使用shell腳本啟動akka程序，參考于GearPump項目

準(zhǔn)備工作：
便于測試修改，直接運行編譯出的class來啟動。在根目錄下創(chuàng)建bin目錄放shell腳本，創(chuàng)建lib放置依賴的jar包。安裝JDK

腳本內(nèi)容：

    #!/bin/sh
    if [ -z "$PROG_HOME" ] ; then
      ## resolve links - $0 may be a link to PROG_HOME
      PRG="$0"

      # need this for relative symlinks
      while [ -h "$PRG" ] ; do
        ls=`ls -ld "$PRG"`
        link=`expr "$ls" : '.*-> \(.*\)$'`
        if expr "$link" : '/.*' > /dev/null; then
          PRG="$link"
        else
          PRG="`dirname "$PRG"`/$link"
        fi
      done

      saveddir=`pwd`

      PROG_HOME=`dirname "$PRG"`/..

      # make it fully qualified
      PROG_HOME=`cd "$PROG_HOME" && pwd`

    cd "$saveddir"
   fi

  #配置jdk目錄
  JAVACMD="/usr/jdk1.8.0_181/bin/java"
  JAVA_HOME="/usr/jdk1.8.0_181/"
  if [ ! -x "$JAVACMD" ] ; then
    echo "Error: JAVA_HOME is not defined correctly."
    echo "  We cannot execute $JAVACMD"
    exit 1
  fi

  if [ -z "$JAVA_HOME" ] ; then
    echo "Warning: JAVA_HOME environment variable is not set."
  fi

  CLASSPATH_SUFFIX=""
  # Path separator used in EXTRA_CLASSPATH
  PSEP=":"

  echo $@

  PROG_NAME=master
  PROG_VERSION=0.8.5-SNAPSHOT


  
  exec "$JAVACMD" \
   "-server" "-Djava.net.preferIPv4Stack=true" "-DlogFilename=master" "-Djava.rmi.server.hostname=localhost" \
 ${JAVA_OPTS} \
 -cp "${PROG_HOME}/conf${PSEP}${PROG_HOME}/lib/*${PSEP}${PROG_HOME}/target/scala-2.11/classes"\
 com.mango.sharding.main.Master "$@"

啟動腳本 根目錄下 bin/XXX 可以帶參數(shù)
例如 bin/master -ip 0.0.0.0 -port 0
在Master 中 處理參數(shù)

    object Master{
      def  main(args: Array[String]): Unit = {}
    }
    // args: Array("-ip","0.0.0.0","-port","0")

• 注：把scala-library-X.X.X.jar放入\lib\
