FreeBSD 更新和升级

保持系统更新!

FreeBSD 系统更新​

FreeBSD提供了两种更新系统方式:

  • freebsd-update 命令用于更新核心系统
  • 包管理器或 ports系统 ( ports Collection ) 用于更新第三方软件

FreeBSD 系统升级​

提示

恰逢6月10日FreeBSD发布了最新的 RELEASE-14.3 ，所以我准备借此实践将原本 RELEASE-14.2 到升级 RELEASE-14.3

  • 在执行 系统升级 前，先完成前文所述的 系统更新 ，确保 当前RELEASE 是最新:
freebsd-update fetch install
  • RELEASE-14.2 到升级 RELEASE-14.3 :
freebsd-update -r 14.3-RELEASE upgrade

此时输出信息:

src component not installed, skipped
Looking up update.FreeBSD.org mirrors... 3 mirrors found.
Fetching metadata signature for 14.2-RELEASE from update1.freebsd.org... done.
Fetching metadata index... done.
Fetching 1 metadata files... ^[done.
Inspecting system... done.

The following components of FreeBSD seem to be installed:
kernel/generic world/base

The following components of FreeBSD do not seem to be installed:
kernel/generic-dbg world/base-dbg world/lib32 world/lib32-dbg

Does this look reasonable (y/n)? y
