openstack O版基础环境的搭建

配置说明：
controller IP:192.168.0.111
Compute IP: 192.168.0.112
1.网络配置.
Controller
DEVICE=ens33
ONBOOT=yes
IPADDR=192.168.0.111
PREFIX0=24
GATEWAY=192.168.0.254
DNS1=192.168.0.254
Compute
DEVICE=ens33
ONBOOT=yes
IPADDR=192.168.0.112
PREFIX0=24
GATEWAY=192.168.0.254
DNS1=192.168.0.254
关闭两台服务器的iptables 和 selinux
(1)关闭防火墙
systemctl stop firewalld.service
systemctl disable firewalld.service
（2）关闭selinux
setenforce 0
[[email protected] ~]# setenforce 0
[[email protected] ~]# cat /etc/selinux/config
SELINUX=disabled
SELINUXTYPE=targeted
2.NTP服务的搭建
Controller
安装chrony时间同步服务（系统默认是安装），如果没有安装就安装。
[[email protected] ~]# rpm -qa | grep chrony
chrony-2.1.1-4.el7.centos.x86_64
[[email protected] ~]#yum -y install chrony
[[email protected] ~]# vi /etc/chrony.conf
安装好后，需要修改配置文件，如下所示：

启动ntp服务
[[email protected] ~]# systemctl start chronyd.service 启动ntp服务
[[email protected] ~]# systemctl status chronyd.service 查看时间同步状态
[[email protected] ~]# chronyc sources -v 查看时间同步源
[[email protected] ~]# chronyc sourcestats -v 查看时间同步源状态

Compute ntp的安装和部署
安装同上一样，安装好后修改配置文件
[[email protected] ~]# vi /etc/chrony.conf

启动服务和查看是否正常同上。
############################ controller Openstack包安装和部署##########################
一．MYSQL服务
[[email protected] ~]# yum -y install mariadb mariadb-server python2-PyMySQL 安装46个包
[[email protected] ~]# cd /etc/my.cnf.d/
[[email protected] my.cnf.d]# vi mariadb-openstack.cnf
[[email protected] my.cnf.d]# cat mariadb-openstack.cnf
[mysqld]
default-storage-engine = innodb
innodb_file_per_table
collation-server = utf8_general_ci
init-connect = ‘SET NAMES utf8‘
character-set-server = utf8
bind-address = 192.168.0.111
[[email protected] ~]# systemctl enable mariadb.service
[[email protected] ~]# systemctl start mariadb.service
[[email protected] ~]# netstat -anpult | grep mysqld
tcp 0 0 192.168.0.111:3306 0.0.0.0: LISTEN 2990/mysqld
初始化数据库
[[email protected] ~]# mysql_secure_installation
Enter current password for root (enter for none): 选择回车

[[email protected] ~]# yum -y install erlang
[[email protected] ~]# yum install -y rabbitmq-server
[[email protected] ~]# systemctl enable rabbitmq-server.service
[[email protected] ~]# systemctl start rabbitmq-server.service
[[email protected] ~]# systemctl status rabbitmq-server.service
[[email protected] ~]# systemctl list-unit-files |grep rabbitmq-server.service
[[email protected] ~]# rabbitmqctl add_user openstack devops 用户名为：openstack 密码：devops
