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
