條件 1.啓動mysql service mysqld start 2.啓動hadoop集羣 start-all.shjava
1.下載jar包(:http://mirrors.hust.edu.cn/apache/sqoop/1.4.6/)mysql
2.上傳安裝包sqoop-1.4.6.bin__hadoop-2.0.4-alpha.tar.gz到/root/目錄下sql
3.解壓數據庫
tar -zxvf sqoop-1.4.6.bin__hadoop-2.0.4-alpha.tar.gz -C /usr/local/
3.重命名配置文件apache
在/usr/local/sqoop-1.4.6.bin__hadoop-2.0.4-alpha/conf/oop
template表明臨時文件測試
mv sqoop-env-template.sh sqoop-env.sh mv sqoop-site-template.xml sqoop-site.xml (sqoop-site.xml若是存在的話就不用修改了)
4.修改配置文件 (根據本身狀況進行修改)lua
vi sqoop-env.shspa
export HADOOP_COMMON_HOME= /usr/local/hadoop-2.7.3 export HADOOP_MAPRED_HOME= /usr/local/hadoop-2.7.3 export HIVE_HOME= /usr/local/hive-2.3.4 export ZOOKEEPER_HOME= /usr/local/zookeeper-3.4.10 export ZOOCFGDIR= /usr/local/zookeeper-3.4.10/conf
5.拷貝jdbc驅動code
將 mysql-connector-java-5.1.37/mysql-connector-java-8.0.11.jar 放到 sqoop的lib目錄下哦
6.配置sqoop的環境變量
vi /etc/profile
記得更新 source /etc/profile
7.驗證sqoop(能夠省略)
咱們能夠經過某一個command來驗證sqoop配置是否正確:
$ bin/sqoop help 出現一些Warning警告(警告信息已省略),並伴隨着幫助命令的輸出: Available commands: codegen Generate code to interact with database records create-hive-table Import a table definition into Hive eval Evaluate a SQL statement and display the results export Export an HDFS directory to a database table help List available commands import Import a table from a database to HDFS import-all-tables Import tables from a database to HDFS version Display version information ·····
8.測試sqoop是否可以成功鏈接數據庫
mysql-connector-java-5.1.37
192.168.159.110 寫本身的ip test1 寫本身的鏈接
sqoop-list-database -connect jdbc:mysql://192.168.159.110:3306/test1 --username root --password 12345
mysql-connector-java-8.0.11.jar
sqoop-list-database --connect jdbc:mysql://192.168.150.110:3306/test1?serverTimezone=Asia/Shanghai --username root --password 123456
界面
出現以下輸出:
information_schema
metastore
mysql
performance_schema
錯誤:
錯誤緣由:mysql沒有受權登陸
解決方法:
1.登陸mysql mysql -uroot -p
2.use mysql;
3.更新域屬性
update user set host='%' where user='root';
4.執行以上語句後在進行更新語句
FLUSH PRIVILEGES;
5.執行受權語句
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'WITH GRANT OPTION;
6.退出 exit;
7.再次登陸 mysql -uroot -p
