#报错了：docker: error pulling image configuration: download failed after attempts=6: dial tcp 104.18.124.25:443: i/o timeout.

解决方案：配置阿里云/腾讯云镜像地址： “registry-mirrors”: [“https://yxzrazem.mirror.aliyuncs.com”]

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{"registry-mirrors": ["https://mirror.ccs.tencentyun.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

再次启动es docker:报错"Caused by: java.nio.file.AccessDeniedException: /usr/share/elasticsearch/data/nodes",
解决：权限不够：
chmod 777 /opt/dockerV/es/**

再次启动：ok

配置插件:ik_smart:

配置扩展字典：

创建my.dic文件：
酸衡子
樊孤殷衡
见路不走

重启容器：

因为一些特殊原因：没能打开防火墙端口：先通过nginx转发去操作：

下载logstash:[root@VM-24-17-centos opt]# wget https://artifacts.elastic.co/downloads/logstash/logstash-7.17.0-linux-x86_64.tar.gz解压：[root@VM-24-17-centos opt]# tar -xvf logstash-7.17.0-linux-x86_64.tar.gz                                                                                        

备份：

配置：

input {file {type => "docker"path => "/var/lib/docker/containers/*/*.log"start_position => "beginning"sincedb_path => "/dev/null"codec => "json"}
}
output {elasticsearch {hosts => ["localhost:9200"]index => "docker-%{+YYYY.MM.dd}"document_type => "docker"}
}

#启动logstash:

cd /opt/logstash-7.17.0 && 
./bin/logstash -f config/docker.conf &

———————附录：本机mac m1 安装kibana-----------

本机再启动一个kibana实例：

jelex@jelexxudeMacBook-Pro ~ % docker run --name kibana-tencent -e ELASTICSEARCH_HOSTS=http://101.43.xxx.xx -p 5602:5601 -d arm64v8/kibana:7.17.5
430b2c038fd79c41dca524bcd2dfc58452bbc9f770166b2d6ece1b5e2b2eacab
jelex@jelexxudeMacBook-Pro ~ % docker ps | grep kibana
430b2c038fd7   arm64v8/kibana:7.17.5     "/bin/tini -- /usr/l…"   10 seconds ago       Up 9 seconds        0.0.0.0:5602->5601/tcp                                 kibana-tencent
jelex@jelexxudeMacBook-Pro ~ %

GET _analyze
{
“text”: “hello,world 徐…”
}

————#添加认证：————

# 配置X-Pack
http.cors.enabled: true
http.cors.allow-origin: "*"
http.cors.allow-headers: Authorization
xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true

#重启es:

#设置es密码：

[root@VM-24-17-centos dockerV]# docker exec -it ES01 bash
root@1701f055dbb0:/usr/share/elasticsearch/bin# ./elasticsearch-setup-passwords interactive 

kibana配置认证：
jelex@jelexxudeMacBook-Pro ~ % docker exec -it kibana-tencent bash

#把配置文件复制出来：

jelex@jelexxudeMacBook-Pro ~ % docker cp kibana-tencent:/usr/share/kibana/config /Users/jelex/Desktop

#删除容器：重新来，加上配置卷映射：

#把桌面上刚从容器中复制出来的配置文件放到容器卷中：

编辑配置：认证

docker run --name kibana-tencent -e ELASTICSEARCH_HOSTS=http://101.43.xxx.xx -p 5602:5601 -v /Users/jelex/dockerV/kibana-tencent/config:/usr/share/kibana/config -d arm64v8/kibana:7.17.5

访问kibana:http://localhost:5602/login?next=%2Fapp%2Fdev_tools#/console

#输入elastic / xxxx密码 用户名和密码：注意：用户名不是kibana
此时顶部就没有未认证warning了：

logstash加入认证：

#杀死原来的进程，重新启动：
cd /opt/logstash-7.17.0 && ./bin/logstash -f config/docker.conf &

#如果不行，再试试：

xpack.monitoring.enabled: true
xpack.monitoring.elasticsearch.username: xxxxusername
xpack.monitoring.elasticsearch.password: xxxxxpwd
xpack.monitoring.elasticsearch.hosts: ["http://localhost:9200"]
