配置环境变量

export PATH=$JAVA_HOME/bin:/data/install/git/bin:$NODE_HOME/bin:$PATH

新增配置

在这里插入图片描述

刷新配置

[root@localhost elkb]# node -v
v14.16.0
[root@localhost elkb]# npm -version
6.14.11
[root@localhost elkb]#

安装淘宝cnpm

[root@localhost elkb]# cd elasticsearch-head/
[root@localhost elasticsearch-head]# npm install -g cnpm --registry=https://registry.npm.taobao.org
npm WARN deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142
npm WARN deprecated har-validator@5.1.5: this library is no longer supported
/usr/local/elkb/node-v14.16.0-linux-x64/bin/cnpm -> /usr/local/elkb/node-v14.16.0-linux-x64/lib/node_modules/cnpm/bin/cnpm
+ cnpm@6.1.1
added 694 packages from 973 contributors in 36.687s
[root@localhost elasticsearch-head]# cnpm install

########发现报错
Phantom installation failed Error: Command failed: tar jxf /tmp/phantomjs/phantomjs-2.1.1-linux-x86_64.tar.bz2

发现报错，原因是没有bzip2工具，安装即可，然后重新执行cnpm install成功

[root@localhost elasticsearch-head]# yum install bzip2
[root@localhost elasticsearch-head]# cnpm install
