kanyun的部署
1 全部节点
1.1 安装zmq
安装zerozmq(2.2.0)
- yum install libtool autoconf automake
- yum install uuid-devel
- yum install libuuid-devel
- wget http://download.zeromq.org/zeromq-2.2.0.tar.gz
- tar zxvf zeromq-2.2.0.tar.gz & cd zeromq-2.2.0 & ./configure & make install
- ldconfig
安装pyzmq
- easy_install "pyzmq==2.2.0"
- 如果出现缺少libzmq.so.1的情况，可能是链接库没有正确配置。
- sudo /sbin/ldconfig -v | grep libzmq查看是否有所需链接
- 如果没有libzmq.so.1 -> libzmq.so.1.0.1，则修改/etc/ld.so.conf，在末尾增加/usr/local/lib，然后ldconfig -v | grep libzmq即可
- 如果出现缺少Python.h，则使用yum install python-devel来安装
1.2 安装kanyun
下载代码
kanyun原来的代码有bug，而且不能在python2.6环境下使用，下面是我改过的
cd /opt
git clone https://github.com/suyan/kanyun.git
修改内容：
- 兼容python2.6和2.7（python2.6需要安装OrderedDict）
- 修改获取内存信息方式和计算cpu使用率方式
- 修复一些bug
安装
python /opt/kanyun/setup.py install
创建日志目录
mkdir /var/log/kanyun
安装OrderedDict(python2.6)
easy_install OrderedDict
2 控制节点
2.1 安装配置cassandra
下载Cassandra
cd /opt
wget http://mirror.bit.edu.cn/apache/cassandra/0.8.10/apache-cassandra-0.8.10-bin.tar.gz
解压
tar zxvf apache-cassandra-0.8.10-bin.tar.gz
运行
/opt/apache-cassandra-0.8.10/bin/cassandra
创建数据库
通过命令打开数据库
/opt/apache-cassandra-0.8.10/bin/cassandra-cli -h 127.0.0.1
并执行下面命令
CREATE keyspace DATA;
USE DATA;
CREATE COLUMN family vmnetwork WITH column_type='Super' AND comparator='AsciiType' AND subcomparator='IntegerType' AND default_validation_class='AsciiType';
CREATE COLUMN family cpu WITH column_type='Super' AND comparator='AsciiType' AND subcomparator='IntegerType' AND default_validation_class='AsciiType';
CREATE COLUMN family mem_max WITH column_type='Super' AND comparator='AsciiType' AND subcomparator='IntegerType' AND default_validation_class='AsciiType';
CREATE COLUMN family mem_free WITH column_type='Super' AND comparator='AsciiType' AND subcomparator='IntegerType' AND default_validation_class='AsciiType';
CREATE COLUMN family nic_incoming WITH column_type='Super' AND comparator='AsciiType' AND subcomparator='IntegerType' AND default_validation_class='AsciiType';
CREATE COLUMN family nic_outgoing WITH column_type='Super' AND comparator='AsciiType' AND subcomparator='IntegerType' AND default_validation_class='AsciiType';
CREATE COLUMN family blk_read WITH column_type='Super' AND comparator='AsciiType' AND subcomparator='IntegerType' AND default_validation_class='AsciiType';
CREATE COLUMN family blk_write WITH column_type='Super' AND comparator='AsciiType' AND subcomparator='IntegerType' AND default_validation_class='AsciiType';
assume vmnetwork KEYS AS ascii;
assume cpu KEYS AS ascii;
assume mem_max KEYS AS ascii;
assume nic_incoming KEYS AS ascii;
assume nic_outgoing KEYS AS ascii;
assume blk_read KEYS AS ascii;
assume blk_write KEYS AS ascii;
assume mem_free KEYS AS ascii;
安装pycassa支持
easy_install pycassa
如果出现The required version of distribute is not available
easy_install -U distribute
2.2 启动和配置kanyun
配置/etc/kanyun.conf
- 文件中host需要填写计算节点的ip
- sql_connection填写nova.conf中connection值
配置文件
[kanyun]
log: /var/log/kanyun/kanyun.log
[DEFAULT]
sql_connection: mysql://nova:novamysqlpassword@controller/nova
[server]
host: 172.19.9.1
port: 5551
