httpd服务相关实验

实验环境：

CentOS6.8

1、连接测试：

　　在/etc/httpd/conf/httpd.conf

　　telnet 172.16.252.242 80

　　GET /index.html HTTP/1.1

　　Host: 172.16.252.242

# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#
KeepAlive Off　　#长连接状态是关闭的

[root@www ~18:47:34]#telnet 172.16.252.242 80
Trying 172.16.252.242...
Connected to 172.16.252.242.
Escape character is '^]'.
GET /index.html HTTP/1.1
Host: 172.16.252.242
Connection closed by foreign host.

修改KeepAlive:/etc/httpd/conf/httpd.conf

KeepAlive On　　#开启
#
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
#
MaxKeepAliveRequests 100

#
# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.
#
KeepAliveTimeout 15　　#等待时间

[root@conf localhost6]#service httpd restart　　#修改配置文件，必须重新启动服务
Stopping httpd: [ OK ]
Starting httpd: httpd: apr_sockaddr_info_get() failed for localhost6.8.localdomain
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
[ OK ]

#此时一次请求结束后，不会退出，而是等待下次请求，超过等待时间，则退出

 2、http的访问控制——认证

　　1）在主配置文件定义安全域

# DocumentRoot: The directory out of which you will serve your
# documents. By default, all requests are taken from this directory, but
# symbolic links and aliases may be used to point to other locations.
#
DocumentRoot "/www/host1/"
#此目录下有个目录admin下的文件需要用户进行http的认证访问

[root@admin localhost6]#pwd
/www/host1/admin
[root@admin localhost6]#cat admin.html 　　#此文件需要认证才能访问
<h1> warn:admin area</h1>

[root@admin localhost6]#vi /etc/httpd/conf/httpd.conf  #配置的文件

<Directory "/www/host1/admin/">　　 #认证后才能显示的目录
        Options None　　　　　　　　　#INDEXES等设置不生效
        AllowOverride None　　　　　 #覆盖不生效
        Authtype Basic　　　　　　　　#认证方式：basic和digest
        Authname "input your username and passwd" #认证提示页显示
        Authuserfile "/etc/httpd/conf/.htpasswd"　　#认证校验的密码文件
        require user tom　　　　　　　　　　　　　　#需要认证的用户
#       require valid-user　　　　　　　　　　　　　#密码文件中的用户都需要认证
</Directory>

2）创建账号和密码校验的加密文件

[root@admin localhost6]#htpasswd -c -m /etc/httpd/conf/.htpasswd tom
New password: 
Re-type new password: 
Adding password for user tom
[root@admin localhost6]#htpasswd  -m /etc/httpd/conf/.htpasswd jey
New password: 
Re-type new password: 
Adding password for user jey
#-c：自动创建指定的密码文件，仅首次创建文件时使用
#-m:用md5加密方式进行加密
#tom；需要认证的用户

 

#重启服务：
[root@admin localhost6]#service httpd reload
Reloading httpd: 

 

输入用户名和密码进行验证。
