初步学习Angular9，在httpclient模块栽了半天。根据官方文档设置ur居然是无效的，比如 1 2 let httpParams = new HttpParams().set('code', 'aaaa');//可以成功设置code httpParams.set('state', 'ccccc'); // 无法设置state 看了stackoverflow的回答后才知道 HttpParams旨在是不可变的。该set和append方法不修改现有的实例。相反，它们返回新实例并应用更改。 所以这里有两种方案: 1、使用 fromString 变量从查询字符串中直接创建 HTTP 参数 1 2 3 4 5 const data = { code: this.subInfo.code, state: this.subInfo.state }; const httpParams = new HttpParams({fromObject: data}); 2、直接传递对象而不是HttpParams 1 http.get(url, {params: data}) 所以直接是用方法2了~ 参考文章: https://stackoverflow.com/questions/45210406/angular-4-3-httpclient-set-params

最近在学es，需要导入8亿条数据 手上有一个txt大约有8亿条数据的样子，文件有19G左右，一开始百度搜了下，基本都是重复文章，不过也根据写这些文章的大佬慢慢google到了一些方法。 先说下导入机器配置: cpu: E5 1620V2 内存: 32G(分给es 12G) 硬盘:4x2T raid 0(io大概在600左右) 导入的几种方法: 1、bulk: ES本地支持的批量导入方式，将json文件post到es进行处理。 将需要导入的数据先生成json文件，格式类似这种 1 2 3 4 5 6 7 8 9 #指定 index {"index":{"_index":"suoy","_id":1}} #字段 {"text_entry":"内容"} {"index":{"_index":"suoy","_id":1}} {"text_entry":"内容"} {"index":{"_index":"suoy","_id":1}} {"text_entry":"内容"} ........... 然后使用curl提交 1 curl -H 'Content-Type: application/x-ndjson' -XPOST '127.0.0.1:9200/xxxxxxxx/doc/_bulk?pretty' --data-binary @out.json 一开始我是尝试这种方法，用python将数据重新处理了下，生成的文件有48GB……，还花了3-5个小时的样子，导入的时候直接失败~后面，看了下说是文件大小尽量不能超过200MB???这样的话就要分割文件了，虽然可以shell脚本一个一个的提交小文件json，后面想想直接放弃了（嫌麻烦）……. 2、logstash： ES官方的另一个产品，将数据文本转换为ES的数据源。 我的文本一行只有两个字段，用 “—-” 分割，花了点时间学logstash直接上手开干，但是导入速度只有9000条/s的样子，一个小时导了大概3200w条数据，导了16个小时大概导了5.2亿条数据，这速度完全不行啊，后面手贱不注意按了 Ctrl+c，嗯…..这下好了，不知道怎么断点续传，又得重新来…… 我用的脚本如下，有懂的大佬能否告知下logstash有没有类似BulkProcessor储存到x条数据再执行Bulk的方法? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 input { # 从文件读取日志信息 file { path => "/data/sda3/k/log.txt" type => "text" start_position => "beginning" } } filter { mutate { split => ["message", "----"] } if [message][2] { mutate { add_field => { "title" => "%{[message][1]}" "log" => "%{[message][2]}" } } }else{ if [message][0] { mutate { add_field => { "title" => "%{[message][0]}" } } } if [message][1] { mutate { add_field => { "log" => "%{[message][1]}" } } } } } output { elasticsearch{ hosts => "127.0.0.1:9200" index => "logs" user => "elastic" #password => "xxx" #document_type => "_doc" } # 标准输出 #stdout { codec => rubydebug } } ...

其实安装完pve后第一步就是移除企业订阅源，防止后面出现很多问题(由于企业仓库更新源需要购买订阅服务，所以我们需要手动修改到官方的非订阅源)。 由于proxmox VE 的 ifupdown2 到企业版里了，所以…… 删除原来的企业源 1 rm /etc/apt/sources.list.d/pve-enterprise.list 添加官方非订阅免费源 1 echo 'deb http://download.proxmox.com/debian/pve buster pve-no-subscription' >> /etc/apt/sources.list.d/pve-no-subscription.list 注意上边的buster，非其他教程中的stretch，是由于debian版本的问题，具体不解释 更新 1 apt update 安装ifupdown2 1 apt install ifupdown2 参考文章: https://www.d3tt.com/view/119

注册完E5后可以绑定自己的域名作为邮局，但是只有默认的onmicrosoft.com域开启了DKIM，自己接入的域名并没有开启，所以这里按照官方文档开启DKIM以减少进垃圾邮箱的可能性。 2021-12-04 更新 有读者反馈 https://security.microsoft.com/dkimv2 网址已经可以直接开启DKIM了，我去试了下，点击开启会自动校验 CNAME 记录，自己复制值在dns那添加就可以了(如果不知道怎么添加，可以看第三步)。 以下文章仅作记录，直接通过上面的方法开启就可以了。 1、开启DKIM 首先进入到office365管理面板，点击左侧菜单栏的「全部显示」，然后点击「Exchange」，进入Exchange控制台。 这里会列出已接入域名，点击域名右侧会显示DKIM的状态，点击启用就好。 如果第一次接入会显示「没有为此域名保存DKIM签名 」，根据官方文档，可以通过Powershell方式来开启。 2、连接到 Exchange Online 这里的操作以管理员权限打开，需要注意的是，所有命令必须在同一个PowerShell下操作 。 下面命令中 为自己的域名 。 在本地计算机上，打开 Windows PowerShell 并运行以下命令。 1 $UserCredential = Get-Credential 在“Windows PowerShell 凭据请求”对话框中，键入工作或学校帐户用户名和密码，再单击“确定”。 运行以下命令连接到Exchange Online： 1 $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection 注意： 对于 Office 365 世纪互联运营，请使用 ConnectionUri 值：https://partner.outlook.cn/PowerShell 对于 Office 365 Germany，请使用 ConnectionUri 值：https://outlook.office.de/powershell-liveid/ 对于 Microsoft 365 GCC High，请使用 ConnectionUri 值：https://outlook.office365.us/powershell-liveid/ 对于 Microsoft 365 DoD，请使用 ConnectionUri 值：https://webmail.apps.mil/powershell-liveid 运行以下命令设置会话： 1 Import-PSSession $Session -DisableNameChecking ...

如果是自己的域名在反代配置加上这2句就可以了。 1 2 proxy_ssl_name $host; proxy_ssl_server_name on; 我自己的配置是 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 location / { proxy_pass https://域名; #Proxy Settings proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_ssl_name $host; proxy_ssl_server_name on; proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504; # proxy_max_temp_file_size 0; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 64k; proxy_buffers 32 32k; proxy_busy_buffers_size 128k; proxy_temp_file_write_size 64k; }

https://blog.curlc.com/archives/595.html 这台机器买来后idrac有一个问题，只要断电，idrac的密码就会被恢复为上一次设置的密码.如果在bios重置密码也会被“永久”的设置成calvin这个默认密码。 所以特别蛋疼，每次断电开机完就得修改密码，在dell社区问过一次，答复居然是“一般服务器是不会断电”，真的是无语了…… 昨天由于折腾ssl把idrac搞挂了，这次断电也没有恢复，就进bios重置了idrac(恢复出厂设置)后居然就好了，断电密码被“重置”这个问题也就没了，但是我记得有一次我也重置过，但是没用，总之，这是一个奇葩的问题~
