KaraDAV is a lightweight, PHP‑based WebDAV server that lets you manage files and folders through a web interface. While Nextcloud offers extensive features, KaraDAV provides a 10x lighter solution perfect for resource-constrained hosts like Lolipop.jp. In this post, we’ll walk through installing KaraDAV on a Lolipop! rental server. We’ll follow the instructions from the KaraDAV repository’s INSTALL.md file and adapt them for a shared hosting environment where you likely manage your site via a control panel and FTP.

As mentioned in a previous blog post, my current project is deployed using Docker. However, during a recent login to the server, a strange phenomenon occurred: all the containers in Docker would restart from time to time. Also, every time I logged in to check the Docker status, it would show that the containers had just started (Up 15 seconds). After several investigations, I finally identified that the restart issue was related to SSH login. Every time I logged in via SSH, the containers would restart.

After three months of hard work, the SSL certificate of my RSS aggregator finally expired. The auto-renew script failed to renew it — this happened a couple of times, I need to login into the web panel and renew it manually every three months. Unfortunately, the web panel malfunctioned this time either. After an epic battle with cert-bot, Nginx, and even the web panel I used, I finally gave up and decided to switch to another self-hosting solution.

普通用户如何设置SSH密钥访问
普通用户建立SSH密钥实现无密码登陆
VPS操作中更加推荐使用普通用户登录SSH(避免root远程登陆)，但直接设置会造成权限问题（尤其是之前配置过root用户使用密钥认证）。本文简单介绍普通用户配置SSH密钥访问的方法，具体原理请参加末尾参考部分。
首先建立普通用户并设置密码（推荐使用密码生成工具生成高强度密码）
建立用户
useradd lxfy
生成密码
passwd lxfy
随后在root身份下创立普通用户ssh文件夹
mkdir -m 777 /home/lxfy/.ssh
切换回普通用户，并生成公钥私钥。
略~
导入公钥到authorized_keys
cat id_rsa.pub > authorized_keys
修改权限
chmod 600 ~/.ssh/authorized_keys
删除公钥私钥
rm -rf id_rsa.pub rm -rf id_rsa
重启SSH服务即可~
