.net core 与ELK（2）安装Elasticsearch可视化工具

elasticsearch-head是els的界面插件，地址https://github.com/mobz/elasticsearch-head

1.进入github并下载

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

2.解压

[root@localhost /usr/local/src]# unzip master.zip
[root@localhost /usr/local/src]# mv elasticsearch-head-master/ /usr/local/
[root@localhost /usr/local/src]# ls /usr/local/elasticsearch-head-master/
dockerfile         elasticsearch-head.sublime-project  grunt_filesets.js  licence       plugin-descriptor.properties  readme.textile  src
dockerfile-alpine  gruntfile.js                        index.html         package.json  proxy                         _site           test
[root@localhost /usr/local/src]#

3.下载node

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

[root@localhost /usr/local/src]# wget https://nodejs.org/dist/v8.11.3/node-v8.11.3-linux-x64.tar.xz
[root@localhost /usr/local/src]# tar -jxvf node-v8.11.3-linux-x64.tar.xz -c /usr/local/
[root@localhost /usr/local/src]# mv /usr/local/node-v8.11.3-linux-x64/ /usr/local/node-8.11.3

4.配置node环境变量

[root@localhost /usr/local/src]# vim /etc/profile
export node_home=/usr/local/node-8.11.3
export path=$path:$node_home/bin
[root@localhost /usr/local/src]# source /etc/profile
[root@localhost /usr/local/src]# node -v  # 输出版本号则代表配置成功
v8.11.3
[root@localhost /usr/local/src]#

5.npm install

[root@localhost /usr/local/src]# cd /usr/local/elasticsearch-head-master/
[root@localhost /usr/local/elasticsearch-head-master]# npm install phantomjs-prebuilt@2.1.14 --ignore-scripts  # 因为有墙，phantomjs-prebuilt需要单独安装，不然会失败
[root@localhost /usr/local/elasticsearch-head-master]# npm install

6.需改配置

[root@localhost /usr/local/elasticsearch-head-master]# vim gruntfile.js
connect: {
        server: {
                options: {
                        hostname: '0.0.0.0',  # 增加这段
                        port: 9100,
                        base: '.',
                        keepalive: true
                }
        }
}
[root@localhost /usr/local/elasticsearch-head-master]#

7.开启els跨域

[root@localhost /usr/local/elasticsearch-head-master]# cd ../elasticsearch-5.5.2/config/
[root@localhost /usr/local/elasticsearch-5.5.2/config]# vim elasticsearch.yml  # 文件末尾加上如下配置
http.cors.enabled: true
http.cors.allow-origin: "*"
[root@localhost /usr/local/elasticsearch-5.5.2/config]# 

8.重启els

[elsearch@localhost bin]$ ps -ef | grep ela
[elsearch@localhost bin]$ kill -9 10899
[elsearch@localhost bin]$ ./elasticsearch -d

9.启动elasticsearch-head

[elsearch@localhost elasticsearch-head-master]$ npm run start
