centos搭建elasticsearch

原創 feifeichongtian 2018-08-28 10:23

1. 安裝配置JDK 8

（1）下載並解壓縮

[master@localhost ~]# tar -zxvf jdk-8u151-linux-x64.tar.gz -C /opt/java

（2）編輯環境變量 vi /etc/profile.d/custom.sh

[master@localhost~]# vi /etc/profile.d/custom.sh
[master@localhost ~]# cat /etc/profile.d/custom.sh
#!/bin/bash
#java path
export JAVA_HOME=/opt/java
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=.:$CLASSPATH:$JAVA_HOME/lib

（3）生效

[master@localhost ~]# source /etc/profile.d/custom.sh

（4）查看JDK版本

[master@localhost ~]# java -version
java version "1.8.0_151"
Java(TM) SE Runtime Environment (build 1.8.0_151-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.151-b12, mixed mode)
[master@localhost ~]#

2. ElasticSearch 下載安裝

（1）ElasticSearch 相關軟件下載官網 https://www.elastic.co/cn/downloads
圖潘在這裏
（2）wget 下載

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.1.0.tar.gz

（3）解壓
tar -zxvf elasticsearch-6.1.0.tar.gz
 （4）啓動報錯 原因：從5.0開始，ElasticSearch 安全級別提高了，不允許採用root帳號啓動，所以我們要添加一個用戶。在  root下面執行下面命令：
groupadd masteruseradd master -g master -p masterchown -R master:master /home/master/soft/elasticsearch-6.1.0tar -zxvf elasticsearch-6.1.0.tar.gz
 （5） 啓動：
[master@localhost elasticsearch-6.1.0]$ ./bin/elasticsearch
以下是啓動日誌：

[4]: system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk
解決方法：切換到root用戶，編輯limits.conf 添加類似如下內容
vi /etc/security/limits.conf 
添加如下內容:
* soft nofile 65536
* hard nofile 131072
* soft nproc 2048

報以下錯誤

解決方案是：
解決：切換到root用戶，進入limits.d目錄下修改配置文件。
vi /etc/security/limits.d/90-nproc.conf 
修改如下內容：
* soft nproc 1024

解決：切換到root用戶修改配置sysctl.conf

報以下錯誤：
ERROR: [1] bootstrap checks failed
[1]: system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk
解決方案：因爲Centos6不支持SecComp，而ES默認bootstrap.system_call_filter爲true進行檢測，所以導致檢測失敗，失敗後直接導致ES不能啓動。詳見 ：https://github.com/elastic/elasticsearch/issues/22899
在elasticsearch.yml中配置bootstrap.system_call_filter爲false，注意要在Memory下面:
 bootstrap.memory_lock: false
 bootstrap.system_call_filter: false
