<title>Environment Variables</title>
|
|
|
|
<para>To use Nix, some environment variables should be set. In
|
|
particular, <envar>PATH</envar> should contain the directories
|
|
<filename><replaceable>prefix</replaceable>/bin</filename> and
|
|
<filename>~/.nix-profile/bin</filename>. The first directory contains
|
|
the Nix tools themselves, while <filename>~/.nix-profile</filename> is
|
|
a symbolic link to the current <emphasis>user environment</emphasis>
|
|
(an automatically generated package consisting of symlinks to
|
|
installed packages). The simplest way to set the required environment
|
|
variables is to include the file
|
|
<filename><replaceable>prefix</replaceable>/etc/profile.d/nix.sh</filename>
|
|
in your <filename>~/.profile</filename> (or similar), like this:</para>
|
|
|
|
<screen>
|
|
source <replaceable>prefix</replaceable>/etc/profile.d/nix.sh</screen>

<section xml:id="sec-nix-ssl-cert-file">

|
<title><envar>NIX_SSL_CERT_FILE</envar></title>
|
|
|
|
<para>If you need to specify a custom certificate bundle to account
|
|
for an HTTPS-intercepting man in the middle proxy, you must specify
|
|
the path to the certificate bundle in the environment variable
|
|
<envar>NIX_SSL_CERT_FILE</envar>.</para>
|
|
|
|
|
|
<para>If you don't specify a <envar>NIX_SSL_CERT_FILE</envar>
|
|
manually, Nix will install and use its own certificate
|
|
bundle.</para>
|
|
|
|
<procedure>
|
|
<step><para>Set the environment variable and install Nix</para>
|
|
<screen>
|
|
$ export NIX_SSL_CERT_FILE=/etc/ssl/my-certificate-bundle.crt
|
|
$ curl https://nixos.org/nix/install | sh
|
|
</screen></step>
|
|
|
|
<step><para>In the shell profile and rc files (for example,
|
|
<filename>/etc/bashrc</filename>, <filename>/etc/zshrc</filename>),
|
|
add the following line:</para>
|
|
<programlisting>
|
|
export NIX_SSL_CERT_FILE=/etc/ssl/my-certificate-bundle.crt
|
|
</programlisting>
|
|
</step>
|
|
</procedure>
|
|
|
|
<note><para>You must not add the export and then do the install, as
|
|
the Nix installer will detect the presense of Nix configuration, and
|
|
abort.</para></note>

<title><envar>NIX_SSL_CERT_FILE</envar> with macOS and the Nix daemon</title>
|

<para>On macOS you must specify the environment variable for the Nix
|
|
daemon service, then restart it:</para>

$ sudo launchctl setenv NIX_SSL_CERT_FILE /etc/ssl/my-certificate-bundle.crt
