capistrano deploy_symlink失败 [英] capistrano deploy_symlink fails
问题描述
这是我的第一次部署。我做了一个上限 deploy：setup ，效果很好。
This is my first deployment. I did a cap deploy:setup which worked fine.
然后，当我尝试执行 cap deploy：update 我遇到了错误消息。类似于
Then, when I try to execute cap deploy:update I run into error messages. Something along the lines of
rm: cannot remove `/var/www/app_name/current': Is a directory
这是我的capfile和目录权限。
Here is my capfile and directory permissions.
< a href = http://pastie.org/1189919 rel = nofollow> http://pastie.org/1189919
，就部署用户和权限而言，最佳实践是什么？我应该使用root还是创建其他用户。如果其他用户需要什么确切权限？
In general, what is the best practice as far as deployment user and permissions are concerned? Should I use root or create a different user. If a different user what exact permissions does it need?
谢谢
推荐答案
您是在 / var / www / app_name 中创建目录还是由capistrano创建的？
Did you create the directories within /var/www/app_name, or were they created by capistrano?
无论如何，您遇到的问题是 / var / www / app_name / current 不应该是目录-它应该是 / var / www / app_name / releases / 中完成新发行文件夹的创建并尝试对 / var进行符号链接时，导致失败/ www / app_name / current 。
Regardless, the issue you have is that /var/www/app_name/current should not be a directory - it should be a symlink to the current release within /var/www/app_name/releases/. The failure is caused when capistrano has finished creating the new release folder within /var/www/app_name/releases/, and is trying to symlink /var/www/app_name/current to it.
您也许可以通过重命名 / var /来解决问题www / app_name / current （以便在出现问题时进行备份），并从 / var / www / app_name / current 创建符号链接到 / var / www / app_name / releases / 中的最新版本，然后进行 cap部署。 （如果可行，请删除当前的备份。）
You might be able to fix your issues by renaming /var/www/app_name/current (so you have a backup if things go wrong), and creating a symlink from /var/www/app_name/current to the most recent release within /var/www/app_name/releases/, and then doing a cap deploy. (Delete your backup of current if this works).
就最佳实践而言，请勿使用root 。而是设置仅对所需目录具有权限的用户（或使用现有用户）（不会仔细阅读脚本，而可能只是 / var / www / app_name 。
As far as best practice goes whatever you do, do not use root. Instead, set up a user (or use an existing user) that has only permissions to the required directories (didn't read your scripts closely, but probably just /var/www/app_name.
