spec 2016使用

1. 制作cassandra and ycsb

1.1 编译安装netcat

$ wget http://sourceforge.net/projects/netcat/files/netcat/0.5.0/netcat-0.5.0.tar.gz
$ tar -zxvf netcat-0.5.0.tar.gz
$ cd netcat-0.5.0
$ ./configure --prefix=/opt/netcat --build=arm
$ make -j
$ make install
$ nc --help

 1.2 cassandra错误排除

 1.2.1 日志/var/log/cassandra/cassandra.log报：

The stack size specified is too small, Specify at least 228k
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

解决：修改/etc/cassandra/cassandra-env.sh中JVM_OPTS="$JVM_OPTS -Xss512k"

1.3 搜集虚拟机信息出现错误

[root@harness support_script]# ./collect_support_data.sh remote_vm_sysinfo 172.16.101.13 cbuser /home/osgcloud/cbtool/credentials/cbtool_rsa /tmp/instance/

Note: This output shows SysV services only and does not include native
      systemd services. SysV configuration data might be overridden by native
      systemd configuration.

      If you want to list systemd services use 'systemctl list-unit-files'.
      To see services enabled on particular target use
      'systemctl list-dependencies [target]'.

需要安装brctl和dpkg，具体如下：

sudo yum install bridge-utils
sudo yum install dpkg

2. cbtool工具bug

2.1 连接到云后，当使用aiattach cassandra_ycsb时，容易出现：

无法发现flavors问题

解决方式：通过修改osk_cloud_ops.py
