FreeNAS

发表于由

 Two TrueNAS (FreeNAS)  NAS system are setup for the purpose of data backup, including the resumed blog running on ESXi virtual machine, replaced the Buffalo lS-WXL and WdMycloud.

The benefit of FreeNAS:

  • Based on Freebsd OS, stable
  • Native support ZFS, and snapshot
  • Other professional feature ready

 

The blog data is backup into the 1st FreeNAS, manually after updating the blog.

The 1st FreeNas will generate a snapshot every day, thanks to the Periodic Snapshot Task provided by FreeNAS system, and them replicate the snapshot to the 2nd FreeNas machine, also thanks to the Replication Task of freeNas system.

 

Hardware spec of 1st NAS:

  1. HP T610 plus thin client  ( AMD (G-T56N) 1.65GHz dual core / E350 )
  2. 16GB DDR3  (2 X 8GB)
  3. 32GB Flash driver  for FreeNAS system + 4TB 3.5 HD for data
  4. 10/100/1000  Ethernet

 

    Cost: without Data Disk:

             AMD T610 Plus                               RMB 185
             Power：19V4.74  7.4*5.0mm         RMB 30
             SATA2 32G SSD                            RMB 45
             DDR3L 8G/1600  X2                       RMB 398
———————————————————————–
                 Total                                            RMB 658      

 

 

Hardware spec of 2st NAS:

  1. HP Z220 MT workstation
  2. 32GB DRR3 ECC RAM
  3. Intel G3250T CPU
  4. One USB key for FreeNAS system + 10T HD for data

 

The Raid sub-system is not a best choice.

As Home User, we don’t care about the data lost, or data server down in a short period of time.  That’s way we two NAS system / Data replication instead of raid sub-system.

 

 

 

 

 

Linux Application From Scratch

发表于由

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)
