datax如何编译安装

这篇文章主要介绍了datax如何编译安装，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。

1.centos系统maven安装参考https://www.cnblogs.com/laoayi/p/12867990.html

1.下载 官网地址: http://maven.apache.org/download.cgi

curl -O https://mirror.bit.edu.cn/apache/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz

2.解压

tar -zxvf apache-maven-3.6.3-bin.tar.gz

3.修改环境变量

vim /etc/profile

export MAVEN_HOME=/opt/maven/apache-maven-3.6.3
export PATH=$MAVEN_HOME/bin:$PATH

修改maven镜像地址

vim /opt/maven/apache-maven-3.6.3/conf/settings.xml

 添加如下代码：

     <mirror>
           <id>alimaven</id>
           <name>aliyun maven</name>
           <url>http://maven.aliyun.com/nexus/content/repositories/central/</url>
           <mirrorOf>central</mirrorOf>
     </mirror>

source /etc/profile //使用环境变量生效

4.查看是否成功安装

 mvn -version

[root@ambari-03 maven]#  mvn -version
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: /opt/maven/apache-maven-3.6.3
Java version: 1.8.0_181, vendor: Oracle Corporation, runtime: /usr/local/java/jdk/jdk1.8.0_181/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.10.0-957.el7.x86_64", arch: "amd64", family: "unix"

2.下载datax源码

安装git

yum install curl-devel expat-devel gettext-devel  openssl-devel zlib-devel

git --version //查看是否安装成功

git clone git@github.com:alibaba/DataX.git  //下载datax源码  权限失败需要登录用户

使用另一种curl方式下载源码

 curl -O https://gitee.com/jarynpl/DataX/repository/archive/master.zip

unzip master.zip //解压

3. 通过maven打包：

$ cd  {DataX_source_code_home}

$  mvn -U clean package assembly:assembly -Dmaven.test.skip=true

编译失败问题处理 ：网址https://github.com/alibaba/datax/issues/676

[ERROR] Failed to execute goal on project clickhousewriter: Could not resolve dependencies for project com.alibaba.datax:clickhousewriter:jar:0.0.1-SNAPSHOT: Could not find artifact com.alibaba.datax:simulator:jar:0.0.1-SNAPSHOT in alimaven (http://maven.aliyun.com/nexus/content/repositories/central/) -> [Help 1]

Clickhousewriter 存在问题，可以在该模块 pom.xml 文件中，注释掉该依赖(该依赖用作测试，代码里面也没有单元测试)

        <dependency>
            <groupId>com.alibaba.datax</groupId>
            <artifactId>simulator</artifactId>
            <version>${datax-project-version}</version>
            <scope>test</scope>
        </dependency>

另外，需要把 ClickhouseWriter.java 中 15行，引入的 ClickHouseType去掉，未识别该类

import ru.yandex.clickhouse.ClickHouseTuple;

然后尝试编译成功。

打包成功，日志显示如下：

[INFO] gdbwriter .......................................... SUCCESS [  2.537 s]
[INFO] cassandrawriter .................................... SUCCESS [  1.323 s]
[INFO] clickhousewriter ................................... SUCCESS [  1.416 s]
[INFO] hbase20xsqlreader .................................. SUCCESS [  5.429 s]

[INFO] Total time:  04:07 min
[INFO] Finished at: 2021-01-22T19:24:49+08:00
[INFO] ------------------------------------------------------------------------

打包成功后的DataX包位于 {DataX_source_code_home}/target/datax/datax/ ，

结构如下：

$ cd  {DataX_source_code_home}
$ ls ./target/datax/datax/
bin		conf		job		lib		log		log_perf	plugin		script		tmp
