Question

我正在尝试在openshift中启动一个播放项目。第一阶段即项目的近15％已成功完成并上传。所以，我猜初始配置还可以。现在，在我完成了项目的其余部分之后，当我尝试使用ssh推送项目时，每次在一定时间后，远程服务器挂起并显示以下消息。

remote: [info] Done packaging.
remote: model contains 69 documentable templates
Connection to blogofprime-thatsqt.rhcloud.com closed by remote host.
fatal: The remote end hung up unexpectedly
error: error in sideband demultiplexer
To ssh://5455ef32e0b8cd379e000293@blogofprime-thatsqt.rhcloud.com/~/git/blogofprime.git/
 + 557ec12...4034b71 HEAD -> master (forced update)

远程服务器挂起后，每次都会发生这种情况。

我的openshift.conf文件：

# This is the main configuration file for the application.
# ~~~~~

include "application"

# Secret key
# ~~~~~
# The secret key is used to secure cryptographics functions.
# If you deploy your application to several instances be sure to use the same key!
application.secret="V0sLX<RAciXw_>7^O8y=I4BRW/M4@vhVhF=H44`lMfgAV2hs^Pp?tsfroKt1J3eX"

# The application languages
# ~~~~~
application.langs="en"

# Database configuration
# ~~~~~ 
# You can declare as many datasources as you want.
# By convention, the default datasource is named `default`
#

db.default.driver=com.mysql.jdbc.Driver
db.default.url="jdbc:mysql://"${OPENSHIFT_MYSQL_DB_HOST}":"${OPENSHIFT_MYSQL_DB_PORT}"/"${OPENSHIFT_APP_NAME}
db.default.user=${OPENSHIFT_MYSQL_DB_USERNAME}
db.default.password=${OPENSHIFT_MYSQL_DB_PASSWORD}

# Evolutions
# ~~~~~
# You can disable evolutions if needed
# evolutionplugin=disabled

# Ebean configuration
# ~~~~~
# You can declare as many Ebean servers as you want.
# By convention, the default server is named `default`
#
ebean.default="models.*"


# Logger
# ~~~~~
# You can also configure logback (http://logback.qos.ch/), by providing a logger.xml file in the conf directory .

# Root logger:
logger.root=ERROR

# Logger used by the framework:
logger.play=INFO

# Logger provided to your application:
logger.application=DEBUG

我的build.sbt文件：

name := "thatsqt"

version := "1.0-SNAPSHOT"

scalaVersion := "2.11.2" // or "2.10.4"

libraryDependencies ++= Seq(
  // Select Play modules
  jdbc,      // The JDBC connection pool and the play.api.db API
  //anorm,     // Scala RDBMS Library
  javaJdbc,  // Java database API
  javaEbean, // Java Ebean plugin
  javaJpa,   // Java JPA plugin
  filters,   // A set of built-in filters
  javaCore,  // The core Java API
  // WebJars pull in client-side web librarie
  "org.webjars" %% "webjars-play" % "2.3.0",
  "com.typesafe.play" %% "play-slick" % "0.8.0",
  // Add your own project dependencies in the form:
  // "group" % "artifact" % "version"
  "mysql" % "mysql-connector-java" % "5.1.27"
)

fork in Test := false

lazy val root = (project in file(".")).enablePlugins(PlayJava)

EclipseKeys.withSource := true

平台：我正在使用Mac OS X和类型安全激活器来播放框架。

我尝试了什么：我试着在服务器和客户端unset TMOUT。此时我不太确定这是否是超时问题或其他问题。

我该如何解决这个问题？

Answer 1

如果问题最近开始发生，可能是超出配额造成的。使用1GB小齿轮耗尽空间是很常见的。

尝试使用rhc app-tidy rhc命令：

rhc app-tidy <app>

Answer 2

您的项目是否包含大型二进制文件？这可能会导致git占用大量的RAM服务器端，而一个小的Openshift设备会占用占用太多RAM的东西。解决方案是ssh进入你的Openshift框（使用＆＃34; rhc ssh＆＃34;或等效的）并告诉服务器端git限制其RAM使用：

cd git/*.git
git config pack.windowMemory "25m"
git config pack.packSizeLimit "25m"
git config pack.threads "1"

为什么他们默认不这样做我不知道。

另外，下次要将大型二进制文件放入项目时，您不必将它们检入git存储库（这将占用跟踪其整个历史记录的空间）：你可以只是指示你的应用程序根据需要从另一台服务器下载它们（第二台服务器只需要能够托管静态文件）。
