大数据组件sqoop部署安装与测试练习

环境说明

10.176.2.101 master
10.176.2.103 zjx03
10.176.2.105 zjx05

cent-os6.5
zookeeper cdh 3.4.5
hadoop apache 2.7.7

sqoop安装

本人将sqoop部署在master机器上，mysql安装在zjx03上

1 下载sqoop应用包

mkdir /opt/softwares/
cd /opt/softwares
wget https://mirrors.tuna.tsinghua.edu.cn/apache/sqoop/1.4.7/sqoop-1.4.7.bin__hadoop-2.6.0.tar.gz
tar –xzvf sqoop-1.4.7.bin__hadoop-2.6.0.tar.gz –C /opt/softwares
rm -rf sqoop-1.4.7.bin__hadoop-2.6.0.tar.gz

修改配置文件

cd /opt/softwares/sqoop-1.4.7.bin__hadoop-2.6.0/conf
cp sqoop-env-template.sh sqoop-env.sh
vim sqoop-env.sh

export HADOOP_COMMON_HOME=/opt/softwares/hadoop-2.7.7

#Set path to where hadoop-*-core.jar is available
export HADOOP_MAPRED_HOME=/opt/softwares/hadoop-2.7.7

#set the path to where bin/hbase is available
#export HBASE_HOME=

#Set the path to where bin/hive is available
#export HIVE_HOME=

#Set the path for where zookeper config dir is
export ZOOCFGDIR=/opt/softwares/zookeeper-3.4.5-cdh5.12.2

配置环境变量

vim /etc/profile (root用户或者使用vim ~/.bashrc)

export SQOOP_HOME=/opt/softwares/sqoop-1.4.7.bin__hadoop-2.6.0
export PATH=$PATH:$SQOOP_HOME/bin
export CLASSPATH=$CLASSPATH:${SQOOP_HOME}/lib

source /etc/profile

mysql环境准备

卸载系统自带的mysql
执行以下命令查看是否有自带mysql:

rpm -qa | grep mysql

如果发现有输出结果,那么执行以下命令依次删除:

rpm -e **** --nodeps

开始安装mysql
首先安装mysql客户端:

yum install mysql

然后安装mysql服务端:

yum install mysql-server  
yum install mysql-devel

至此mysql相关组件已经安装成功!
修改字符集
mysql的配置文件路径为:

/etc/my.cnf

在配置文件中加入如下配置来修改字符集(本机加上字符集有问题，暂将其注释):

vim /etc/my.cnf
default-character-set=utf8

启动和停止mysql

service mysqld start
service mysqld status
service mysqld stop

将mysql加入开机启动，下次重启机器就不用重启mysql服务

chkconfig --level 345 mysqld on
chkconfig --list | grep mysql

配置初始密码

mysqladmin -u root password root  (其中设置密码为root)

登录mysql

mysql -uroot  -proot

允许远程登录
sql:

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;
FLUSH RIVILEGES;

完成mysql环境准备

复制sqoop相关依赖包

下载一个mysql驱动jar包mysql-connector-java-5.1.33.jar放入{SQOOP_HOME}/lib，本地有的话

cp  ./mysql-connector-java-5.1.33-bin.jar ${SQOOP_HOME}/lib
cp $HADOOP_HOME/share/hadoop/common/hadoop-common-2.7.7.jar ${SQOOP_HOME}/lib

修改$SQOOP_HOME/bin/configure-sqoop

注释掉HCatalog，Accumulo检查(除非你准备使用HCatalog，Accumulo等HADOOP上的组件)

##Moved to be a runtime check in sqoop.
#if[ ! -d "${HCAT_HOME}" ]; then
#  echo "Warning: $HCAT_HOME does notexist! HCatalog jobs will fail."
#  echo 'Please set $HCAT_HOME to the root ofyour HCatalog installation.'
#fi

#if[ ! -d "${ACCUMULO_HOME}" ]; then
#  echo "Warning: $ACCUMULO_HOME does notexist! Accumulo imports will fail."
#  echo 'Please set $ACCUMULO_HOME to the rootof your Accumulo installation.'
#fi

#Add HCatalog to dependency list
#if[ -e "${HCAT_HOME}/bin/hcat" ]; then
# TMP_SQOOP_CLASSPATH=${SQOOP_CLASSPATH}:`${HCAT_HOME}/bin/hcat-classpath`
#  if [ -z "${HIVE_CONF_DIR}" ]; then
#   TMP_SQOOP_CLASSPATH=${TMP_SQOOP_CLASSPATH}:${HIVE_CONF_DIR}
#  fi
#  SQOOP_CLASSPATH=${TMP_SQOOP_CLASSPATH}
#fi

#Add Accumulo to dependency list
#if[ -e "$ACCUMULO_HOME/bin/accumulo" ]; then
#  for jn in `$ACCUMULO_HOME/bin/accumuloclasspath | grep file:.*accumulo.*jar |cut -d':' -f2`; do
#    SQOOP_CLASSPATH=$SQOOP_CLASSPATH:$jn
#  done
#  for jn in `$ACCUMULO_HOME/bin/accumuloclasspath | grep file:.*zookeeper.*jar |cut -d':' -f2`; do
#    SQOOP_CLASSPATH=$SQOOP_CLASSPATH:$jn
#  done
#fi

测试与mysql是否连通

sqoop list-databases --connect jdbc:mysql://10.176.2.103:3306/ --username root -P
#或者
sqoop list-databases --connect jdbc:mysql://10.176.2.103:3306/ --username root -password root
#同上述连通显示所有数据库
sqoop list-databases --username root --password root --connect jdbc:mysql://10.176.2.103:3306/

主机zjx03(10.176.2.103)登录mysql
mysql -uroot -proot

sql:
show databases;
# 数据库创建
CREATE DATABASE IF NOT EXISTS db_zjx default charset utf8 COLLATE utf8_general_ci;
# 数据库创建简单操作
create database db_zjx;
use db_zjx;
show tables;
create table tbl_sqoop(name varchar(11),age int ,sex varchar(11));
desc tbl_sqoop;
insert into tbl_sqoop value('zs',11,'girl');
insert into tbl_sqoop value('ls',12,'girl');
insert into tbl_sqoop value('zjx',25,'boy');
select * from tbl_sqoop;
exit;

主机master节点(10.176.2.101)进行sqoop操作,linux:

#列出数据库下的所有表
sqoop list-tables --username root --password root --connect jdbc:mysql://10.176.2.103:3306/db_zjx

sqoop导入导出操作练习

#将tbl_sqoop表中的数据导入到HDFS的/tmp/zhoujixiang/sqoop_data目录中(该目录自动创建)
sqoop import --username root --password root --connect jdbc:mysql://10.176.2.103:3306/db_zjx  --query "select * from tbl_sqoop where \$CONDITIONS" --target-dir  /tmp/zhoujixiang/sqoop_data/ --fields-terminated-by ',' --split-by id -m 1
hadoop fs -ls /tmp/
#查看导入HDFS的数据文件
hadoop fs -ls /tmp/zhoujixiang/
hadoop fs -ls /tmp/zhoujixiang/sqoop_data/
hadoop fs -cat /tmp/zhoujixiang/sqoop_data/*
# result
zs,11,girl
ls,12,girl
zjx,25,boy
