安装 elasticsearch-head
elasticsearch 7.x 已经无法直接调用 plugin 进行 elasticsearch-head 安装， 参考下面安装步骤
1 下载 git
# git clone https://github.com/mobz/elasticsearch-head
2 添加 yum 源
/etc/yum.repso.d/yarn.repo
[yarn]
name=Yarn Repository
baseurl=https://dl.yarnpkg.com/rpm/
enabled=1
gpgcheck=0
gpgkey=https://dl.yarnpkg.com/rpm/pubkey.gpg
3 下载 nodejs
# curl --silent --location https://rpm.nodesource.com/setup_10.x | bash -
## Installing the NodeSource Node.js 10.x repo...
## Inspecting system...
+ rpm -q --whatprovides redhat-release || rpm -q --whatprovides centos-release || rpm -q --whatprovides cloudlinux-release || rpm -q --whatprovides sl-release
+ uname -m
## Confirming "el7-x86_64" is supported...
+ curl -sLf -o /dev/null 'https://rpm.nodesource.com/pub_10.x/el/7/x86_64/nodesource-release-el7-1.noarch.rpm'
## Downloading release setup RPM...
+ mktemp
+ curl -sL -o '/tmp/tmp.sy79c77aLt' 'https://rpm.nodesource.com/pub_10.x/el/7/x86_64/nodesource-release-el7-1.noarch.rpm'
## Installing release setup RPM...
+ rpm -i --nosignature --force '/tmp/tmp.sy79c77aLt'
## Cleaning up...
+ rm -f '/tmp/tmp.sy79c77aLt'
## Checking for existing installations...
+ rpm -qa 'node|npm' | grep -v nodesource
## Run `sudo yum install -y nodejs` to install Node.js 10.x and npm.
## You may also need development tools to build native addons:
sudo yum install gcc-c++ make
## To install the Yarn package manager, run:
curl -sL https://dl.yarnpkg.com/rpm/yarn.repo | sudo tee /etc/yum.repos.d/yarn.repo
sudo yum install yarn
4 按照提示安装 yarn
先安装 gcc-c++ 与 make
[root@ns-yun-020064 git]# yum install gcc-c++ make
