我是采用的源码编译的包安装的， 主要是考虑到会对部分功能做裁剪或增强， 具体源码编译方式可以参考另外一篇博文《编译Sqoop2错误解决》。然后从dist/target目录下拷贝sqoop-1.99.3.tar.gz压缩包的内容到/usr/lib/sqoop目录中。
接下来便是开始对相关配置文件进行配置，注意sqoop2是区分了server和client端的，我们首先安装服务端，记得服务端需要安装到可以执行hadoop命令行的机器上，最直接的方式就是安装到hadoop集群某个节点上，而客户端可以在任何机器上，只要能与sqoop server进行通信的机器就行。
1、服务端安装配置
进入/usr/lib/sqoop/server/conf目录，可以看到里面有几个配置文件， 有关于tomcat容器的还有sqoop本身的，首先我们配置catilina.properties，需要将hadoop的jar包依赖进来，当然，如果还需要导入hive或hbase，对应的jar包也需要照这样加入：
common.loader=${catalina.base}/lib,${catalina.base}/lib/*.jar,${catalina.home}/lib,${catalina.home}/lib/*.jar,${catalina.home}/../lib/*.jar,/home/cdh/hadoop-2.3.0-cdh5.1.2/share/hadoop/common/*.jar,/home/cdh/hadoop-2.3.0-cdh5.1.2/share/hadoop/common/lib/*.jar,/home/cdh/hadoop-2.3.0-cdh5.1.2/share/hadoop/hdfs/*.jar,/home/cdh/hadoop-2.3.0-cdh5.1.2/share/hadoop/hdfs/lib/*.jar,/home/cdh/hadoop-2.3.0-cdh5.1.2/share/hadoop/mapreduce/*.jar,/home/cdh/hadoop-2.3.0-cdh5.1.2/share/hadoop/mapreduce/lib/*.jar,/home/cdh/hadoop-2.3.0-cdh5.1.2/share/hadoop/tools/*.jar,/home/cdh/hadoop-2.3.0-cdh5.1.2/share/hadoop/tools/lib/*.jar,/home/cdh/hadoop-2.3.0-cdh5.1.2/share/hadoop/yarn/*.jar,/home/cdh/hadoop-2.3.0-cdh5.1.2/share/hadoop/yarn/lib/*.jar<pre name="code" class="html"># JDBC repository provider configuration org.apache.sqoop.repository.jdbc.handler=org.apache.sqoop.repository.derby.DerbyRepositoryHandler org.apache.sqoop.repository.jdbc.transaction.isolation=READ_COMMITTED org.apache.sqoop.repository.jdbc.maximum.connections=10 org.apache.sqoop.repository.jdbc.url=jdbc:derby:@BASEDIR@/repository/SQOOP;create=true org.apache.sqoop.repository.jdbc.driver=org.apache.derby.jdbc.EmbeddedDriver org.apache.sqoop.repository.jdbc.user=sa org.apache.sqoop.repository.jdbc.password=
# # Configuration for Mapreduce submission engine (applicable if it's configured) # # Hadoop configuration directory org.apache.sqoop.submission.engine.mapreduce.configuration.directory=/home/cdh/hadoop/etc/hadoop/另外配置暂时不用怎么特殊配置，保持默认就行， 如果需要可以进一步特殊配置即可， 毕竟先玩起来是要事！
最后需要做的一件事情就是将mysql-connector-java-5.1.20.jar这个MySQL驱动放入/usr/lib/sqoop/server/lib目录下：
最后便是启动服务端(我是安装到192.168.69.16):
/usr/lib/sqoop/bin/sqoop.sh server start
而作为客户端不需要任何配置，直接将压缩分发包发送到相应机器上解压，执行 bin/sqoop.sh client即可进入shell命令行界面，具体使用可以参考官方文档：
遗留问题， 启动老是报一个错误，应该是日志jar冲突导致的，一直没搞定，如果有知道如何处理的，可以一起交流哈：
