Openstack-M版部署一基础环境配置

官方文档：https://docs.openstack.org/mitaka/install-guide-rdo/ 注：本次搭建，凡是涉及到密码的，均使用六个零（000000）

一、基础环境配置

1.主机网路（需要能上外网）

1.1虚拟机信息

控制节点： 系统版本：Centos-7.2 1处理器，2GB内存，100G存储（有条件可以给更高的） 主机名：controller 管理IP：10.0.10.130/24 IP2:10.0.20.140/24 计算节点： 系统版本：Centos-7.2 1处理器，4GB内存，100G存储 主机名：compute 管理IP：10.0.10.131/24 IP2:10.0.20.141/24

1.2.配置主机名与解析（控制节点与计算节点）：

控制节点 [root@controller ~]# hostnamectl set-hostname controller && bash [root@controller ~]# vi /etc/hosts 127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6 10.0.10.130 controller 10.0.10.131 compute [root@controller ~]# cat /etc/redhat-release  CentOS Linux release 7.2.1511 (Core)  [root@controller ~]# uname -a Linux controller 3.10.0-327.el7.x86_64 #1 SMP Thu Nov 19 22:10:57 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux 计算节点 [root@compute ~]# hostnamectl set-hostname compute && bash [root@compute ~]# cat /etc/hosts 127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6 10.0.10.130 controller 扫描二维码关注公众号，回复： 1833035 查看本文章 10.0.10.131 comput [root@compute ~]# cat /etc/redhat-release  CentOS Linux release 7.2.1511 (Core)  [root@compute ~]# uname -a Linux compute 3.10.0-327.el7.x86_64 #1 SMP Thu Nov 19 22:10:57 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

1.3.配置yum仓库（这里使用的是centos的官方yum）

控制节点 [root@controller ~]# cat /etc/yum.repos.d/openstack-mitaka.repo  [openstack] name=openstack baseurl=http://vault.centos.org/7.2.1511/cloud/x86_64/openstack-mitaka enabled=1 gpgcheck=0 计算节点 [root@compute ~]# cat /etc/yum.repos.d/openstack-mitaka.repo  [openstack] name=openstack baseurl=http://vault.centos.org/7.2.1511/cloud/x86_64/openstack-mitaka enabled=1 gpgcheck=0

2.安装ntp，配置时间同步

控制节点（安装完，将系统市区改为上海） [root@controller ~]# yum install ntp -y [root@controller ~]# systemctl start ntpd [root@controller ~]# systemctl enable ntpd Created symlink from /etc/systemd/system/multi-user.target.wants/ntpd.service to /usr/lib/systemd/system/ntpd.service. [root@controller ~]# timedatectl set-timezone Asia/Shanghai [root@controller ~]# timedatectl        Local time: Fri 2018-06-29 10:10:40 CST   Universal time: Fri 2018-06-29 02:10:40 UTC         RTC time: Fri 2018-06-29 02:10:39        Time zone: Asia/Shanghai (CST, +0800)      NTP enabled: no NTP synchronized: yes  RTC in local TZ: no       DST active: n/a 计算节点 [root@compute ~]# yum install ntp -y [root@compute ~]# systemctl start ntpd [root@compute ~]# systemctl enable ntpd Created symlink from /etc/systemd/system/multi-user.target.wants/ntpd.service to /usr/lib/systemd/system/ntpd.service. [root@compute ~]# timedatectl set-timezone Asia/Shanghai [root@compute ~]# timedatectl       Local time: Fri 2018-06-29 10:50:06 CST   Universal time: Fri 2018-06-29 02:50:06 UTC         RTC time: Fri 2018-06-29 02:50:06        Time zone: Asia/Shanghai (CST, +0800)      NTP enabled: no NTP synchronized: yes  RTC in local TZ: no       DST active: n/a

3.安装OpenStack插件

控制节点 [root@controller ~]# yum install python-openstackclient -y（安装opentack必须的插件） [root@controller ~]# yum install openstack-selinux -y（默认情况下，RHEL和CentOS启用SELinux，安装 openstack-selinux软件包以自动管理OpenStack服务的安全策略：） 计算节点 [root@compute ~]# yum install python-openstackclient -y [root@compute ~]# yum install openstack-selinux -y

4.SQL数据库安装（控制节点）

4.1安装所需要的包 [root@controller ~]#yum install mariadb mariadb-server python2-PyMySQL -y 4.2创建并编辑/etc/my.cnf.d/openstack.cnf文件并完成以下操作 [root@controller ~]# vim /etc/my.cnf.d/openstack.cnf [mysqld] bind-address = 10.0.10.130#控制节点管理IP default-storage-engine = innodb max_connections = 4096 innodb_file_per_table collation-server = utf8_general_ci character-set-server = utf8 4.3启动，设置开机自启动。 [root@controller ~]# systemctl enable mariadb.service Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service. [root@controller ~]# systemctl start mariadb.service  4.4初始化数据库（我设置000000为密码，之后所有用到密码的地方我都使用000000） [root@controller ~]# mysql_secure_installation

5.NoSQL数据库

5.1安装所需要的包 [root@controller ~]# yum install mongodb-server mongodb -y 5.2编辑配置文件 [root@controller ~]# vim /etc/mongod.conf bind_ip = 10.0.10.130#控制节点管理IP smallfiles = true 5.3启动服务并设置开机自启动 [root@controller ~]# systemctl enable mongod.service Created symlink from /etc/systemd/system/multi-user.target.wants/mongod.service to /usr/lib/systemd/system/mongod.service. [root@controller ~]# systemctl start mongod.service

6.消息队列

6.1安装所需要的包 [root@controller ~]# yum install rabbitmq-server -y 6.2启动服务，开机自启动 [root@controller ~]# 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@controller ~]# systemctl start rabbitmq-server.service  6.3添加openstack用户 [root@controller ~]# rabbitmqctl add_user openstack 000000 Creating user "openstack" ... 6.4允许OpenStack用户的配置，写入和读取权限  [root@controller ~]# rabbitmqctl set_permissions openstack ".*" ".*" ".*" Setting permissions for user "openstack" in vhost "/" ...

7.Memcached缓存

7.1安装所需要的包 [root@controller ~]# yum install memcached python-memcached -y 7.2启动服务，并设置开机自启动 [root@controller ~]# systemctl enable memcached.service Created symlink from /etc/systemd/system/multi-user.target.wants/memcached.service to /usr/lib/systemd/system/memcached.service. [root@controller ~]# systemctl start memcached.service
