apache geode 试用

使用docker 运行,文档参考的官方的5 分钟学习文档

拉取镜像

docker pull apachegeode/geode

启动

docker run -it -p 10334:10334 -p 7575:7575 -p 1099:1099 -p 40404:40404  apachegeode/geode

初始化数据

容器内

start locator

start server

create region --name=hello --type=REPLICATE 

提示信息

create region --name=hello --type=REPLICATE 

     Member | Status

---------------- | ---------------------------------------------

fix-powerful-cup | Region "/hello" created on "fix-powerful-cup"

 

 

简单运行

因为使用了容器，同时我们需要配置一个简单hosts 别名

/etc/hosts

127.0.0.1 55bbae309e69
