CentOS7.2上搭建httpd-2.4

CcentOS7.2上搭建httpd-2.4

1.实验需求：

1、建立httpd服务，要求：
(1) 提供两个基于名称的虚拟主机www1, www2；有单独的错误日志和访问日志；
(2) 通过www1的/server-status提供状态信息，且仅允许tom用户访问；
(3) www2不允许192.168.0.0/24网络中任意主机访问；
2、为上面的第2个虚拟主机提供https服务

2.实验环境：

Linux服务器操作系统版本：CentOS release 7.2 (Final) IP：172.16.250.60
WIN7系统客户机：IP：172.16.250.100

3.实验前提：
1）关闭防火墙和SELinux
~]# systemctl stop iptables
~]# setenforce 0

4.实验过程：

1.提供两个基于名称的虚拟主机www1, www2；有单独的错误日志和访问日志

一、安装服务

1)yum安装httpd-2.4
~]# yum install httpd -y
~]# rpm -qa httpd
~]# rpm -ql httpd
/etc/httpd
/var/log/httpd
/var/www/html
~]# rpm -qc httpd
/etc/httpd/conf/httpd.conf
/etc/sysconfig/httpd
/etc/httpd/conf.d/welcome.conf
~]# systemctl restart httpd.service
~]# ss -lnt
LISTEN 0 128 :::80 :::*

二、创建虚拟主机

~]# cat /etc/httpd/conf.d/www1.conf
<VirtualHost 172.16.250.60:80>
ServerName www1.magedu.com
DocumentRoot /data/vhosts/www1
ErrorLog logs/www1-error_log
CustomLog logs/www1-access_log combined
<Directory "/data/vhosts/www1">
Options None
AllowOverride None
Require all granted
</Directory>
</VirtualHost>
~]# cat /etc/httpd/conf.d/www2.conf

<VirtualHost 172.16.250.60:80>
ServerName www2.magedu.com
DocumentRoot /data/vhosts/www2
ErrorLog logs/www2-error_log
CustomLog logs/www2-access_log combiend
<Directory "/data/vhosts/www2">
Options None
AllowOverride None
Require all granted
</Directory>
</VirtualHost>

三、修改配置参数:

注意：基于FQDN的虚拟主机不再需要专门的指令NameVirtualHost

1)备份原有的配置文件
~]# cp -p httpd.conf httpd.conf.bak

2)创建站点目录：
~]# mkdir -pv /data/vhosts/www{1,2}

3)创建访问主页
~]# echo "<h1> www1.magedu.com </h1>" > /data/vhosts/www1/index.html
~]# echo "<h1> www2.magedu.com </h1>" > /data/vhosts/www2/index.html

4)添加hosts域名解析
~]# echo " 172.16.250.60 www1.magedu.com www2.magedu.com " >> /etc/hsots

5)修改配置需要重载
~]# httpd -t
~]# systemctl reload httpd.service

四、PC端上测试内容

1)在wind7上添加域名解析：路径：C:\Windows\System32\drivers\etc\hosts
2)用记事本打开hosts添加并保存：172.16.250.60 www1.magedu.com www2.magedu.com
3)测试都正常访问

2.通过www1的/server-status提供状态信息，且仅允许tom用户访问；

一、修改配置文件：

1)只允许tom用户访问/server-status;
<Location /server-status>
SetHandler server-status
AuthType basic
AuthName "For tom"
AuthUserFile "/etc/httpd/conf/.htpasswd"
Require user tom
</Location>

2)创建虚拟用户tom文件
~]# htpasswd -c -m /etc/httpd/conf/.htpasswd tom

3)检查语法并重载配置文件
~]# httpd -t
~]# systemctl reload httpd.service

二、在PC机浏览器中测试：

1)输入 http://172.16.250.60/server-status 需要用户tom认证才能访问
测试： http://www1.magedu.com/server-status
Apache Server Status for www1.magedu.com (via 172.16.250.60)

3、为上面的第2个虚拟主机提供https服务；

工作目录:/etc/pki/CA/

一、建立私有CA

1)生成私钥
CA]# (umask 077; openssl genrsa -out private/cakey.pem 2048)

2)生成自签证书
CA]# openssl req -new -x509 -key private/cakey.pem -out cacert.pem
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [XX]:CN
State or Province Name (full name) []:Beijing
Locality Name (eg, city) [Default City]:Beijing
Organization Name (eg, company) [Default Company Ltd]:liyang
Organizational Unit Name (eg, section) []:Ops
Common Name (eg, your name or your server's hostname) []:www2.magedu.com
Email Address []:magedu.com@com

3)提供辅助文件
CA]# touch index.txt
CA]# echo 01 > serial 序列号
CA]# tree
.
├── cacert.pem
├── certs
├── crl
├── index.txt
├── newcerts
├── private
│ └── cakey.pem
└── serial

二、节点申请证书

1)生成私钥
~]# mkdir -pv /etc/httpd/ssl
ssl]# (umask 077; openssl genrsa -out httpd.key 1024)

2）生成证书签署请求：
ssl]# openssl req -new -key httpd.key -out httpd.csr
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [XX]:CN
State or Province Name (full name) []:Beijing
Locality Name (eg, city) [Default City]:Beijing
Organization Name (eg, company) [Default Company Ltd]:liyang
Organizational Unit Name (eg, section) []:Ops
Common Name (eg, your name or your server's hostname) []:www2.magedu.com
Email Address []:admin@magedu.com

Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:

3)把请求发给CA
ssl]# cp httpd.csr /tmp/

三、CA签发证书

1)签署证书
~]# openssl ca -in /tmp/httpd.csr -out /etc/pki/CA/certs/httpd.crt
Using configuration from /etc/pki/tls/openssl.cnf
Check that the request matches the signature
Signature ok
Certificate Details:
Serial Number: 1 (0x1)
Validity
Not Before: Jul 14 13:24:47 2016 GMT
Not After : Jul 14 13:24:47 2017 GMT
Subject:
countryName = CN
stateOrProvinceName = Beijing
organizationName = liyang
organizationalUnitName = Ops
commonName = www2.magedu.com
emailAddress = admin@magedu.com
X509v3 extensions:
X509v3 Basic Constraints:
CA:FALSE
Netscape Comment:
OpenSSL Generated Certificate
X509v3 Subject Key Identifier:
88:92:7A:EE:97:0B:51:8C:68:56:4D:E0:51:8E:79:CD:56:D5:DF:05
X509v3 Authority Key Identifier:
keyid:0B:2F:43:5B:2D:B7:5D:F5:11:16:C2:78:0D:15:60:8F:39:9E:CA:70

Certificate is to be certified until Jul 14 13:24:47 2017 GMT (365 days)
Sign the certificate? [y/n]:y

1 out of 1 certificate requests certified, commit? [y/n]y
Write out database with 1 new entries
Data Base Updated

2)把签署好的证书发还给请求者。
~]# cp /etc/pki/CA/certs/httpd.crt /etc/httpd/ssl/

注意：本次私建CA和节点申请证书在同一台机器完成。

四、配置httpd支持使用ssl，及使用的证书

1)yum安装mod_ssl模块
~]# httpd -M | grep ssl
~]# yum install mod_ssl -y
~]# rpm -ql mod_ssl

2）修改配置文件
~]# cat /etc/httpd/conf.d/ssl.conf
<VirtualHost>
DocumentRoot "/data/vhosts/www2"
ServerName www2.magedu.com:443
SSLCertificateFile /etc/httpd/ssl/httpd.crt
SSLCertificateKeyFile /etc/httpd/ssl/httpd.key
<Directory "/data/vhosts/www2">
SSLOptions +StdEnvVars
AllowOverride None
Require all granted
</Directory>
</VirtualHost>

五、测试结果：
1)在PC机浏览器中测试：https://www2.magedu.com 通过443端口访问
2)在PC机浏览器中测试：http://www2.magedu.com 通过80端口访问
