CDH安装

opentsdb使用的hbase用cdh安装

要点：

• 配置内网yum源及parcels仓库
• master节点上安装cloudera-manager-server-db-2
• 先启动cloudera-manager-server-db-2， 设置JAVAHOME，启动cloudera-maanger-server * 通过浏览器访问http://master_ip:7180 * 使用内网parcels及yum源

  LZO支持

  准备内网gplextras5 parcels仓库，cdh安装此parcels，并在io.compression.codecs属性值中追加如下值： <code> com.hadoop.compression.lzo.LzoCodec com.hadoop.compression.lzo.LzopCodec </code>

  create.sh脚本

  设置HBASEHOME

export HBASE_HOME=/letv/cloudera/parcels/CDH-5.7.6-1.cdh5.7.6.p0.6/lib/hbase/

添加TTL

create.sh

#!/bin/sh
# Small script to setup the HBase tables used by OpenTSDB.
 
test -n "$HBASE_HOME" || {
  echo >&2 'The environment variable HBASE_HOME must be set'
  exit 1
}
test -d "$HBASE_HOME" || {
  echo >&2 "No such directory: HBASE_HOME=$HBASE_HOME"
  exit 1
}
 
TSDB_TABLE=${TSDB_TABLE-'tsdb'}
UID_TABLE=${UID_TABLE-'tsdb-uid'}
TREE_TABLE=${TREE_TABLE-'tsdb-tree'}
META_TABLE=${META_TABLE-'tsdb-meta'}
BLOOMFILTER=${BLOOMFILTER-'ROW'}
# LZO requires lzo2 64bit to be installed + the hadoop-gpl-compression jar.
COMPRESSION=${COMPRESSION-'LZO'}
# All compression codec names are upper case (NONE, LZO, SNAPPY, etc).
COMPRESSION=`echo "$COMPRESSION" | tr a-z A-Z`
 
case $COMPRESSION in
  (NONE|LZO|GZIP|SNAPPY)  :;;  # Known good.
  (*)
    echo >&2 "warning: compression codec '$COMPRESSION' might not be supported."
    ;;
esac
 
# HBase scripts also use a variable named `HBASE_HOME', and having this
# variable in the environment with a value somewhat different from what
# they expect can confuse them in some cases.  So rename the variable.
hbh=$HBASE_HOME
unset HBASE_HOME
exec "$hbh/bin/hbase" shell <<EOF
