docker安裝elasticsearch報錯

按照elasticsearch的官方文檔用docker安裝7.7.1版本的es,報錯

(順帶說以下，如果我把鏡像的版本換成最新的7.12.1，不會報錯。用7.7.1的就會報錯）

[root@webapi4-app-22-151 workspace]# docker run -p 9200:9200 -p 9300:9300 -e “discovery.type=single-node” docker.elastic.co/elasticsearch/elasticsearch:7.7.1

大概搜了下這個問題,別人的報錯都是/usr/share/elasticsearch目錄,而我的是/tmp目錄,不太一樣.

我用別人的解決方法

• 設(shè)置環(huán)境變量TAKE_FILE_OWNERSHIP=true
• 容器內(nèi)chown -R 1000:0 /usr/share/elasticsearch/{data,logs}
• 把宿主機的掛載目錄權(quán)限設(shè)置成777

這三種辦法不管用,還是報錯,所以,使出絕招,進入容器里面排錯.

啟動一個臨時容器,默認(rèn)執(zhí)行命令/bin/bash

默認(rèn)執(zhí)行命令變成了/bin/bash,而不是docker-entrypoint.sh,容器主進程是/bin/bash所以容器不會遇到錯誤導(dǎo)致退出

[root@webapi4-app-22-151 workspace]# docker run -itd -e “discovery.type=single-node” docker.elastic.co/elasticsearch/elasticsearch:7.7.1 /bin/bash
5f733625a5808d15c8895cb12ddf94845f5f1b57960edd1d224544cf8da08bab
[root@webapi4-app-22-151 workspace]# docker exec -it 5f7 bash
[root@5f733625a580 elasticsearch]#
#執(zhí)行es容器的啟動腳本,報錯
[root@5f733625a580 elasticsearch]# sh /usr/local/bin/docker-entrypoint.sh

就是出現(xiàn)的這個錯誤，/tmp目錄

然后在容器里給/tmp目錄授權(quán)777，重新執(zhí)行腳本

[root@5f733625a580 elasticsearch]# chmod 777 /tmp
[root@5f733625a580 elasticsearch]# sh /usr/local/bin/docker-entrypoint.sh

報了新的錯誤

Error opening log file ‘logs/gc.log’: Permission denied

給容器內(nèi)的/usr/share/elasticsearch目錄設(shè)置權(quán)限

[root@5f733625a580 elasticsearch]# chown -R 1000:0 /usr/share/elasticsearch/
[root@5f733625a580 elasticsearch]# sh /usr/local/bin/docker-entrypoint.sh

最后elasticsearch服務(wù)啟動成功

總結(jié): 先配置

chmod 777 /tmp
chown -R 1000:0 /usr/share/elasticsearch/

這兩條命令再執(zhí)行腳本docker-entrypoint.sh

解決問題后

使用docker-compose安裝，docker-compose.yml:

version: '2'
services:
  es:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.7.1
    container_name: es
    ports:
    - 9200:9200
    environment:
    - discovery.type=single-node
    - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
    - /data/elk/es/data:/usr/share/elasticsearch/data
    command:
    - /bin/bash 
    - -c 
    - |  
        chmod 777 /tmp
        chown -R 1000:0 /usr/share/elasticsearch/
        sh /usr/local/bin/docker-entrypoint.sh

啟動成功

[root@webapi4-app-22-151 workspace]# docker-compose up -d

目前暫時解決了這個問題，但是應(yīng)該有更優(yōu)的解決方法

總結(jié)

以上為個人經(jīng)驗，希望能給大家一個參考，也希望大家多多支持腳本之家。
