blocks|key|1420469|text|令人惊讶的是，Unix和Linux实际上没有地方来设置全局环境变量。您所能做的最好的事情就是安排任何特定的shell具有特定于站点的初始化。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1420470|如果将其放在/etc/profile中，就可以满足大多数兼容posix的shell用户的需求。对于非关键目的来说，这可能是“足够好”的。|offset|length|style|CODE|1420471|但是任何拥有csh或tcsh外壳的人都看不到它，而且我不相信csh有一个全局初始化文件。|1420472|entityMap^0|0|6|C|0|6|3|A|4|U|3|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@$D|N|E|O|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|P|8|@$D|Q|E|R|F|G]|$D|S|E|T|F|G]|$D|U|E|V|F|G]]|9|@]|A|$]]|$1|J|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|K|$]]

Amazingly, Unix and Linux do not actually have a place to set global environment variables. The best you can do is arrange for any specific shell to have a site-specific initialization.

If you put it in <code>/etc/profile</code>, that will take care of things for most posix-compatible shell users. This is probably "good enough" for non-critical purposes.

But anyone with a <code>csh</code> or <code>tcsh</code> shell won't see it, and I don't believe <code>csh</code> has a global initialization file.

blocks|key|1205561|text|除了其他人提到的/etc/profile，一些Linux系统现在使用一个目录/etc/profile.d/；其中的任何.sh文件都将由/etc/profile提供。将您的自定义环境内容保存在这些文件中要比只编辑/etc/profile稍微整洁一些。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1205562|entityMap^0|8|C|12|F|1N|3|1V|C|2X|C|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]|$9|M|A|N|B|C]|$9|O|A|P|B|C]|$9|Q|A|R|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|S|8|@]|D|@]|E|$]]]|G|$]]

As well as <code>/etc/profile</code> which others have mentioned, some Linux systems now use a directory <code>/etc/profile.d/</code>; any <code>.sh</code> files in there will be sourced by <code>/etc/profile</code>. It's slightly neater to keep your custom environment stuff in these files than to just edit <code>/etc/profile</code>.

<a href="http://linux.die.net/man/5/pam_env.conf" rel="noreferrer">man 5 pam_env.conf</a>

If all login services use <a href="http://www.kernel.org/pub/linux/libs/pam/" rel="noreferrer">PAM</a>, and all login services have <code>session required pam_env.so</code> in their respective <code>/etc/pam.d/*</code> configuration files, then all login sessions will have some environment variables set as specified in <code>pam_env</code>'s configuration file.

On most modern Linux distributions, this is all there by default -- just add your desired global environment variables to <code>/etc/security/pam_env.conf</code>.

This works regardless of the user's shell, and works for graphical logins too (if xdm/kdm/gdm/entrance/&hellip; is set up like this).

Using PAM is execellent.

If your LinuxOS has this file:

<pre><code>/etc/environment
</code></pre>

You can use it to permanently set environmental variables for all users.
