OpenTSDB 1.0 安装

> 安装一个实例

1.[安装Hbase](/blog/post/admin/Hbase_install_standalone)
***
2.安装 gnuplot
yum list |grep gnuplot
***
3.编译包
mkdir /leo/opentsdb
cd /leo/opentsdb/
tar -xzvf /tmp/opentsdb-2.3.0.tar.gz
cd opentsdb-2.3.0/
mkdir build
cp -r third_party/ build/
./build.sh
***
4.创建Hbase 的表，一个Hbase集群只需要跑一次
env COMPRESSION=NONE HBASE_HOME=/leo/hbase/hbase-1.2.5/ ./src/create_table.sh
***
5.编辑配置文件
cd build
mkdir tmp
cp ../src/opentsdb.conf ./
vim opentsdb.conf
```
# --------- NETWORK ----------
# The TCP port TSD should use for communications
# *** REQUIRED ***
tsd.network.port = 4242       #监听端口

# The IPv4 network address to bind to, defaults to all addresses
# tsd.network.bind = 0.0.0.0

# Disable Nagel's algorithm, default is True
#tsd.network.tcp_no_delay = true

# Determines whether or not to send keepalive packets to peers, default
# is True
#tsd.network.keep_alive = true

# Determines if the same socket should be used for new connections, default
# is True
#tsd.network.reuse_address = true

# Number of worker threads dedicated to Netty, defaults to # of CPUs * 2
#tsd.network.worker_threads = 8

# Whether or not to use NIO or tradditional blocking IO, defaults to True
#tsd.network.async_io = true

# ----------- HTTP -----------
# The location of static files for the HTTP GUI interface.
# *** REQUIRED ***
tsd.http.staticroot = /leo/opentsdb/opentsdb-2.3.0/build/staticroot/
#这个目录在build好的时候就已经有了

# Where TSD should write it's cache files to
# *** REQUIRED ***
tsd.http.cachedir = /leo/opentsdb/opentsdb-2.3.0/build/tmp/
#这个目录自己建

# --------- CORE ----------
# Whether or not to automatically create UIDs for new metric types, default
# is False
tsd.core.auto_create_metrics = true    #如果有新的数据项，自动建立

# Whether or not to enable the built-in UI Rpc Plugins, default
# is True
#tsd.core.enable_ui = true

# Whether or not to enable the built-in API Rpc Plugins, default
# is True
#tsd.core.enable_api = true

# --------- STORAGE ----------
# Whether or not to enable data compaction in HBase, default is True
#tsd.storage.enable_compaction = true

# How often, in milliseconds, to flush the data point queue to storage,
# default is 1,000
# tsd.storage.flush_interval = 1000

# Max number of rows to be returned per Scanner round trip
# tsd.storage.hbase.scanner.maxNumRows = 128

# Name of the HBase table where data points are stored, default is "tsdb"
#tsd.storage.hbase.data_table = tsdb

# Name of the HBase table where UID information is stored, default is "tsdb-uid"
#tsd.storage.hbase.uid_table = tsdb-uid

# Path under which the znode for the -ROOT- region is located, default is "/hbase"
#tsd.storage.hbase.zk_basedir = /hbase

# A comma separated list of Zookeeper hosts to connect to, with or without
# port specifiers, default is "localhost"
tsd.storage.hbase.zk_quorum = localhost        #hbase 在哪

# --------- COMPACTIONS ---------------------------------
# Frequency at which compaction thread wakes up to flush stuff in seconds, default 10
# tsd.storage.compaction.flush_interval = 10

# Minimum rows attempted to compact at once, default 100
# tsd.storage.compaction.min_flush_threshold = 100

# Maximum number of rows, compacted concirrently, default 10000
# tsd.storage.compaction.max_concurrent_flushes = 10000

# Compaction flush speed multiplier, default 2
# tsd.storage.compaction.flush_speed = 2

tsd.http.query.allow_delete = true  #允许删除数据
```
***
6.启动
nohup  ./tsdb  tsd &
现在可以通过浏览器访问4242端口了
