apache atlas项目搭建（1.0.0，2.0.0），centos7环境

1、jdk1.8、maven3、nodejs

jdk、maven解压、配置环境变量；

nodejs安装，参考 https://www.cnblogs.com/jizhong/p/12102100.html

centos7自带python2.7.5，无需安装

2、配置环境变量 /etc/profile

JAVA_HOME=/usr/local/tools/jdk1.8.0_161
export export PATH=${JAVA_HOME}/bin:${PATH}
MAVEN_HOME=/usr/local/tools/apache-maven-3.6.3
export PATH=${MAVEN_HOME}/bin:${PATH}
NODE_HOME=/usr/local/tools/node
export PATH=${NODE_HOME}/bin:${PATH}
配置生效 source /etc/profile
3、查看版本信息：
node -v
v6.12.3
npm -v
3.10.10
python -V
Python 2.7.5
java -version
mvn –v
4、使用淘宝的npm镜像cnpm
npm install -g cnpm --registry=https://registry.npm.taobao.org
5、maven 配置文件（阿里镜像、仓库地址、jdk版本）
替换maven源，阿里云的源
打开maven配置文件 settings.xml
<mirror>
    <id>alimaven</id>
    <name>aliyun maven</name>
    <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
    <mirrorOf>central</mirrorOf>
</mirror>
指定下载资源位置
<localRepository>/usr/local/maven/repository</localRepository>
指定jdk版本（本座没有配置）
<profile>    
    <id>jdk-1.8</id>    
    <activation>    
        <activeByDefault>true</activeByDefault>    
        <jdk>1.8</jdk>    
    </activation>    
    <properties>    
        <maven.compiler.source>1.8</maven.compiler.source>    
        <maven.compiler.target>1.8</maven.compiler.target>    
        <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>    
    </properties>
</profile>
二、apache atlas1.0.0
1、下载源系统 http://atlas.apache.org/#/Downloads
1）、该方式编译不会内嵌HBase和Solr
mvn clean -DskipTests package -Pdist
2）、使用atlas内嵌HBase和Solr，测试用这种方式，注意：embedded-hbase-solr前面没有空格
mvn clean -DskipTests package -Pdist,embedded-hbase-solr
编译完成后的jar包位于目录：\apache-atlas-sources-1.1.0\distro\target 中，压缩包有对应的解压文件，可直接部署；或者自己加压到指定路径
3、部署，进入 apache-atlas-1.0.0 路径
/usr/local/projects/apache-atlas-sources-1.0.0/distro/target/apache-atlas-1.0.0-bin/apache-atlas-1.0.0
用内嵌的 hbase 和 solr 启动，配置hbase和solr跟随atlas启动和停止
export MANAGE_LOCAL_HBASE=true
export MANAGE_LOCAL_SOLR=true
上面的两步已经在 atlas-env.sh 文件默认配置
bin/atlas_start.py
5、查看进程 jps
6、添加自带例子 bin/quick_start.py
Enter username for atlas :- admin Enter password for atlas :- admin
7、管理界面登录入口 http://localhost:21000 用户名：admin 密码：admin
8、停止atlas，bin/atlas_stop.py
在hbase里配置了JAVE_HOME
三、apache atlas2.0.0
编译过程和1.0.0一致，编译时间较1.0更长
编译完成后使用
/usr/local/project/apache-atlas-sources-2.0.0/distro/target/apache-atlas-2.0.0-server/apache-atlas-2.0.0
1、修改配置文件 apache-atlas-2.0.0-server/apache-atlas-2.0.0/conf/
vim atlas-env.sh
export JAVA_HOME=/usr/local/tools/jdk1.8.0_161
export MANAGE_LOCAL_HBASE=true  #如果要使用外部的zk和hbase，则改为false
export MANAGE_LOCAL_SOLR=true  #如果要是用外部的solr，则改为false
vim atlas-application.properties
# Hbase地址（对应的zk地址）配置（自带hbase会根据此端口启动一个zk实例）
atlas.graph.storage.hostname=localhost:2181 # 如果使用外部hbase，则填写外部zookeeper地址
# Solr地址配置
atlas.graph.index.search.solr.http-urls=http://localhost:8984/solr
# Kafka相关配置
atlas.notification.embedded=true # 如果要使用外部的kafka，则改为false
# 内嵌kafka会根据此端口启动一个zk实例
atlas.kafka.zookeeper.connect=localhost:9026 # 如果使用外部kafka，则填写外部zookeeper地址
atlas.kafka.bootstrap.servers=localhost:9027 # 如果使用外部kafka，则填写外部broker server地址
2、手动启动hbase
# 进入atlas自带的hbase目录
apache-atlas-2.0.0-server/apache-atlas-2.0.0/hbase 
# 启动 hbase 
bin/start-hbase.sh
3、手动启动solr，为solr创建初始化index库
# 进入atlas自带的solr目录，
apache-atlas-2.0.0-server/apache-atlas-2.0.0/solr
# 启动solr
bin/solr start -c -z localhost:2181 -p 8984 -force
# 创建初始化collections
bin/solr create -c vertex_index -shards 1 -replicationFactor 1 -force
bin/solr create -c edge_index -shards 1 -replicationFactor 1 -force
bin/solr create -c fulltext_index -shards 1 -replicationFactor 1 -force
然后打开浏览器访问solr的web服务如下，则solr启动成功 http://localhost:8984/
4、启动atlas，apache-atlas-2.0.0-server/apache-atlas-2.0.0
bin/atlas_start.py
最后添加自带例子，同1.0.0
四、访问路径
atlas：http://192.168.198.129:21000/
solr(1.0.0)：http://192.168.65.139:9838/
solr(2.0.0)：http://localhost:8984/

编译错误：
晚上下班突然就可以了

需要安装nodejs，并使用淘宝的npm镜像cnpm
npm install -g cnpm --registry=https://registry.npm.taobao.org

solr启动失败，还是配置的问题
hbase Error: JAVA_HOME is not set
/usr/local/project/apache-atlas-sources-2.0.0/distro/target/apache-atlas-2.0.0-bin/apache-atlas-2.0.0/hbase/conf
atlas 1.0.0 配置了JAVA_HOME
hbase-env.sh
cannot create temp file for here-document: No space left on device
空间满了 df -h
