无法在服务器 CentOS 7 上 运行 h2o.init()
Can't run h2o.init() on server CentOS 7
我在装有 CentOs 7 的服务器上使用 R 中的 h2o 包。
我正确安装了库。 Java版本
java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)
正确设置为 JAVA_HOME。
当我 运行 h2o.init() 时，我收到了一条错误的长消息

所以我设法 运行。我去了
/home/datascience/.checkpoint/2018-11-20/lib/x86_64-redhat-linux-gnu/3.5.1/h2o/java
and 运行 java -jar h2o.jar 并且我在端口 54323 下找到实例 运行ning。
然后我回到 R 和 运行
h2o.init(ip='machine_ip',port=54321,max_mem_size='2g',startH2O=FALSE)
它奏效了。但为什么？？我关闭一切，重新打开它，唯一能让事情正常进行的是 运行 java -jar h2o.jar 然后转到 R 会话和 运行 h2o.init()
h2o.init() 将查找现有的 h2o 实例。因为你用“java -jar h2o.jar”手工开始一个 h2o.init() 找到它并连接到它。
如果您没有指定 IP 地址，并且 h2o.init() 没有找到 h2o 实例 运行，那么 h2o.init() 将尝试创建一个，如果startH2O 为真。消息说端口 54321 或端口 54322 不可用正是这个意思。其中一个必须已经被采取，即使它不是你想要的。使用“netstat -anp”诊断 linux.
上的端口使用情况
好的，我找到了一个在我公司工作的软件工程师的解决方案。
他简单地写了一个 bash 将调用 "java -jar h2o.jar" 手动启动 h2o 集群，在 R 脚本中我通过
连接到现有的 h2o 实例
h2o.init(ip="machine_ip",port=number_port,startH2O=FALSE)
我在装有 CentOs 7 的服务器上使用 R 中的 h2o 包。
我正确安装了库。 Java版本
