CentOS 环境配置文件的语法

我正在尝试修改 CentOS 7 上的文件 /etc/sysconfig/httpd。

此文件修改了systemd下httpd服务的环境。

我想通过添加来修改 PATH 变量。我可以设置它，但我在寻找正确的语法来添加它。

如果我使用这个：

PATH="/export/home/www/perl5/bin:$PATH"

..那么我在 Apache 上的 PATH 中得到的内容实际上是：

/export/home/www/perl5/bin:$PATH

换句话说，它没有插入 $PATH 变量。

我尝试了许多不同的语法，但仍然无法让它发挥作用。

有人知道正确的语法吗？

答案1

设置 Environment= 时，systemd 不支持变量扩展。解决方法是只说明您需要设置的完整路径集。

否则，您粘贴的内容/etc/sysconfig/httpd看起来对过渡到 Apache 有很好的建议，由systemd

答案2

man /etc/sysconfig/httpd

#  # This file is no longer used to configure additional environ‐
ment variables # for the httpd process.  # # It has been replaced
by systemd. If you want to customize, the best # way is to create
a file "/etc/systemd/system/httpd.service", # containing #   .in‐
clude  /lib/systemd/system/httpd.service #   ...make your changes
here...   #  For  more  info  about  custom  unit  files,  see  #
http://fedoraproject.org/wiki/Systemd#How_do_I_custom‐
ize_a_unit_file.2F_add_a_custom_unit_file.3F


# To set OPTIONS environment variable which was set in this  file
# in older versions, you need to create a file named # "/etc/sys‐
temd/system/httpd.service" containing: #       .include /lib/sys‐
temd/system/httpd.service  #       [Service]  #       # #       #
To pass additional options (for instance, ‐D definitions) to  the
#       #  httpd  binary at startup, set OPTIONS here.  #       #
#       Environment=OPTIONS=‐DMY_DEFINE

# Note: With previous versions of httpd, the MPM could be changed
by # editing an "HTTPD" variable here.  With the current version,
that # variable is now ignored.  The MPM is  a  loadable  module,
and  the # choice of MPM can be changed by editing the configura‐
tion file # /etc/httpd/conf.modules.d/00‐mpm.conf.  #

这是来自 fedora 23，但我确信它足够相似，可以给你指点，否则请在你的机器上自己运行“man /etc/systemd/httpd”。
