学习openstack（二）

 

 

OpenStack企业私有云实践

1.     实验架构

OpenStack我们把它当作是一个全新的“Linux”系统来学习，有的时候我们也把OpenStack称之为一个新的Linux系统。

l  部分组件介绍：

Ø  RabbitMQè消息队列组件（组件之间的通讯）

Ø  Horizonè提供图形界面的组件

Ø  KeyStoneè各个组件的注册和验证

Ø  Glanceè“镜像”管理组件

Ø  MySQLè存储各个组件的数据

2.     OpenStack插件服务简介

2.1.       Keystone验证服务

ü  用户与认证:用户权限与用户行为跟踪；

ü  服务目录:提供一个服务目录，包括所有服务项与相关Api的端点

2.2.       Glance镜像服务

²  User：用户

²  Tenant：租户

²  Token：令牌

²  Role：角色

²  Service：服务

²  Endpoint：端点

2.3.       Nova计算服务

Ø  API：负责接收和响应外部请求。支持OpenStack API， EC2API。

Ø  Cert：负责身份认证。

Ø  Scheduler：用于云主机调度。

Ø  Conductor：计算节点访问数据的中间件。

Ø  Consoleauth：用于控制台的授权验证。

Ø  Novncproxy： VNC代理。

Nova Dashboard（nova仪表盘）

Ø  提供一个Web界面操作OpenStack的系统。

Ø  使用Django框架基于OpenStack API开发。

Ø  支持将Session存储在DB、 Memcached。

Ø  支持集群。

Nova scheduler

       Nova Scheduler模块在OpenStack中的作用就是决策虚拟机创建在哪个主机（计算节点）上。

       决策一个虚拟机应该调度到某物理节点，需要分两个步骤：

1.       过滤（Fliter）

2.       计算权值（Weight）

3.     基础环境准备（统一操作）

3.1.       更改主机名

计算节点：

 

1
2
3
hostname linux-node1.example.com
vim /etc/sysconfig/network
HOSTNAME=linux-node1.example.com

控制节点：

 

1
2
3
hostname linux-node2.example.com
vim /etc/sysconfig/network
HOSTNAME=linux-node2.example.com

 

3.2.       统一更改hosts文件

 

1
2
3
[root@localhost ~]# tail -2 /etc/hosts
192.168.1.36 linux-node1.example.com linux-node1
192.168.1.37 linux-node2.example.com linux-node2

退出从新登录：

 

1
2
[root@linux-node1 ~]# ping linux-node1
[root@linux-node1 ~]# ping linux-node2

 

3.3.       关闭Selinux与Iptables

 

1
2
3
grep "SELINUX=disabled" /etc/selinux/config
chkconfig iptables off
/etc/init.d/iptables stop

 

3.4.       时间同步

 

1
2
3
4
/usr/sbin/ntpdate time.nist.gov
[root@linux-node1 ~]# crontab -l
#time sync by nick at 2015-3-21
*/5 * * * * /usr/sbin/ntpdate time.nist.gov >/dev/null 2>&1

 

3.5.       安装epel包

1
2
rpm -ivh 
http://mirrors.ustc.edu.cn/fedora/epel//6/x86_64/epel-release-6-8.noarch.rpm

 

4.     安装部署（控制节点操作）

4.1.       安装基础包

1
yum install -y python-pip gcc gcc-c++ make libtool patch automake python-devel libxslt-devel MySQL-python openssl-devel libudev-devel git wget libvirt-python libvirt qemu-kvm gedit python-numdisplay python-eventlet device-mapper bridge-utils libffi-devel libffi

 

4.2.       MySQL安装与配置

4.2.1.      Install MySQL

default-storage-engine = innodb
innodb_file_per_table
collation-server = utf8_general_ci 
init-connect = 'SET NAMES utf8' 
character-set-server = utf8

 

4.2.3.      启动MySQL

[root@linux-node1 ~]#

 

4.4.3.      Config ssl permission

上面创建完成之后，默认会生成“/etc/keystone/ssl/”证书目录及证书文件，此时需要设置目录的权限。

快速执行命令：

 

1
2
chown -R keystone:keystone /etc/keystone/ssl/
chmod -R o-rwx /etc/keystone/ssl/

 

操作过程：

 

1
2
[root@linux-node1 ~]# chown -R keystone:keystone /etc/keystone/ssl/
[root@linux-node1 ~]# chmod -R o-rwx /etc/keystone/ssl/

 

4.4.4.      配置keystone的admin_token

Keystone的所有配置都在一个文件里，即：/etc/keystone/keystone.conf

1)       打开配置文件并编辑：

 

1
2
3
4
vim /etc/keystone/keystone.conf
[root@linux-node1 ~]# egrep -n "^[a-z]" /etc/keystone/keystone.conf 
13:admin_token=ADMIN
619:connection=mysql://keystone:keystone@192.168.1.36/keystone

 

2)       同步数据库

配置keystone之后，需要同步数据库，作用是建立keystone的表结构。

快速执行命令：

 

1
2
keystone-manage db_sync
mysql -h 192.168.1.36 -u keystone -pkeystone -e "use keystone;show tables;"

2
[root@linux-node1 ~]# mysql -h 192.168.1.36 -u keystone -pkeystone -e "use keystone;show tables;"
ERROR 1045 (28000): Access denied for user 'keystone'@'linux-node1.example.com' (using password: YES)

 

如果报以上错误，经过排查后发现是MySQL的keystone用户没有权限所导致，当然上面的数据同步也就不会成功。解决方法可以重新授权keystone用户，如下：

1
grant all on keystone.* to keystone@'192.168.1.0/255.255.255.0' identified by 'keystone';

 

4.4.5.      配置keystone的Debug及日志功能

 

1
2
3
4
vim /etc/keystone/keystone.conf
[root@linux-node1 ~]# egrep -n '^[a-z]' /etc/keystone/keystone.conf
374:debug=true
439:log_file=/var/log/keystone/keystone.log

       打开debug之后，有什么问题都可以查看debug错误日志，以便后面实验排查解决错误。

 

ü  赵班长强心针：OpenStack所有问题，基本上都能解决。而且，看日志都能看出来，当在生产环境下的报错，你第一反应应该是看日志，而不是说先把报错发出来，没有用。

 

4.4.6.      Start Keystone

终于到了启动keystone的环节了，继续ing：

1)       启动：

 

1
2
3
chown -R keystone:keystone /var/log/keystone/*
/etc/init.d/openstack-keystone start
chkconfig openstack-keystone on

 

2)       keystone监听的端口：

 

1
2
3
[root@linux-node1 ~]# netstat -lntup|egrep "35357|5000"
tcp        0      0 0.0.0.0:35357         0.0.0.0:*           LISTEN      24783/python 
tcp        0      0 0.0.0.0:5000          0.0.0.0:*           LISTEN      24783/python

4.5.       Glance安装与配置

n  Glance是OpenStack中的一个镜像服务，主要作用是提供虚拟机的虚拟镜像注册、查询、存储的功能。

n  Glance由三个部分组成，分别为：glance-api、glance-registry以及image store。

4.5.1.      Install Glance

1
yum install openstack-glance python-glanceclient python-crypto

 

4.5.2.      Config Glance

Glance的默认配置路径在“/etc/glance/”目录下：

[root@linux-node1 ~]# cd /etc/glance/
[root@linux-node1 glance]# ls
glance-api.conf    glance-registry.conf  policy.json
glance-cache.conf  glance-scrubber.conf  schema-image.json
#只需要配置标记的两个文件

564:connection=mysql://glance:glance@192.168.1.36/glance
[root@linux-node1 glance]# egrep -n '^[a-z]' glance-registry.conf 
6:debug=true
19:log_file=/var/log/glance/registry.log
94:connection=mysql://glance:glance@192.168.1.36/glance

 

2)       同步数据库

[root@linux-node1 glance]# glance-manage db_sync  ç执行的时候会有5秒左右的延时
/usr/lib64/python2.6/site-packages/Crypto/Util/number.py:57: PowmInsecureWarning: Not using mpz_powm_sec.  You should rebuild using libgmp >= 5 to avoid timing attack vulnerability.
  _warn("Not using mpz_powm_sec.  You should rebuild using libgmp >= 5 to avoid timing attack vulnerability.", PowmInsecureWarning)  ç这个是警告，不过没关系。
[root@linux-node1 glance]#

     到此，“控制节点”部分组件安装及配置部署完毕，接下来对“计算节点”进行配置。

 

4.7.       Nova安装与配置（计算节点操作）

4.7.1.      Nova-Compute 介绍

l  Nova-compute 一般运行在计算节点上，通过Message Queue接管并管理VM的生命周期

l  Nova-compute 通过Libvirt管理KVM，通过XenAPI管理Xen等。

4.7.2.      Install Nova-compute

！！注意！！再次确认，以下步骤将是在“计算节点”上操作！

 

1
2
yum install -y http://repos.fedorapeople.org/repos/openstack/openstack-icehouse/rdo-release-icehouse-4.noarch.rpm
yum install -y qemu-kvm libvirt openstack-nova-compute python-novaclient

 

       查看系统是否支持KVM硬件虚拟化

1
2
[root@linux-node2 ~]# egrep -c '(vmx|svm)' /proc/cpuinfo 
1

 

4.7.3.      Config Nova

1)       控制节点推送配置文件到计算节点

注意：需要到控制节点推送配置文件到计算节点，具体操作如下：

！！在控制节点（node1）节点上推送！！

[root@linux-node1 ~]# scp /etc/nova/nova.conf 192.168.1.37:/etc/nova/
The authenticity of host '192.168.1.37 (192.168.1.37)' can't be established.
RSA key fingerprint is ec:67:00:b2:b9:2e:68:cc:1d:d7:9c:ac:b3:28:ed:24.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '192.168.1.37' (RSA) to the list of known hosts.
root@192.168.1.37's password: 
nova.conf                                                         100%   97KB  96.8KB/s   00:00

 

2)       更改配置

Nova的很多配置都在控制节点上完成了，控制节点把文件推送到计算节点后，只需要更改以下内容即可：

 

1
2
[root@linux-node2 ~]# egrep -n "^[a-z]" /etc/nova/nova.conf
2048:vncserver_proxyclient_address=192.168.1.37 ç改成计算节点的IP地址

 

4.7.4.      Start Nova

[root@linux-node2 ~]# /etc/init.d/libvirtd start
[root@linux-node2 ~]# /etc/init.d/messagebus start
[root@linux-node2 ~]# /etc/init.d/openstack-nova-compute start
[root@linux-node2 ~]# chkconfig openstack-nova-compute on
[root@linux-node2 ~]# chkconfig libvirtd on
[root@linux-node2 ~]# chkconfig messagebus on

 

       在控制节点上查看Nova的配置是否生效
