在Apache上执行Julia;设置APPDATA和家庭环境变量

标签： apache julia ampps

我正在尝试在Apache上的浏览器中执行Julia代码（我在Windows 10上使用Ampps）。我能够执行它真正的命令提示符或通过python代码调用它（请参阅下面的python代码）。当我尝试直接在浏览器上执行Julia代码时，我得到网关超时服务器没有及时响应消息。但是当我尝试执行调用Julia代码的python代码时，我会在Apache的错误日志中获得更详细的信息：

这似乎是一个与如何在Julia中设置APPDATA env变量相关的已知问题。 Here，建议应在httpd.conf或httpd-vhosts.conf中设置HOMEDRIVE，HOMEPATH和APPDATA的env变量。我试过编辑httpd-vhosts.conf和httpd.conf，但我仍然得到同样的错误。

这就是我编辑httpd.conf的方式：

#### Localhost VirtualHost ####

<VirtualHost 127.0.0.1:80>
<Directory "{$path}/www">
    Options Indexes FollowSymLinks ExecCGI
    AddHandler cgi-script .cgi .py .jl
    AllowOverride All
    Order deny,allow
    allow from All
</Directory>
SetEnv HOMEDRIVE "C:"
SetEnv HOMEPATH "/Users/Reza"
SetEnv APPDATA "C:/Users/Reza/AppData/Roaming"
ScriptLog logs/julia_cgi.log
ServerName localhost
ServerAlias localhost 127.0.0.1
ScriptAlias /cgi-bin/ "{$path}/www/cgi-bin/"
DocumentRoot "{$path}/www"
ErrorLog "{$path}/apache/logs/error.log"
CustomLog "{$path}/apache/logs/access.log" combined
</VirtualHost>

这是调用Julia代码的python代码：

#!"C:/Python27/ArcGIS10.3/python.exe"

import subprocess

print "Content-Type: text/html\n\n"
print "hi there! this is python!"

command="C:/Users/Reza/AppData/Local/Julia-0.5.1/bin/julia.exe"
path2script="C:/Program Files (x86)/Ampps/www/csvToLayer_JSAPI/HT.jl"
cmd = [command, path2script]

x = subprocess.check_output(cmd)

print x

这是朱莉娅代码：

#!"C:/Users/Reza/AppData/Local/Julia-0.5.1/bin/julia.exe"
redirect_stderr(STDOUT)
println("Content-Type: text/html\n\n")
println("hi there; this is Julia!");
println("Julia is passing outputs to Python");

我是否为APPDATA env变量设置了一个wroge位置？我应该为APPDATA使用什么文件夹？除了“C：/ Users / Reza / AppDate / Roaming”之外，我还尝试了“C：/ Users / Reza / AppDate / Local”和“C：/Users/Reza/AppDate/Local/Julia-0.5.1” ，我得到同样的错误。

1 个答案:

答案 0 :(得分：1)

我不知道为什么SetEnv在httpd.conf中不起作用，但我找到了一个解决方法。我在Python中设置了环境变量：

#!"C:/Python27/ArcGIS10.3/python.exe"
import subprocess,os

print "Content-Type: text/html\n\n"
print "hi there! this is python!"

os.environ["HOMEDRIVE"]="C:"
os.environ["HOMEPATH"]="/Users/Reza"
os.environ["APPDATA"]="C:/Users/Reza/AppData/Roaming"

command="C:/Users/Reza/AppData/Local/Julia-0.5.1/bin/julia.exe"
path2script="C:/Program Files (x86)/Ampps/www/csvToLayer_JSAPI/HT.jl"
cmd = [command, path2script]

try:
    print subprocess.check_output(cmd)
except subprocess.CalledProcessError as e:
    print e.output
