kettle在centos7.x上的安装教程

• 环境说明

 Linux：Centos7.6最小化安装

JDK：1.8.202

Kettle：7.1

•  安装JDK

1、下载Linux下的jdk文件，本例使用的是jdk-8u202-linux-x64.tar.gz 百度云 官网

2、解压：tar -zxvf jdk-8u202-linux-x64.tar.gz -C /usr/local/java

3、配置环境变量：vim /etc/profile 在最后增加：

export JAVA_HOME=/usr/local/java/jdk1.8.0_202
export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
export PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin

4、其中JAVA_HOME为jdk解压后的路径，修改后执行：source /etc/profile  使配置生效

5、检测jdk安装：java -version   --出现java的版本信息，jdk安装成功

•  kettle安装

1、下载kettle7.1：百度云  官网

2、下载后为zip文件:pdi-ce-7.1.0.0-12.zip,解压：unzip pdi-ce-7.1.0.0-12.zip --注可能需要安装unzip：yum install -y unzip

3、解压后得到新文件夹：data-integration，进入并执行命令：chmod +x *.sh  --给sh脚本增加执行权限

4、在data-integration文件下执行：./kitchen.sh --如果出现帮助信息则成功

5、如果出现警告信息

#######################################################################
WARNING:  no libwebkitgtk-1.0 detected, some features will be unavailable
    Consider installing the package with apt-get or yum.
    e.g. 'sudo apt-get install libwebkitgtk-1.0-0'
#######################################################################

   直接安装：yum install -y webkitgtk  --会报错提示No package webkitgtk available,x需要先进行如下操作：

    1）下载最新的nux-dextop-release rpm包，百度网盘  官方

    2）先安装epel ： yum install -y epel-release

    3）在该rpm文件所在目录执行：rpm -Uvh nux-dextop-release-0-1.el7.nux.noarch.rpm

    4）安装webkitgtk：yum install -有webkitgtk 

    5）安装成功后再执行:./kitchen.sh, 警告消失。

6、可能会报错(我没遇到啊)

2018/09/28 11:10:01 - org.pentaho.di.ui.util.EnvironmentUtils@6482eef - ERROR (version 7.1.0.0-12, build 1 from 2017-05-16 17.18.02 by buildguy) : java.io.IOException: Cannot run program "lsb_release": error=2, 没有那个文件或目录

2018/09/28 11:10:01 - org.pentaho.di.ui.util.EnvironmentUtils@6482eef - at java.lang.ProcessBuilder.start(ProcessBuilder.j

  该报错可以通过： yum install -y redhat-lsb 来解决
