CentOS 7部署OpenStack--准备基础环境

操作指导：
   本文主要安装L版openstack，采用yum安装方式。  
   只有“#”的命令行表示在所有的节点均进行操作；命令行有主机名的表示仅在该主机上进行操作。
   另外，官方文档时间同步采用的是chrony，本文仍采用ntp服务。

服务器部署

系统环境

# uname -r
3.10.0-229.el7.x86_64
# cat /etc/redhat-release
CentOS Linux release 7.1.1503 (Core)

基础环境部署

配置hosts

# cat /etc/hosts
192.168.1.11 controller
192.168.1.12 compute
[root@controller ~]# ping -c1 compute
PING compute (192.168.1.12) 56(84) bytes of data.
64 bytes from compute (192.168.1.12): icmp_seq=1 ttl=64 time=0.370 ms

--- compute ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.370/0.370/0.370/0.000 ms
[root@compute ~]# ping -c1 controller
PING controller (192.168.1.11) 56(84) bytes of data.
64 bytes from controller (192.168.1.11): icmp_seq=1 ttl=64 time=1.00 ms

--- controller ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 1ms
rtt min/avg/max/mdev = 1.005/1.005/1.005/0.000 ms

配置ntp

[root@controller ~]# yum install -y ntp
[root@controller ~]# vim /etc/ntp.conf
15 restrict -6 ::1
16 restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap
27 restrict 0.centos.pool.ntp.org nomodify notrap noquery
28 restrict 1.centos.pool.ntp.org nomodify notrap noquery
29 restrict 2.centos.pool.ntp.org nomodify notrap noquery
30 restrict 3.centos.pool.ntp.org nomodify notrap noquery
31 server 127.127.1.0
32 fudge 127.127.1.0 stratum 10
[root@controller ~]# systemctl enable ntpd
[root@controller ~]# systemctl start ntpd

在控制节点可计算节点配置定时任务

[root@compute ~]# crontab -l
*/5 * * * * /usr/sbin/ntpdate 192.168.1.11 >/dev/null 2>&1

关闭防火墙

# systemctl stop firewalld

关闭selinux

# sed -i ‘s/SELINUX=enforcing/SELINUX=disabled/g‘ /etc/selinux/config  //需要重启才能生效

安装基础包

[root@controller ~]# yum install -y http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm
[root@controller ~]# yum install -y centos-release-openstack-liberty
[root@controller ~]# yum install -y python-openstackclient

安装mysql

[root@controller ~]# yum install -y mariadb mariadb-server MySQL-python
[root@controller ~]# cp /usr/share/mysql/my-medium.cnf /etc/my.cnf
[root@controller ~]# vim /etc/my.cnf

在mysqld模块添加如下几行：

default-storage-engine = innodb
innodb_file_per_table
collation-server = utf8_general_ci  
init-connect = ‘SET NAMES utf8‘
character-set-server = utf8
[root@controller ~]# systemctl enable mariadb.service
[root@controller ~]# systemctl start mariadb.service
[root@controller ~]# mysql_secure_installation //设置root密码

具体步骤就不列出了

安装rabbitmq

[root@controller ~]# yum install -y rabbitmq-server
[root@controller ~]# systemctl enable rabbitmq-server.service
[root@controller ~]# systemctl start rabbitmq-server.service
[root@controller ~]# rabbitmqctl add_user openstack openstack
Creating user "openstack" ...
...done.
[root@controller ~]# rabbitmqctl set_permissions openstack ".*"".*" ".*"
Setting permissions for user "openstack" in vhost "/"...
...done.
[root@controller ~]# rabbitmq-plugins enable rabbitmq_management
[root@controller ~]# systemctl restart rabbitmq-server.service

在浏览器中输入http://192.168.1.11:15672，默认账户和密码为guest。登录后将前面创建的openstack用户加入到admin中，结果如下图：
