Elasticsearch

搜索引擎解決方案 版本 elasticsearch 5.6

Author : Janloong Do_O

配置

elasticsearch.in.sh
export JAVA_HOME=/usr/local/jdk8
export JRE_HOME=/usr/local/jdk8/jre

root用戶運行

ES_JAVA_OPTS="-Des.insecure.allow.root=true"


錯誤1
如果這時報錯"max virtual memory areas vm.maxmapcount [65530] is too low"，運行
當前生效
$ sudo sysctl -w vm.max_map_count=262144
修改文件/etc/sysctl.conf
vm.max_map_count= 262144
執行命令
sysctl -p

錯誤2
max file descriptors [65535] forelasticsearch process likely too low, increase to at least [65536]
/etc/security/limits.conf，末尾增加如下內容
soft nofile 65536
hard nofile 65536
max virtual memory
或
* - nofile65536
* - memlock unlimited
需要重啓


接觸ip綁定限制 config/elasticsearch.yml
network.host: 0.0.0.0

基礎命令

查看當前節點的所有index
$ curl -X GET 'http://localhost:9200/_cat/indices?v'

新增index
$ curl -X PUT 'localhost:9200/weather'

刪除一個index
$ curl -X DELETE 'localhost:9200/weather'


安裝xpack後修改密碼
curl -XPUT -u elastic 'localhost:9200/_xpack/security/user/elastic/_password' -d '{
  "password" : "elastic"
}'
