elasticsearch 6.4.2 linux 安裝以及問題
1、安裝elasticsearch
官網下載
下載得到壓縮包 解壓
#tar -zxvf elasticsearch-6.4.2.tar.gz
#mv elasticsearch-6.4.2 /usr/local/elasticsearch
#cd /usr/local/elasticsearch/
啟動elasticsearch
配置
#vi config/elasticsearch.yml network.host: 0.0.0.0
http.port: 9200root 使用者啟動會報錯 安全機制
所以新建一個使用者 賦予elasticsearch許可權
#chown -R elsk elasticsearch
切換到elsk使用者 啟動
./bin/elasticsearch報錯：
ERROR: bootstrap checks failed
#vi config/elasticsearch.yml
bootstrap.memory_lock: false
bootstrap.system_call_filter: false報錯：
max number of threads [2048] for user [elsk] is too low, increase to at least [4096]
需修改
#vi /etc/security/limits.conf * soft nofile 65536 * hard nofile 131072 * soft nproc 2048 * hard nproc 4096
#vi /etc/security/limits.d/90-nproc.conf
* soft nproc 4096
#sysctl -p後臺啟動 -d
#./bin/elasticsearch -d返回以下內容標識成功
curl "http://ip:9200/"
