搭建多OpenStack多節(jié)點私有云平臺（一）（環(huán)境搭建）

1、 OpenStack搭建多 OpenStack多節(jié)點私有云平臺（）、規(guī)劃虛擬機地址主機名 內(nèi)存 磁盤 途ens33: 41 1controller 4G 20G 控制節(jié)點ens33: 43 1compute14G 20G 計算節(jié)點ens33: 44 1block11G 40G 存儲節(jié)點準備實驗環(huán)境、配置基礎(chǔ)環(huán)境創(chuàng)建第臺主機，安裝完centos7后，再克隆2臺，之后把臺機改成1g內(nèi)存40g磁盤1. 改IP地址修改IP地址：vi /etc/sysconfig/network-scripts/ifcfg-ens33BOOTPROTO=staticIPADDR=41 后2臺機就改這就了NETMASK=

2、GATEWAY=DNS1=14重啟絡(luò)：systemctl restart network2. 改主機名controller：hostnamectl set-hostname controllercompute1：hostnamectl set-hostname compute1block1：hostnamectl set-hostname block13. host解析rootcontroller # vi /etc/hosts localhost localhost.localdomain localhost4 localhost4.localdomain4 controller:1 loc

3、alhost localhost.localdomain localhost6 localhost6.localdomain6 controller41 controller controller.locallocaldomain43 compute1 compute1.locallocaldomain44 block1 block1.locallocaldomainrootcontroller # scp -rp /etc/hosts 43:/etc/hostsrootcontroller # scp -rp /etc/hosts 44:/etc/hosts查看修改結(jié)果rootcontrol

4、ler # cat /etc/hosts4. 連通外rootcontroller # ping -c 10 、配置yum源（可以本地、可以絡(luò)）rootcontroller # yum -y install wgetmv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backupcd /etc/yum.repos.dwget/.help/CentOS7-Base-163.repomv CentOS7-Base-163.repo CentOS-Base.repoyum clean allyum makecac

5、he查看yum有沒有安裝完# yum repolist all、配置SSH免密碼認證每臺主機都要弄ssh-keygen -t rsassh-copy-id -i controllerssh-copy-id -i compute1ssh-copy-id -i block1、關(guān)閉SeLinux和Firewalldsystemctl stop firewalld.servicesystemctl disable firewalld.servicevi /etc/selinux/config修改 SELINUX=disabled、配置時間同步controller安裝chrony組件yum instal

6、l chrony -y添加阿云時間源服務(wù)器vim /etc/chrony.confserver ntp6.aliyuncom iburstallow /24 記得把allow前的#號刪除systemctl enable chronyd.servicesystemctl restart chronyd.servicechronyc sources另外2臺機操作樣yum install chrony -yvim /etc/chrony.confserver controller iburstsystemctl enable chronyd.servicesystemctl restart chro

7、nyd.servicechronyc sources如果虛擬機轉(zhuǎn)到快照，要重新輸以下代碼，或者關(guān)機創(chuàng)建快照systemctl enable chronyd.servicesystemctl restart chronyd.servicechronyc sources、安裝OPenStack客戶端和 OpenStack-selinux。查看yum有沒有 openstackyum list|grep openstack安裝queens版本yum install centos-release-openstack-queens.noarch -y安裝OpenStack-selinux。yum inst

8、all python-openstackclient openstack-selinux -y、安裝及配置 mysql數(shù)據(jù)庫后都是 節(jié)點的操作安裝MariaDB數(shù)據(jù)庫yum install mariadb mariadb-server python2-PyMySQL -y添加mysql配置件vi /etc/f.d/fmysqldbind-address = 41default-storage-engine = innodbinnodb_file_per_tablemax_connections = 4096collation-server = utf8_general_cicharacter-

9、set-server = utf8啟動MariaDB服務(wù)，并設(shè)置其開機啟動，如果這出錯肯是安裝出錯重新安裝下systemctl enable mariadb.servicesystemctl start mariadb.service執(zhí)MariaDB的安全配置腳本執(zhí)安全初始化，在設(shè)置密碼時候官檔的坑不執(zhí)同步數(shù)據(jù)庫出錯)mysql_secure_installationEnter current password for root (enter for none): 車需要輸你當前戶的密碼，默認密碼為空Set root password? Y/n 設(shè)置密碼, 不設(shè)置密碼為空，y可以重新設(shè)置密碼，

10、設(shè)置密碼rootRemove anonymous users? Y/n 移除匿名戶Disallow root login remotely? Y/n 禁遠程登錄Remove test database and access to it? Y/n 移除數(shù)據(jù)庫和訪問它的權(quán)限Reload privilege tables now? Y/n y重載權(quán)限表、NoSQL數(shù)據(jù)庫安裝安裝MongoDB包，于監(jiān)控計費私有云不需要監(jiān)控計費，略過、RabbitMQ安裝及配置 開發(fā)的，運維安裝可運 )1. 安裝包：# yum install rabbitmq-server2. 啟動消息隊列服務(wù)并將其配置為隨系統(tǒng)啟動：

11、# systemctl enable rabbitmq-server.service# systemctl start rabbitmq-server.service3. 添加戶：openstack# rabbitmqctl add_user openstack RABBIT_PASSCreating user openstack .done.合適的密碼替換。RABBIT_DBPASS4. 給openstack戶配置寫和讀權(quán)限：d# rabbitmqctl set_permissions openstack .* .* .*Setting permissions for user openstack in vhost / .done.5. 輸這個代碼進頁rabbitmq-plugins enable rabbitmq_management默認密碼：guest guest（queues 隊列監(jiān)控指標，例如：秒殺、Memcached安裝安裝軟件包：# yum install memcached python-memcached修改配置
