3.1.1 下载sqoop1：
sqoop-1.4.7.bin__hadoop-2.6.0.tar.gz

3.1.2 解压并查看目录：

[hadoop@hadoop01 ~]$ tar -zxvf sqoop-1.4.7.bin__hadoop-2.6.0.tar.gz --解压
[hadoop@hadoop01 ~]$ cd sqoop-1.4.7.bin__hadoop-2.6.0
[hadoop@hadoop01 sqoop-1.4.7.bin__hadoop-2.6.0]$ ls -ll -查看目录

3.2 配置sqoop——mysql连接器：
下载mysql-connector-java-8.0.16.jar，并将其拷贝至sqoop安装目录下的lib文件夹里

3.3 配置sqoop环境变量：

[hadoop@hadoop01 sqoop-1.4.7.bin__hadoop-2.6.0]$ cd conf
[hadoop@hadoop01 conf]$ ls -ll
total 28
-rw-rw-r--. 1 hadoop hadoop 3895 Dec 19  2017 oraoop-site-template.xml
-rw-rw-r--. 1 hadoop hadoop 1404 Dec 19  2017 sqoop-env-template.cmd

-rw-rw-r--. 1 hadoop hadoop 6044 Dec 19  2017 sqoop-site.xml

3.3.1 拷贝复制sqoop-env.sh样本，并添加hadoop、hbase、hive、zookeeper的安装目录（注：没有的就不添加）

[hadoop@hadoop01 conf]$ cp sqoop-env-template.sh sqoop-env.sh
[hadoop@hadoop01 conf]$ gedit sqoop-env.sh
修改的内容：
#Set path to where bin/hadoop is available
export HADOOP_COMMON_HOME=/home/hadoop/hadoop-3.2.0

#Set path to where hadoop-*-core.jar is available
export HADOOP_MAPRED_HOME=/home/hadoop/hadoop-3.2.0

#set the path to where bin/hbase is available
export HBASE_HOME=/home/hadoop/hbase-2.2.1

#Set the path to where bin/hive is available
export HIVE_HOME=/home/hadoop/apache-hive-3.1.2-bin

#Set the path for where zookeper config dir is
export ZOOCFGDIR=/home/hadoop/apache-zookeeper-3.5.5

3.3.2 配置linux环境变量

[hadoop@hadoop01 conf]$ gedit ~/.bash_profile
[hadoop@hadoop01 conf]$ source ~/.bash_profile
新添加：
#sqoop
export SQOOP_HOME=/home/hadoop/sqoop-1.4.7.bin__hadoop-2.6.0
export PATH=$PATH:$SQOOP_HOME/bin

3.4 验证sqoop是否安装成功

[hadoop@hadoop01 sqoop-1.4.7.bin__hadoop-2.6.0]$ bin/sqoop help --执行该命令，看到如下信息就表示成功
Warning: /home/hadoop/sqoop-1.4.7.bin__hadoop-2.6.0/../hcatalog does not exist! HCatalog jobs will fail.
Please set $HCAT_HOME to the root of your HCatalog installation.
Warning: /home/hadoop/sqoop-1.4.7.bin__hadoop-2.6.0/../accumulo does not exist! Accumulo imports will fail.
Please set $ACCUMULO_HOME to the root of your Accumulo installation.

3.5 测试sqoop与mysql的连接
sqoop list-tables --username User --password 'User_123456' --connect jdbc:mysql://localhost:3306/hahive /**方式1**/
sqoop list-tables --username User -P --connect jdbc:mysql://localhost:3306/hahive  /**方式2**/
Enter password:

如果能执行以上操作，可以看见结果，说明sqoop能连接mysql。
