  • openstack 基础服务软件安装配置(queens,centos-7)

    介绍

    openstack 可以根据使用场景分配多种组合架构,此处以两个节点,控制节点和计算节点为例展示安装配置过程。注意:openstack 中每个节点服务器的主机名必须是唯一且后期不可变更的。(centos-7 配置/etc/hostname和/etc/hosts)

    时间同步

    两个节点都要配置时间同步服务(参照官方文档即可),在openstack 中所有节点时间必须一致,设置控制节点同步时间服务器时间,其他节点同步控制节点的时间。

    基础软件包安装(默认yum 源即可)

    两个节点都要执行

    yum install centos-release-openstack-queens

    yum upgrade                (注意:此命令不仅升级软件包还会升级系统版本和内核版本,生产环境不可使用此命令)

    yum install python-openstackclient

    数据库安装配置(控制节点安装)

    yum install mariadb mariadb-server python2-PyMySQL

    创建和编辑/etc/my.cnf.d/openstack.cnf文件

    创建一个[mysqld]部分,并将bind-address 密钥设置为控制器节点的管理IP地址,以允许其他节点通过管理网络进行访问。设置其他键以启用有用选项和UTF-8字符集:

    [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

    启动数据库服务并将其配置为在系统引导时启动:

    # systemctl enable mariadb.service
    # systemctl start mariadb.service

    数据库安全设置

    mysql_secure_installation  #先回车,再设置密码,往后一律Y 同意即可

    数据库创建并授权:     #以下操作可以在创建各个服务时候再操作,也可以提前操作。

    MariaDB [(none)]> create database keystone;

    MariaDB [(none)]> create database glance;

    MariaDB [(none)]> create database nova;

    MariaDB [(none)]> create database nova_api;

    MariaDB [(none)]> create database neutron;

    MariaDB [(none)]> create database cinder;

    MariaDB [(none)]> grant all on keystone.* to 'keystone'@'localhost' identified by 'keystone';

    MariaDB [(none)]> grant all on keystone.* to 'keystone'@'%' identified by 'keystone';

    MariaDB [(none)]> grant all on glance.* to 'glance'@'localhost' identified by 'glance';

    MariaDB [(none)]> grant all on glance.* to 'glance'@'%' identified by 'glance';

    MariaDB [(none)]> grant all on nova.* to 'nova'@'localhost' identified by 'nova';

    MariaDB [(none)]> grant all on nova.* to 'nova'@'%' identified by 'nova';

    MariaDB [(none)]> grant all on nova_api.* to 'nova'@'localhost' identified by 'nova';

    MariaDB [(none)]> grant all on nova_api.* to 'nova'@'%' identified by 'nova';

    MariaDB [(none)]> grant all on neutron.* to 'neutron'@'localhost' identified by 'neutron';

    MariaDB [(none)]> grant all on neutron.* to 'neutron'@'%' identified by 'neutron';

    MariaDB [(none)]> grant all on cinder.* to 'cinder'@'localhost' identified by 'cinder';

    MariaDB [(none)]> grant all on cinder.* to 'cinder'@'%' identified by 'cinder';


    show databases 查看数据库是否全部创建,名字是否正确

    消息队列服务安装配置

    (此服务可以安装在任意节点,如果规模很大需要单独安装并作集群)

    yum install rabbitmq-server
    systemctl enable rabbitmq-server.service
    systemctl start rabbitmq-server.service

    添加openstack用户:
    # rabbitmqctl add_user 用户名 密码
    允许用户进行配置,写入和读取访问 openstack:
    # rabbitmqctl set_permissions openstack ".*" ".*" ".*"

    rabbitmq-plugins list 查看可用的插件
    rabbitmq-plugins enable rabbitmq_management 启用此插件,就可以web 页面管理rabbitmq 了
    [root@localhost my.cnf.d]# lsof -i:15672 查看是否已经启动
    COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
    beam.smp 36610 rabbitmq 55u IPv4 82209 0t0 TCP *:15672 (LISTEN)
    登录web 页面 http://192.168.1.1:15672/ 注意管理员为guest 密码guest ,可以登录后更改一下密码

    memcache 服务安装配置

    yum install memcached python-memcached

     /etc/sysconfig/memcached 

    PORT="11211"
    USER="memcached"
    MAXCONN="1024"         #最大lianjieshu
    CACHESIZE="64"          #内存64M
    OPTIONS="-l controller,::1"      #监听地址为controller

    systemctl enable memcached.service
    systemctl start memcached.service
