ubuntu下安装jython, elasticsearch

jython安装

1. sudo apt-get install jython

2. 因为我之前已经安装过java,所以这里就直接可以了, 如果没有的可能需要安装java虚拟机,如下;

3. http://www.linuxdiyf.com/linux/16260.html

4. .profile文件最后加入:

#pig path
export PATH=$PATH:/usr/local/hadoop/pig/bin

5. pig -x local 测试OK

elasticsearch安装

1. 官网下载版本: https://www.elastic.co/downloads/elasticsearch

2. tar -zvxf elasticsearch-5.0.0.tar.gz

3. mv elasticsearch-5.0.0 elasticsearch

4. mv elasticsearch /use/local/hadoop

5. 进入elasticsearch目录

6. /bin/elasticsearch

7. 如果出现错误:

Exception in thread "main" java.lang.RuntimeException: don‘t run elasticsearch as root.
at org.elasticsearch.bootstrap.Bootstrap.initializeNatives(Bootstrap.java:93)

....

则参照文章:

.bashrc里面添加:

JAVA_HOME=/usr/java/jdk1.7.0_72
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:$CLASSPATH
PATH=$JAVA_HOME/bin:$PATH

上面的/usr/java/jdk1.7.0_72 根据你自己的情况写进去, 这个路径通过下面的命令来查看:

update-alternatives --config java
