OpenStack版本升级之Keystone

下载新版本并备份相关文件及数据

前面已经比较过Keystone在E版和F版中的一些差异，现在该是升级的时候了。原Keystone的Essex版本是在CentOS6.2下通过源代码安装的，后面在epel的rpm安装包找了个init脚本，使得Keystone能通过service管理并在开机时自动运行，因此这里仍然通过源代码进行升级。以防万一，首先要备份相关旧版的文件、数据，要备份的文件主要包括/usr/bin下的三个文件，/etc/keystone下的所有配置文件以及数据库keystone，命令如下所示：

[root@stackcc update_keystone]# wget https://launchpad.net/keystone/folsom/2012.2/+download/keystone-2012.2.tar.gz
[root@stackcc update_keystone]# mkdir -p backup/bin
[root@stackcc update_keystone]# cp /usr/bin/keystone* backup/bin/
[root@stackcc update_keystone]# mkdir backup/etc
[root@stackcc update_keystone]# cp /etc/keystone/* backup/etc/
[root@stackcc update_keystone]# mysqldump -ukeystone -p keystone > backup/keystone.sql

停止Keystone服务并安装F版Keystone

[root@stackcc update_keystone]# service keystone stop
[root@stackcc update_keystone]# tar -zxf keystone-2012.2.tar.gz 
[root@stackcc update_keystone]# cd keystone-2012.2
[root@stackcc keystone-2012.2]# python setup.py install > keystone.info

配置F版Keystone

主要修改了admin_token、log选项、sql选项、token和ec2选项，如下所示：

[root@stackcc keystone-2012.2]# rm -fr /etc/keystone/*
[root@stackcc keystone-2012.2]# cp etc/* /etc/keystone/
[root@stackcc keystone-2012.2]# ll /etc/keystone/

最后测试从Horizon登录，创建实例再删除，从Object Store下载一个小文件，上传文件，删除文件均正常。因此Keystone的升级算圆满完成了。接下来考虑Glance的升级。。。
