照著官網來安裝openstack pike之environment設置

secure 修改配置 cti es2017 http mysqld and shang miss 
安裝openstack前的準備環境：
兩個centos7系統的環境：192.168.101.10 node1，192.168.101.11 node2
控制節點node1，計算節點node2
1、統一hosts文件：
[root@node1 ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.101.10 node1 192.168.101.11 node2
[root@node2 ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.101.10 node1 192.168.101.11 node2
2、時間同步（控制節點操作）
yum install chrony
修改vim /etc/chrony.conf
allow 192.168.101.0/16 開啟
最後開啟服務：
systemctl enable chronyd.service systemctl start chronyd.service
以下是計算節點或者其他節點操作：
yum install chrony
修改vim /etc/chrony.conf
allow 192.168.101.0/16 開啟
註釋掉：
#server 0.centos.pool.ntp.org iburst #server 1.centos.pool.ntp.org iburst #server 2.centos.pool.ntp.org iburst #server 3.centos.pool.ntp.org iburst server 192.168.101.10 iburst （新增控制節點）
最後開啟服務：
systemctl enable chronyd.service systemctl start chronyd.service
有必要的化請設置時區：timedatectl set-timezone Asia/Shanghai
官網設置：
https://docs.openstack.org/install-guide/environment-ntp-controller.html https://docs.openstack.org/install-guide/environment-ntp-other.html 校驗結果：
3、在所有節點（這裏只有控制節點和計算節點，如果有其他節點也需要操作）操作如下：
yum install centos-release-openstack-pike yum upgrade
If the upgrade process includes a new kernel, reboot your host to activate it.
由於更新了kernel，於是需要進行重啟，以新內核啟動，開啟後，繼續執行：
yum install python-openstackclient yum install openstack-selinux 4、安裝數據庫（在控制節點上） https://docs.openstack.org/install-guide/environment-sql-database-rdo.html# yum install mariadb mariadb-server python2-PyMySQL # vim /etc/my.cnf.d/openstack.cnf
[mysqld]
bind-address = 192.168.101.10
default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8
# systemctl enable mariadb.service
# systemctl start mariadb.service
# mysql_secure_installation
5、安裝消息隊列服務rabbitmq（控制節點上操作）
# yum install rabbitmq-server # systemctl enable rabbitmq-server.service # systemctl start rabbitmq-server.service Add the openstack user: # rabbitmqctl add_user openstack openstack（賬號和密碼） Permit configuration, write, and read access for the openstack user: # rabbitmqctl set_permissions openstack ".*" ".*" ".*"
rabbitmq服務監聽在5672、25672端口
列出rabbitmq的插件：# rabbitmq-plugins list
啟動某一個插件：
# rabbitmq-plugins enable rabbitmq_management
重啟rabbitmq服務：
systemctl restart rabbitmq-server.service
上面這個開啟的插件是一個web管理平臺，監聽在15672端口：
tcp 0 0 0.0.0.0:15672 0.0.0.0:* LISTEN 12581/beam.smp
訪問這個web管理平臺：
http://192.168.101.10:15672 默認賬號密碼：guest：guest 設置使用openstack賬號登錄：
# yum install memcached python-memcached
修改配置文件：/etc/sysconfig/memcached
OPTIONS="-l 127.0.0.1,::1,192.168.101.10"
開啟memcached服務：
# systemctl enable memcached.service # systemctl start memcached.service tcp 0 0 192.168.101.10:11211 0.0.0.0:* LISTEN 12982/memcached tcp 0 0 127.0.0.1:11211 0.0.0.0:* LISTEN 12982/memcached
至此openstack基本前提環境安裝完成
