进入目录 /usr/share/opentsdb/etc/opentsdb 修改配置文件 opentsdb.conf

tsd.http.staticroot = /usr/share/opentsdb/static/
tsd.http.cachedir = /tmp/opentsdb
tsd.core.plugin_path = /usr/share/opentsdb/plugins初始化OpenTSDB表
进入目录/usr/share/opentsdb/tools，修改create_table.sh

启动TSDB
nohup sh /usr/share/opentsdb/bin/tsdb tsd >tsdb-start.log &访问页面
写入数据
上面如果没有设置 tsd.core.auto_create_metrics = true 参数时，需要手动创建 metric
tsdb mkmetric sys.cpu.user否则会提示异常如下
[root@ecs-t-001-0002 ~]# telnet ip port
Escape character is '^]'.
put sys.cpu.user 1588302377 42.5 host=webserver01 cpu=0
put: unknown metric: No such name for 'metrics': 'sys.cpu.user'
加入两条数据，我们使用 telnet 方式添加数据，
put sys.cpu.user 1588292377 45.5 host=webserver01 cpu=0
put sys.cpu.user 1588302377 41.5 host=webserver01 cpu=0
再web页面我们简单查询看一下数据，右下角的一根线就是我们刚刚插入的两个点连成的线
这回我们插入四条数据，写入两个host
put sys.cpu.user 1588292377 45.5 host=webserver01 cpu=0
put sys.cpu.user 1588302377 41.5 host=webserver01 cpu=0
put sys.cpu.user 1588292377 12.5 host=webserver02 cpu=0
put sys.cpu.user 1588302377 80.5 host=webserver02 cpu=0我们再指定tags查询看看效果，指定webserver02小时如下，结果是从12.5-80.5两个点没问题
看下webserver01,数据也没问题
至此，服务安装与初步使用介绍完成，下一步介绍下Api接口使用
