Shulou(Shulou.com)06/01 Report--

Recently, I was studying the open source in-memory database, and apache ignite used it for some time to feel that it was okay because there was too little data, so I just used its rpc function to build a distributed framework.

The apache geode framework was discovered the day before yesterday, which is said to be the open source version of Gemfire 12306.

Official website address: http://geode.apache.org/

I. installation

Before installation, jdk (preferably jdk1.8) must be installed on the server and JAVA_HOME must be configured.

download

Wget http://mirrors.tuna.tsinghua.edu.cn/apache/geode/1.2.1/apache-geode-1.2.1.tar.gztar-zxvf apache-geode-1.2.1.tar.gz-C / opt/cd / opt/apache-geode-1.2.1/

Add bin to PATH

Vi / etc/profile

Add on the last line

Export PATH=$PATH:/opt/apache-geode-1.2.1/bin

Make the environment variable effective

Source / etc/profile

Test whether the installation is successful

Starting locator,locator I understand that similar to a request forwarder is responsible for forwarding various queries to each server. The default port is: 10334

[root@master] # gfsh _ / _ _ / / _ / _ / / / 1.2.1Monitor and Manage Apache Geodegfsh > gfsh > start locator-- name=locator50

Start server

Gfsh > start server--name=server50-- server-port=40411

Check the cluster. There is only one.

Gfsh > list members Name | Id- |-locator50 | 192.168.60.50 (locator50:32148:locator): 1024server50 | 192.168.60.50 (server50:32411): 1025

Third, try the command line

Please refer to the document: http://geode.apache.org/docs/guide/12/getting_started/15_minute_quickstart_gfsh.html

Region can think of tables in the database

Create region-name=regionA-type=REPLICATE_PERSISTENT

3.2 View region list

Gfsh > list regionsList of regions-regionA

Insert two pieces of kv data

Gfsh > put-region=regionA-key= "1"-value= "one" Result: trueKey Class: java.lang.StringKey: 1Value Class: java.lang.StringOld Value: gfsh > put-region=regionA-key= "2"-value= "two" Result: trueKey Class: java.lang.StringKey: 2Value Class: java.lang.StringOld Value:

3.4 query data

Gfsh > query-- query= "select * from / regionA" Result: trueLimit: 100Rows: 2Result-twoone
