apache：添加cgi模式

最終指望：經過配置apache的cgi可以使得apache能經過cgi方式鏈接go程序（由於咱們的後端程序是用go語言寫的）。

實驗1：

指望：經過配置cgi使得應用程序可以跑起來。

go代碼：

package main

import "fmt"

func main() {
    fmt.Println("Content-type: text/plain;\n")                                                                                        
    for i, j := 0, 5; i <= j; i, j = i+1, j-1 { //right
        fmt.Println("i=", i, ";j=", j)
    }   

    for i, j := 0, 5; i <= j; i++ { //right
        fmt.Println("i=", i, ";j=", j)
    }   

    //for i,j := 0,5; i <= j; i++, j-- { //wrong
    //    fmt.Println("i=",i,";j=",j)
    //} 
}

Go編譯：/usr/local/go/bin/go build -o /home/luwenwei/go/base/main /home/luwenwei/go/base/for.go

如今就準備好了應用程序。

apache配置：

<VirtualHost *:80>                                                                                                                    
    ServerName api.query.soft.360.cn

    ScriptAlias / /home/luwenwei/go/base/main
    #ScriptAlias /test-cgi /usr/local/apache2/cgi-bin/test-cgi

    <Directory "/usr/local/apache2/cgi-bin/">
        Options -Indexes FollowSymLinks
        AllowOverride None
        Order deny,allow
        Allow from all 
    </Directory>

    ErrorLog logs/error_lww
    CustomLog "|/usr/local/apache2/bin/rotatelogs /usr/local/apache2/logs/lww_access_log.%Y%m%d 86400 480" combinedio
</VirtualHost>

指望訪問 http://api.query.soft.111.cn/ 可以輸出些東西。

輸出：

i= 0 ;j= 5
i= 1 ;j= 4
i= 2 ;j= 3
i= 0 ;j= 5
i= 1 ;j= 5
i= 2 ;j= 5
i= 3 ;j= 5
i= 4 ;j= 5
i= 5 ;j= 5

結果符合預期，實驗1成功。

實驗2：

在apache的bin-cgi目錄下已經有test-cgi應用程序，咱們指望可以經過實驗1的方式順利引入進來。

apache配置：

<VirtualHost *:80>                                                                                                                    
    ServerName api.query.soft.111.cn

    #ScriptAlias / /home/luwenwei/go/base/main
    ScriptAlias /test-cgi /usr/local/apache2/cgi-bin/test-cgi

    ErrorLog logs/error_lww
    CustomLog "|/usr/local/apache2/bin/rotatelogs /usr/local/apache2/logs/lww_access_log.%Y%m%d 86400 480" combinedio
</VirtualHost>

訪問http://api.query.soft.111.cn/test-cgi，指望可以輸出些內容。

實際輸出：

Forbidden

You don't have permission to access /test-cgi on this server.

實際不符合預期。

正確的配置爲：

<VirtualHost *:80>                                                                                                                    
    ServerName api.query.soft.111.cn

    #ScriptAlias / /home/luwenwei/go/base/main
    ScriptAlias /test-cgi /usr/local/apache2/cgi-bin/test-cgi

    <Directory "/usr/local/apache2/cgi-bin/">
        Options -Indexes FollowSymLinks
        AllowOverride None
        Order deny,allow
        Allow from all 
    </Directory>

    ErrorLog logs/error_lww
    CustomLog "|/usr/local/apache2/bin/rotatelogs /usr/local/apache2/logs/lww_access_log.%Y%m%d 86400 480" combinedio
</VirtualHost>

配置好FollowSymLinks後可正常訪問。頁面輸出爲：

CGI/1.0 test script report:

argc is 0. argv is .

SERVER_SOFTWARE = Apache
SERVER_NAME = api.query.soft.111.cn
GATEWAY_INTERFACE = CGI/1.1
SERVER_PROTOCOL = HTTP/1.1
SERVER_PORT = 80
REQUEST_METHOD = GET
HTTP_ACCEPT = text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
PATH_INFO = 
PATH_TRANSLATED = 
SCRIPT_NAME = /test-cgi
QUERY_STRING = 
REMOTE_HOST =
REMOTE_ADDR = 10.18.32.50
REMOTE_USER =
AUTH_TYPE =
CONTENT_TYPE =
CONTENT_LENGTH =
