linux安装sqoop

一 解压安装包

这里提供了网盘资源

链接: https://pan.baidu.com/s/1QkFqVnlvuOJ_aB2bjn-OKg?pwd=ucsy 提取码: ucsy

这里有两个压缩包，sqoop-1.4.7.tar.gz是 sqoop 的安装包，另一个是我们需要里面的一些 jar 包

解压 安装包

tar -zxf ./sqoop-1.4.7.tar.gz -C /opt/soft

改个简单的名字方便后面操作

mv sqoop-1.4.7/ sqoop147

二 修改配置文件

到sqoop/conf 目录下，拷贝sqoop-env-template.sh文件到此目录命名sqoop-env.sh

 cp sqoop-env-template.sh sqoop-env.sh

修改sqoop-env.sh

vim sqoop-env.sh

#Set path to where bin/hadoop is available
export HADOOP_COMMON_HOME=/opt/soft/hadoop313


#Set path to where hadoop-*-core.jar is available
export HADOOP_MAPRED_HOME=/opt/soft/hadoop313

#set the path to where bin/hbase is available
export HBASE_HOME=/opt/soft/hbase235

#Set the path to where bin/hive is available
export HIVE_HOME=/opt/soft/hive312
export HIVE_CONF_DIR=/opt/soft/hive312/conf

#Set the path for where zookeper config dir is
export ZOOCFGDIR=/opt/soft/zk345/conf

三 拷贝 jar 包

（1）sqoop147目录下补全 jar 包

需要sqoop-1.4.7.bin__hadoop-2.6.0目录下的sqoop-1.4.7.jar，拷贝一份到 sqoop147 目录下

cp /opt/install/sqoop-1.4.7.bin__hadoop-2.6.0/sqoop-1.4.7.jar /opt/soft/sqoop147/

（2）lib 目录下补全 jar 包

这里命令执行在/opt/soft/sqoop147/lib里

cd /opt/soft/sqoop147/lib

 cp /opt/soft/hive312/lib/hive-common-3.1.2.jar ./

这个 mysql 驱动包在安装 hive 的时候复制过 ，所以我这里直接在这个目录就有，这个驱动包在这个目录没有的可以去hive 的bin目录里找找

cp /opt/install/mysql-connector-java-8.0.29.jar ./

cp /opt/install/sqoop-1.4.7.bin__hadoop-2.6.0/lib/avro-1.8.1.jar ./

四 修改环境变量

vim /etc/profile

#SQOOP
export SQOOP_HOME=/opt/soft/sqoop147
export PATH=$SQOOP_HOME/bin:$PATH

修改完source一下

source /etc/profile

五 查看 sqoop 版本以及测试连接

查看 sqoop 版本

sqoop version

[root@kb46 conf]# sqoop version
Warning: /opt/soft/sqoop147/../hcatalog does not exist! HCatalog jobs will fail.
Please set $HCAT_HOME to the root of your HCatalog installation.
Warning: /opt/soft/sqoop147/../accumulo does not exist! Accumulo imports will fail.
Please set $ACCUMULO_HOME to the root of your Accumulo installation.

查看 sqoop 的命令

sqoop help

连接 mysql 查看 MySQL 所有数据库

这里的 ip 还有mysql密码 换成自己的

这里还有一个小技巧，在命令行敲sqoop命令时\代表连接符，\后回车接着写，是一句命令

 sqoop list-databases --connect jdbc:mysql://172.25.**.**:3306/ --username root --password password

结果实例：

[root@kb46 conf]# sqoop list-databases --connect jdbc:mysql://172.25.38.169:3306/ --username root --password 100860
