DCOS Cassandra - 用非root用戶運行cassandraDemon

Question

我想用非root用戶在dcos中運行cassandraDemon。就像在cassandra在dcos上安裝時一樣，我想把service.user改成。 我們該怎麼做？

Answer 1

假設core存在於代理的用戶，你會做這樣的：

$ cat options.json 
{ 
    "service": { 
    "user": "core" 
    } 
} 

$ dcos package install --options=options.json cassandra
