照着官网来安装openstack pike之environment设置
安装openstack前的准备环境:
两个centos7系统的环境:192.168.101.10 node1,192.168.101.11 node2
控制节点node1,计算节点node2
1、统一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、时间同步(控制节点操作)
yum install chrony
修改vim /etc/chrony.conf
allow 192.168.101.0/16 开启
最后开启服务:
systemctl enable chronyd.service systemctl start chronyd.service
以下是计算节点或者其他节点操作:
yum install chrony
修改vim /etc/chrony.conf
allow 192.168.101.0/16 开启
注释掉:
#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 (新增控制节点)
最后开启服务:
systemctl enable chronyd.service systemctl start chronyd.service
有必要的化请设置时区:timedatectl set-timezone Asia/Shanghai
官网设置:
校验结果:
3、在所有节点(这里只有控制节点和计算节点,如果有其他节点也需要操作)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.
由于更新了kernel,于是需要进行重启,以新内核启动,开启后,继续执行:
yum install python-openstackclient
yum install openstack-selinux
4、安装数据库(在控制节点上)
# 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、安装消息队列服务rabbitmq(控制节点上操作)
# yum install rabbitmq-server # systemctl enable rabbitmq-server.service # systemctl start rabbitmq-server.service Add the openstack user: # rabbitmqctl add_user openstack openstack(账号和密码) Permit configuration, write, and read access for the openstack user: # rabbitmqctl set_permissions openstack ".*" ".*" ".*"
rabbitmq服务监听在5672、25672端口
列出rabbitmq的插件:
# rabbitmq-plugins list
启动某一个插件:
# rabbitmq-plugins enable rabbitmq_management
重启rabbitmq服务:
systemctl restart rabbitmq-server.service
上面这个开启的插件是一个web管理平台,监听在15672端口:
tcp 0 0 0.0.0.0:15672 0.0.0.0:* LISTEN 12581/beam.smp
访问这个web管理平台:
http://192.168.101.10:15672 默认账号密码:guest:guest
设置使用openstack账号登录:
设置完成,退出登录,使用openstack:openstack登录,即可成功
6、安装memcached服务(控制节点):uses Memcached to cache tokens
# 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"
开启memcached服务:
# 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基本前提环境安装完成
