OpenStack、keystone组件

g87616758

　　一、部署OpenStack

　　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.

                        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

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　　

　　5、keystone客户端使用

  --os-endpoint <service-endpoint>

                        new token and replace the existing one in the keyring.
  --stale-duration <seconds>
                        Stale duration (in seconds) used to determine whether
                        a token has expired when retrieving it from keyring.
                        This is useful in mitigating process or network
                        delays. Default is 30 seconds.
