在无效组名

Question

我有一个在本地工作的闪亮应用程序，但Shiny Server中存在的版本崩溃了。当我尝试读取日志时，它被分配给组＆＃34; 2111＆＃34;如下面的最后一行所示。问题是我们的系统中没有名称为＆＃34; 2111，＆＃34;它是无效的，我得到了'＃34;许可被拒绝＆＃34;当我试图访问它时。对于每个文件，我的系统管理员可以更改权限，以便我可以读取它们，但是使用无效组＆＃34; 2111＆＃34;创建任何新文件。我必须经历权限再次更改的过程。

如何阻止在无效组＆＃34; 2111下制作日志文件？＆＃34;

作为参考，这是/etc/shiny-server/shiny-server.conf的内容

# Instruct Shiny Server to run applications as the user "shiny"
run_as :HOME_USER: shiny;

# Define a server that listens on port 3838
server {
  listen 3838;

  # Define a location at the base URL
  location / {

# Host the directory of Shiny Apps stored in this directory
site_dir /srv/shiny-server;

# Log all Shiny output to files in this directory
log_dir /var/log/shiny-server;

# When a user visits the base URL rather than a particular application,
# an index of the applications available in this directory will be shown.
directory_index on;
}
}
