openstack私有云布署实践【7.1 keystone + memcache (科兴环境)】

其实登录数据库集群中任意1台都可以创建库，它们会实时自动同步数据库和对应的数据库权限。

 

首先登录kxcontroller1创建kx_keystone数据库，并赋于远程和本地访问的权限。

 

mysql -u root -p

CREATE DATABASE keystone;

GRANT ALL PRIVILEGES ON kx_keystone.* TO 'kx_keystone'@'localhost'   IDENTIFIED BY 'venic8888';

GRANT ALL PRIVILEGES ON kx_keystone.* TO 'kx_keystone'@'%'  IDENTIFIED BY 'venic8888';

flush PRIVILEGES;

 

2台controller服务器（kxcontrolelr1 kxcontroller2） 安装其它无状态服务的组件，

 

 

yum install openstack-keystone httpd mod_wsgi  memcached python-memcached -y

先开启memcache

systemctl enable memcached.service

systemctl start memcached.service

 

kxcontroller1上

vi  /etc/keystone/keystone.conf

 

[DEFAULT]

admin_token = venicchina

verbose = True

[database]

connection = mysql://keystone:venic8888@kxcontroller/kx_keystone

[memcache]

servers = kxcontroller1:11211

[token]

provider = uuid

driver = memcache

expiration = 86400

caching = true

cache_time = 86400

[revoke]

driver = sql

expiration_buffer = 86400

caching = true

cache_time = 86400

[catalog]

driver = keystone.catalog.backends.sql.Catalog

[identity]

driver = keystone.identity.backends.sql.Identity

 

kxcontroller2上

vi  /etc/keystone/keystone.conf

[DEFAULT]

admin_token = venicchina

verbose = True

[database]

connection = mysql://keystone:venic8888@kxcontroller/kx_keystone

[memcache]

servers = kxcontroller2:11211

[token]

provider = uuid

driver = memcache

expiration = 86400

caching = true

cache_time = 86400

[revoke]

driver = sql

expiration_buffer = 86400

caching = true

cache_time = 86400

[catalog]

driver = keystone.catalog.backends.sql.Catalog

[identity]

driver = keystone.identity.backends.sql.Identity

 

以上的每个配置中两组黄色底86400的是给token定义失效时间，默认30分钟或1小时，因为有时迁移一些很大的实例时，迁移大200G的时候，时间会超过，到时会有token报错，到时实例就废掉了。加大时长是必须，这里我定义1天超时

 

在其中一台kxcontroller1同步数据库，生成表单

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

 

---------------------------------------

修改httpd配置

 

kxcontroller1上

vi /etc/httpd/conf/httpd.conf

 

ServerName kxcontroller1

改

Listen 80 这一条为以下行：

Listen 10.120.42.1:80#与VIP监听的IP不同

 

kxcontroller2上

vi /etc/httpd/conf/httpd.conf

 

ServerName kxcontroller2

改

Listen 80 这一条为以下行：

Listen 10.120.42.2:80#与VIP监听的IP不同

 

 

 

------------------------------------------

kxcontroller1上

vi /etc/httpd/conf.d/wsgi-keystone.conf

 

Listen 10.120.42.1:5000

2台kxcontroller服务启动，加入开机自启

 

# systemctl enable httpd.service

# systemctl start httpd.service

 

验证：在haproxy的页面http://10.120.42.10:8888/stats上查看80 5000 35357端口状态转发是否成功
