自建Elasticsearch 迁移至阿里云Elasticsearch

📌 一、阿里云官方文档核心要求（已全部落实）

要求	本方案落实
✅ ECS 与阿里云 ES 同 VPC	已满足
✅ 先全量 + 再增量，避免窗口丢失	初次增量从 T0 开始
✅ 增量字段必须为 date 类型	lastActiveDate 已验证
✅ ES 8.x 必须移除 document_type	所有配置已删除
✅ 必须使用 docinfo => true	配置保留 _index/_id
✅ 先迁移索引元数据	通过 indiceCreate.py 实现
✅ 首次增量手动验证，再启用 schedule	初次配置注释 schedule

📁 二、全部脚本文件（共 5 个）

1️⃣ 检查脚本：check_bc_indices.sh

#!/bin/bash
SOURCE_HOST="https://1.1.1.1:9200"
SOURCE_USER="elastic"
SOURCE_PASS="wanyanzhenjiang"
TARGET_HOST="http://2.2.2.2:9200"
TARGET_USER="elastic"
TARGET_PASS="wanyanzhenjiang"

echo "【1/3】获取源集群统计..."
curl -k -u "$SOURCE_USER:$SOURCE_PASS" -s "${SOURCE_HOST}/_cat/indices/bc_*?h=index,docs.count" | sort > /tmp/source.txt

echo "【2/3】获取目标集群统计..."
curl -u "$TARGET_USER:$TARGET_PASS" -s "${TARGET_HOST}/_cat/indices/bc_*?h=index,docs.count" | sort > /tmp/target.txt

echo "【3/3】差异对比（无输出 = 一致）："
diff /tmp/source.txt /tmp/target.txt

echo ""
echo "📊 源文档总数：$(awk '{sum+=$2} END{print sum+0}' /tmp/source.txt)"
echo "📊 目标文档总数：$(awk '{sum+=$2} END{print sum+0}' /tmp/target.txt)"

权限：chmod +x check_bc_indices.sh

---

2️⃣ 清理脚本：clean_bc_indices.sh

#!/bin/bash
TARGET_HOST="http://2.2.2.2:9200"
TARGET_USER="elastic"
TARGET_PASS="wanyanzhenjiang"

indices=$(curl -u "$TARGET_USER:$TARGET_PASS" -s "${TARGET_HOST}/_cat/indices/bc_*?h=index" | tr '\n' ',' | sed 's/,$//')
if [ -z "$indices" ]; then echo "⚠️ 无 bc_* 索引"; exit 0; fi

curl -u "$TARGET_USER:$TARGET_PASS" -XPOST -s "${TARGET_HOST}/${indices}/_close" >/dev/null
resp=$(curl -u "$TARGET_USER:$TARGET_PASS" -XDELETE -s "${TARGET_HOST}/${indices}")

if [[ "$resp" == *"acknowledged\":true"* ]]; then
  echo "✅ 清理完成"
else
  echo "❌ 失败：$resp"; exit 1
fi

权限：chmod +x clean_bc_indices.sh

---

3️⃣ 索引元数据迁移脚本：indiceCreate.py

#!/usr/bin/env python3
import json, requests
from urllib3.exceptions import InsecureRequestWarning
requests.packages.urllib3.disable_warnings(category=InsecureRequestWarning)

SOURCE_HOST = "https://1.1.1.1:9200"
SOURCE_USER = "elastic"
SOURCE_PASS = "wanyanzhenjiang"
TARGET_HOST = "http://2.2.2.2:9200"
TARGET_USER = "elastic"
TARGET_PASS = "wanyanzhenjiang"
DEFAULT_REPLICAS = 1

def get_indices():
    r = requests.get(f"{SOURCE_HOST}/_cat/indices/bc_*?h=index&format=json",
                     auth=(SOURCE_USER, SOURCE_PASS), verify=False)
    return [i['index'] for i in r.json()]

def get_meta(idx):
    settings = requests.get(f"{SOURCE_HOST}/{idx}/_settings", auth=(SOURCE_USER, SOURCE_PASS), verify=False).json()
    mapping = requests.get(f"{SOURCE_HOST}/{idx}/_mapping", auth=(SOURCE_USER, SOURCE_PASS), verify=False).json()
    return {
        "settings": {
            "number_of_shards": int(settings[idx]['settings']['index']['number_of_shards']),
            "number_of_replicas": DEFAULT_REPLICAS
        },
        "mappings": mapping[idx]['mappings']
    }

def create_index(idx, body):
    r = requests.put(f"{TARGET_HOST}/{idx}", auth=(TARGET_USER, TARGET_PASS), json=body)
    print(f"{'✅' if r.status_code in (200, 201) else '❌'} {idx}")

if __name__ == "__main__":
    for idx in get_indices():
        create_index(idx, get_meta(idx))
    print("\n🎉 索引元数据同步完成！")

依赖：pip3 install requests

4️⃣ T0 时间注入脚本：generate_incremental_config.sh

#!/bin/bash
T0_FILE="/tmp/T0.txt"
TEMPLATE_FILE="es2es_incremental_template.conf"
OUTPUT_FILE="es2es_incremental_initial.conf"

if [ ! -f "$T0_FILE" ]; then
  echo "❌ $T0_FILE 不存在！格式：2025-12-17T01:42:14Z"
  exit 1
fi

T0=$(cat "$T0_FILE" | tr -d '[:space:]')
if [[ ! "$T0" =~ ^[0-9]{4}-[0-9]{2}-[0-9]{2}T[0-9]{2}:[0-9]{2}:[0-9]{2}Z$ ]]; then
  echo "❌ T0 格式错误！应为 UTC（如 2025-12-17T01:42:14Z）"
  exit 1
fi

cat > "$TEMPLATE_FILE" <<EOF
input {
  elasticsearch {
    hosts => ["https://1.1.1.1:9200"]
    user => "elastic"
    password => "wanyanzhenjiang"
    index => "bc_*"
    query => '{"query": {"range": {"lastActiveDate": {"gte": "T0_PLACEHOLDER", "lte": "now"}}}}'
    # 首次运行：注释下一行
    # schedule => "*/5 * * * *"
    docinfo => true
    docinfo_target => "[@metadata]"
    size => 5000
    scroll => "5m"
    slices => 1
    ssl_verification_mode => "none"
  }
}

filter {
  mutate {
    remove_field => ["@timestamp", "@version"]
  }
}

output {
  elasticsearch {
    hosts => ["http://2.2.2.2:9200"]
    user => "elastic"
    password => "wanyanzhenjiang"
    index => "%{[@metadata][_index]}"
    document_id => "%{[@metadata][_id]}"
    ilm_enabled => false
    manage_template => false
    ssl_verification_mode => "none"
  }
}
EOF

sed "s/T0_PLACEHOLDER/$T0/g" "$TEMPLATE_FILE" > "$OUTPUT_FILE"
echo "✅ 生成初次增量配置：$OUTPUT_FILE"

权限：chmod +x generate_incremental_config.sh

---

5️⃣ 全量迁移配置：es2es_full.conf

input {
  elasticsearch {
    hosts => ["https://1.1.1.1:9200"]
    user => "elastic"
    password => "wanyanzhenjiang"
    index => "bc_*"
    docinfo => true
    docinfo_target => "[@metadata]"
    size => 5000
    scroll => "5m"
    slices => 4
    ssl_verification_mode => "none"
  }
}

filter {
  mutate {
    remove_field => ["@timestamp", "@version"]
  }
}

output {
  elasticsearch {
    hosts => ["http://2.2.2.2m:9200"]
    user => "elastic"
    password => "wanyanzhenjiang"
    index => "%{[@metadata][_index]}"
    document_id => "%{[@metadata][_id]}"
    ilm_enabled => false
    manage_template => false
    ssl_verification_mode => "none"
  }
}

---

🔹 三、两套完整增量配置（无省略）

A. 初次增量配置（es2es_incremental_initial.conf）

用途：全量完成后首次运行，覆盖窗口数据
T0：2025-12-17T01:42:14Z
注意：必须注释 schedule 手动运行

input {
  elasticsearch {
    hosts => ["https://1.1.1.1:9200"]
    user => "elastic"
    password => "wanyanzhenjiang"
    index => "bc_*"
    query => '{"query": {"range": {"lastActiveDate": {"gte": "2025-12-17T01:42:14Z", "lte": "now"}}}}'
    # schedule => "*/5 * * * *"
    docinfo => true
    docinfo_target => "[@metadata]"
    size => 5000
    scroll => "5m"
    slices => 1
    ssl_verification_mode => "none"
  }
}

filter {
  mutate {
    remove_field => ["@timestamp", "@version"]
  }
}

output {
  elasticsearch {
    hosts => ["http://2.2.2.2:9200"]
    user => "elastic"
    password => "wanyanzhenjiang"
    index => "%{[@metadata][_index]}"
    document_id => "%{[@metadata][_id]}"
    ilm_enabled => false
    manage_template => false
    ssl_verification_mode => "none"
  }
}

---

B. 常规增量配置（es2es_incremental_routine.conf）

用途：长期后台运行
频率：每 5 分钟

input {
  elasticsearch {
    hosts => ["https://1.1.1.1:9200"]
    user => "elastic"
    password => "wanyanzhenjiang"
    index => "bc_*"
    query => '{"query": {"range": {"lastActiveDate": {"gte": "now-5m", "lte": "now"}}}}'
    schedule => "*/5 * * * *"
    docinfo => true
    docinfo_target => "[@metadata]"
    size => 5000
    scroll => "5m"
    slices => 1
    ssl_verification_mode => "none"
  }
}

filter {
  mutate {
    remove_field => ["@timestamp", "@version"]
  }
}

output {
  elasticsearch {
    hosts => ["http://2.2.2.2:9200"]
    user => "elastic"
    password => "wanyanzhenjiang"
    index => "%{[@metadata][_index]}"
    document_id => "%{[@metadata][_id]}"
    ilm_enabled => false
    manage_template => false
    ssl_verification_mode => "none"
  }
}

🚀 四、完整操作流程（10 步）

1. 准备 T0

   echo "2025-12-17T01:42:14Z" > /tmp/T0.txt
   

2. 清理目标

   ./clean_bc_indices.sh
   

3. 创建索引

   python3 indiceCreate.py
   

4. 验证目标为空

   ./check_bc_indices.sh
   

5. 全量迁移（前台）

   cd /home/admin/packages/logstash
   bin/logstash -f config/es2es_full.conf
   

6. 验证全量一致

   ./check_bc_indices.sh  # 应无输出
   

7. 生成初次增量配置

   ./generate_incremental_config.sh
   

8. 手动运行初次增量

   bin/logstash -f config/es2es_incremental_initial.conf
   

9. 切换为常规增量

   • 将 es2es_incremental_initial.conf 重命名为 es2es_incremental_routine.conf
   • 注释 T0 行，启用 now-5m 行
   • 取消注释 schedule

10. 后台启动常规增量

    nohup bin/logstash -f config/es2es_incremental_routine.conf > incremental.log 2>&1 &

✅ 五、最终验证

• 文档数一致：./check_bc_indices.sh 无输出
• 内容一致：

  curl -u elastic:wanyanzhenjiang 'http://es-cn-.../bc_user_v1/_search?q=id:337451'
