logstash6 和 es6 兼容jdk1.7

ES的启动文件 修改为如下

#!/bin/bash

# CONTROLLING STARTUP:
#
# This script relies on a few environment variables to determine startup
# behavior, those variables are:
#
#   ES_PATH_CONF -- Path to config directory
#   ES_JAVA_OPTS -- External Java Opts on top of the defaults set
#
# Optionally, exact memory values can be set using the `ES_JAVA_OPTS`. Note that
# the Xms and Xmx lines in the JVM options file must be commented out. Example
# values are "512m", and "10g".
#
#   ES_JAVA_OPTS="-Xms8g -Xmx8g" ./bin/elasticsearch
# 我添加的 start
export JAVA_HOME=/srv/java/jdk1.8.0_151/
export PATH=$JAVA_HOME/bin:$PATH
# 我添加的 end
source "`dirname "$0"`"/elasticsearch-env

logstash的配置文件修改为如下

#!/bin/sh
# Run logstash from source
#
# This is most useful when done from a git checkout.
#
# Usage:
#   bin/logstash <command> [arguments]
#
# See 'bin/logstash --help' for a list of commands.
#
# Supported environment variables:
#   LS_JAVA_OPTS="xxx" to append extra options to the JVM options provided by logstash
#
# Development environment variables:
#   DEBUG=1 to output debugging information

export JAVA_HOME=/srv/java/jdk1.8.0_151/
export PATH=$JAVA_HOME/bin:$PATH

# was launched from a symlink, rather than a full path to the Logstash binary
