ElasticSearch 安裝報錯整理
ElasticSearch 安裝報錯整理
單機安裝報錯
初次啟動服務
/opt/elasticsearch-5.5.2/bin/elasticsearch
當使用root賬戶呼叫啟動命令出現錯誤資訊,錯誤提示資訊如下:
[2017-08-30T13:32:17,003][WARN ][o.e.b.ElasticsearchUncaughtExceptionHandler] [ELK-node1] 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:127) ~[elasticsearch-5.5.2.jar:5.5.2] at org.elasticsearch.bootstrap.Elasticsearch.execute(Elasticsearch.java:114) ~[elasticsearch-5.5.2.jar:5.5.2] at org.elasticsearch.cli.EnvironmentAwareCommand.execute(EnvironmentAwareCommand.java:67) ~[elasticsearch-5.5.2.jar:5.5.2] at org.elasticsearch.cli.Command.mainWithoutErrorHandling(Command.java:122) ~[elasticsearch-5.5.2.jar:5.5.2] at org.elasticsearch.cli.Command.main(Command.java:88) ~[elasticsearch-5.5.2.jar:5.5.2] at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:91) ~[elasticsearch-5.5.2.jar:5.5.2] at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:84) ~[elasticsearch-5.5.2.jar:5.5.2] Caused by: java.lang.RuntimeException: can not run elasticsearch as root at org.elasticsearch.bootstrap.Bootstrap.initializeNatives(Bootstrap.java:106) ~[elasticsearch-5.5.2.jar:5.5.2] at org.elasticsearch.bootstrap.Bootstrap.setup(Bootstrap.java:194) ~[elasticsearch-5.5.2.jar:5.5.2] at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:351) ~[elasticsearch-5.5.2.jar:5.5.2] at org.elasticsearch.bootstrap.Elasticsearch.init(Elasticsearch.java:123) ~[elasticsearch-5.5.2.jar:5.5.2] ... 6 more
建立新使用者
由於Elasticsearch可以接收使用者輸入的指令碼並且執行,為了系統安全考慮,不允許root賬號啟動,所以建議給Elasticsearch
單獨建立一個使用者來執行Elasticsearch
。
命令格式 useradd ymq(使用者名稱) -g ymq(所屬組名) -p ymq(密碼)
groupadd ymq
useradd ymq -g ymq -p ymq
授權訪問組許可權
命令格式: chown -R ymq
(所屬使用者) :
ymq
(所屬使用者組名) /opt/elasticsearch-5.5.2
(要更改的檔案路徑)
chown -R ymq:ymq /opt/elasticsearch-5.5.2 chmod -R 777 /opt/elasticsearch-5.5.2
授權 root 許可權
命令格式: ymq 使用者 root 許可權 ` NOPASSWD `意思是 不用輸密碼
chmod 777 /etc/sudoers
vi /etc/sudoers
root ALL=(ALL) ALL
#新增ymq 使用者 root 許可權
ymq ALL=(ALL) NOPASSWD:ALL
pkexec chmod 0440 /etc/sudoers
su ymq
/opt/elasticsearch-5.5.2/bin/elasticsearch
如果報如下錯誤

以下錯誤都切換到 root
使用者進項修改
su root
錯誤
[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536
編輯 limits.conf
在第一行加上如下內容
cat /etc/security/limits.conf
* soft nofile 65536
* hard nofile 131072
* soft nproc 2048
* hard nproc 4096
錯誤
[2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
編輯 limits.conf
在第一行加上如下內容
cat /etc/sysctl.conf
vm.max_map_count = 655360
執行 sysctl -p
sysctl -p
刪除data目錄下的資料(如果是新解壓的安裝包就不必了)
異常 IllegalStateException

刪除 安裝目錄下/data
cd /opt/elasticsearch-5.5.2/data
rm -rf nodes
異常 RemoteTransportException

rm -rf nodes
異常 ElasticsearchUncaughtExceptionHandler

再次啟動服務
切到 ymq
使用者嘗試啟動服務 加 -d
後臺啟動
su ymq
/opt/elasticsearch-5.5.2/bin/elasticsearch -d
jvm 記憶體記憶體修改
vi /opt/elasticsearch-5.5.2/config/jvm.options
-Xms2g --》修改為512m
-Xmx2g --》修改為512m
檢視日誌
ymq
及時叢集名稱
less /opt/elasticsearch-5.5.2/logs/ymq.log
檢視埠
netstat -nltp

systemctl stop firewalld.service
Elasticsearch 複製叢集配置
不推薦按照以下步驟,可以按照上面介紹的單機配置依次安裝
在node1
ROOT 使用者下操作
su root
把本機配置的檔案複製到 node2,node3叢集
for a in {2..3} ; do scp -r /opt/elasticsearch-5.5.2/ node$a:/opt/elasticsearch-5.5.2/ ; done
ssh 登入
node2,node3叢集,建立新使用者,授權訪問組許可權,並且授權訪問/etc/sudoers
給root許可權
for a in {2..3} ; do ssh node$a "source /etc/profile; groupadd ymq; useradd ymq -g ymq -p ymq; chown -R ymq:ymq /opt/elasticsearch-5.5.2; chmod 777 /etc/sudoers;" ; done
for a in {2..3} ; do scp -r /etc/sudoers node$a:/etc/sudoers ; done
複製 limits.conf
到 node2,node3叢集
for a in {2..3} ; do scp -r /etc/security/limits.conf node$a:/etc/security/limits.conf ; done
複製 sysctl.conf
到 node2,node3叢集
for a in {2..3} ; do scp -r /etc/sysctl.conf node$a:/etc/sysctl.conf ; done
複製 jvm.options
到 node2,node3叢集
for a in {2..3} ; do scp -r /opt/elasticsearch-5.5.2/config/jvm.options node$a:/opt/elasticsearch-5.5.2/config/jvm.options ; done
執行 sysctl -p
操作
for a in {2..3} ; do ssh node$a "source /etc/profile; sysctl -p ; " ; done
vi /opt/elasticsearch-5.5.2/config/elasticsearch.yml
node.name: 換個名字,可以ELK-node2
,ELK-node3
node.name: ELK-node1
後臺啟動
後臺啟動node1,node2,node3 服務
su ymq
/opt/elasticsearch-5.5.2/bin/elasticsearch -d
檢視node1,node2,node3埠使用情況
netstat -nltp
