Question

我已安装并尝试在我的虚拟机上启动Cassandra 2.0服务。

我在CENTOS 6上。

我已经在1.6旁边安装了JRE 1.7并更改了/root/.bash_profile中的JAVA_HOME

[root@xxx log]# java -version
java version "1.7.0_60"
Java(TM) SE Runtime Environment (build 1.7.0_60-b19)
Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, mixed mode)

当我开始我的cassandra时，它崩溃了，错误：Cassandra 2.0 and later require Java 7 or later.

看起来cassandra仍在使用旧版本的java 1.6？我可以改变它的任何想法或任何建议如何解决这个问题？

感谢您的帮助！

更新

这是我的bash_profile：

export PATH
export JAVA_HOME=/opt/java/jre1.7.0_60
export PATH=/opt/java/jre1.7.0_60/bin:$PATH

我通过在init.d中执行脚本来运行Cassandra。

#!/bin/bash
# chkconfig: 2345 99 01
# description: Cassandra

. /etc/rc.d/init.d/functions

CASSANDRA_LOCK=/var/lock/subsys/cassandra

if [ ! -f $CASSANDRA_BIN ]; then
  echo "File not found: $CASSANDRA_BIN"
  exit 1
fi

start() {
  if [ -f $CASSANDRA_PID ] && checkpid `cat $CASSANDRA_PID`; then
    echo "Cassandra is already running."
    exit 0

  if [ $RETVAL -eq 0 ]; then
    touch $CASSANDRA_LOCK
    echo_success
  else
    echo_failure
  fi
  echo
  return $RETVAL
}

stop() {
  if [ ! -f $CASSANDRA_PID ]; then
    echo "Cassandra is already stopped."
    exit 0
  fi
  echo -n $"Stopping $PROGRAM: "
  $CASSANDRA_NODETOOL -h 127.0.0.1 decommission
  if kill `cat $CASSANDRA_PID`; then
    RETVAL=0
    rm -f $CASSANDRA_LOCK

  else

  echo
  [ $RETVAL = 0 ]
}

status_fn() {
  if [ -f $CASSANDRA_PID ] && checkpid `cat $CASSANDRA_PID`; then
    echo "Cassandra is running."
    exit 0
  else
    echo "Cassandra is stopped."
    exit 1

}
