在ChatGPT的帮助下我有了以下脚本：

#/bin/bash
# 设置Cloudflare的API密钥、电子邮件地址和区域ID
api_key=""
email=""
zone_identifier=""
record_identifier=""

# 设置要更新的DNS记录的信息

record_name="aaa.example.com"
proxied=false
record_type="AAAA"
comment="IPv6 update"
#以IPv6为例
ipv6_address=""

curl --request PUT \
    --url "https://api.cloudflare.com/client/v4/zones/${zone_identifier}/dns_records/${record_identifier}" \
    --header 'Content-Type: application/json' \
    --header "X-Auth-Email: ${email}" \
    --header "X-Auth-Key: ${api_key}" \
    --data "{
    \"content\": \"${new_ipv6_address}\",
    \"name\": \"${record_name}\",
    \"proxied\": ${proxied},
    \"type\": \"${record_type}\",
    \"comment\": \"${comment}\"
}"

其中的空项大都可以通过登录CloudFlare查询到。需要注意的是record_identifier一项，它也需要通过api获取：

将yoursite.com域名下的所有路径均反向代理到localhost:8080:

server {
        root /var/www/html;
    server_name yoursite.com;

    location / {
        proxy_pass http://localhost:8080;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_redirect off;
    }
#ssl settings
}

将根路径代理到localhost:8080而将/web02代理到localhost:18080：

Use TestDisk and PhotoRec to recover photos in SDXC card, and it works, perfectly.

Change the base url of in Nginx as follows:

    location /01/ {
        alias /var/www/01/;
        index index-01.html;

• Mount a .iso file:

sudo modprobe loop
sudo mount ./something.iso ./mnt

sudo setfacl -m u:jellyfin:rx /home/user
sudo setfacl -x u:jellyfin /home/user

经常需要在Linux命令行中使用代理，大致如下操作：

编辑/home/user/.bashrc，在其中添加形如：

Newly installed an openSUSE system on my ThinkPad X1 Tablet for daily use. BTW Windows runs as shit on it. I noticed that the time of system was incorrect. So...I'm trying solving it by deploying NTP service and run it manually once.

那么简记一下配置过程吧。

不论如何，请首先参阅 官方文档。

我的配置思路是：

• Run nginx service at server side, and set the web root to a certain dictionary such as /var/www/blog/.

當我使用 nginx 對 localhost:8080 进行反向代理时，收到 503 响应。检查 nginx error log，发现有：

[crit] 10000#0: *3 connect() to 127.0.0.1:8080 failed (13: Permission denied) while connecting to upstream, client: ***, server: ***, request: "GET /x/ HTTP/1.1", upstream: "http://127.0.0.1:8080/", host: "***"

经过检查，发现是 SELinux 策略阻止了 nginx 访问 上游接口。

Nextcloud is installed via snapcraft.

snap run nextcloud.occ config:system:get trusted_domains 1

snap run nextcloud.occ config:system:delete trusted_domains

snap run nextcloud.occ config:system:set trusted_domains 1 --value=www.example.com

Update

It seems that the linux .run file we were using in this article below is no longer provided by Bitnami. Sad...

WordPress usually requires a LAMP(Linux, Apache, MySQL, PHP) or LNMP environment, which is complicated to deploy and migrate. Bitnami provides an easier way to accomplish the jobs above.

Snap provides an approach to install Nextcloud easy and clean.

Prepare a domain name resolved to the IP address of your server.

#Debian\Ubuntu: 

#As super user:

apt install snapd

snap install nextcloud

#Enter your domain into browser and you'll see the welcome page, opreate as instruction.

nextcloud.enable-https lets-encrypt

#Operate as instruction.

#Done.

To set nextcloud port different than default:
