如何在Ubuntu上搭建apache服务器

1.安装apache2服务器

注意：如果以及安装可以这一步可以忽略

sudo apt install apache2； 
sudo apt install apache2； 
sudo apt install apache2； 

2、查看是否安装成功

在浏览器输入Ubuntu的IP地址，出现以下情况视为成功

3.配置apache支持cgi程序

因为apache中的cgi功能需要我们自己去开启，因此我们需要
进入/etc/apache2/mods-enabled目录下
把上一级目录下mods-available（存放apache所支持的功能）内的cgi配置文件拷贝到当前目录下（也可以创建软连接)进行开启；如下（二选一）
3.1.1、复制配置文件

gec@ubuntu:/etc/apache2/mods-enabled$ <span class="token function">sudo</span> <span class="token function">cp</span> <span class="token punctuation">..</span>/mods-available/cgid.conf cgid.conf gec@ubuntu:/etc/apache2/mods-enabled$ <span class="token function">sudo</span> <span class="token function">cp</span> <span class="token punctuation">..</span>/mods-available/cgid.load cgid.load gec@ubuntu:/etc/apache2/mods-enabled$ <span class="token function">sudo</span> <span class="token function">cp</span> <span class="token punctuation">..</span>/mods-available/cgi.load cgi.load 
gec@ubuntu:/etc/apache2/mods-enabled$ <span class="token function">sudo</span> <span class="token function">cp</span> <span class="token punctuation">..</span>/mods-available/cgid.conf cgid.conf gec@ubuntu:/etc/apache2/mods-enabled$ <span class="token function">sudo</span> <span class="token function">cp</span> <span class="token punctuation">..</span>/mods-available/cgid.load cgid.load gec@ubuntu:/etc/apache2/mods-enabled$ <span class="token function">sudo</span> <span class="token function">cp</span> <span class="token punctuation">..</span>/mods-available/cgi.load cgi.load 
gec@ubuntu:/etc/apache2/mods-enabled$ sudo cp ../mods-available/cgid.conf cgid.conf gec@ubuntu:/etc/apache2/mods-enabled$ sudo cp ../mods-available/cgid.load cgid.load gec@ubuntu:/etc/apache2/mods-enabled$ sudo cp ../mods-available/cgi.load cgi.load 

3.1.2、创建软连接
如果已经复制了配置文件则无需再创建软链接！！

gec@ubuntu:/etc/apache2/mods-enabled$ <span class="token function">sudo</span> <span class="token function">ln</span> -s <span class="token punctuation">..</span>/mods-available/cgid.conf cgid.conf gec@ubuntu:/etc/apache2/mods-enabled$ <span class="token function">sudo</span> <span class="token function">ln</span> -s <span class="token punctuation">..</span>/mods-available/cgid.load cgid.load gec@ubuntu:/etc/apache2/mods-enabled$ <span class="token function">sudo</span> <span class="token function">ln</span> -s <span class="token punctuation">..</span>/mods-available/cgi.load cgi.load 
gec@ubuntu:/etc/apache2/mods-enabled$ <span class="token function">sudo</span> <span class="token function">ln</span> -s <span class="token punctuation">..</span>/mods-available/cgid.conf cgid.conf gec@ubuntu:/etc/apache2/mods-enabled$ <span class="token function">sudo</span> <span class="token function">ln</span> -s <span class="token punctuation">..</span>/mods-available/cgid.load cgid.load gec@ubuntu:/etc/apache2/mods-enabled$ <span class="token function">sudo</span> <span class="token function">ln</span> -s <span class="token punctuation">..</span>/mods-available/cgi.load cgi.load 
gec@ubuntu:/etc/apache2/mods-enabled$ sudo ln -s ../mods-available/cgid.conf cgid.conf gec@ubuntu:/etc/apache2/mods-enabled$ sudo ln -s ../mods-available/cgid.load cgid.load gec@ubuntu:/etc/apache2/mods-enabled$ sudo ln -s ../mods-available/cgi.load cgi.load 

3.2、然后重启apache服务器

 <span class="token function">sudo</span> apachectl restart 
 <span class="token function">sudo</span> apachectl restart 
 sudo apachectl restart 

重启会出现以下错误：

然后打开/etc/apache2/apache2.conf在文件最前面添加添加ServerName 127.0.0.1再重新启动

sudo vi <span class="token operator">/</span>etc<span class="token operator">/</span>apache2<span class="token operator">/</span>apache2<span class="token punctuation">.</span>conf 
sudo vi <span class="token operator">/</span>etc<span class="token operator">/</span>apache2<span class="token operator">/</span>apache2<span class="token punctuation">.</span>conf 
sudo vi /etc/apache2/apache2.conf 

然后去到/etc/apache2/conf-enabled目录下打开serve-cgi-bin.conf文件，里面可以看到我们cgi程序放置的默认目录，若想把cgi程序放在其他地方则可以修改该路径

vim serve<span class="token operator">-</span>cgi<span class="token operator">-</span>bin<span class="token punctuation">.</span>conf 
vim serve<span class="token operator">-</span>cgi<span class="token operator">-</span>bin<span class="token punctuation">.</span>conf 
vim serve-cgi-bin.conf 

4、测试

进入/usr/lib/cgi-bin/目录下编写一个c/c++程序

<span class="token macro property">#<span class="token directive keyword">include</span> <span class="token string"><stdio.h></span></span> <span class="token keyword">int</span> <span class="token function">main</span><span class="token punctuation">(</span><span class="token keyword">void</span><span class="token punctuation">)</span> <span class="token punctuation">{<!-- --></span> <span class="token function">printf</span><span class="token punctuation">(</span><span class="token string">"Content-type:text/html;charset=utf-8\n\n"</span><span class="token punctuation">)</span><span class="token punctuation">;</span> <span class="token function">printf</span><span class="token punctuation">(</span><span class="token string">"hello world\n\n"</span><span class="token punctuation">)</span><span class="token punctuation">;</span> <span class="token function">printf</span><span class="token punctuation">(</span><span class="token string">"hello world\n\n"</span><span class="token punctuation">)</span><span class="token punctuation">;</span> <span class="token function">printf</span><span class="token punctuation">(</span><span class="token string">"hello world\n\n"</span><span class="token punctuation">)</span><span class="token punctuation">;</span> <span class="token function">printf</span><span class="token punctuation">(</span><span class="token string">"hello world\n\n"</span><span class="token punctuation">)</span><span class="token punctuation">;</span> <span class="token function">printf</span><span class="token punctuation">(</span><span class="token string">"hello world\n\n"</span><span class="token punctuation">)</span><span class="token punctuation">;</span> <span class="token function">printf</span><span class="token punctuation">(</span><span class="token string">"hello world\n\n"</span><span class="token punctuation">)</span><span class="token punctuation">;</span> <span class="token function">printf</span><span class="token punctuation">(</span><span class="token string">"hello world\n\n"</span><span class="token punctuation">)</span><span class="token punctuation">;</span> <span class="token function">printf</span><span class="token punctuation">(</span><span class="token string">"hello world\n\n"</span><span class="token punctuation">)</span><span class="token punctuation">;</span> <span class="token keyword">return</span> <span class="token number">0</span><span class="token punctuation">;</span> <span class="token punctuation">}</span>

#include <stdio.h> int main(void) { printf("Content-type:text/html;charset=utf-8\n\n"); printf("hello world\n\n"); printf("hello world\n\n"); printf("hello world\n\n"); printf("hello world\n\n"); printf("hello world\n\n"); printf("hello world\n\n"); printf("hello world\n\n"); printf("hello world\n\n"); return 0; } 

然后在浏览器中进行访问（注意：需要指定访问的是哪个文件）

运行结果：
