泄露秘密 提交于 2021-02-08 12:10:13
问题 Though there are many tutorials online on how to make a cross compiler, I am actually not getting it. I am using fedora 16 and already have gcc installed. I am not sure about binutils . How do I make a cross compiler for my own OS (the target) ? I was reading here on os dev wiki but I don't get it. I mean, what do I do ? I just don't follow there steps. Note : I want to build a cross compiler for the same architecture I am currently working on.I mean the same architecture that is running

问题 I want to create mysql dumps for a database which is running in docker container. However I do not want to get into the container and execute the command but do it from the host machine. Is there a way to do it. I tried few things but probably I am wrong with the commands. docker exec -d mysql sh mysqldump -uroot -pSomePassword DBName > /dumps/MyNewDump.sql docker exec -d mysql sh $(mysqldump -uroot -pSomePassword DBName > /dumps/MyNewDump.sql) docker exec -d mysql mysqldump -uroot

问题 I recently set up Fedora 33 and was migrating over my files. I copied over my ssh keys and found that I could no longer pull from bitbucket git repos I was able to pull from on my old laptop. The ssh keys are exactly the same, and the public key is already on the bitbucket account. Additionally the permissions were set to chmod 600 . I still can not pull from the repo. 回答1: This seems to be a recent issue around Fedora 33. This is the relevant bug report. The issue is that it seems like

In fedora container systemctl gives Failed to get D-Bus connection

元气小坏坏 提交于 2021-02-04 19:47:06
问题 When I in a fedora container systemctl use, I get: Failed to get D-Bus connection:: Unknown error -1 Does someone know how to fix this? Or can systemctl not be used in a docker container? 回答1: The systemctl command talks to systemd over a DBus connection. It is unlikely that you are running systemd in your container, so systemctl has nothing with which to talk. While it is possible to run systemd in a container, doing so is often (but not always!) a sign that you need to rethink the

使用 Ansible 的第一天

一名系统管理员分享了如何使用 Ansible 在网络中配置计算机并把其带入实际工作的信息和建议。 无论是第一次还是第五十次,启动并运行一台新的物理或虚拟计算机都非常耗时,而且需要大量的工作。多年来,我一直使用我创建的一系列脚本和 RPM 来安装所需的软件包,并为我喜欢的工具配置各种选项。这种方法效果很好,简化了我的工作,而且还减少了在键盘上输入命令的时间。 我一直在寻找更好的工作方式。近几年来,我一直在听到并且读到有关 Ansible 的信息,它是一个自动配置和管理系统的强大工具。Ansible 允许系统管理员在一个或多个剧本playbook中为每个主机指定一个特定状态,然后执行各种必要的任务,使主机进入该状态。这包括安装或删除各种资源,例如 RPM 或 Apt 软件包、配置文件和其它文件、用户、组等等。 因为一些琐事,我推迟了很长一段时间学习如何使用它。直到最近,我遇到了一个我认为 Ansible 可以轻松解决的问题。 这篇文章并不会完整地告诉你如何入门 Ansible,相反,它只是对我遇到的问题和我在一些隐秘的地方发现的信息的做了一些记录。我在各种在线讨论和问答小组中找到的有关 Ansible 的许多信息都是错误的。错误范围包括明显的老旧信息(没有任何日期或来源的迹象),还有一些是完全错误的信息。 本文所介绍的内容是有用的,尽管可能还有其它方法可以完成相同的事情,但我使用的是

Linux系统介绍、常用命令及演用练习

1.1 Linux系统介绍 GUN,GPL,LGPL介绍 GNU计划,又称革奴计划,是由Richard Stallman在1983年9月27日公开发起的。它的目标是创建一套完全自由的操作系统 GPL协议的主要内容是只要在一个软件中使用("使用"指类库引用,修改后的代码或者衍生代码)GPL 协议的产品,则该软件产品必须也采用GPL协议,既必须也是开源和免费。 LGPL 是GPL的一个为主要为类库使用设计的开源协议。和GPL要求任何使用/修改/衍生之GPL类库的的软件必须采用GPL协议不同。LGPL允许商业软件通过类库引用(link)方式使用LGPL类库而不需要开源商业软件的代码。这使得采用LGPL协议的开源代码可以被商业软件作为类库引用并发布和销售。 Linux特性介绍 开放性是指系统遵循世界标准规范,特别是遵循开放系统互连(OSI)国际标准。凡遵循国际标准所开发的硬件和软件,都能彼此兼容,可方便地实现互连。 多用户是指系统资源可以被不同用户各自拥有使用,即每个用户对自己的资源(例如:文件、设备)有特定的权限,互不影响。 多任务是现代计算机的最主要的一个特点。它是指计算机同时执行多个程序,而且各个程序的运行互相独立。 Linux向用户提供了两种界面:用户界面和系统调用。Linux的传统用户界面是基于文本的命令行界面,即shell,它既可以联机使用,又可存在文件上脱机使用
