如何使用 ad-hoc 命令过滤nocache块或块？free我试过ansible centos1 -m setup -a 'filter=ansible_memory_mb.nocache'了，但没有过滤掉。

我们在 gitlab 上调用了我们的共享库mainlibrary，它有很多 groovy 文件。

在 mainlibrary gitlab repo 中的示例我们有以下文件。

startup_pipeline.groovy
cleanup_pipeline.groovy

在我们的一项 Jenkins 工作中，我们需要在Jenkinsfile. 这可能吗？

这是看起来的Jenkinsfile样子：

@Library('mainlibrary')_
startup_pipeline(email:'[email protected]')

我可以Jenkinsfile像这样将第二个 groovy 函数文件包含在其中吗？

@Library('mainlibrary')_
startup_pipeline(email:'[email protected]'),
cleanup_pipeline(email:'[email protected]')

已授予 GCP VM 使用的默认服务帐户storage.buckets.*和storage.objects.*角色，但我收到storage.buckets.create未设置权限的错误。

拒绝：项目“test-307504”的令牌交换失败。调用者没有权限“storage.buckets.create”。要配置权限，请按照以下说明操作： https ://cloud.google.com/container-registry/docs/access-control

默认服务帐户是[email protected]，我创建了与存储相关的角色并分配给 IAM 服务帐户，然后我运行了命令gcloud auth configure-docker。但我仍然无法将 docker 图像推送到 GCR 存储库。

在分配要在 VM 上刷新的角色后，我还应该做些什么吗？

log4j.properties 和 logging.properties 有什么区别？

我应该修改哪一个以将应用程序日志记录到 catalina.2021.01.01？

现在 docker 镜像只记录 tomcat 启动日志，catalina.2021.01.01但应用程序日志的其余部分打印到控制台。

这是当前设置

1catalina.org.apache.juli.FileHandler.level = FINE
1catalina.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
1catalina.org.apache.juli.FileHandler.prefix = catalina.

我正在尝试将其配置为应用程序以记录它catalina.2021.01.01和 tomcat 启动日志catalina.out。

Gitlab push 很慢，有没有我可以在内部 gitlab-ce 服务器上修改的设置，可以让 git push 更快？现在的push速度是13.00 KiB/s。

由于 gitlab 的速度，我有一些大型 repo 仍然没有提交给它。

设置git config http.postBuffer 524288000卡在POST git-receive-pack (37437584 bytes)很长时间。

设置git config http.postBuffer 5242开始推动，但速度非常低。

`Writing objects:  76% (73/95), 3.72 MiB | 13.00 KiB/s`

我读到这git config http.postBuffer并没有使它更快，因为只有本地缓冲区更快，但推送仍然取决于服务器接受速度。所以想知道是否可以在服务器端进行任何调整？

如何确定为每个应用程序部署分配多少最小和最大资源？我正在建立一个集群，但我没有设置任何资源并让它自由运行。

我想我可以用top command它来计算高峰时间的负载并进行处理，但仍然顶部说 6% 或 10% 但我不知道如何计算它们以产生类似0.5 cpuor的东西100 MB。是否有根据top command使用情况确定最大值和最小值的方法/公式？

我正在运行两个 t3.medium 节点，并且我有以下 pod httpd and tomcat in namespace1、mysql in namepsace2、jenkins and gitlab in namespace3。是否有关于它需要的最低资源的指南？还是我必须根据顶部或其他方法来计算它？

我确定它在一个月前就可以工作，从那以后就没有尝试过。

C:\Users\Username>cd G:\ /d

Amazon SES 免费套餐每月有 62000 封免费电子邮件。我想知道我是否创建了一个免费层 ec2 实例并在其上使用 SES 并有资格获得每月 62000 封免费电子邮件？我想让 EC2 实例作为中继，以便我的其他非 aws 实例可以使用 ec2 实例发送电子邮件？

这是允许的还是可能的？如果可能的话，我想我也需要为我的 ec2 实例购买一个静态弹性 IP，对吗？因为我希望 ec2 成为其他非 AWS 主机的中继。

如何javax.servlet在 Teamcity 中导入？当我尝试通过 teamcity IntelliJ IDEA 运行器构建 java 项目时，出现以下错误消息。

这是我第一次使用 teamcity，我正在使用这个https://github.com/marekbruchaty/SimpleJavaWebApp项目。我有一个具有 teamcity 和 gitlab 的 CentOS 服务器。

在我的桌面上，使用 IntelliJ IDEA 我可以导入 servlet.api 来成功构建。但是 teamcity 在另一个位置并远程管理，我想知道如何将 servlet-api 导入到 teamcity 中？

我应该在哪里添加 servlet-api.jar 作为 teamcity 中的依赖项以便它可以编译？

我应该删除磁盘的重要文件，然后启动到活动磁盘并运行dd命令，还是可以继续运行dd而/dev/sda无需删除？

我问这个是因为我已经开始跑步了dd if=/dev/urandom of=/dev/sda bs=1M。只是为了安全起见，我有点知道这两种方式都一样，但想知道是否dd会对已删除的文件或尚未删除的文件造成更大的损害。我可以重新启动dd command，但只需要确认。

我有一个关于安全删除的问题。SDAx 是 ext4，SDA5 是根。

我可以dd if=/dev/urandom of=/dev/sda bs=4096在通过 ssh 或控制台连接到服务器时运行吗？或者我需要有一个 live boot cd 才能做到这一点？或者也许我只能销毁 /dev/sda5 ？

这 3 个命令之间有什么区别 - 我应该使用哪个命令来安全地销毁数据，使其无法恢复。

dd if=/dev/urandom of=/dev/sda bs=4096

dd if=/dev/random of=/dev/sda

dd if=/dev/zero of=/dev/sda

我有 2 个子控制器。但是其中一个控制器可以解析名称，而另一个则不能。我找不到原因。有什么建议可以解决这个问题吗？

编辑：似乎AD_child_02无法解决example.com，但可以解决testserver1.example.com。

AD_child_01可以解决example.com也可以解决testserver1.example.com

AD_child_01 (10.10.10.10) - test1.example.com

AD_child_02 (10.10.10.20) - test1.example.com

使用 AD_child_01 进行测试时：

nslookup test_server 10.10.10.10
Server:  AD_child_01 
Address:  10.10.10.10

Non-authoritative answer:
Name:    test_server
Addresses:  10.10.10.30

使用 AD_child_02 进行测试时：

nslookup test_server 10.10.10.20
Server:  AD_child_02 
Address:  10.10.10.20

我想从服务器中删除 /dev/sdb 磁盘。在此之前，我想我应该删除 lvm 以及与之相关的任何内容。我不关心 /dev/sdb1 数据。

我正在尝试关注这篇文章https://www.golinuxhub.com/2014/03/how-to-remove-logical-and-physical.html

lvremove /dev/mapper/VolGroup01-LogVol00

但在第二个命令期间，我收到以下错误

vgreduce VolGroup01 /dev/sdb1
Can't remove final physical volume "/dev/sdb1" from volume group "VolGroup01"

也试过了vgchange -an VolGroup01 ，然后 vgreduce VolGroup01 /dev/sdb1还是一样的错误。

GPO 未应用，并且在日志中显示它无法访问。但它可以从 \domain.com\sysvol\policies{1C95124D-D9BE-4C67-B9E4-36EDC98DE5BF} 访问。

委派看起来与其他 gpo 相同。关于如何调试问题的任何建议？

对于完全相同的问题，没有谷歌搜索结果。我什至重新创建了 GPO，但仍然遇到同样的错误。

Nagios 不发送电子邮件。我看到它显示警报但没有电子邮件发送的日志。有什么建议可以调试问题吗？

/var/log/maillog 不显示任何日志条目。通过命令行手动发送电子邮件确实会到达我的收件箱。
