想不通的救援模式，黑进服务器？

想不通的救援模式 朋友们，请教一个问题： 拿到实体服务器后，如果忘记Linux 服务器的root密码，我们可以进入救援模式，进行密码修改。那这种操作，我们是不是对于任何一台服务器，就算不知道密码，然后通过救援模式进去设置一个密码，然后就可以进入到系统了？ 问题问得有点蠢，我一时想不通，求求朋友们指点下...🦆 /轻喷

axios全局设置了自定义的header后，每一个请求头部应该都带有自定义的header信息吗？

使用vue+Axios+ThinkPHP实现一个用户登录的简易登录系统, 下图 "https://wmprod.oss-cn-shanghai.aliyuncs.com/community/1724816941408_guvy.png" (https://wmprod.oss-cn-shanghai.aliyuncs.com/community/1724816941408_guvy.png) 后台获取header中的数据是保存，获取不到 "https://wmprod.oss-cn-shanghai.aliyuncs.com/community/1724816955781_KXUZ.png" (https://wmprod.oss-cn-shanghai.aliyuncs.com/community/1724816955781_KXUZ.png) 错误提示 "https://wmprod.oss-cn-shanghai.aliyuncs.com/community/1724816965094_OtiC.png" (https://wmprod.oss-cn-shanghai.aliyuncs.com/community/1724816965094_OtiC.png) 不应该是每一个ajax请求的Request Header里面都会添加一个键值对吗， 想这样的 authKey:ADKJAHSDJKAHSDJKASDHIUWEIUWHDSADUIAS 为什没有呢 "https://wmprod.oss-cn-shanghai.aliyuncs.com/community/1724816975871_pksz.png" (https://wmprod.oss-cn-shanghai.aliyuncs.com/community/1724816975871_pksz.png) "https://wmprod.oss-cn-shanghai.aliyuncs.com/community/1724816981074_UVMJ.png" (https://wmprod.oss-cn-shanghai.aliyuncs.com/community/1724816981074_UVMJ.png)

如何解决Django项目自带venv虚拟环境无法激活的问题？

想问一下，为什么不能激活我Django项目里面自带的venv虚拟环境？ [root@web-s2 venv]# source /srv/opt/djangoProject1/venv/bin/activate -bash: /srv/opt/djangoProject1/venv/bin/activate: 没有那个文件或目录 https://wmprod.oss-cn-shanghai.aliyuncs.com/c/user/20240924/d889e3700d648f4adc2a704dc0c0586f.png 查询是否存在该路径，可以查到，但执行命令还是不成功 我希望在不新建虚拟环境的情况下，可以告诉我该如何解决这一问题，使其可以使用项目里面自有的虚拟环境。

如何在CentOS 7.9上安装Node.js的高版本(18以上)?

centos7.9安装nodejs18以上版本的优选方案? 前言 有个项目是nuxt2做的(node版本16.14.0),现在准备使用nuxt3重构(node 20.10.0),而使用nuxt3需要node至少18.0.0(此处吐槽nuxt3中文网坑爹提示需要node版本16.0.0) 安装node20.10.0 使用centos7.9安装node20.10.0,运行node提示 [dev1@localhost bin]$ ./node -v ./node: /lib64/libm.so.6: version GLIBC_2.27' not found (required by ./node) ./node: /lib64/libc.so.6: version GLIBC_2.25’ not found (required by ./node) ./node: /lib64/libc.so.6: version GLIBC_2.28' not found (required by ./node) ./node: /lib64/libstdc++.so.6: version CXXABI_1.3.9’ not found (required by ./node) ./node: /lib64/libstdc++.so.6: version GLIBCXX_3.4.20' not found (required by ./node) ./node: /lib64/libstdc++.so.6: version GLIBCXX_3.4.21’ not found (required by ./node) 发现需要升级GLIBC,而升级GLIBC的前置条件是需要升级 gcc 和make. 在网上查了一下,由于CentOS 7.9 默认仓库提供的GCC版本可能相对较低，因为这个版本的系统主要是为了稳定性考虑，通常不会包含最新的开发工具链。CentOS 7.9 默认安装的GCC版本是4.8.x系列,make是3.几. 由于线上的生产环境是已经稳定运行了一段时期了,而升级node所需的依赖都涉及到核心库,可能存在一些风险和不可预测的后果,无法预测,请教各位大神,有没有比较好的方案

CentOS 怎么导出如软件？

"CentOS" 怎么导出如软件？比如 "nginx" "git" 因为有的部署场景是内网的，所以我想先本地安装好然后导出来再拷贝到服务器上安装，并且如果可以的话这样的导出会把依赖一起导入进去么？
