一） 限制客户端访问

curl -i http://192.168.126.150/awstats/awstats.pl?config=ftp150.qm5678.com

curl -i http://192.168.126.150/awstats/awstats.pl?config=ftp150.qm5678.com  | head 

httpd.conf  ## perl 

    520 Alias /awstatsclasses "/usr/local/awstats/wwwroot/classes/"
    521 Alias /awstatscss "/usr/local/awstats/wwwroot/css/"
    522 Alias /awstatsicons "/usr/local/awstats/wwwroot/icon/"
    523 ScriptAlias /awstats/ "/usr/local/awstats/wwwroot/cgi-bin/"
    524
    525 #
    526 # This is to permit URL access to scripts/files in AWStats directory.
    527 #
    528 <Directory "/usr/local/awstats/wwwroot">
    529     Options None
    530     AllowOverride None
    531     Require all granted
    532 </Directory>

 Options None
 AllowOverride None
 <RequireAll>
 Require all granted
 Require not ip 192.168.126.151
 </RequireAll>
</Directory>


二） htpasswd 命令，创建需要用户密码访问

htpasswd -c /usr/local/httpd/conf/.awspwd zhangsan    # -c 创建    234567
htpasswd  /usr/local/httpd/conf/.awspwd lisi           # 765432



<Requireall>
 AuthName "sui bian xie mei guan xi"
 AuthType Basic
 AuthUserFile /usr/local/httpd/conf/.awspwd
 Require valid-user
</Requireall>

##  man  curl  # 搜索 -u    -u, --user <user:password>

curl -i  http://192.168.126.150/awstats/awstats.pl?config=ftp150.qm5678.com
curl -i -u zhangsan:234567 http://192.168.126.150/awstats/awstats.pl?config=ftp150.qm5678.com  | head 
curl -i -u lisi:765432     http://192.168.126.150/awstats/awstats.pl?config=ftp150.qm5678.com  | head 
#type basic,  jwt 

curl  -i    http://ftp150.qm5678.com/desk.jpg   ##默认打印在屏幕上。
curl  -O  http://ftp150.qm5678.com/desk.jpg 
curl  -LO  http://ftp150.qm5678.com/desk.jpg   ## -L following 

curl html api / wget -c 断点续传 / aria2c 增加下载线程数 

http status code  # http状态码
200(ok)  304（not modified since last time）  301  302，  404, 401(unauthorized用户密码不对)， 403(权限不够)
500,  502(bad gateway), 503   # nginx = apache



## 自定义错误页面
httpd.conf 
 437 #ErrorDocument 404 /missing.html




##  模拟301  302 页面跳转
