LeoFS升級

前言

目前我們所使用的LeoFS圖床伺服器為1.0.0版本，因應目前遇到的幾個Bug，需進行版本升級。
目前最新的版本為1.2.1。我們即以此版本作為升級目標。

升級計畫

因最新版本不再提供我們目前使用的OS版本(Ubuntu 12.04)的deb package，
我們會透過自己預先Build好的leofs-1.2.1.tar.gz進行系統升級。

升級步驟

1. 升級Leofs manager node
   
   • Stop manager_1

     # cd ~
     # leo_manager_1/bin/leo_manager stop
     

   • Stop manager_0

     # cd ~
     # leo_manager_0/bin/leo_manager stop
     

   • Update manager_0

     # cd /usr/local/leofs
     # tar zxvf leofs-1.2.1.tar.gz
     # cp -R 1.0.0/leo_manager_0/work 1.2.1/leo_manager_0/
     # nano 1.2.1/leo_manager_0/etc/leo_manage.conf
     # cd ~
     # unlink leo_manager_0
     # ln -s /usr/local/leofs/1.2.1/leo_manager_0 leo_manager_0
     # leo_manager_0/bin/leo_manager start
     

   • Update manager_1

     # cd /usr/local/leofs
     # tar zxvf leofs-1.2.1.tar.gz
     # cp -R 1.0.0/leo_manager_1/work 1.2.1/leo_manager_1/
     # nano 1.2.1/leo_manager_1/etc/leo_manage.conf
     # cd ~
     # unlink leo_manager_1
     # ln -s /usr/local/leofs/1.2.1/leo_manager_1 leo_manager_1
     # leo_manager_1/bin/leo_manager start
     

2. 升級Leofs storage node
   
   • Suspend one of storage nodes

     # telnet $(mgt0_ip) 10010
     # status
     # suspend $(node)
     

   • Stop storage node

     # cd ~
     # leo_storage/bin/leo_storage stop
     

   • Update storage

     # cd /usr/local/leofs
     # tar zxvf leofs-1.2.1.tar.gz
     # cp -R 1.0.0/leo_storage/work 1.2.1/leo_storage/
     # nano 1.2.1/leo_storage/etc/leo_storage.conf
     # cd ~
     # unlink leo_storage
     # ln -s /usr/local/leofs/1.2.1/leo_storage leo_storage
     # leo_storage/bin/leo_storage start
     

   • resume storage

     # telnet $(mgt0_ip) 10010
     # status
     # resume $(node)
     

   • Continues Update other storage nodes with steps
3. 升級Leofs Gateway node
   
   • Stop leo_gateway

     # cd ~
     # leo_gateway/bin/leo_gateway stop
     

   • Update gateway

     # cd /usr/local/leofs
     # tar zxvf leofs-1.2.1.tar.gz
     # cp -R 1.0.0/leo_gateway/work 1.2.1/leo_gateway/
     # nano 1.2.1/leo_gateway/etc/leo_gateway.conf
     # cd ~
     # unlink leo_gateway
     # ln -s /usr/local/leofs/1.2.1/leo_gateway leo_gateway
     # leo_gateway/bin/leo_gateway start
