出錯是因為不能以root使用者的方式啟動，必須新建一個使用者和組

建立建立es組

[root@localhost elasticsearch-6.4.0]# groupadd eszu
複製程式碼

建立es使用者

[root@localhost elasticsearch-6.4.0]# useradd esyonghu
複製程式碼

指定使用者密碼

[root@localhost elasticsearch-6.4.0]# passwd esyonghu
更改使用者 esyonghu 的密碼 。

這時候elasticsearch已經成功啟動，我們來測試一下`curl localhost:9200`,如果得到了這些資料就說明成功了，但是在瀏覽器裡面並不能訪問，需要修改配置檔案

新開啟一個視窗,輸入curl localhost:9200

[root@localhost /]# curl localhost:9200
{
  "name" : "cRjfMu5",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "UhsXc7AVTaSCjSxLYNrRfw",

配置elasticsearch埠和ip

進入config資料夾，裡面有一個elasticsearch.yml檔案，使用vim elasticsearch.yml命令來編輯該檔案，新增如下內容

network.host: 192.168.145.129
http.port: 9200

再次啟動elasticsearch,會發現已經啟動不了了

修改錯誤，可以看到控制檯列印的資訊裡面有3個錯誤

[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
[2]: max number of threads [3802] for user [esyonghu] is too low, increase to at least [4096]
[3]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
複製程式碼

第一個錯誤需要將當前使用者的軟硬呼叫限制調大 [1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536] 切換到root使用者,然後執行vim /etc/security/limits.conf

[root@localhost elasticsearch-6.4.0]# vim /etc/security/limits.conf
複製程式碼

在檔案末尾加上

esyonghu soft nofile 65536
esyonghu hard nofile 131072
esyonghu soft nproc 2048
esyonghu hard nproc 4096
複製程式碼

第二個錯誤需要修改/etc/security/limits.d/20-nproc.conf 檔案 [2]: max number of threads [3802] for user [esyonghu] is too low, increase to at least [4096]

修改/etc/security/limits.d/20-nproc.conf 檔案，這裡需要注意一下，可能不叫20-nproc.conf 也可能是90-nproc.conf

vim /etc/security/limits.d/20-nproc.conf
複製程式碼

在檔案中新增

esyonghu   soft    nproc     4096
複製程式碼

第三個錯誤需要修改/etc/sysctl.conf [3]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144] 使用命令 vim /etc/sysctl.conf來編輯該檔案，在檔案中加入如下內容

加上vm.max_map_count=262144
複製程式碼

需要使改檔案生效，執行sysctl -p

[root@localhost etc]# sysctl -p
vm.max_map_count = 262144
複製程式碼

再次切換到esyonghu去elasticsearch檔案目錄啟動elasticsearch

[root@localhost elasticsearch-6.4.0]# su esyonghu
[esyonghu@localhost elasticsearch-6.4.0]$ 
[esyonghu@localhost elasticsearch-6.4.0]$ cd /home/elasticsearch/elasticsearch-6.4.0
[esyonghu@localhost elasticsearch-6.4.0]$ ./bin/elasticsearch
現在啟動成功了，使用瀏覽器訪問試一下
複製程式碼

關閉防火牆

再次訪問的時候發現還是不行，這時候需要關閉防火牆
檢查防火牆狀態
先切換到root使用者
[esyonghu@localhost elasticsearch-6.4.0]$ su root
密碼：
[root@localhost elasticsearch-6.4.0]# 

檢視防火牆狀態
[root@localhost elasticsearch-6.4.0]# firewall-cmd --state
running
[root@localhost elasticsearch-6.4.0]# 

狀態是running,需要關閉防火牆
執行systemctl stop firewalld.service
[root@localhost elasticsearch-6.4.0]# systemctl stop firewalld.service

再次檢查防火牆狀態，就是為執行了
[root@localhost elasticsearch-6.4.0]# firewall-cmd --state
not running
[root@localhost elasticsearch-6.4.0]# 
複製程式碼

切換到esyonghu再次啟動

[root@localhost elasticsearch-6.4.0]# su esyonghu
[esyonghu@localhost elasticsearch-6.4.0]$ 
[esyonghu@localhost elasticsearch-6.4.0]$ ./bin/elasticsearch
[2018-08-30T12:09:59,267][INFO ][o.e.n.Node               ] [] initializing ...
啟動成功，使用瀏覽器訪問就可以了
複製程式碼

以後臺方式啟動elasticsearch

./bin/elasticsearch -d

[esyonghu@localhost elasticsearch-6.4.0]$ ./bin/elasticsearch -d
[esyonghu@localhost elasticsearch-6.4.0]$ 
 
複製程式碼

結束elastsearch

輸入jps命令
殺死elasticsearch程式
複製程式碼

如果繫結本地ip失敗，那麼在elasticsearch.yml裡面加上

bootstrap.memory_lock: false
bootstrap.system_call_filter: false
複製程式碼
