接上一篇在本机用windows 跑kettle迁移，鉴于其中一张表每天增量200W左右，本地迁移速度太慢，加上vpn连接服务器不稳定经常断，kettle并不支持断点续传，决定把windows上的kettle配置放在linux环境上跑。
一：linux安装jdk
参考：https://www.cnblogs.com/nothingonyou/p/11936850.html
二：liunx部署kettle
kettle是直接部署在了要转换的mysql服务器上，避免了中间的传输网络消耗，把windows下已解压的文件，压缩后上传至linux相关目录，如图：
1.建立kettle目录，并解压文件
[root@localhost opt]# mkdir kettle
[root@localhost opt]# mv data-integration.zip kettle/
[root@localhost opt]# cd kettle
[root@localhost kettle]# unzip data-integration.zip
[root@localhost kettle]# rm -rf data-integration.zip
[root@localhost kettle]# cd data-integration/
[root@localhost data-integration]# chmod +x *.sh
2.测试是否安装成功
[root@localhost /]# cd /opt/kettle/data-integration/
[root@localhost data-integration]# ./kitchen.sh
出现下面信息，表明安装成功：
[root@localhost data-integration]# ./kitchen.sh

Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=51200m; support was removed in 8.0
Options:
-rep = Repository name
-user = Repository username
-pass = Repository password
-job = The name of the job to launch
-dir = The directory (dont forget the leading /)
-file = The filename (Job XML) to launch
-level = The logging level (Basic, Detailed, Debug, Rowlevel, Error, Minimal, Nothing)
-logfile = The logging file to write to
-listdir = List the directories in the repository
-listjobs = List the jobs in the specified directory
-listrep = List the available repositories
-norep = Do not log into the repository
-version = show the version, revision and build date
-param = Set a named parameter <NAME>=<VALUE>. For example -param:FILE=customers.csv
-listparam = List information concerning the defined parameters in the specified job.
-export = Exports all linked resources of the specified job. The argument is the name of a ZIP file.
-custom = Set a custom plugin specific option as a String value in the job using <NAME>=<Value>, for example: -custom:COLOR=Red
-maxloglines = The maximum number of log lines that are kept internally by Kettle. Set to 0 to keep all rows (default)
-maxlogtimeout = The maximum age (in minutes) of a log line while being kept internally by Kettle. Set to 0 to keep all rows indefinitely (default)
备注：
kitchen.sh：用来执行job作业
pan.sh：用来执行ktr转换
三：脚本调用kettle程序
1.创建kettle工作目录
[root@localhost opt]# mkdir -p /opt/kettle/kettle_file/job
[root@localhost opt]# mkdir -p /opt/kettle/kettle_file/transition
[root@localhost opt]# mkdir -p /opt/kettle/kettle_sh
[root@localhost opt]# mkdir -p /opt/kettle/kettle_log
2.在/opt/kettle/kettle_sh目录下创建执行文件vim o2m.sh
#!/bin/sh
cd /opt/kettle/data-integration/
export JAVA_HOME=/opt/apps/java/jdk1.8.0_191
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
./pan.sh -file=/opt/kettle/kettle_file/transition/o2m.ktr >>/opt/kettle/kettle_log/o2m_$(date +%Y%m%d).log &
3.修改执行权限
chmod +x o2m.sh
4.配置好windows 的ktr文件，测试成功后上传至linux对应的目录transition下
5.linux上oracle和mysql的驱动目录和windows不一样，放在：
/opt/kettle/data-integration/libswt/linux/x86_64
[root@localhost x86_64]# pwd
/opt/kettle/data-integration/libswt/linux/x86_64
[root@localhost x86_64]# ll
总用量 7444
-rw-r--r--. 1 root root 992808 11月 26 09:03 mysql-connector-java-5.1.41-bin.jar
-rw-r--r--. 1 root root 2001778 11月 26 09:03 mysql-connector-java-6.0.6.jar
-rw-r--r--. 1 root root 2739670 11月 26 09:04 ojdbc6.jar
-rw-r--r--. 1 root root 1880133 5月 16 2017 swt.jar
6.执行sh脚本文件
./o2m.sh &
7.查看log观察转换情况：
[root@localhost kettle_log]# tail -20f 1127_20191128.log
2019/11/28 14:55:26 - 表输出.4 - 完成处理 (I=0, O=510558, R=510558, W=510558, U=0, E=0)

可以看到，400W+的数据只用了3分钟不到便完成了转换，速度得到了大大提升。
