nginx - 如何在 alpine 中启动 nginx？

Question

我在alpine系统中，并且已经安装了nginx。但是当我尝试启动 nginx 时，出现以下错误:

/run # /etc/init.d/nginx start

 * You are attempting to run an openrc service on a
 * system which openrc did not boot.
 * You may be inside a chroot or you may have used
 * another initialization system to boot this system.
 * In this situation, you will get unpredictable results!
 * If you really want to do this, issue the following command:
 * touch /run/openrc/softlevel
 * ERROR: networking failed to start
 * ERROR: cannot start nginx as networking would not start
/run # 

问题出在哪里？ touch/run/openrc/softlevel 如何帮助解决这种情况？
