1.安裝jdk1.8

2.問題1：org.elasticsearch.bootstrap.StartupException: java.lang.RuntimeException: can not run elasticsearch as root

解決方案：

因為安全問題elasticsearch 不讓用root用戶直接運行，所以要創建新用戶
建議創建一個單獨的用戶用來運行ElasticSearch
創建elsearch用戶組及elsearch用戶
groupadd elsearch
useradd elsearch -g elsearch -p elasticsearch

chown -R elsearch:elsearch ./elasticsearch-5.4.1?? ?用戶目錄權限

3.問題2：

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

vim config/elasticsearch.yml 添加如下：
bootstrap.system_call_filter: false

4.問題3：

ERROR: bootstrap checks failed max file descriptors [10240] for elasticsearch process likely too low, increase to at least [65536] max number of threads [1024] for user [elsearch] likely too low, increase to at least [2048] max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144] [2016-11-14T10:22:17,569][INFO ][o.e.n.Node ] [mysteel-node1] stopping ...

切換到root用戶

vi /etc/security/limits.conf

添加如下內容:

* soft nofile 65536
* hard nofile 131072
* soft nproc 2048
* hard nproc 4096

vi /etc/security/limits.d/90-nproc.conf
修改如下內容：
* soft nproc 1024
#修改為
* soft nproc 2048

vi /etc/sysctl.conf?
添加下面配置：
vm.max_map_count=655360
并執行命令：
sysctl -p
重新登錄elsearch
然后，重新啟動elasticsearch，即可啟動成功。

安裝kibana：

解壓之后修改配置文件：./config/kibana.yml

server.host: "192.168.152.39" elasticsearch.url: "http://192.168.152.39:9200"

?
