chown -R 1000:1000 /data/es/data-b/ chmod -R 777 /data/es/data-b/
最近想弄一個docker 環境，docker-composer 內容為 nginx,php,mysql,redis,elasticsearch.
但是在安裝es的時候出錯了，在網上找了幾天原因也沒找到，問題為：只要做持久化就會報錯，報錯內容如下
java.lang.IllegalStateException: failed to obtain node locks, tried [/usr/share/elasticsearch/data]; maybe these locations are not writable or multiple nodes were started on the same data path?
原來是 es鏡像的用戶是1000，所以在宿主機給改用戶賦權
chown -R 1000:1000 /data/es/data-b/
chmod -R 777 /data/es/data-b/
oK,這下不報這個錯了，但是又報內存不足的錯誤
max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
解決方案：
在/etc/sysctl.conf文件最后添加一行
vm.max_map_count=262144
執行/sbin/sysctl -p 立即生效
然后再啟動試試！！！！
注意，es8.0以上啟動的時候會默認開始用戶認證，用普通方式無法訪問！
一般都在啟動的時候會顯示密碼，但是docker的話就不知道怎么看密碼了 - -
所以我只能把es的配置文件映射出來，修改配置文件如下
1 cluster.name: "docker-cluster" 2 network.host: 0.0.0.0 3 4 #----------------------- BEGIN SECURITY AUTO CONFIGURATION ----------------------- 5 # 6 # The following settings, TLS certificates, and keys have been automatically 7 # generated to configure Elasticsearch security features on 15-03-2022 03:00:53 8 # 9 # -------------------------------------------------------------------------------- 10 11 # Enable security features 12 # 這里兩個設置成false 13 xpack.security.enabled: false 14 15 xpack.security.enrollment.enabled: false 16 17 18 # Enable encryption for HTTP API client connections, such as Kibana, Logstash, and Agents 19 xpack.security.http.ssl: 20 enabled: true 21 keystore.path: certs/http.p12 22 23 # Enable encryption and mutual authentication between cluster nodes 24 xpack.security.transport.ssl: 25 enabled: true 26 verification_mode: certificate 27 keystore.path: certs/transport.p12 28 truststore.path: certs/transport.p12 29 # Create a new cluster with the current node only 30 # Additional nodes can still join the cluster later 31 # 刪除或注釋這里的 cluster.initial_master_nodes: ["docker容器ID"] 32 33 #----------------------- END SECURITY AUTO CONFIGURATION -------------------------
到此可以訪問成功了！
