現在很多 Linux 套件都需要 systemd 來管理跟啟動服務. 由於 WSL2 是 Ｗindows 下的一個 VM , 所以微軟實作了一個init (PID 1) 來做到快速啓動 WSL VM 以及作為與 windows 溝通的橋樑. 可以執行systemctl 確認是否有 systemd

  1. [root@dev workspace]# systemctl
  2. System has not been booted with systemd as init system (PID 1). Can't operate.
  3. Failed to connect to bus: Host is down
  4. [root@dev workspace]#

所幸, GitHub 上已經有幾個專案可以直接拿來建構有systemd(PID 1)環境, 這裡我們使用
DamionGans/ubuntu-wsl2-systemd-script, 只要按照說明操作就可以了

  1. [root@dev workspace]# cp -f /mnt/d/Projects/Github/linux/ubuntu-wsl2-systemd-script/ubuntu-wsl2-systemd-script.sh /root/workspace
  2. [root@dev workspace]# ls
  3. golang  hello.c   test.sh
  4. hello   Makefile  ubuntu-wsl2-systemd-script.sh
  5. [root@dev workspace]# chmod +x ubuntu-wsl2-systemd-script.sh
  1. [root@dev workspace]# bash ubuntu-wsl2-systemd-script.sh

恭喜!!接近完整的Linux更近一步囉

  • Exit the WSL terminal and shutdown the WSL env:

    1. PS C:\Users\Administrator> wsl --shutdown

  • To open a new WSL terminal with systemd enabled, run:

    1. PS C:\Users\Administrator>wsl genie -s

  • Prove that it works:

    1. [root@dev workspace]# sudo systemctl status time-sync.target
