openstack O版 基础环境的搭建

云计算
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
[root@compute ~]# setenforce 0
[root@compute ~]# 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。
[root@controller ~]# rpm -qa | grep chrony
chrony-2.1.1-4.el7.centos.x86_64
[root@controller ~]#yum -y install chrony
[root@controller ~]# 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
[root@controller ~]# systemctl start chronyd.service 启动ntp服务
[root@controller ~]# systemctl status chronyd.service 查看时间同步状态
[root@controller ~]# chronyc sources -v 查看时间同步源
[root@controller ~]# 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
[root@compute ~]# 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
[root@controller ~]# yum -y install mariadb mariadb-server python2-pymysql 安装46个包
[root@controller ~]# cd /etc/my.cnf.d/
[root@controller my.cnf.d]# vi mariadb-openstack.cnf
[root@controller 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
[root@controller ~]# systemctl enable mariadb.service
[root@controller ~]# systemctl start mariadb.service
[root@controller ~]# 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
[root@controller ~]# mysql_secure_installation
enter current password for root (enter for none): 选择回车
set root password? [y/n] y
设置密码及初始化
密码 devops ，一路y回车
[root@controller ~]# mysql -uroot -pdevops
创建数据库
[root@controller ~]# mysql -uroot -pdevops

二．rabbitmq服务的安装
[root@controller ~]# yum -y install erlang
[root@controller ~]# yum install -y rabbitmq-server
[root@controller ~]# systemctl enable rabbitmq-server.service
[root@controller ~]# systemctl start rabbitmq-server.service
[root@controller ~]# systemctl status rabbitmq-server.service
[root@controller ~]# systemctl list-unit-files |grep rabbitmq-server.service
[root@controller ~]# rabbitmqctl add_user openstack devops 用户名为：openstack 密码：devops
creating user "openstack" …
[root@controller ~]# rabbitmqctl set_user_tags openstack administrator 设置openstack为管理员
setting tags for user "openstack" to [administrator] …
[root@controller ~]# rabbitmqctl set_permissions openstack "." "." "."
