chown -R 1000:1000 /data/es/data-b/ chmod -R 777 /data/es/data-b/
最近想弄一个docker 环境，docker-composer 内容为 nginx,php,mysql,redis,elasticsearch.
但是在安装es的时候出错了，在网上找了几天原因也没找到，问题为：只要做持久化就会报错，报错内容如下
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?
原来是 es镜像的用户是1000，所以在宿主机给改用户赋权
chown -R 1000:1000 /data/es/data-b/
chmod -R 777 /data/es/data-b/
oK,这下不报这个错了，但是又报内存不足的错误
max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
解决方案：
在/etc/sysctl.conf文件最后添加一行
vm.max_map_count=262144
执行/sbin/sysctl -p 立即生效
然后再启动试试！！！！
注意，es8.0以上启动的时候会默认开始用户认证，用普通方式无法访问！
一般都在启动的时候会显示密码，但是docker的话就不知道怎么看密码了 - -
所以我只能把es的配置文件映射出来，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 # 这里两个设置成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 # 删除或注释这里的 cluster.initial_master_nodes: ["docker容器ID"] 32 33 #----------------------- END SECURITY AUTO CONFIGURATION -------------------------
到此可以访问成功了！
