centos7.5 安装openstack

系统环境：

CentOS-7.5

安装前需要修改 /etc/hosts文件，添加 127.0.0.1 node1 (node1 为当前机器名)
否则会报如下错误：
Could not start Service[rabbitmq-server]: Execution of '/sbin/service rabbitmq-server start' returned 1: Starting rabbitmq-server: FAILED - check /var/log/rabbitmq/startup_{log, _err}

 

安装步骤：

关闭防火墙
#systemctl stop firewalld.service
关闭selinux
找到/etc/selinux/config 文件把文件中的SELINUX=enforcing   改为SELINUXdisabled 即可

[root@node1 openstack]# sudo yum install -y http://rdo.fedorapeople.org/rdo-release.rpm
[root@node1 openstack]# sudo yum install -y openstack-packstack
[root@node1 openstack]# packstack --allinone

　注:此步骤时间较长,需要长时间等待
