kettle 作业配置

1. 1.在/usr/local/sbin 下新建新建kettle项目路径
2. 2.上传kettle作业文件，包含kjb文件和ktr文件，kjb文件引用ktr时，通过自定义变量配置文件路径
3. 3.添加kettle执行脚本
4. vi kettle.sh

5. #!/bin/bash
   #每天都要执行
   export JAVA_HOME=/usr/local/jdk1.8
   export JAVA_BIN=$JAVA_HOME/bin
   export JAVA_LIB=$JAVA_HOME/lib
   export PATH=$PATH:$HOME/bin:$JAVA_HOME/bin
   export CLASSPATH=.:$JAVA_LIB/tools.jar:$JAVA_LIB/dt.jar
   export KETTLE_HOME=/usr/local/src/data-integration
   #抽取微尘4.0数据到customize
   /usr/local/src/data-integration/kitchen.sh -file=/usr/local/sbin/kettle/customize/weichen_sync.kjb ­level=basic>>/var/log/kettle_log/weichen_sync.log

6. 4.给kettle.sh 文件增加可执行权限
7. chmod u+x kettle.sh

设置定时任务

1. 1.使用linux自带的crontab，添加定时任务,每天00:30执行脚本
2. crontab -e
3. `30 0 * * * * * /usr/local/sbin/kettle/kettle.sh`
4. 2.重新加载任务,若未启动状态，则执行`service crond start`命令启动
5. service crond reload
