当数据库跑了较长时间后，存储的数据将越来越多，这时候往往也意味着，一旦数据库服务器出现宕机等相关状况，将给我们的业务带来巨大的影响，甚至可能是具备一定的毁灭性的，因此，即使对数据库进行备份是极其重要的。接下来，我们一起来学习全量备份的实现方式。

Python本身自带了一套工具distutils ，用于发布 Python 应用程序。但 distutils 没有提供定义其它依赖包的功能，setuptools 的真正优点并不在于实现distutils 所能实现的功能——尽管它的确增强了distutils的功能并简化了setup.py 脚本中的内容。setuptools 最大的优势是它在包管理能力方面的增强。它可以使用一种更加透明的方法来查找、下载并安装依赖包；并可以在一个包的多个版本中自由进行切换，这些版本都安装在同一个系统上；也可以声明对某个包的特定版本的需求；还可以只使用一个简单的命令就能更新到某个包的最新版本。 简单来说，Python setuptools可以看做是增强版的distutils，用来管理Python的各种包。

PSSH提供OpenSSH和相关工具的并行版本。包括pssh，pscp，prsync，pnuke和pslurp。该项目包括psshlib，可以在自定义应用程序中使用。 pssh是python写的可以并发在多台机器上批量执行命令的工具，它的用法可以媲美ansible的一些简单用法，执行起来速度比ansible快它支持文件并行复制，远程命令执行，杀掉远程主机上的进程等等。杀手锏是文件并行复制，，当进行再远程主机批量上传下载的时候，最好使用它。 项目地址: https://code.google.com/archive/p/parallel-ssh/

最近需要使用django搭建一个网站，使用的数据库是mysql。 mac电脑里面已经安装好了mysql-5.7-community。 之前使用的python和mysql的链接模块是Pymysql，使用django-11.3版本的时候没有需要问题。但是重新更新了django到2.0，下载好之前的配置后（requests），运行程序发现这个问题：
安装好之后，可以使用命令conda，可以使用一系列命令参数，conda --help 或 conda -h 、 conda --version 或 conda -V

Podman 是一个开源的容器运行时项目，可在大多数 Linux 平台上使用。Podman 提供与 Docker 非常相似的功能。正如前面提到的那样，它不需要在你的系统上运行任何守护进程，并且它也可以在没有 root 权限的情况下运行。 Podman 可以管理和运行任何符合 OCI（Open Container Initiative）规范的容器和容器镜像。Podman 提供了一个与 Docker 兼容的命令行前端来管理 Docker 镜像。
直接用pip install django命令安装可能会报错，用下面的命令就不会报错了：

新的GC分为Pause, Copying, Reclaim三个阶段，以Region为单位进行GC。
本文进入我们进入 JVM 调优系列 2，GC 如何判断对象是否为垃圾，这个是面试中的高频面试题，同时对于 GC 的三色标记算法属于 GC 算法的核心内容，我们将通过算法的应用原理进行深度剖析并分析存在的问题，由此来得出 GC 的制定机制是什么？这里就不再强调重点了，因为到处都是重点！
今天是一个难忘的日子，当时本来想清除主机上面data目录下的mysql8.0相关的数据文件的，进入mysql8.0的数据文件所在路径下，结果在执行rm -rf ./data/* 时打成了rm -rf /data/* ，一个回车下去，结果就悲剧了。整个/data目录下的所有文件全部删除了，瞬间奔溃了，真是欲哭无泪，索性之前主机做了快照备份的，立即回滚快照。
