linux-为所有用户附加LD_LIBRARY_PATH

[英]linux - Append LD_LIBRARY_PATH for all users

原文 2014-02-18 15:54:47 1 2 linux

I need to append a few paths to my LD_LIBRARY_PATH variable. 我需要为LD_LIBRARY_PATH变量添加一些路径。 This is very simple to do on a per user basis by adding export LD_LIBRARY_PATH=... to my ~/.bashrc file. 通过将export LD_LIBRARY_PATH=...添加到我的~/.bashrc文件中，这对于每个用户而言非常简单。 However, I would like to have this added for all users. 但是，我想为所有用户添加此功能。

Is there a place I can add the export LD_LIBRARY_PATH=... so that the environment variable will be appended for all users? 是否可以添加export LD_LIBRARY_PATH=...以便将环境变量附加到所有用户？

Thanks! 谢谢！

You can add the path to /etc/ld.so.conf . 您可以将路径添加到/etc/ld.so.conf 。

If this is about third party software in a non-standard install path, you may want to look at the stow utility instead, which is a symlink farming helper that will help you catch name conflicts between installed software. 如果这是关于非标准安装路径中的第三方软件的，则您可能需要查看stow实用程序，它是一个symlink耕作助手，可帮助您捕获已安装软件之间的名称冲突。

You can add it to the global /etc/profile, but this may not be the solution you are looking for. 您可以将其添加到全局/ etc / profile中，但这可能不是您想要的解决方案。 LD_LIBRARY_PATH has some pitfalls, such as being dropped for setuid binaries and not being indexed by the ld.so cache. LD_LIBRARY_PATH有一些陷阱，例如被setuid二进制文件删除并且未被ld.so高速缓存索引。

If you just want to add global system-wide library paths, the correct place to do them is in the /etc/ld.so.conf file which is just a list of directories. 如果只想添加系统范围的全局库路径，则正确的位置是/etc/ld.so.conf文件，该文件只是目录列表。 after you add to it, be sure to run 'ldconfig' as root to scan the new directories. 添加到它之后，请确保以root用户身份运行“ ldconfig”以扫描新目录。
