先自我介绍一下，小编浙江大学毕业，去过华为、字节跳动等大厂，目前阿里P7

深知大多数程序员，想要提升技能，往往是自己摸索成长，但自己不成体系的自学效果低效又漫长，而且极易碰到天花板技术停滞不前！

因此收集整理了一份《2024年最新Linux运维全套学习资料》，初衷也很简单，就是希望能够帮助到想自学提升又不知道该从何学起的朋友。

既有适合小白学习的零基础资料，也有适合3年以上经验的小伙伴深入学习提升的进阶课程，涵盖了95%以上运维知识点，真正体系化！

由于文件比较多，这里只是将部分目录截图出来，全套包含大厂面经、学习笔记、源码讲义、实战项目、大纲路线、讲解视频，并且后续会持续更新

如果你需要这些资料，可以添加V获取：vip1024b （备注运维）

## 为了方便使用，将12版本的数据库安装包打了一个一键化安装的tar包


* 


### 已将一键化安装包上传至下载论坛：


[CentOS7.4系统下一键安装postgresql-12.3版本数据库]( )


**安装时注意：**  
 1、输入目录最后不用加 / (斜杠)  
 2、第一个数据入的是安装目录（home）  
 3、第二个数据入的是数据存放目录(data)
