article 2024/9/20 13:19:30

其他 UI 工具：cerebro

https://github.com/lmenezes/cerebro/releases

【1】环境准备

CentOS7
ElasticSearchv7.7.0
Nodejs

es-head需要nodejs环境编译，先看看机器中是否已经有nodejs环境，如果没有的话我们先要安装nodejs环境：

【1.1】node环境配置

nodjs官网：https://nodejs.org/en/download/

我下载的是：node-v14.16.1-linux-x64.tar.xz

wget https://nodejs.org/dist/v16.13.0/node-v16.13.0-linux-x64.tar.xz

#解压
tar -xJf node-v14.16.1-linux-x64.tar.xz

#换目录
mv node-v14.16.1-linux-x64 /opt/app/

#环境变量配置
echo "export NODE_HOME=/opt/app/node-v14.16.1-linux-x64">>/etc/profile
source /etc/profile
echo "export PATH=${PATH}:${NODE_HOME}/bin">>/etc/profile 
source /etc/profile

测试：

【1.2】es-head插件

（1）下载

地址：https://github.com/mobz/elasticsearch-head

可使用git命令在线下载，或者下载zip包之后，离线安装都可以。

使用git命令下载：

git clone https://github.com/mobz/elasticsearch-head.git

下载zip包并解压：

https://github.com/mobz/elasticsearch-head/archive/master.zip

unzip elasticsearch-head-master.zip
cd elasticsearch-head-master/ 
npm install

（2）如果报错　

则重新单独装一下这个：

　　npm install phantomjs-prebuilt@2.1.16 --ignore-scripts

　　如下图就成了　

（3）启动验证

前提：ES配置文件中有参数

http.cors.enabled: true
http.cors.allow-origin: "*"

修改完ES配置重启ES后，在es-head目录下使用下面的命令启动es-head:

npm run start

登录验证：IP+9100端口

【2】 ES配置密码

【2.1】修改配置文件：加载插件

http.cors.enabled: true
http.cors.allow-origin: "*"
http.cors.allow-headers: Authorization,X-Requested-With,Content-Length,Content-Type
xpack.security.enabled: true    #核心是这2个参数，如果设置了这一行参数，下面那行也必须加上
xpack.security.transport.ssl.enabled: true

重启ES生效

sudo -u elk nohup $ES_HOME/bin/elasticsearch >> $ES_HOME/output.log 2>&1 &

【2.2】配置ES：创建用户

cd $ES_HOME
bin/elasticsearch-setup-passwords interactive

交互界面：

[root@node01 elasticsearch-7.7.0]# bin/elasticsearch-setup-passwords interactive
future versions of Elasticsearch will require Java 11; your Java version from [/opt/app/jdk1.8.0_181/jre] does not meet this requirement
Initiating the setup of passwords for reserved users elastic,apm_system,kibana,logstash_system,beats_system,remote_monitoring_user.
You will be prompted to enter passwords as the process progresses.

Enter password for [elastic]: 
Reenter password for [elastic]:

Enter password for [logstash_system]: 
Reenter password for [logstash_system]: 
Enter password for [beats_system]: 
Reenter password for [beats_system]: 
Enter password for [remote_monitoring_user]: 
Reenter password for [remote_monitoring_user]: 
Changed password for user [apm_system]
Changed password for user [kibana]
Changed password for user [logstash_system]
Changed password for user [beats_system]
Changed password for user [remote_monitoring_user]
Changed password for user [elastic]

【2.3】验证

ES需要密码了；

【2.4】使用curl命令访问带有安全认证的ES

curl --user elastic:123456 -X GET http://uathd02:9200/noah/_doc/1?pretty

【3】整合

【3.1】kibana整合修改，用密码

修改Kibana配置

vim /opt/app/kibana-7.7.0-linux-x86_64/config/kibana.yml 

elasticsearch.username: "kibana"
elasticsearch.password: "123456"

重启kibana 生效

sudo -u elk  nohup $KB_HOME/bin/kibana > $KB_HOME/output.log 2>&1 &

验证：

可以用它做用户管理

【3.2】es-head使用密码访问ES

前面我们介绍过，推荐大家的ES开启安全认证，那么es-head怎么访问开启了XPACK安全认证的ES集群呢？把集群修改其中一项配置然后重启ES集群：

vim $ES_HOME/config/elasticsearch.yml

http.cors.enabled: true
http.cors.allow-origin: "*"
#http.cors.allow-headers: Authorization #这个配置改为下面的
http.cors.allow-headers: Authorization,X-Requested-With,Content-Length,Content-Type
xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true
