OpenStack部署
OpenStack环境部署
设备准备
三台CentOS，内存8G，双网卡
控制节点ct：设置网卡
ens33(NAT网卡):
BOOTPROTO=static
IPV4_ROUTE_METRIC=90 #添加调由优先级，有2条默认，使NAT优先，
ONBOOT=yes
IPADDR=192.168.118.44
NETMASK=255.255.255.0
GATEWAY=192.168.118.2
ens36(内网)：
BOOTPROTO=static
ONBOOT=yes
IPADDR=192.168.140.10
NETMASK=255.255.255.0
#GATEWAY=192.168.140.2 #注释网卡
计算节点ct1：
ens33(NAT网卡):
BOOTPROTO=static
IPV4_ROUTE_METRIC=90 #添加调由优先级，有2条默认，使NAT优先，
ONBOOT=yes
IPADDR=192.168.118.55
NETMASK=255.255.255.0
GATEWAY=192.168.118.2
ens36(内网)：
BOOTPROTO=static
ONBOOT=yes
IPADDR=192.168.140.20
NETMASK=255.255.255.0
#GATEWAY=192.168.140.2
计算节点ct2
ens33(NAT网卡):
BOOTPROTO=static
IPV4_ROUTE_METRIC=90 #添加调由优先级，有2条默认，使NAT优先，
ONBOOT=yes
IPADDR=192.168.118.66
NETMASK=255.255.255.0
GATEWAY=192.168.118.2
ens34(内网)：
BOOTPROTO=static
ONBOOT=yes
IPADDR=192.168.140.30
NETMASK=255.255.255.0
#GATEWAY=192.168.140.2
部署OpenStack依赖环境
三个节点同时设置，这里只显示ct节点
[root@ct ~]# vi /etc/hosts
192.168.140.10 ct
192.168.140.20 ct1
192.168.140.30 ct2
[root@ct ~]# ssh-keygen -t rsa #免交互
[root@ct ~]# ssh-copy-id ct
[root@ct ~]# ssh-copy-id ct1
[root@ct ~]# ssh-copy-id ct2
[root@ct ~]# vi /etc/yum.conf #配置YUM能保存下载的安装软件
keepcache=1
##下载安装依赖包
[root@ct ~]# yum -y install net-tools bash-completion vim gcc gcc-c++ make pcre pcre-devel expat-devel cmake bzip2 lrzsz
##EXPAT C语言发开库，这里最好多安装几次
[root@ct ~]# yum -y install centos-release-openstack-train python-openstackclient openstack-selinux openstack-utils
- 设置时间同步
[root@ct ~]# yum install chrony -y
[root@ct ~]# vim /etc/chrony.conf
ct节点：
ct1-2节点
[root@ct ~]# systemctl enable chronyd.service
[root@ct ~]# systemctl restart chronyd.service #三个节点都开启时间同步
[root@ct ~]# crontab -e #配置计划任务，两分钟同步一次
控制节点配置MariaDB
- 安装、配置mariadb
[root@ct ~]# yum -y install mariadb mariadb-server python2-Pymysql
#python2-PyMySQL是OpenStack控制端连接MySQL的模块
[root@ct ~]# yum -y install libibverbs #添加MySQL子配置文件
[root@ct ~]# vim /etc/my.cnf.d/openstack.cnf #设置配置文件，添加以下内容
[mysqld]
bind-address = 192.168.140.10 #设置控制节点局域网地址
default-storage-engine = innodb #设置默认存储引擎
innodb_file_per_table = on #每张表独立表空间文件
max_connections = 4096 #最大连接数
collation-server = utf8_general_ci #最大字符集
character-set-server = utf8
[root@ct ~]# systemctl enable mariadb
Created symlink from /etc/systemd/system/mysql.service to /usr/lib/systemd/system/mariadb.service.
Created symlink from /etc/systemd/system/mysqld.service to /usr/lib/systemd/system/mariadb.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.
[root@ct ~]# systemctl start mariadb #开启mariadb
[root@ct ~]# cd /etc/my.cnf.d/
[root@ct my.cnf.d]# mysql_secure_installation #执行mariadb安全配置脚本
…………………………
Disallow root login remotely? [Y/n] N #交互过程只有这一步选择n允许root登录
…………………………
部署RabbitMQ
[root@ct my.cnf.d]# yum -y install rabbitmq-server
[root@ct my.cnf.d]# 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@ct my.cnf.d]# systemctl start rabbitmq-server.service
[root@ct my.cnf.d]# rabbitmqctl add_user openstack RABBIT_PASS #创建消息队列用户openstack，给予密码为RABBIT_PASS
Creating user "openstack"
[root@ct my.cnf.d]# rabbitmqctl set_permissions openstack ".*" ".*" ".*"
##配置openstack用户的操作权限（正则，配置读写权限）
Setting permissions for user "openstack" in vhost "/"
[root@ct my.cnf.d]# netstat -antp | grep 5672 #查看rabbitmq默认端口
tcp 0 0 0.0.0.0:25672 0.0.0.0:* LISTEN 40164/beam.smp

Applying plugin configuration to rabbit@localhost... started 6 plugins.
部署memcached
memcached用于存储session信息，服务身份验证机制（keystone）使用memcached来缓冲令牌在登陆openstack的dashboard时，会产生session信息，这些session信息会存放到memcached中
[root@ct my.cnf.d]# yum install -y memcached python-memcached
[root@ct my.cnf.d]# vi /etc/sysconfig/memcached #修改memcached配置文件PORT="11211"
USER="memcached"
MAXCONN="1024"
CACHESIZE="64"
OPTIONS="-l 127.0.0.1,::1，ct"
[root@ct my.cnf.d]# systemctl enable memcached
Created symlink from /etc/systemd/system/multi-user.target.wants/memcached.service to /usr/lib/systemd/system/memcached.service.
[root@ct my.cnf.d]# systemctl start memcached
[root@ct my.cnf.d]# netstat -antp | grep 11211
tcp 0 0 192.168.140.10:11211 0.0.0.0:* LISTEN 42358/memcached
tcp 0 0 127.0.0.1:11211 0.0.0.0:* LISTEN 42358/memcached
tcp6 0 0 ::1:11211 :::* LISTEN 42358/memcached
- 安装etcd(由go语言开发的开源，去中心化的数据库)
[root@ct my.cnf.d]# yum install -y etcd
[root@ct my.cnf.d]# vi /etc/etcd/etcd.conf #修改配置文件
[root@ct my.cnf.d]# systemctl enable etcd.service
[root@ct my.cnf.d]# systemctl start etcd.service
[root@ct my.cnf.d]# netstat -anutp |grep 2379
tcp 0 0 192.168.140.10:2379 0.0.0.0:* LISTEN 45160/etcd

tcp 0 0 192.168.140.10:50826 192.168.140.10:2379 ESTABLISHED 45160/etcd
[root@ct my.cnf.d]# netstat -anutp |grep 2380
tcp 0 0 192.168.140.10:2380 0.0.0.0:* LISTEN 45160/etcd
Keystone组件部署
部署openstack组件需要安装Apache运行认证服务keystone（需要安装），然后安装镜像服务glance，计算服务nova，网络服务neutron
- 创建数据库实例和数据库用户
[root@ct ~]# mysql -uroot -p
MariaDB [(none)]> create database keystone; #创建库
Query OK, 1 row affected (0.001 sec)
##给予权限
MariaDB [(none)]> grant all privileges on keystone.* to 'keystone'@'localhost' identified by 'KEYSTONE_DBPASS';
Query OK, 0 rows affected (0.001 sec)
MariaDB [(none)]> grant all privileges on keystone.* to 'keystone'@'%' identified by 'KEYSTONE_DBPASS';
Query OK, 0 rows affected (0.000 sec)
MariaDB [(none)]> flush privileges; #刷新权限表
Query OK, 0 rows affected (0.001 sec)
MariaDB [(none)]> exit

- 安装配置keystone、httpd、mod_wsgi（用来让apache能够代理python程序的组件）
[root@ct ~]# yum install -y openstack-keystone httpd mod_wsgi
[root@ct ~]# cp -a /etc/keystone/keystone.conf,.bak
[root@ct ~]# grep -Ev "^$|#" /etc/keystone/keystone.conf.bak > /etc/keystone/keystone.conf
#过滤空格或#开头内容，并将内容覆盖到配置文件中

##知道token的提供者为keystone自身
[root@ct ~]# openstack-config --set /etc/keystone/keystone.conf token provider fernet
##初始化认证服务数据库
[root@ct ~]# su -s /bin/sh -c "keystone-manage db_sync" keystone
##初始fernet密钥存储库，生成两个密钥，生成的密钥放于/etc/keystone/目录下，用于加密数据
[root@ct ~]# keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
[root@ct ~]# keystone-manage credential_setup --keystone-user keystone --keystone-group keystone
