记录Presto数据查询引擎的配置过程 - 夜丶帝 - 博客园

配置准备:

1、centos6.4系统的虚拟机4个(master、secondary、node1、node2)

2、准备安装包

    hadoop-cdh4.4.0、hive-cdh4.4.0、presto、discovery-server、hbase、JDK7.0+64bit、pythin2.4+、postgresql

3、配置规划
    主机:192.168.69.180 master  (hadoop、hbase、discovery-server、hive、presto、postgresql)
    副主机:192.168.69.181 secondary(hadoop、hbase、presto)
    节点:192.168.69.182 node1(hadoop、hbase、presto),192.168.69.183 node2(hadoop、hbase、presto)
 
配置步骤:
1、在每个虚拟机上安装Java JDK和python。
2、修改每台虚拟机的hosts文件,如下红色部分:
[root@master ~]# cat /etc/hosts
127.0.0.1   localhost
::1         localhost 
192.168.69.180     master
192.168.69.181     secondary
192.168.69.182     node1
192.168.69.182     node3
3、关闭所有虚拟机的防火墙,命令如下:
[root@master~]# service iptables stop
4、配置主机与节点机无密码连接(以master与secondary为例,红色部分不录入):
master:
[root@master:~]$mkdir .ssh
[root@master:~]$cd .ssh
[root@master:.ssh]$ssh-keygen  -t  rsa(执行该命令后输入名称,这里为方便使用master,输入执行后继续按提示输入密码,如:123456)
[root@master:.ssh]$cp master.pub authorized_keys(将公钥加入authorized_keys)
[root@master:.ssh]$scp master.pub secondary:/root/.ssh/(执行该命令将master.pub同步到secondary的/root/.ssh/,然后在secondary中执行cp master.pub authorized_keys命令,同样,将master.pub同步到node1和node2执行同样命令)
secondary:
[root@secondary:~]$mkdir .ssh
[root@secondary:~]$cd .ssh
[root@secondary:.ssh]cp master.pub authorized_keys
[root@secondary:.ssh]$ssh-keygen  -t  rsa(执行该命令后输入名称,这里为方便使用secondary,输入执行后继续按提示输入密码,如:123456)
[root@secondary:.ssh]$cat secondary.pub >> authorized_keys(将公钥追加authorized_keys)
[root@secondary:.ssh]$scp secondary.pub master:/root/.ssh/(执行该命令将secondary.pub同步到master的/root/.ssh/,然后在master中执行cat secondary.pub >> authorized_keys命令将公钥追加到authorized_keys中)

注:Ssh 权限配置问题:
用户目录权限为 755 或者 700就是不能是77x
.ssh目录权限必须为755
rsa_id.pub 及authorized_keys权限必须为644
rsa_id权限必须为600
最后,在master中测试:ssh master date、ssh secondary date、ssh node1 date、ssh node2 date 不需要密码,则成功。
如果ssh secondary 、ssh node1、ssh node2 连接速度慢,需要更改/etc/ssh/ssh_config 为GSSAPIAuthentication no

修改root的ssh权限,/etc/ssh/sshd_config,将PermitRootLogin no 改为yes
重启sshd服务:/etc/init.d/sshd restrat

5、配置环境变量

[root@master~]# gedit .bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

# User specific environment and startup programs
export JAVA_HOME=/usr/java/jdk1.7.0_45
export JRE_HOME=$JAVA_HOME/jre
export CLASS_PATH=./:$JAVA_HOME/lib:$JRE_HOME/lib:$JRE_HOME/lib/tools.jar:/usr/presto/server/lib:/usr/discovery-server/lib

export HADOOP_HOME=/usr/hadoop
export HIVE_HOME=/usr/hive
export HBASE_HOME=/usr/hbase

export HADOOP_MAPRED_HOME=${HADOOP_HOME}
export HADOOP_COMMON_HOME=${HADOOP_HOME}
export HADOOP_HDFS_HOME=${HADOOP_HOME}
export YARN_HOME=${HADOOP_HOME}
export HADOOP_YARN_HOME=${HADOOP_HOME}
export HADOOP_CONF_DIR=${HADOOP_HOME}/etc/hadoop
export HDFS_CONF_DIR=${HADOOP_HOME}/etc/hadoop
export YARN_CONF_DIR=${HADOOP_HOME}/etc/hadoop

export PATH=$PATH:$HOME/bin:$JAVA_HOME/bin:$HADOOP_HOME/sbin:$HIVE_HOME/bin:$HBASE_HOME/bin 
master环境变量配置好后,secondary、node1和node2同样配置,可以使用scp命令同步到secondary、node1和node2中

9、安装postgresql(用postgresql作为元数据库)

a、下载postgresql,并安装
b、使用pgadmin创建用户sa
c、使用pgadmin创建数据库testdb,并指定所属角色为sa
d、配置pg_hba.conf的访问地址,允许主机访问
e、配置postgresql.conf 
     standard_conforming_strings = off
f、复制postgres 的jdbc驱动 到 /usr/hive-cdh4.4.0/lib

10、安装presto
a、下载并解压到/usr下,即:/usr/presto
b、presto文件夹中创建etc文件夹,并在其中建立以下配置文件

1)node.properties

node.environment=production
node.id=F25B16CB-5D5B-50FD-A30D-B2221D71C882
node.data-dir=/var/presto/data 
注意每台服务器node.id必须是唯一的
2)jvm.config
-server 
-Xmx16G
-XX:+UseConcMarkSweepGC
-XX:+ExplicitGCInvokesConcurrent
-XX:+CMSClassUnloadingEnabled
-XX:+AggressiveOpts
-XX:+HeapDumpOnOutOfMemoryError
-XX:OnOutOfMemoryError=kill -9 %p
-XX:PermSize=150M
-XX:MaxPermSize=150M
-XX:ReservedCodeCacheSize=150M
-Xbootclasspath/p:/var/presto/installation/lib/floatingdecimal-0.1.jar
下载floatingdecimal-0.1.jar包放在/var/presto/installation/lib/目录下
3)config.properties
coordinator=true
datasources=jmx
http-server.http.port=8080
presto-metastore.db.type=h2
presto-metastore.db.filename=var/db/MetaStore
task.max-memory=1GB
discovery-server.enabled=true
discovery.uri=http://master:8411
以上为master的配置,secondary、node1和node2中需将coordinator=true值改为false,将discovery-server.enabled=true删除掉
4)log.properties
com.facebook.presto=DEBUG
5)在/usr/presto/etc中创建catalog文件夹,并创建以下配置文件
jmx.properties
connector.name=jmx
hive.propertes
connector.name=hive-cdh4
hive.metastore.uri=thrift://master:9083

11、安装discovery-service
a、下载并解压 discovery-service压缩包,放在/usr下,即:/usr/ discovery-service
b、与presto配置一样,在 /usr/ discovery-service下创建etc文件夹,并在其中创建以下配置文件

1)node.properties
node.environment=production 
node.id=D28C24CF-78A1-CD09-C693-7BDE66A51EFD
node.data-dir=/var/discovery/data
2)jvm.config
-server 
-Xmx1G
-XX:+UseConcMarkSweepGC
-XX:+ExplicitGCInvokesConcurrent
-XX:+AggressiveOpts
-XX:+HeapDumpOnOutOfMemoryError
-XX:OnOutOfMemoryError=kill -9 %p
3)config.properties
http-server.http.port=8411

运行:

master机器上运行命令如下:

start-all.sh(启动每台机器上的hadoop)

start-hbase.sh启动每台机器上的hbase)

转入usr/disdiscovery-server/bin中启动disdiscovery-server,命令如下

laucher start //启动
laucher run //运行
转入/usr/hive/bin中启动hive,命令如下:
./hive --service hiveserver -p 9083  //thrift模式
master及每台节点机上运行如下命令:
转入/usr/presto/server/bin中启动presto,命令如下:
laucher start //启动
laucher run //运行
 
命令汇总:

1、启动hadoop命令:
hadoop namenode -format
hadoop datanode -format
start-all.sh
hadoop dfsadmin -safemode leave
hdfs dfsadmin -safemode leave
2、hive启动命令:
./hive
./hive --service hiveserver -p 9083 //thrift模式
3、hbase 命令
./start-hbase.sh
4、discovery-server命令:
laucher start //启动
laucher run //运行
lancher stop //停止
5、presto命令
laucher start //启动
laucher run //运行
lancher stop //停止
6、presto 客户端启动
./presto --server localhost:8080 --catalog hive --schema default

测试:
在master机上运行presto的客户端,命令如下:
转入/usr/presto/client启动客户端,命令如下:
./presto --server localhost:8080 --catalog hive --schema default
客户端启动后执行 show tables;看是否成功
测试结果如下: 
以下测试虚拟机配置为:CentOS64bit  内存3个为2G 1个为1G    数据量为61W
 
 节点数     sql语句                                                                                                          执行时间(秒)

4 nodes   select Count(*) from mytable;                                                                                  10s

4 nodes   select Count(*),num from mytable group by num;                                                      10s

4 nodes   select num from mytable group by num having count(*)>1000;                                    10s

4 nodes   select min(num) from mytable group by num;                                                              9s

4 nodes   select min(num) from mytable;                                                                                   9s

4 nodes   select max(num) from mytable;                                                                                  9s

4 nodes   select min(num) from mytable group by num;                                                               9s

4 nodes   select row_number() over(partition by name order by num) as row_index from mytable;   16s
