  • Blog Migration

    Due to the low internet transfer speed, the blog has been moved from owned-networks vps ( Dallas Texas) to hostus vps of London England.

  • Linux Application From Scratch

    The new wordpress platform is based on Linux Application From Scratch.

    The mysql server, php, nginx (openresty), and all dependency, including gcc and C library, any code in User Space, are build from source code, and installed into /opt/local as root directory.

    The benefit of LAFS (LFS for wordpress application):

    Could be running on any linux platform, as long as same mode (x86-64),  and support the selected basic instruction set (Sandy Bridge). The software is binary compatible,to run it on a new linux machine,  just the copy the image to the /opt/local.

    Thanks to the linux kernel API backword compability,  the kernel version have no side impacts for most of application.

     

    With the help of LAFS implementation, we can build blog platform, modification blog contents locally, and push to the remote public vps with easy:

          Just the file level sync (rsync):

     

    Dev Machine   ==>   Local Production Env   ==>  Remote Public Production Env

      ( Intel E3 )                  ( Vmware ESXi )                         (VPS)
