創建虛擬機
controller部署
computer網絡配置
OpenStack環境准備
controller節點和cpmputer節點執行相同過程
關閉/禁用firewalld
[root@controller ~]# systemctl stop firewalld [root@controller ~]# systemctl disable firewalld Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service. Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
關閉/禁用NetworkManager
[root@controller ~]# systemctl stop NetworkManager [root@controller ~]# systemctl disable NetworkManager Removed symlink /etc/systemd/system/multi-user.target.wants/NetworkManager.service. Removed symlink /etc/systemd/system/dbus-org.freedesktop.NetworkManager.service. Removed symlink /etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service.
禁用SELINUX
[root@controller ~]# cat /etc/selinux/config # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. SELINUX=disable # SELINUXTYPE= can take one of three two values: # targeted - Targeted processes are protected, # minimum - Modification of targeted policy. Only selected processes are protected. # mls - Multi Level Security protection. SELINUXTYPE=targeted
修改hosts
[root@controller ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.80.10 controller controller.cac.com 192.168.80.20 computer computer.cac.com
創建本地yum源
[root@controller yum.repos.d]# cat openstack.repo [openstack] name=openstack enable=1 gpgcheck=0 baseurl=file:///openstack
OpenStack自動化部署
首先安裝自動化軟件openstack-packstack，利用openstack-packstack生成應答文件，修改應答文件，再依據應答文件進行安裝
yum search centos
yum -y install centos-release-openstack-newton
安裝完畢后，會在/etc/yum.repos.d/又生成幾個repo文件，我們安裝不需要聯網，將新生成的repo移入bak
[root@controller yum.repos.d]# ls bak CentOS-Ceph-Jewel.repo CentOS-OpenStack-newton.repo CentOS-QEMU-EV.repo openstack.repo [root@controller yum.repos.d]# mv C* bak/ [root@controller yum.repos.d]# ls bak openstack.repo
安裝openstack-packstack
yum -y install openstack-packstack
生成應答文件(只在controller節點執行)
[root@controller yum.repos.d]# packstack --gen-answer-file=openstack.txt Packstack changed given value to required value /root/.ssh/id_rsa.pub
修改應答文件
首先修改如下選項
CONFIG_DEFAULT_PASSWORD=111111 CONFIG_SWIFT_INSTALL=n CONFIG_NAGIOS_INSTALL=n CONFIG_COMPUTE_HOSTS=192.168.80.20 CONFIG_NETWORK_HOSTS=192.168.80.20 CONFIG_CINDER_VOLUMES_SIZE=1G CONFIG_PROVISION_DEMO=n CONFIG_LBAAS_INSTALL=y CONFIG_NEUTRON_FWAAS=y CONFIG_NEUTRON_VPNAAS=y
執行grep -vE "^#|^$" openstack.txt發現有很多密碼設置，修改密碼為111111。
sed -i -r 's/(.+_PW)=.+/\1=111111/' openstack.txt
依據應答文件進行安裝
packstack --answer-file=openstack.txt
安裝過程中報錯
failure: repodata/repomd.xml from centos-ceph-jewel: [Errno 256] No more mirrors to try. http://mirror.centos.org/centos/7/storage/x86_64/ceph-jewel/repodata/repomd.xml: [Errno 14] curl#6 - "Could not resolve host: mirror.centos.org; Unknown error" ++ t ++ exit 1 Please check log file /var/tmp/packstack/20181003-012303-VTSG5d/openstack-setup.log for more information Additional information: * Time synchronization installation was skipped. Please note that unsynchronized time on server instances might be problem for some OpenStack components.
原因：再computer節點上/etc/yum.repos.d目錄下有生產了新的repo文件，將repo移入bak目錄，再次安裝
安裝過程大約20min
tail -f /var/log/messages可以查看安裝日志
查看是否安裝rabbitmq
rpm -qa | grep rabbitmq-server
查看rabbitmq狀態
systemctl status rabbitmq-server
啟用rabbitmq管理服務
rabbitmq-plugins list
rabbitmq-plugins enable rabbitmq_management
檢查是否啟動成功
netstat -antlp | grep 15672
安裝完成
