安裝ElasticSearch-6.2.3所遇到的安裝報錯

（1）記憶體不足。

Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000c5330000, 986513408, 0) failed; error='Cannot allocate memory' (errno=12)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 986513408 bytes for committing reserved memory.
# An error report file with more information is saved as:複製程式碼

解決辦法：減少啟動程式所需記憶體，或加大記憶體，如關閉一些程式。

方法一：擴大虛擬機器記憶體，直接更改虛擬機器記憶體就好了，此方法省略。

方法二：減小所需記憶體的辦法。

進入config，命令： cd config

修改jvm.properties檔案,命令： vi jvm.options

可以看到此版本它的預設記憶體是1G，我們把它設小一點。

儲存退出。

（2）不能使用管理員許可權啟動

[WARN ][o.e.b.ElasticsearchUncaughtExceptionHandler] [] uncaught exception in thread [main]
org.elasticsearch.bootstrap.StartupException: java.lang.RuntimeException: can not run elasticsearch as root
	at org.elasticsearch.bootstrap.Elasticsearch.init(Elasticsearch.java:125) ~[elasticsearch-6.2.3.jar:6.2.3]
複製程式碼

解決辦法：

新增使用者，用新使用者許可權去開啟elasticsearch。

命令格式： useradd 使用者名稱 -g 所屬組名 -p 密碼

groupadd ymq
useradd  ymq -g ymq -p ymq
複製程式碼
授權訪問組許可權

命令格式： chown -R 所屬使用者 ： 所屬使用者組名 更改許可權的檔案路徑

chown -R ymq:ymq 路徑
chmod -R 777 路徑複製程式碼

（3）127.0.0.1:9200能訪問，ip+埠無法訪問

修改es配置檔案elasticsearch.yml

加上:network.host: 0.0.0.0

（4）

ERROR: [3] bootstrap checks failed
[1]: max file descriptors [65535] for elasticsearch process is too low, increase to at least [65536]
[2]: max number of threads [3889] for user [myes] is too low, increase to at least [4096]

複製程式碼

用root許可權修改limits.conf（/etc/seacurity）在第一行增加以下內容：

* soft nofile 65536
* hard nofile 131072
* soft nproc 2048
* hard nproc 4096複製程式碼
[3]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]複製程式碼

修改配置檔案/etc/sysctl.conf在第一行加上下面這句：

vm.max_map_count = 655360

執行命令： sysctl -p

將es安裝目錄及其子目錄賦予許可權：

sudo chown -R 使用者 elasticsearch-6.0.0

sudo chgrp -R 使用者組 elasticsearch-6.0.0
