1. 安裝apache
yum install -y httpd
2. 配置apache
修改apache配置檔案/etc/httpd/conf/httpd.conf將下面一行的註釋去掉，如果沒有則新增:
LoadModule cgid_module modules/mod_cgid.so
cgi指令碼檔案的預設路徑為/var/www/cgi-bin/
修改如下幾處內容:
<Directory />
AllowOverride none
Require all denied
</Directory>
為：
<Directory "/var/www/cgi-bin">
AllowOverride None
Options +ExecCGI
Order allow,deny
Allow from all
</Directory>
去掉註釋並新增.py
AddHandler cgi-script .cgi .py
3.重啟apache
第一、啟動、終止、重啟
systemctl start httpd.service #啟動
systemctl stop httpd.service #停止
systemctl restart httpd.service #重啟
第二、設定開機啟動/關閉
systemctl enable httpd.service #開機啟動
systemctl disable httpd.service #開機不啟動
4.檢查httpd狀態
systemctl status httpd.service
● httpd.service - The Apache HTTP Server
Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled)

man:apachectl(8)

5編寫程式碼
#!/usr/bin/python
#coding=utf-8
print “Content-type:text/html”
print #空行，告訴伺服器結束頭部
print ‘<html>’
print ‘<head>’
print ‘<meta charset=“utf-8”>’
print ‘<title>Hello Word - 我的第一個CGI程式！</title>’
print ‘</head>’
print ‘<body>’
print ‘<h2>嘿！ 你最帥了 ~</h2>’
print ‘</body>’
print ‘</html>’
6前臺測試
