环境下载
首先将下载的 sqoop-1.4.6.bin__hadoop-2.0.4-alpha.tar.gz放到 /usr/hadoop/目录下（该目录可以自定义，一般为Hadoop集群安装目录），然后对安装包解压、修改文件名和修改用户权限。
[hadoop@centpy /]$ cd /usr/hadoop/ [hadoop@centpy hadoop]$ ls flume hadoop-2.6.0 [hadoop@centpy hadoop]$ rz //上传安装包 [hadoop@centpy hadoop]$ ls flume hadoop-2.6.0 sqoop-1.4.6.bin__hadoop-2.0.4-alpha.tar.gz [hadoop@centpy hadoop]$ tar -zxf sqoop-1.4.6.bin__hadoop-2.0.4-alpha.tar.gz //解压 [hadoop@centpy hadoop]$ mv sqoop-1.4.6.bin__hadoop-2.0.4-alpha sqoop //修改安装文件目录 [hadoop@centpy hadoop]$ ls flume hadoop-2.6.0 sqoop sqoop-1.4.6.bin__hadoop-2.0.4-alpha.tar.gz [hadoop@centpy hadoop]$ rm -f sqoop-1.4.6.bin__hadoop-2.0.4-alpha.tar.gz //删除安装包 [hadoop@centpy hadoop]$ ls flume hadoop-2.6.0 sqoop
环境配置
1.配置hadoop版本号
切换到/sqoop/conf 目录下，执行以下命令修改对应Hadoop版本号为自己所安装的集群的版本号。
[hadoop@centpy hadoop]$ cd sqoop/
[hadoop@centpy sqoop]$ ls
bin COMPILING.txt ivy LICENSE.txt README.txt sqoop-test-1.4.6.jar
build.xml conf ivy.xml NOTICE.txt sqoop-1.4.6.jar src
CHANGELOG.txt docs lib pom-old.xml sqoop-patch-review.py testdata
[hadoop@centpy sqoop]$ vi build.xml
修改为：
2.配置sqoop-env.sh文件
执行以下命令生成sqoop-env.sh配置文件。
[hadoop@centpy sqoop]$ cd conf/ [hadoop@centpy conf]$ ls oraoop-site-template.xml sqoop-env-template.sh sqoop-site.xml sqoop-env-template.cmd sqoop-site-template.xml [hadoop@centpy conf]$ mv sqoop-env-template.sh sqoop-env.sh
然后使用 vi sqoop-env.sh 命令，打开文件添加如下内容。
如果数据读取不涉及hbase和hive，那么相关hbase和hive的配置可以不加；如果集群有独立的zookeeper集群，那么配置zookeeper，反之，不用配置。
3.配置环境变量
[hadoop@centpy conf]$ su Password: [root@centpy conf]# vim /etc/profile //追加以下内容 #sqoop export SQOOP_HOME=/usr/hadoop/sqoop export PATH=$PATH:$SQOOP_HOME/bin [root@centpy conf]# source /etc/profile
4.上传jar包
将相关的驱动 jar 包拷贝到 sqoop/lib 目录下。数据库驱动 jar 包需要导入，这里我们使用的是 mysql 数据库，所以需要导入mysql-connector-java-5.1.32.jar包。
5.确定用户组
需要确定sqoop所属用户组是否为hadoop
[hadoop@centpy hadoop]$ ll total 12 drwxrwxr-x. 9 hadoop hadoop 4096 Jun 19 15:30 flume drwxr-xr-x. 12 hadoop hadoop 4096 Jun 13 21:14 hadoop-2.6.0 drwxr-xr-x. 9 hadoop hadoop 4096 Jun 21 09:56 sqoop
如果不是请通过以下语句修改：
chown –R hadoop:hadoop sqoop
测试运行
//首先启动hadoop集群
[hadoop@centpy sqoop]$ cd ../hadoop-2.6.0/ [hadoop@centpy hadoop-2.6.0]$ sbin/start-all.sh This script is Deprecated.

sqoop 命令执行成功，代表安装成功。
sqoop list-databases --connect jdbc:mysql://202.193.60.117/dataweb --username root --password 20134997
该语句中使用我们上传的mysql-connector-java-5.1.32.jar包链接本地数据库，其中ip地址可以通过命令行中输入ipconfig进行查看。
执行该命令之前要先启动数据库服务，若出现2003错误时因为mysql服务没有成功启动，解决方案如下：
选中后右键开启服务即可。
到此，sqoop的安装和配置就结束了！
