eleasticsearch head 插件 安裝 如何在 CentOS7 中安裝 Nodejs

安裝版本：10.13.0

1、安裝必要的編譯軟件包

sudo yum install gcc gcc-c++

2、從源碼下載Nodejs

cd /usr/local/src
wget https://npm.taobao.org/mirrors/node/v10.13.0/node-v10.13.0.tar.gz

 

 

3、解壓 nodejs 安裝包

tar xvf node-v10.13.0.tar.gz

 

4、進入解壓的 node 文件夾，開始編譯

cd node-v10.13.0/
./configure
make

注：make過程較爲耗時，可能須要30分鐘以上

 

 

 若是編譯過程當中報 C++ Compiler too old, need g++ 4.9.4 or clang++ 3.4.2 (CXX=g++)，那須要先升級一下 gcc，編譯正常的話請忽略直接跳至第五步開始安裝

檢查 gcc 的版本

gcc -v

若是版本號低於4.9.4，請先升級gcc，升級的方法請參考個人另外一篇文章《如何在Centos7中安裝gcc》

5、安裝Nodejs

sudo make install

6、驗證是否正確安裝

node -v

新建用戶 elk 用於 啓動 elasticsearch

[root@swarm02 skyworking]# useradd elk
[root@swarm02 skyworking]# passwd elk

[root@swarm02 data]# chown -R elk:elk skyworking/

新建elk 用於搭建 elk 環境

[root@swarm02 data]# mkdir elk
[root@swarm02 data]# ls
elk  skyworking
[root@swarm02 data]# chown -R elk:elk elk/
[root@swarm02 data]# ls -l

drwxr-xr-x 2 elk elk 39 Apr 30 03:37 skyworking



[elk@swarm02 skyworking]$ cd /data/elk/
[elk@swarm02 elk]$ ls
[elk@swarm02 elk]$ mkdir elasticsearch
[elk@swarm02 elk]$ cd elasticsearch/
[elk@swarm02 elasticsearch]$ pwd
/data/elk/elasticsearch


將文件解壓到 master目錄
[elk@swarm02 elasticsearch]$ ls -l

[elk@swarm02 elasticsearch]$ tar -zxvf elasticsearch-6.5.4.tar.gz


重命名目錄
[elk@swarm02 elasticsearch]$ ls
elasticsearch-6.5.4  elasticsearch-6.5.4.tar.gz
[elk@swarm02 elasticsearch]$ mv elasticsearch-6.5.4 master
[elk@swarm02 elasticsearch]$ ls

中止ES服務
ps -ef| grep elasticsearch | grep -v grep | awk '{print $2}'
kill -9 pid [上一步所輸出的pid]

啓動服務 ，主要要用非 root 用戶，本系統是 su elk 
/data/elk/elasticsearch/master/bin/elasticsearch -d
/data/elk/elasticsearch/slave01/bin/elasticsearch  -d
/data/elk/elasticsearch/slave02/bin/elasticsearch  -d
