2、消息队列

使用mirror-queue mode,详细部署方式,参见禅道上的rabbtmq集群部署文档。

 

3、数据库

使用mariaDB+innodb+gelera,版本10.0.18以上, 详细部署方式,参见禅道上的rabbtmq集群部署文档。

 

4、中间件

使用memcached,未采用集群形式,编辑/etc/sysconfig/memcached,修改127.0.0.1为本地主机名(或者IP)。

 

二、部署方案

本机使用controller1作为认证名,

所有服务密码使用$MODULE+manager,例如:novamanagerglancemanager

数据库使用dftc+$MODULE例如:DB_PASSDB_PASS

规划IP段:172.16.16.0/24作为管理网段;172.16.17.0/24存储网段;172.16.18.0/23作为外部网络的网段。

操作之前使用MYIP=`ip add show em1|grep inet|head -1|awk  '{print $2}'|awk-F'/' '{print  $1}'`赋值变量

本文使用flat+vxlan网络部署方式,如果需要更改,请自行百度;

Issue: glance模块使用本地存储,无法上传镜像

Resolution:

检查端口9292是否启动,是否可以telnet。检查发现端口无法启动,重新检查配置文件,与ceph对接不能使用“virt_type”的选项,ceph自身直接使用rbd格式对所有的对象进行统一标记管理;

 

ID005

Issue: 创建虚拟机失败,界面提示链接http://controller:9696失败

Resolution:

检查9696端口启用正常,本地主机名实际为controller1,更新配置文件/etc/nova/nova.conf

ID006

Issue: glance-api显示服务正常,端口每10秒出现一次,无法正常链接;api日志无异常输出,systemctl status抛出python异常ERROR:Store for schema file not found

ceph对接过程使用default_store在旧版本中添加在[DEFAULT]选项之后,新版本中添加到[glance]选项之后,更新之后正常

default_store = rbd

 

 

ID007
