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.rpm error: Failed dependencies: gnuplot is needed by opentsdb-2.4.0-1.noarch
安裝OpenTSDB
[root@ecs opt]# rpm -ivh opentsdb-2.4.0.noarch.rpm

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

訪問頁面
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
