druid.io本地集群搭建 / 扩展集群搭建

druid.io 是一个比较重型的数据库查询系统，分为5种节点。

在此就不对数据库进行介绍了，如果有疑问请参考白皮书：

单台机器的集群搭建

首先说一下通用的集群搭建，基于 0.9.1.1

修改 conf/druid/_common 内的 common.runtime.properties，参考如下配置：

0.9.1.1 默认是不带mysql 扩展的需要自己下载，解压后放置于extensions 下：

参考文章：

分别修改5个节点的启动配置

/conf/druid/${serviceName}/runtime.properties

启动集群启动可以利用我写的脚本：

#java `cat conf/druid/broker/jvm.config | xargs` -cp conf/druid/_common:conf/druid/broker:lib/* io.druid.cli.Main server broker
function help(){
echo "参数列表"
echo " 参数1 参数2"
echo " serviceName [-f]"
echo "参数1：serviceName: 启动服务的名字"
echo "serviceName可选项:"
echo "1: broker"
echo "2: coordinator"
echo "3: historical"
echo "4: middleManager"
echo "5: overlord"
echo "参数2：[-f]: 是否前台启动"
echo "-f:前台启动，(不加)默认后台启动"
}
function startService(){
# echo $0
# echo $1
# echo $2
echo $service
if [[ $2 == "-f" ]]; then
echo "前台启动"
java -Xmx256m -Duser.timezone=UTC -Dfile.encoding=UTF-8 -classpath conf/druid/_common:conf/druid/$service:lib/* io.druid.cli.Main server $service
else
echo "后台启动"
nohup java -Xmx256m -Duser.timezone=UTC -Dfile.encoding=UTF-8 -classpath conf/druid/_common:conf/druid/$service:lib/* io.druid.cli.Main server $service &
fi;
}
function tips(){
red=`tput setaf 1`
reset=`tput sgr0`
echo "${red}Not correct arguments${reset}"
echo "please use --help or -h for help"
}
if [[ $1 == "--help" || $1 == "-h" ]]; then
help
exit
fi
service=$1
case $service in
"broker")
;;
"coordinator")
;;
"historical")
;;
"middleManager")
;;
"overlord")
;;
*)
tips
exit
esac
if [[ $2 == "-f" || $2 == "" ]]; then
startService $1 $2;
else
tips
exit
fi
