openstack部署keystone组件控制节点安装（解决坑）

    在开源社区openstack官网的介绍中keystone作为第一个组件被介绍，足以显示其在整个OpenStack架构中的重要地位,那么今天就来给搭建讲解一个完整的openstack验证组件的配置文件方法，大家可以按照自己的实际情况进行修改。

本次的安装配置的内容是一个脚本，我把脚本的内容给大家完整的摘了出来，所以你也可以直接的复制粘贴里面的内容执行，同时你需要安装crudini这个软件包，在 Linux上执行yum -y install crudini 就可以完整该软件的安装，课程的环境如下所示：

  controller   eth0 10.37.129.10   eth1  10.211.55.10

  compute     eth0  10.37.129.11   eth1  10.211.55.11

 eth0为集群内通信的地址，即为私有地址， eth1是可以访问互联网的地址段，用于给云主机分配浮动地址，具体的操作步骤如下所示（该步骤是在控制节点操作）：

yum install -y openstack-keystone httpd mod_wsgi

mysql -uroot -p123456 -e "create database IF NOT EXISTS keystone ;"

mysql -uroot -p123456 -e "GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY '123456' ;"

mysql -uroot -p123456 -e "GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY '123456' ;"

crudini --set /etc/keystone/keystone.conf database connection  mysql+pymysql://keystone:123456@controller/keystone

ADMIN_TOKEN=$(openssl rand -hex 10)

crudini --set /etc/keystone/keystone.conf DEFAULT admin_token $ADMIN_TOKEN

crudini --set /etc/keystone/keystone.conf token provider  fernet

su -s /bin/sh -c "keystone-manage db_sync" keystone

keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone

sed -i "s/#ServerName www.example.com:80/ServerName controller/g" /etc/httpd/conf/httpd.conf 

cat >/etc/httpd/conf.d/wsgi-keystone.conf<<- EOF
