安裝 GnuPlot

yum install gnuplot -y

直接安裝OpenTSDB會報錯

[root@ecs-t-001-0001 openTSDB]# rpm -ivh opentsdb-2.4.0.noarch.rpmerror: Failed dependencies: gnuplot is needed by opentsdb-2.4.0-1.noarch

?安裝OpenTSDB

默認配置目錄

修改配置

進入目錄 /usr/share/opentsdb/etc/opentsdb 修改配置文件 opentsdb.conf

> vim opentsdb.conftsd.storage.hbase.zk_quorum = zk:2181 tsd.network.port = 10080 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

進入目錄/usr/share/opentsdb/tools，修改create_table.sh

我們加入的內容

HBASE_HOME=/opt/cloudera/parcels/CDH-6.3.2-1.cdh6.3.2.p0.1605554/lib/hbase COMPRESSION=SNAPPY

啟動TSDB

寫入數據

上面如果沒有設置 tsd.core.auto_create_metrics = true 參數時，需要手動創建 metric

tsdb mkmetric sys.cpu.user

否則會提示異常如下

[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'

?

加入兩條數據，我們使用 telnet 方式添加數據，

put sys.cpu.user 1588292377 45.5 host=webserver01 cpu=0 put sys.cpu.user 1588302377 41.5 host=webserver01 cpu=0

?

再web頁面我們簡單查詢看一下數據，右下角的一根線就是我們剛剛插入的兩個點連成的線

這回我們插入四條數據，寫入兩個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

我們再指定tags查詢看看效果，指定webserver02小時如下，結果是從12.5-80.5兩個點沒問題

看下webserver01,數據也沒問題

至此，服務安裝與初步使用介紹完成，下一步介紹下Api接口使用
