Apache 2: calling 'a2ensite' from a bash script in Linux
提问by Gabi Barrientos
I am currently writing an admin page for my webserver, to make it easier on myself to create new apache domains from my browser. Everything is pretty much working as I want it to, except for one thing.
我目前正在为我的网络服务器编写一个管理页面，以便我自己更轻松地从我的浏览器创建新的 apache 域。除了一件事，一切都如我所愿。
To elaborate: I have a cron job on my server running a bash script as root that checks a file containing a list of domain names that I want to be created. If the file contains a domain name, it automatically creates a new virtual host for this domain, edits my hosts file, and restarts the server. This all works perfectly, however what I would like for the script to do, is that it activates the domain that it automatically creates before it restarts the server. I tried doing this using apache 2's a2ensitecommand, however the script returns an error saying the command is not found.
详细说明：我的服务器上有一个 cron 作业，它以 root 身份运行 bash 脚本，该脚本检查包含我要创建的域名列表的文件。如果文件包含域名，它会自动为这个域创建一个新的虚拟主机，编辑我的主机文件，并重新启动服务器。这一切都很完美，但是我希望脚本做的是，它在重新启动服务器之前激活它自动创建的域。我尝试使用 apache 2 的a2ensite命令执行此操作，但是脚本返回一个错误，指出找不到该命令。
Is there a way to call this command from a bash script, or is there an alternative to this command that I can call?
有没有办法从 bash 脚本调用这个命令，或者我可以调用这个命令的替代方法？
Any help would be greatly appreciated.
任何帮助将不胜感激。

$ which a2ensite
/usr/sbin/a2ensite
Usually, cron has a quite restrictive $PATH, not including /usr/sbinor /sbin, which are system binaries (for use by root). It's always a good idea to use fully qualified path names. So either call /usr/bin/a2ensitein your script, or define a variable:
通常，cron 有一个非常严格的 $PATH，不包括/usr/sbin或/sbin，它们是系统二进制文件（供 root 使用）。使用完全限定的路径名总是一个好主意。所以要么调用/usr/bin/a2ensite你的脚本，要么定义一个变量：
A2ENSITE=/usr/sbin/a2ensite
...
${A2ENSITE} new-domain.com
