效，如果忘记设置，后续Httpd服务会因为权限问题无法启动

修改主机名

hostnamectl set-hostname controller

关闭NetworkManager

systemctl stop NetworkManager
systemctl disable NetworkManager

配置阿里源

yum -y install wget
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
yum clean all
yum makecache

配置时间同步

yum -y install ntpdate
ntpdate ntp1.aliyun.com

配置主机名映射

vi /etc/hosts
192.168.64.104 controller

2.安装

安装Rdo依赖

yum install -y https://rdoproject.org/repos/rdo-release.rpm

安装packstack

yum install -y openstack-packstack

配置rdo-release源为阿里源

vi /etc/yum.repos.d/rdo-release.repo

# 打开baseurl 并注释掉mirrorlist
[openstack-train]
name=OpenStack Train Repository
baseurl=http://mirrors.aliyun.com/centos/7/cloud/x86_64/openstack-train/
# mirrorlist=http://mirrorlist.centos.org/?release=7&arch=$basearch&repo=cloud-openstack-train
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-Cloud

生成应答文件

packstack --gen-answer-file=/root/test-answer.ini

修改应答文件

CONFIG_DEFAULT_PASSWORD=123456    
CONFIG_MANILA_INSTALL=n
CONFIG_NOVA_INSTALL=y
CONFIG_NEUTRON_INSTALL=y
CONFIG_HORIZON_INSTALL=y
CONFIG_SWIFT_INSTALL=n
CONFIG_CEILOMETER_INSTALL=n
CONFIG_AODH_INSTALL=n
CONFIG_PANKO_INSTALL=n
CONFIG_SAHARA_INSTALL=n
CONFIG_HEAT_INSTALL=n
CONFIG_MAGNUM_INSTALL=n
CONFIG_TROVE_INSTALL=n
CONFIG_IRONIC_INSTALL=n
CONFIG_CLIENT_INSTALL=y
CONFIG_DEBUG_MODE=n
CONFIG_CONTROLLER_HOST=9.111.x.x       这个就是controller节点的地址，一般就是主节点的地址，主节点意思就是选择一个资源比较好的节点充当主节点
CONFIG_COMPUTE_HOSTS=9.111.x.x, 9.111.x.x 这个是compute节点的地址，一般就是除了主节点剩下的地址，如果你只有两台，那么就两台节点地址都写上，用逗号隔开
CONFIG_NETWORK_HOSTS=9.111.x.x       这个是network节点的地址，一般就是主节点的地址
CONFIG_VMWARE_BACKEND=n
CONFIG_STORAGE_HOST=9.111.x.x     
CONFIG_SAHARA_HOST=9.111.x.x    这个和上面那个注释写的不支持了，所以就别管
CONFIG_MARIADB_HOST=9.111.x.x   这个就是openstack的数据库的地址，一般就是主节点的地址
CONFIG_MARIADB_USER=root     openstack数据库的用户名
CONFIG_MARIADB_PW=xxx       openstack数据库的密码
CONFIG_KEYSTONE_DB_PW=xxx    这个密码就整个统一的密码
CONFIG_KEYSTONE_ADMIN_USERNAME=admin    这个是安装之后dashboard的登录名，建议不改
CONFIG_KEYSTONE_ADMIN_PW=xxx          这个是安装之后dashboard的登录密码，改成统一的密码
CONFIG_NEUTRON_ML2_TYPE_DRIVERS=vxlan,flat  这块加
CONFIG_NEUTRON_ML2_TENANT_NETWORK_TYPES=vxlan  
CONFIG_NEUTRON_ML2_MECHANISM_DRIVERS=openvswitch  
CONFIG_NEUTRON_L2_AGENT=openvswitch 
CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=physnet1:br-ex  # 此处的physnet1命名会和稍后的网络配置有关。
CONFIG_NEUTRON_OVS_BRIDGE_IFACES=br-ex:eth0 #将宿主机网卡和openstack服务网卡桥接
CONFIG_PROVISION_DEMO=n  安装演示demo. 不建议,需要连接到github.占用磁盘空间

安装openstack

此过程会比较慢，失败可以重试

packstack --answer-file=/root/test-answer.ini

问题一

ERROR : Failed to run remote script, stdout:stderr: Warning: Permanently added '10.0.1.221' (ECDSA) to the list of known hosts.+ trap t ERR+ facter -pfacter: error while loading shared libraries: leatherman_curl.so.1.3.0: cannot open shared object file: No such file or directory++ t++ exit 127

解决:leatherman版本高，需要降低到1.3.0

 yum downgrade leatherman

问题二

ERROR : Error appeared during Puppet run: 10.0.1.221_controller.ppError: Execution of '/usr/bin/yum -d 0 -e 0 -y install openstack-keystone' returned 1: Error: Package: python2-qpid-proton-0.26.0-2.el7.x86_64 (openstack-train)You will find full trace in log /var/tmp/packstack/20211217-144811-4zhqhW/manifests/10.0.1.221_controller.pp.log

解决：python2-qpid-proton-0.26.0-2.el7.x86_64 这个rpm包找不到合适的。在阿里开源社区下载

wget https://mirrors.aliyun.com/centos/7.9.2009/opstools/x86_64/perfmon/python2-qpid-proton-0.26.0-2.el7.x86_64.rpm
yum -y localinstall python2-qpid-proton-0.26.0-2.el7.x86_64.rpm

问题三

ERROR : Error appeared during Puppet run: 192.168.3.68_controller.pp
Error: Systemd start for httpd failed!
You will find full trace in log /var/tmp/packstack/20240131-095747-Td_9m6/manifests/192.168.3.68_controller.pp.log

selinux或者防火墙没关闭导致

systemctl stop firewalld
setenforce 0

查看，出现successfully则表示安装成功

**** Installation completed successfully ******

 * File /root/keystonerc_admin has been created on OpenStack client host 192.168.3.68. To use the command line tools you need to source the file.
 * To access the OpenStack Dashboard browse to http://192.168.3.68/dashboard .
Please, find your login credentials stored in the keystonerc_admin in your home directory.
 * The installation log file is available at: /var/tmp/packstack/20240131-101339-N0U1GR/openstack-setup.log

3.网络以及镜像配置

命令行操作需要权限

source keystonerc_admin

下载cirros-0.5.0-x86_64-disk.img测试镜像。并上传至contorller节点。

下载地址: http://download.cirros-cloud.net/

cirros镜像是一个小的测试镜像。用于测试openstack部署。

wget https://download.cirros-cloud.net/0.3.0/cirros-0.3.0-x86_64-disk.img  --no-check-certificate

可以通过Dashboard上传或者上传到服务器后采用命令行加载

openstack image create cirros-0.3.0-x86_64-disk  --file /root/images/cirros-0.3.0-x86_64-disk.img  --disk-format qcow2 --container-format bare --public
