解决：

#下载
wget https://npm.taobao.org/mirrors/phantomjs/phantomjs-2.1.1-linux-x86_64.tar.bz2
tar -jxvf phantomjs-2.1.1-linux-x86_64.tar.bz2
#加入环境变量
vim /etc/profile
#末尾加入，注意文件路径
export PATH=$PATH:/usr/local/phantomjs-2.1.1-linux-x86_64/bin
#执行
source /etc/profile

回到项目目录后， rm -rf ./node_modules 后再次执行 npm install --unsafe-perm。
完美解决！！！

修改端口

[root@ecs-gDQ es-head]# vi Gruntfile.js 

 connect: {
                        server: {
                                options: {
                                        port: 8401,
                                        base: '.',
                                        keepalive: true
                                }
                        }
                }

vi _site/app.js

 init: function(parent) {
                        this._super();
                        this.prefs = services.Preferences.instance();
                        this.base_uri = this.config.base_uri || this.prefs.get("app-base_uri") || "http://ab.5xn.online:8301";

which nohup
.bash_profile中并source加载
 
如果没有就安装吧
yum provides */nohup
 
nohup npm start &

修改vi elasticsearch.yml

追加：

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

重启：

[elsearch@ecs-gDQ elasticsearch-7.5.1]$ ./bin/elasticsearch -d
