Delirium's questions

我试图弄清楚如何格式化大 json 文件并只删除格式如下的证书：

{
  "http-01": {
    "Account": {
      "Email": "[email protected]",
      "Registration": {
        "body": {
          "status": "valid",
          "contact": [
            "mailto:[email protected]"
          ]
        },
        "uri": "https://acme-v02.api.letsencrypt.org/acme/acct/110801506"
      },
      "PrivateKey": "long_key_string",
      "KeyType": "4096"
    },
    "Certificates": [
      {
        "domain": {
          "main": "domain.tld"
        },
        "certificate": "long_cert_string",
        "key": "long_key_String",
        "Store": "default"
      },
      {
        "domain": {
          "main": "domain2.tld"
        },
      .....

我cat acme.json |grep certificate | awk ' { print $1 $2 } '试过了，但我正在努力如何在昏迷之间只选择文本"certificate":和编辑证书。

有没有优雅的方式用 bash/python 格式化它？我找不到办法。

4TB我刚刚从2TBssd添加了更大的md0RAID，但大小仍然相同。我试图调整 .partition 的大小，但它说它很忙。Parted 仍在按旧尺寸调整它的大小。

大批：

Personalities : [raid1] [linear] [multipath] [raid0] [raid6] [raid5] [raid4] [raid10] 
md0 : active raid1 sdb2[3] sda2[2]
      1875210240 blocks super 1.2 [2/2] [UU]
      bitmap: 3/14 pages [12KB], 65536KB chunk

知道我做错了什么吗？谢谢

我在我的主机名上https://servername/phpmyadmin/安装了phpmyadmin。我想更改 url 并“采用”域证书并在其上使用它db.domain.tld，但我无法让它工作。

这是我的 ProxyPass 在ISPConfig主机名中的配置，其中11.22.33.44是服务器 IP 的占位符。

ProxyRequests off
SSLProxyEngine on
ProxyPassReverseCookiePath /phpmyadmin/ /
ProxyPassReverseCookieDomain 11.22.33.44 db.domain.tld

ProxyPass "/" https://11.22.33.44/phpmyadmin/ connectiontimeout=10000 timeout=10000
ProxyPassReverse "/" https://11.22.33.44/phpmyadmin/

这是我在错误日志中得到的错误

我的浏览器中的响应是

如果他们使用 Wordpress，我的营销部门希望我检测我们的域。我有我们庞大的域列表，但我找不到合适的 cms 检测器，它只会将具有 wordpress 的域保存到输出文件中。

我将非常感谢您的建议。

我需要澄清一下。如果我添加此规则

nft add rule ip filter INPUT ip daddr 127.0.0.1 drop

nftables 会忽略它并且永远不会承认，因为它在规则的末尾？

怎么可能创建/dev/sda1和/dev/sda2大小为20GB？我潜伏在谷歌上并尝试过：

Partition type
   p   primary (0 primary, 0 extended, 4 free)
   e   extended (container for logical partitions)
Select (default p): p
Partition number (1-4, default 1): 1

Last sector, +sectors or +size{K,M,G,T,P} (2048-286677119, default 286677119): +size 20G
Last sector, +sectors or +size{K,M,G,T,P} (2048-286677119, default 286677119): 

Created a new partition 1 of type 'Linux' and of size 136.7 GiB.

但它再次以全尺寸创建136.7 GiB。

我需要以某种方式允许我的服务器从自身下载文件。我必须使用wgetfrom example.comon file example.com/script.json，但是当我尝试这样做时，我收到 404 错误

Resolving https://example.com (example.com )... 1.2.3.4
Connecting to example.com (example.com)|1.2.3.4|:443... connected.
HTTP request sent, awaiting response... 404 Not Found
2019-12-04 11:10:50 ERROR 404: Not Found.

文件在目录中/home/site.com/apps/frontend/public

我是否以某种方式为此域设置了 localhost？我觉得我喜欢，但不知道怎么做。

Postfix 正在发送延迟几天的电子邮件。不知道为什么，因为我没有延迟发送设置/etc/postfix/main.cf。它实际上只发生在一个域中。我在服务器上有多个域，只有一个有这个问题。

是否可以将数据从运行的虚拟机内部复制KVM/QEMU到物理主机？

如何创建具有子存储库main, non-free并为其生成key.gpg的本地存储库？

我准备好了文件夹/srv/dists/buster

Input/Output error当我尝试使用qcow2磁盘在我的 KVM 虚拟机上执行某些操作时出现错误。我读到它可能损坏的虚拟磁盘，但我只是在我的管理程序上运行virsh destroy，virsh start现在它工作正常。

我想问是否有可能追踪这个问题的原因，或者是因为系统重启而丢失了证据？

我在 debian9 上运行并使用ppa:ondrej/php存储库，但无法安装 php7.1。也不安装缺少的依赖项。当我尝试安装它时，apt install php7.1-gd我遇到了这个错误。

Varnish 可以为一个站点配置多个后端吗？例如，我有具有多个后端的高可用性站点。

例如，我有www.goodies.com一个在 php 5.6 上运行的站点。所以我有 3 个www-nodes作为后端www-node5.6a www-node5.6b www-node5.6c

我在 Varnish 中配置了这样的后端：

backend www-node5.6a {
    .host = "10.0.0.11";
    .port = "80";
    .connect_timeout = 6000s;
    .first_byte_timeout = 6000s;
    .between_bytes_timeout = 6000s;
}

backend www-node5.6b {
    .host = "10.0.0.12";
    .port = "80";
    .connect_timeout = 6000s;
    .first_byte_timeout = 6000s;
    .between_bytes_timeout = 6000s;
}

backend www-node5.6c {
    .host = "10.0.0.13";
    .port = "80";
    .connect_timeout = 6000s;
    .first_byte_timeout = 6000s;
    .between_bytes_timeout = 6000s;
}

我的问题是，如何配置 Varnish 以便用户将被随机使用到此特定站点的任何后端？

我正在尝试将碰撞上传到 phpmyadmin，它只有 2MB，但它有 12000 行。

我总是收到这个错误：

Service Unavailable
The server is temporarily unable to service your request due to
maintenance downtime or capacity problems. Please try again later.

我有 max_input_time = 1000 max_execution_time = 1000

我在 KVM“machine01”中有虚拟机我有存储/data/sas1/virt/virt.qcow2但未使用/data/sas1/virt/virt2.qcow2

我想通过我的主管上的命令行从/data/sas1/virt/virt.qcow2我/data/sas1/virt/virt2.qcow2的 VirtIO 磁盘源路径更改。那可能吗？

我用这个命令创建了用户并生成了密钥

root# mkdir /usr/share/foreman/.ssh
root# chmod 700 /usr/share/foreman/.ssh
root# chown user:user/usr/share/foreman/.ssh

root# su user -s /bin/bash
user$ ssh-keygen

然后尝试在用户和root之间复制密钥（在同一台服务器上）

user$ ssh-copy-id [email protected]
user$ ssh [email protected]

但是当 tryint to ssh-copy-idroot 要求输入密码时。不知道为什么。

在互联网评论上发现 UsePAM 可以解决这个问题，但对我没有用。

#UsePAM yes

我的 sshd_config 中也有这个选项允许

PasswordAuthentication yes

我正在使用此脚本通过 rsync 备份远程文件。当我尝试启动时出现问题，我得到这个输出错误，我不知道如何处理。感谢您的建议，如果有的话。
