Ghost nginx 502 ProcessError错误，ghost restart等失效，怎么办？

itlady.com 遇到这个问题

Message: Command failed: /bin/sh -c sudo -S -p '#node-sudo-passwd#'  systemctl is-active ghost_itlady-com

unknown

Exit code: 3


Debug Information:
    OS: linux, v3.10.0-1062.4.1.el7.x86_64
    Node Version: v10.18.1
    Ghost-CLI Version: 1.12.0
    Environment: production
    Command: 'ghost status'

我试过了ghost restart 、ghost doctor、ghost start 等命令都不行，因为进程是正常的

最后在ghost社区遇到一个解决方案，ghost run 解决了。。。。。

The `ghost run` command is used by the configured Ghost process manager and for debugging. If you're not running this to debug something, you should run `ghost start` instead.

补充一下，我是用Centos ，会遇到这类问题，官方推荐用ubuntu，我习惯了centos

sudo systemctl is-active ghost_itlady-com

用这个命令启动ghost，然后用ghost update升级到最新版本

Use ghost run to start Ghost without using the configured process manager. This runs Ghost directly, similar to node index.js.
