Apr 2012 12:30:08 +0800 https://ruby-china.org/topics/2677 https://ruby-china.org/topics/2677 <p>最近在自己廉价的 VPS（内存只有 512M）上部署 Ruby China 应用，运行 solr 需要 Java 运行环境，安装好 openjdk-6-jre 后执行 rake sunspot:solr:start 可以运行 solr。但是<strong>一分钟左右就自动退出了</strong>，我怀疑是内存不足或者是 Java 版本问题。我就删除 openjdk-6-jre 后安装了 sun-java5-jdk，结果还是一分钟左右就自动退出。 问一下大家，是不是我的 Java 配置有问题？还是我的内存太小了？ </p> yetone Tue, 17 Apr 2012

virtual machine. 估计应该是内存不足。我是典型的无产阶级——普通学生一枚，没有多少钱买高配置，希望和他人合租的 vps。 要求就是能把 Java virtual machine 稳定地运行下来，主要是自己搭建个 Ruby China 的 ror 应用。 </p> yetone Mon, 16 Apr 2012 22:18:53 +0800
