rabbitmq管理插件启动
[root@linux-node0 ~]# rabbitmq-plugins enable rabbitmq_management 
重新启动rabbitmq
[root@linux-node0 ~]# systemctl restart rabbitmq-server.service
再次查看监听的端口：web管理端口:15672
lsof -i:15672 查看进程
[root@linux-node0 ~]# netstat -lntup
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name    
tcp        0      0 0.0.0.0:25672           0.0.0.0:*               LISTEN      38649/beam          
tcp        0      0 0.0.0.0:3306            0.0.0.0:*               LISTEN      38154/mysqld        

打开http://192.168.31.151:15672  用户名 guest      密码 guest 
登录进去之后：
Admin------->复制administrator------->点击openstack------>Update this user-------->
Tags:粘帖administrator--------->密码都设置为openstack-------->loGout
然后在登陆：用户名 openstack  密码  openstack

[root@linux-node0 ~]# openssl rand -hex 10
 8097f01ca96d056655cf 产生的随机数
[root@linux-node0 ~]# grep -n '^[a-z]'  /etc/keystone/keystone.conf
12:admin_token =  8097f01ca96d056655cf

1349:driver = sql
1911:provider = uuid
1916:driver = memcache
同步数据库：注意权限，所以要用su -s 切换到keystone用户下执行：
[root@linux-node0 ~]# su -s /bin/sh -c "keystone-manage db_sync" keystone
No handlers could be found for logger "oslo_config.cfg"
验证数据是否创建成功
[root@linux-node0 ~]# mysql -ukeystone -pkeystone
MariaDB [(none)]> use keystone
Database changed
MariaDB [keystone]> show tables;

[root@linux-node0 ~]# systemctl enable memcached
[root@linux-node0 ~]# systemctl start memcached.service
必须要配置httpd的ServerName,否则keystone服务不能起来
[root@linux-node0 ~]# vi /etc/httpd/conf/httpd.conf
ServerName 192.168.1.17:80
[root@linux-node0 ~]# grep -n '^ServerName' /etc/httpd/conf/httpd.conf      
95:ServerName 192.168.1.17:80
新建keystone配置文件，并用apache来代理它：5000  正常的api来访问  35357  管理访问的端口

便快捷的使用keystone,我们需要设置两个环境变量：
[root@linux-node0 ~]# cat admin-openrc.sh 
export OS_PROJECT_DOMAIN_ID=default
export OS_USER_DOMAIN_ID=default
export OS_PROJECT_NAME=admin
export OS_TENANT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=admin
export OS_AUTH_URL=http://192.168.1.17:35357/v3
export OS_IDENTITY_API_VERSION=3
[root@linux-node0 ~]# cat demo-openrc.sh 
export OS_PROJECT_DOMAIN_ID=default
export OS_USER_DOMAIN_ID=default
export OS_PROJECT_NAME=demo

export OS_USERNAME=demo
export OS_PASSWORD=demo
export OS_AUTH_URL=http://192.168.1.17:5000/v3
export OS_IDENTITY_API_VERSION=3
添加执行权限
[root@linux-node0 ~]# chmod +x admin-openrc.sh demo-openrc.sh
