ELK 之 elasticsearch-7.7.0 及kibana-7.7.0 安装 并指定JDK

却显示“ 拒绝了我们的连接请求 ”，因此我们还需要配置一下 Elasticsearch

以允许我们进行外网访问，进入 elasticsearch-7.7.0 下的 config 目录，编辑

elasticsearch.yml 文件，删除 network.host 前的 # 字符，并写入服务器的地址并

保存

nohup ./kibana &

提示：

[~]$ appending output to nohup.out

嗯，证明运行成功，同时把程序运行的输出信息放到当前目录的 nohup.out 文件中去。

nohup 命令

用途：LINUX命令用法，不挂断地运行命令。

 

查看kibana是否启动了，用如下命令：

netstat -tunlp|grep 5601

netstat -tunlp

由于我们日常的代码开发都是使用的JDK1.8，所以这里不会把JAVA_HOME配置成JDK11，我们只需更改Elasticsearch的启动文件，使它指向我们下载的JDK11.

修改配置文件
[root@centos7 bin]# pwd
/home/wx/elasticsearch-7.9.0/bin
[root@centos7 bin]# vi elasticsearch
添加以下几行内容
#配置自己的jdk11
export JAVA_HOME=/usr/local/jdk-11.0.8/
export PATH=$JAVA_HOME/bin:$PATH

#添加jdk判断
if [ -x "$JAVA_HOME/bin/java" ]; then
        JAVA="/usr/local/jdk-11.0.8//bin/java"
else
        JAVA=`which java`
fi

# behavior, those variables are:

# Optionally, exact memory values can be set using the `ES_JAVA_OPTS`. Example
