7：一步一步部署一个openstack集群

7.1 openstack基础架构

7.1：准备环境

注意：主机之间相互host解析

7.1.1 时间同步

#服务端，controller节点 
vim /etc/chrony.conf 
allow 10.0.0.0/24 
systemctl restart chronyd 
#客户端，compute1节点 
vim /etc/chrony.conf 
server 10.0.0.11 iburst 
systemctl restart chronyd
验证：同时执行date

7.1.2：配置yum源，并安装客户端

#所有节点 
#配置过程： 
cd /opt/ 
rz -E 
tar xf openstack_ocata_rpm.tar.gz 
cd /etc/yum.repos.d/ 
mv *.repo /tmp 
mv /tmp/CentOS-Base.repo . 
vi openstack.repo 
[openstack] 
name=openstack 
baseurl=file:///opt/repo 
enable=1 
gpgcheck=0 
#验证： 
yum clean all yum install python-openstackclient -y

7.1.3：安装数据库

#控制节点 
yum install mariadb mariadb-server python2-PyMySQL -y 
##openstack所有组件使用python开发，openstack在连接数据库需要用到python2-PyMySQL模块 
#修改mariadb配置文件 
vi /etc/my.cnf.d/openstack.cnf 
[mysqld] 
bind-address = 10.0.0.11 
default-storage-engine = innodb 
innodb_file_per_table = on 
max_connections = 4096 
collation-server = utf8_general_ci 
character-set-server = utf8 
#启动数据库 
systemctl start mariadb 
systemctl enable mariadb 
#数据库安全初始化 
mysql_secure_installation 
回车n
一路y

7.1.3 安装消息队列rabbitmq

#控制节点 
#安装消息队列 
yum install rabbitmq-server 
#启动rabbitmq 
systemctl start rabbitmq-server.service 
systemctl enable rabbitmq-server.service 
#在rabbitmq创建用户 
rabbitmqctl add_user openstack 123456 
#为刚创建的openstack授权 
rabbitmqctl set_permissions openstack ".*" ".*" ".*"

7.1.4 安装memcache缓存

#控制节点 
#安装memcache 
yum install memcached python-memcached -y 
##python-memcached是python连接memcache的模块插件 
#配置 
vim /etc/sysconfig/memcached 
##修改最后一行 
OPTIONS="-l 0.0.0.0" 
#启动服务 
systemctl start memcached 
systemctl enable memcached

7.2 安装keystone服务

#创库授权 
##登录
mysql 
CREATE DATABASE keystone; 
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY '123456'; 
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY '123456';
#安装keystone服务 
yum install openstack-keystone httpd mod_wsgi -y 
##httpd配合mod_wsgi插件调用python项目 
#修改keystone配置文件 
cp /etc/keystone/keystone.conf{,.bak} 
grep -Ev '^$|#' /etc/keystone/keystone.conf.bak >/etc/keystone/keystone.conf
