• Load Balancing V2Ray Multi-Protocol Multi-Server Setup with HAProxy

  V2Ray's built-in load balancing strategy only offers random selection, which is clearly insufficient for unstable networks.

  ShadowSocks can use HAProxy for load balancing, but V2Ray supports multiple protocols, making this approach impractical.

  We can leverage Docker's features to create a network that uses HAProxy for load balancing while automatically maintaining a list of available nodes (utilizing HAProxy's health check feature and V2Ray's Dokodemo-door).

  NOTE: Almost all code in this article can be copied and used directly, but I strongly recommend reading the comments carefully.

• Converting EXT4 Root Filesystem to XFS (Arch Linux)

  XFS offers more modern features compared to EXT4 and performs better when handling large numbers of files

  References: XFS vs EXT4, Why did CENTOS 7.0 choose XFS as the default filesystem? What are the advantages of XFS over ext?, Ext4 vs XFS – Which one to choose?

  NOTE: Since XFS cannot shrink partitions, it's recommended to use LVM for flexibility

  Prerequisites: Arch Linux system with LVM+EXT4 disk management

  Technical references: Change Root File System from Ext4 to Xfs on Archlinux, XFS (简体中文), LVM (简体中文)

• Installing WordPress with Docker and Quickly Migrating All Data Manually

  Environment selection: Bare metal -> Docker

  Main software choices: NGINX, MariaDB, phpMyAdmin

  Due to MySQL's excessive memory requirements, the original server configuration could no longer support its operation.

  Therefore, purchased a new server configuration on DigitalOcean and decided to deploy using Docker for easier management.

  2. Obtain Docker operation permissions (refer to Docker Wiki):

     sudo groupadd docker
     sudo usermod -aG docker $USER
     

  3. Start Docker service:

     sudo systemctl enable docker
