Elastic Search 安装部署注意事项

ES 启动：bin/elasticsearch -d
ES 关闭：
ps -ef | grep elastic

让全网访问 elasticsearch
修改 elasticsearch.yml
将 network.host 设置为 0.0.0.0

问题二：ERROR: bootstrap checks failed
max file descriptors [4096] for elasticsearch process likely too low, increase to at least [65536]
max number of threads [1024] for user [lishang] likely too low, increase to at least [2048]
解决：切换到 root 用户，编辑 limits.conf 添加类似如下内容
vi /etc/security/limits.conf
添加如下内容:

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

问题三：max number of threads [1024] for user [lish] likely too low, increase to at least [2048]
解决：切换到 root 用户，进入 limits.d 目录下修改配置文件。
vi /etc/security/limits.d/90-nproc.conf
修改如下内容：

• soft nproc 1024
  #修改为
• soft nproc 2048

问题四：max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144]
解决：切换到 root 用户修改配置 sysctl.conf
vi /etc/sysctl.conf
添加下面配置：
vm.max_map_count=655360
并执行命令：
sysctl -p

注意：jvm.options
-Xms512m
-Xmx512m
需要一致

ES 更新 Mapping，

1. curl -XPUT localhost:9200/my_index/my_type/_mapping -d '
2. {

3.  "my_type": {  
   

4.      "properties": {  
   

5.          "created": {  
   

6.              "type":   "multi_field",  
   

7.              "fields": {  
   

8.                  "created": { "type": "string" },  
   

9.                  "date":    { "type": "date"   }  
   

10.             }  
    

11.         }  
    

12.     }  
    

13. }  
    

14. }
