win10系統中wsl2開啟systemctl命令

默認情況下在wsl2中使用systemctl命令會報錯

$ sudo systemctl status cron.service
System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to bus: Host is down

解決辦法:

1. 安裝daemonize

   sudo apt-get install daemonize
   

2. 執行以下兩句命令開啟

   sudo daemonize /usr/bin/unshare --fork --pid --mount-proc /lib/systemd/systemd --system-unit=basic.target
   
   exec sudo nsenter -t $(pidof systemd) -a su - $LOGNAME
