问题：magento2.4的站点，执行 bin/magento indexer:reindex 后，elastic search 报错。内容如下：

Catalog Search index process error during indexation process:
{"error":{"root_cause":[{"type":"cluster_block_exception","reason":"index [magento2_mazia_243_product_1_v45] blocked by: [TOO_MANY_REQUESTS/12/disk usage exceeded flood-stage watermark, index has read-only-allow-delete block];"}],"type":"cluster_block_exception","reason":"index [magento2_mazia_243_product_1_v45] blocked by: [TOO_MANY_REQUESTS/12/disk usage exceeded flood-stage watermark, index has read-only-allow-delete block];"},"status":429}

尝试：按网上说的，调整elastic search设置后就可以了：

curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_cluster/settings -d '{ "transient": { "cluster.routing.allocation.disk.threshold_enabled": false } }'

curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'

需求：想将magento2的static和media配置cdn，如aws的cloudfront访问。

尝试：

1. 分别以/static和/media为源，在cloudfront创建两个分配
2. 如/static的分配，在“行为”中的“源请求策略名称”选择为“Managed-CORS-CustomOrigin”、“响应标头策略名称”选择为“Managed-CORS-With-Preflight”
3. 在magento2后台中，设置static和media的网址为cloudfront的
4. 如需调整static和media文件目录中的.htaccess内容，可适当调整

现象：通过magento 1.x 自带的导出商品数据功能，再在迁移后的站点里导入，商品丢失价格等部分属性。如果直接通过mysqldump导出及mysql导入整个magento站点数据表，则站点后台无法列出显示商品，“商品管理”为零。

尝试：在phpmyadmin中看到，通过mysql导入数据库内容后的部分数据表，如 catalog_product_entity_int 无数据。尝试通过phpmyadmin导入该表时，提示错误 #1062 - Duplicate entry '204-102-0' for key 'UNQ_CATALOG_PRODUCT_ENTITY_INT_ENTITY_ID_ATTRIBUTE_ID_STORE_ID' 。很可能是因为原数据库的部分数据表有错误，无法成功导出完整的数据。

需求：如果想将wordpress站点的目录移到magento1.x的子目录，通过magento的URL来访问，应该怎么做呢？

尝试：需要修改相应的静态化规则。如nginx的，可参考这个：https://docs.ukfast.co.uk/ecommercestacks/magento/magento1/wpinsubdir.html

现象：在magento 1.9里安装Magento-SMTP-Pro-Email-Extension扩展后，无法使用gmail账号发出邮件。用命令测试连接smtp服务器，提示用户名或密码不可接受。535-5.7.8 Username and Password not accepted. Learn more at https://support.google.com/mail/?p=BadCredentials b4sm2793148pga.69 - gsmtp

尝试：登录到gmail账户，设置允许安全性较低的应用访问帐号。之后再次测试，就可以了。
