1、环境
OS：CentOS6.5 X86_64
各节点时间同步、能基于主机名通信，清空iptables，关闭SElinux，禁用WorkManager服务
各节点的主机/etc/hosts文件配置:
cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.10.1 Node1 node1 controller www.node1.com 192.168.10.2 Node2 node2 compute www.node2.com 192.168.10.3 Node3 node3 network www.node3.com 192.168.10.4 Node4 node4 www.node4.com
2、配置Controller Node（Node1）的网络
1）所有192.168.10.0段的数据包的源地址改成172.16.11.210
[root@Node1 ~]# iptables -t nat -A POSTROUTING -s 192.168.10.0/24 -j SNAT --to-source 172.16.11.210 [root@Node1 ~]# service iptables save
2）打开内核的路由（网卡间转发）功能
要实现nat，要将文件/proc/sys/net/ipv4/ip_forward内的值改为1，（默认是0）
[root@Node1 ~]# vi /etc/sysctl.conf [root@Node1 ~]# sysctl -p net.ipv4.ip_forward = 1 net.ipv4.conf.default.rp_filter = 1 net.ipv4.conf.default.accept_source_route = 0 kernel.sysrq = 0 kernel.core_uses_pid = 1 net.ipv4.tcp_syncookies = 1 error: "net.bridge.bridge-nf-call-ip6tables" is an unknown key error: "net.bridge.bridge-nf-call-iptables" is an unknown key error: "net.bridge.bridge-nf-call-arptables" is an unknown key kernel.msgmnb = 65536 kernel.msgmax = 65536 kernel.shmmax = 68719476736 kernel.shmall = 4294967296
3）配置yum源
[root@Node1 yum.repos.d]# cat CentOS-OpenStack-icehouse.repo # CentOS-OpenStack-icehouse.repo # [centos-openstack-icehouse] name=CentOS-$releasever - OpenStack icehouse baseurl=https://repos.fedorapeople.org/repos/openstack/EOL/openstack-icehouse/epel-6/ #为什么现在这个博客很容易吞链接啊，一没注意链接就发不出来 gpgcheck=0 enabled=1
二、Identity（Keystone）组件
1、Identity主要有两个功能
用户管理：认证和授权
认证方式有两种：
token：持有授权字符串
帐号和密码：
服务目录：所有可用服务的信息库，包含其API endpoint（访问端口）路径
2、常用术语
user：一个user可以关联至多个tenant（租户）
Tenant：租户，一个tenant对应一个project，或一个组织
Role：角色
Token：令牌
Service：服务
Endpoint：服务的访问入口
3、在Controller Node上安装keystone组件
[root@Node1 ~]# yum install openstack-keystone python-keystoneclient [root@Node1 ~]# yum install openstack-utils [root@Node1 yum.repos.d]# rpm -ql openstack-utils /usr/bin/openstack-config /usr/bin/openstack-db /usr/bin/openstack-service /usr/bin/openstack-status /usr/share/doc/openstack-utils-2014.1
4、安装数据库，授权keystone能够远程连入MySQLd，并初始化数据库
1）安装OpenStack优化的Mariabd数据库并初始化
[root@Node1 ~]# yum install mariadb-galera-server -y
修改配置文件/etc/keystone/keystone.conf配置文件:
定义客户端如何连接到keystone服务器
默认配置：
#connection=mysql://keystone:keystone@localhost/keystone
mysql协议 用户名 密码 主机 数据库
授权keystone连接mysqld:
mysql> CREATE DATABASE keystone; mysql> GRANT ALL ON keystone.* TO 'keystone'@'%' IDENTIFIED BY 'keystone'; Query OK, 0 rows affected (0.00 sec) mysql> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY 'KEYSTONE_DBPASS'; mysql> FLUSH PRIVILEGES; Query OK, 0 rows affected (0.00 sec)
keystone-manage初始化数据库：
[root@Node1 ~]# keystone-manage --help
usage: keystone-manage [db_sync|db_version|pki_setup|ssl_setup|token_flush]
optional arguments:
-h, --help show this help message and exit
--config-dir DIR Path to a config directory to pull *.conf files from.
This file set is sorted, so as to provide a
predictable parse order if individual options are
over-ridden. The set is parsed after the file(s)
specified via previous --config-file, arguments hence
over-ridden options in the directory take precedence.
--config-file PATH Path to a config file to use. Multiple config files
can be specified, with values in later files taking
precedence. The default files used are: None
--debug, -d Print debugging output (set logging level to DEBUG
instead of default WARNING level).
--log-config-append PATH, --log_config PATH
The name of logging configuration file. It does not
disable existing loggers, but just appends specified
logging configuration to any other existing logging
options. Please see the Python logging module
documentation for details on logging configuration
files.
--log-date-format DATE_FORMAT
Format string for %(asctime)s in log records. Default:
None
--log-dir LOG_DIR, --logdir LOG_DIR
(Optional) The base directory used for relative --log-
file paths
--log-file PATH, --logfile PATH
(Optional) Name of log file to output to. If no
default is set, logging will go to stdout.
--log-format FORMAT DEPRECATED. A logging.Formatter log message format
string which may use any of the available
logging.LogRecord attributes. This option is
deprecated. Please use logging_context_format_string
and logging_default_format_string instead.
--nodebug The inverse of --debug
--nostandard-threads The inverse of --standard-threads
--nouse-syslog The inverse of --use-syslog
--nouse-syslog-rfc-format
The inverse of --use-syslog-rfc-format
--noverbose The inverse of --verbose
--pydev-debug-host PYDEV_DEBUG_HOST
Host to connect to for remote debugger.
--pydev-debug-port PYDEV_DEBUG_PORT
Port to connect to for remote debugger.
--standard-threads Do not monkey-patch threading system modules.
--syslog-log-facility SYSLOG_LOG_FACILITY
Syslog facility to receive log lines
--use-syslog Use syslog for logging. Existing syslog format is
DEPRECATED during I, and then will be changed in J to
honor RFC5424
--use-syslog-rfc-format
(Optional) Use syslog rfc5424 format for logging. If
enabled, will add APP-NAME (RFC5424) before the MSG
part of the syslog message. The old format without
APP-NAME is deprecated in I, and will be removed in J.
--verbose, -v Print more verbose output (set logging level to INFO
instead of default WARNING level).
--version show program's version number and exit
Commands:
{token_flush,db_version,pki_setup,ssl_setup,db_sync}
Available commands
db_sync Sync the database.
db_version Print the current migration version of the database.
pki_setup Set up Key pairs and certificates for token signing
and verification.
ssl_setup Create key pairs and certificates for HTTPS
connections.
token_flush Flush expired tokens from the backend.# su -s /bin/sh -c "keystone-manage db_sync" keystone mysql> use keystone Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed mysql> show tables; +-----------------------+ | Tables_in_keystone | +-----------------------+ | assignment | | credential | | domain | | endpoint | | group | | migrate_version | | policy | | project | | region | | role | | service | | token | | trust | | trust_role | | user | | user_group_membership | +-----------------------+ 16 rows in set (0.00 sec)
2）编辑/etc/keystone/keystone.conf配置文件
设置token：
[root@Node1 ~]# ADMIN_TOKEN=$(openssl rand -hex 10) #随机设置几个字符串也是可以的 [root@Node1 ~]# echo $ADMIN_TOKEN 8dc775e8139f48a8de39 [root@Node1 ~]# echo $ADMIN_TOKEN > admin_token.rc #保存起来，以便以后用到 [root@Node1 ~]# vi /etc/keystone/keystone.conf #admin_token=ADMIN #找到这行，并复制 admin_token=8dc775e8139f48a8de39 #用字符串代替ADMIN
设置本地PKI:
[root@Node1 ~]# keystone-manage pki_setup --keystone-user keystone --keystone-group keystone [root@Node1 ~]# chown -R keystone:keystone /etc/keystone/ssl [root@Node1 ~]# chmod -R o-rwx /etc/keystone/ssl
启动keystone：
[root@Node1 ~]# service openstack-keystone start Starting keystone: [ OK ] [root@Node1 ~]# chkconfig openstack-keystone on
设置环境变量:
[root@Node1 ~]# export OS_SERVICE_TOKEN=$ADMIN_TOKEN #方便客户端使用 [root@Node1 ~]# export OS_SERVICE_ENDPOINT=http://192.168.10.1:35357/v2.0
