openstack之基础环境准备（L版）

圣凤凌霜

　　centos7.1   openstack L版本，环境规划如下
[root@controller ~]# ansible web -a 'hostname'
172.16.80.131 | SUCCESS | rc=0 >>
computer1
172.16.80.130 | SUCCESS | rc=0 >>
controller
[root@controller ~]# ansible web -a 'cat /etc/hosts'
172.16.80.131 | SUCCESS | rc=0 >>
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
172.16.80.130 controller
172.16.80.131 computer1
172.16.80.130 | SUCCESS | rc=0 >>
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
172.16.80.130 controller
172.16.80.131 computer1　　

　　1、配置时间同步

　　[root@controller ~]# ansible web -a 'yum install chrony -y'
　　

　　在controller上面修改
　　[root@controller ~]# vim /etc/chrony.conf
　　allow 172.16.80.0/24
　　

　　[root@controller ~]# systemctl enable chronyd.service
　　[root@controller ~]# systemctl start chronyd.service
　　[root@controller ~]# ansible web -a 'date'
　　172.16.80.130 | SUCCESS | rc=0 >>
　　Sat Oct 29 21:31:36 CST 2016
　　

　　172.16.80.131 | SUCCESS | rc=0 >>
　　Sat Oct 29 21:31:36 CST 2016
　　

　　[root@controller ~]# ansible web -a 'timedatectl set-timezone Asia/Shanghai' 设置时区
　　

　　2、安装openstack源
　　[root@controller ~]# yum install centos-release-openstack-liberty -y
　　[root@controller ~]# yum install https://rdoproject.org/repos/openstack-liberty/rdo-release-liberty.rpm -y
　　

　　3、安装数据库并配置
　　[root@controller ~]# yum install mariadb mariadb-server MySQL-python -y
　　[root@controller ~]# vim /etc/my.cnf
　　[mysqld]
　　default-storage-engine = innodb
　　innodb_file_per_table
　　collation-server = utf8_general_ci
　　init-connect = 'SET NAMES utf8'
　　character-set-server = utf8
　　

　　[root@controller ~]# systemctl enable mariadb.service
　　Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.
　　[root@controller ~]# systemctl start mariadb.service
　　

　　4、创建数据库及授权

MariaDB [(none)]> CREATE DATABASE keystone;
Query OK, 1 row affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY 'keystone';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY 'keystone';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> CREATE DATABASE glance;
Query OK, 1 row affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY 'glance';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY 'glance';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> CREATE DATABASE nova;
Query OK, 1 row affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'nova';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'nova';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> CREATE DATABASE neutron;
Query OK, 1 row affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' IDENTIFIED BY 'neutron';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' IDENTIFIED BY 'neutron';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> CREATE DATABASE cinder;
Query OK, 1 row affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'cinder';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'cinder';
Query OK, 0 rows affected (0.00 sec)　　

　　5、安装消息队列，添加用户授权
　　[root@controller ~]# yum install rabbitmq-server -y
　　

　　[root@controller ~]# systemctl enable rabbitmq-server.service
　　Created symlink from /etc/systemd/system/multi-user.target.wants/rabbitmq-server.service to /usr/lib/systemd/system/rabbitmq-server.service.
　　[root@controller ~]# systemctl start rabbitmq-server.service
　　[root@controller ~]# rabbitmqctl add_user openstack openstack
　　Creating user "openstack" ...

　　[root@controller ~]# rabbitmqctl set_permissions openstack ".*" ".*" ".*"
　　Setting permissions for user "openstack" in vhost "/" ...
　　

　　[root@controller ~]# rabbitmq-plugins list
　　Configured: E = explicitly enabled; e = implicitly enabled
