win10 wsl ubuntu无法使用 systemctl命令解决!!!!!!!!!!!问题情况：执行systemc

问题情况：执行systemctl命令后出现

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

安装 daemonize和fontconfig

apt install -y fontconfig daemonize
编辑/etc/profile脚本，加入如下内容

SYSTEMD_PID= $(ps -ef | grep '/lib/systemd/systemd --system-unit=basic.target$ ' | grep -v unshare | awk '{print $2}')

if [ -z " $SYSTEMD_PID" ]; then sudo /usr/bin/daemonize /usr/bin/unshare --fork --pid --mount-proc /lib/systemd/systemd --system-unit=basic.target SYSTEMD_PID=$ (ps -ef | grep '/lib/systemd/systemd --system-unit=basic.target $' | grep -v unshare | awk '{print$ 2}') fi

if [ -n " $SYSTEMD_PID" ] && [ "$ SYSTEMD_PID" != "1" ]; then exec sudo /usr/bin/nsenter -t $SYSTEMD_PID -a su -$ LOGNAME fi
修改/etc/sudoers文件，加入如下内容:

%sudo ALL=(ALL) NOPASSWD: /usr/sbin/daemonize /usr/bin/unshare --fork --pid --mount-proc /lib/systemd/systemd --system-unit=basic.target %sudo ALL=(ALL) NOPASSWD: /usr/bin/nsenter -t [0-9]* -a su - [a-zA-Z0-9]*

执行 source /etc/profile

完美解决
