openstackM版本安装

部署期间常见问题：http://www.cnblogs.com/bfmq/p/6001233.html，问题跟对架构的理解永远比部署重要！你玩技术是绝对是要基于理论的

一.基本情况：
物理设备：4台惠普dl360，4个千兆网卡（用不了4个）
操作系统统一为：CentOS 7.2.1511
Openstack情况：mitaka版本vxlan模式，一台控制节点一台网络节点两台计算节点
网络情况：
管理网络（一般也就是ssh的ip）：60.34.30.0/24
数据网络：60.34.31.0/24

二.环境准备：
1.对所有机器进行解析，添加对应解析，管理网络ip（数据网络ip不需要加）（所有机器）
vim /etc/hosts新增（这也是此次本人安装的ip分布方式）
60.34.30.11 controller01
60.34.30.12 network01
60.34.30.13 computer01
60.34.30.14 computer02
2.关闭防火墙以及selinux（所有机器）
systemctl stop firewalld
chkconfig firewalld off
setenforce 0
iptables -F
vim /etc/selinux/config修改
SELINUX=disabled
3.配置yum源（你存放mitaka相关rpm包的路径）（所有机器，http://www.cnblogs.com/bfmq/p/6027202.html）
vim /etc/yum.repos.d/mitaka.repo创建
[mitaka]
name=mitaka repo
baseurl=file:///root/mitaka/
enabled=1
gpgcheck=0

sed -i s/gpgchek=1/gpgchek=0/g /etc/yum.repos.d/*
yum clean all
yum makecache
yum groupinstall base -y
4.时间服务部署（所有机器）
yum install chrony -y
vim /etc/chrony.conf修改
原有的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全部注释掉
控制节点:
添加server 127.0.0.1 iburst
allow 60.34.30.0/24（管理网段ip/24）

systemctl start chronyd
systemctl enable chronyd
其余节点：
添加server 60.34.30.11 iburst（控制节点管理ip）

systemctl start chronyd
systemctl enable chronyd
chronyc sources

三.正式开始安装
在所有节点执行
yum upgrade
yum install python-openstackclient -y
yum install openstack-selinux -y

1.控制节点
yum install mariadb mariadb-server python2-PyMySQL rabbitmq-server openstack-nova-api openstack-nova-conductor openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler memcached openstack-glance python-memcached openstack-keystone httpd mod_wsgi openstack-dashboard -y

vim /etc/my.cnf.d/openstack.cnf新建内容
[mysqld]
bind-address = 60.34.30.11（控制节点管理网络ip）
default-storage-engine = innodb
innodb_file_per_table
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8

systemctl enable mariadb.service
systemctl start mariadb.service
systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service
rabbitmqctl add_user rabbitmq bfmq
rabbitmqctl set_permissions rabbitmq ".*" ".*" ".*"
systemctl enable memcached.service
systemctl start memcached.service
mysql_secure_installation（设置你的数据库root密码）

mysql -uroot -pbfmq
