Openstack 环境准备篇

一、环境准备
1.配置controller节点
1）修改hostname
hostnamectlset-hostname controller
2）配置网络
vi /etc/sysconfig/network-scripts/ifcfg-eth0
TYPE=Ethernet
BOOTPROTO=static
DEFROUTE=no
NAME=eth0
DEVICE=eth0
ONBOOT=yes
IPADDR=10.0.0.11
NETMASK=255.255.255.0
vi /etc/sysconfig/network-scripts/ifcfg-eth1
TYPE=Ethernet
BOOTPROTO=none
NAME=eth1
DEVICE=eth1
ONBOOT=yes
3）配置hosts解析
vi/etc/hosts
10.0.0.11   controller
10.0.0.31   compute1
10.0.0.41   block1
10.0.0.51         object1
10.0.0.52         object2
:wq
reboot
2.配置compute节点
1）修改hostname
hostnamectl set-hostname compute1
2）配置网络
vi /etc/sysconfig/network-scripts/ifcfg-eth0
TYPE=Ethernet
BOOTPROTO=static
DEFROUTE=no
NAME=eth0
DEVICE=eth0
ONBOOT=yes
IPADDR=10.0.0.31
NETMASK=255.255.255.0
:wq
vi /etc/sysconfig/network-scripts/ifcfg-eth1
TYPE=Ethernet
BOOTPROTO=none
NAME=eth1
DEVICE=eth1
ONBOOT=yes
:wq
3)配置hosts解析
scp root@10.0.0.11:/etc/hosts /etc
reboot
剩下节点操作同上，配置完成之后ping通各个节点
3.安装时间服务器
1）安装控制节点
yum -y install chrony
vi /etc/chrony.conf
　　server controller iburst
　　server compute1 iburst
　　server block1 iburst
　　server object1 iburst
　　server object2 iburst
:wq
systemctl enable chronyd.service
systemctl start chronyd.service
2）安装compute节点
yum -y install chrony
vi /etc/chrony.conf
　　server controller iburst
systemctl enable chronyd.service
systemctl start chronyd.service
其他节点同compute节点相同
3）验证，在控制节点执行下面命令
chronyc sources
4.配置openstack软件安装源，我这里用的是centos7
yum install centos-release-openstack-mitaka
yum upgrade
在所有节点执行上面两步操作，重启服务器
1）安装openstack client
yum install python-openstackclient
yum install openstack-selinux
5.安装配置数据库服务
1）安装软件包
yum install mariadb mariadb-server python2-PyMySQL
2）创建并编辑/etc/my.cnf.d/openstack.cnf
vi /etc/my.cnf.d/openstack.cnf
　　[mysqld]
　　bind-address = 10.0.0.11
　　default-storage-engine = innodb
　　innodb_file_per_table
　　max_connections = 4096
　　collation-server = utf8_general_ci
　　character-set-server = utf8
3）启动服务，并加入开机启动
systemctl enable mariadb.service
systemctl start mariadb.service
4）数据库安全设置，配置数据密码，其他全部yes
mysql_secure_installation
6.安装nosql数据库
1）安装MongDB包
yum install mongodb-server mongodb
2）编辑文件/etc/mongod.conf
vi /etc/mongod.conf
　　bind_ip = 10.0.0.11
　　smallfiles = true
3）启动服务，并加入开机启动
　　systemctl enable mongod.service
　　systemctl start mongod.service
7.安装消息队列服务
1）安装包
yum install rabbitmq-server
2）启动消息队列服务并将其配置为随系统启动
　　systemctl enable rabbitmq-server.service
　　systemctl start rabbitmq-server.service
3）添加openstack用户
rabbitmqctl add_user openstack 123123
4）给openstack用户配置和读写权限
rabbitmqctl set_permissions openstack “.*”“.*” “.*”
8.安装Memcached
1）安装软件包
yum install memcached python-memcached
2）启动服务，并加入开机启动
　　systemctl enable memcached.service
　　systemctl start memcached.service
