我正在尝试在两个服务器之间同步文件：server1 和 server2 我创建了用户并授予他对 /var/www 上的 RWX 的权限，然后我添加了以下一致配置文件。
root=//var/www/html/
root=ssh://user@server2//var/www/html/environments/simreg/

ignore=Path vendor

但是当我尝试运行一致时，它无法创建备份。调试没有用，我没有意识到我做错了什么。

上面是调试打印。但文件位于两台服务器上
答案1
您的根似乎指定错误。本地路径中的前导双斜杠//var/www/html意味着对远程服务器的引用var，我确信这不是您的意思。试试这些：
root=/var/www/html
root=ssh://user@server2/var/www/html/environments/simreg
根据您的评论，«工件部署在Server1上，然后我们需要将它们复制到Server2上。» 我认为这unison是不适合这项工作的工具。相反，请考虑使用rsync，它提供单向副本：
rsync -av --progress /var/www/html/ user@server2:/var/www/html/environments/simreg/
如果您想测试它而不实际复制任何文件，请包含--dry-run.如果您从批处理作业（cron脚本等）运行它，请删除该--progress标志。
