完成上述配置后，还需要在cassandra中进行调整，根据官方建议如下：
The row size has been a point of some confusion. Basically it comes down to this: The more data you can fit into a single row the better the system will perform when querying the data. This does not mean that Cassandra only holds 3 weeks worth of data, it means data is written to the same row for 3 weeks before going to a new row. See the [CassandraSchema cassandra schema for more details].
Changing the read_repair_chance: This value tells cassandra how often to perform a read repair. The read repair chance will default to 1 (100% chance). The recommended value is 0.1 (10% chance). To change this log into the cassandra-cli client and run the following commands
> use kairosdb;
> update column family data_points with read_repair_chance = 0.1;
> update column family row_key_index with read_repair_chance = 0.1;
> update column family string_index with read_repair_chance = 0.1;
Note: If you are using the newer cqlsh command, you will need to use the alter syntax
> use kairosdb;
> ALTER TABLE data_points WITH read_repair_chance = 0.1;
> ALTER TABLE row_key_index WITH read_repair_chance = 0.1;
> ALTER TABLE string_index WITH read_repair_chance = 0.1;

通过浏览器访问http://192.168.56.102:9999/ 可以看到web界面
查看kairosdb 是否成功运行在cassandra 上
是否有创建 keyspace kairosdb
[cassandra@k8s2 bin]$ ./cqlsh
No appropriate python interpreter found.
报错提示缺少python，这里目前版本需要安装python2.7,而centos里自带的是python3.6,需要修改下
切换到阿里源下，直接yum安装
[cassandra@k8s2 ~]$ sudo yum install python2
安装后，进行查看
[cassandra@k8s2 bin]$ ./cqlsh 192.168.56.102 9042
cqlsh> desc keyspaces;
system_schema system_auth system kairosdb system_distributed system_traces
配置kairosdb 用户密码
#kairosdb.jetty.basic_auth.user=
#kairosdb.jetty.basic_auth.password=
默认cashe 路径(可以在config 中修改)
