opentsdb安裝部署(rpm方式)

1.下載安裝介質
我這里下載的是opentsdb-2.3.2.noarch.rpm

2.安裝GnuPlot
yum install gnuplot

3.安裝
[root@localhost soft]# rpm -ivh opentsdb-2.3.2.noarch.rpm
opentsdb會安裝到 /usr/share/ 下

4.配置
$ cd /usr/share/opentsdb
$ vim /usr/share/opentsdb/etc/opentsdb/opentsdb.conf

tsd.network.port = 4242
tsd.network.bind = 0.0.0.0
tsd.network.worker_threads = 8
tsd.http.staticroot = build/staticroot
tsd.http.cachedir = /tmp/opentsdb
tsd.core.auto_create_metrics = true
tsd.storage.hbase.zk_quorum = localhost:2181

5.在Hbase中創建表

$ cd /usr/share/opentsdb
$ env COMPRESSION=NONE HBASE_HOME=/opt/hbase-1.2.1 ./tools/create_table.sh

我這里的hbase是1.2.1的,直接腳本的時候發現tsdb表報錯誤
create 'tsdb',
{NAME => 't', VERSIONS => 1, COMPRESSION => 'NONE', BLOOMFILTER => 'ROW', DATA_BLOCK_ENCODING => 'NONE', TTL => 'FOREVER'}

ERROR: For input string: "FOREVER"

我將TTL => 'FOREVER'去掉后單獨執行成功

6.啟動
$ cd /usr/share/opentsdb
$ bash bin/tsdb tsd &
[1] 251022

7.登陸

8.如何使用
創建metric
使用如下命令
tsdb mkmetric sys.cpu.user
寫入數據
作為測試，我們可以使用telnet接口寫入兩條數據：
# telnet localhost 4242
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
put sys.cpu.user 1356998400 42.5 host=webserver01 cpu=0
put sys.cpu.user 1356999400 42.7 host=webserver01 cpu=0
讀取數據
可以使用命令行讀取剛才寫入的兩條數據：
# tsdb query 1356998400 1356999400 sum sys.cpu.user
sys.cpu.user 1356998400000 42.500000 {host=webserver01, cpu=0}
sys.cpu.user 1356999400000 42.700001 {host=webserver01, cpu=0}
