使用CentOS 7和CentOS 6实现以下任务
-
配置四个基于名称的虚拟主机；
discuzX
wordpress
drupal
1.在conf.d下新建并编辑虚拟主机配置文件]# cd /etc/httpd/conf.d/]# vim vhost.conf
centos6配置[root@ _93_ conf.d]# cat /etc/httpd/conf.d/vhost.conf NameVirtualHost *:80 <VirtualHost *:80> ServerName www.discuzx.com DocumentRoot "/vhost/discuzx/" </VirtualHost> <VirtualHost *:80> ServerName www.wordpress.com DocumentRoot "/vhost/wordpress/" </VirtualHost> <VirtualHost *:80> ServerName www.drupal.com DocumentRoot "/vhost/drupal/" </VirtualHost>
centos7配置
<VirtualHost *:80> ServerName www.discuzx.com DocumentRoot "/vhost/discuzx/" <Directory "/vhost/discuzx/"> Options None Allowoverride None require all granted </Directory> </VirtualHost> <VirtualHost *:80> ServerName www.wordpress.com DocumentRoot "/vhost/wordpress/" <Directory "/vhost/wordpress/"> Options None Allowoverride None require all granted </Directory> </VirtualHost> <VirtualHost *:80> ServerName www.drupal.com DocumentRoot "/vhost/drupal/" <Directory "/vhost/drupal/"> Options None Allowoverride None require all granted </Directory> </VirtualHost>
2.创建本地文件系统资源目录
]# mkdir -pv /vhost/{discuzx,wordpress,drupal}/
mkdir: created directory ‘/vhost’
mkdir: created directory ‘/vhost/discuzx/’
mkdir: created directory ‘/vhost/wordpress/’
mkdir: created directory ‘/vhost/drupal/’
3.创建首页]# cd /vhost/]# for i in `ls`; do echo "The page is $i" > /vhost/${i}/index.html ;done
]# tree . ├── discuzx │ └── index.html ├── drupal │ └── index.html └── wordpress └── index.html
4.检查语法
]# httpd -t Syntax OK
5.reload httpd服务]# service httpd reload或]# systemctl reload httpd
6.测试
(d) phpMyAdmin，此虚拟主机仅支持https协议；
1.CA自签（192.168.33.67为https服务器，192.168.33.77主机为CA机构）生成私钥
]# (umask 077;openssl genrsa -out /etc/pki/CA/private/cakey.pem 4096)
生成自签证书
[root@ _21_ ~]# openssl req -x509 -new -key /etc/pki/CA/private/cakey.pem -out /etc/pki/CA/cacert.pem -days 365 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]:Magedu Organizational Unit Name (eg, section) []:Opt Common Name (eg, your name or your server's hostname) []:www.gen.com Email Address []:gen@qq.com
为CA提供所需的文件及目录
[root@ _22_ ~]# mkdir -pv /etc/pki/CA/{certs,crl,newcerts}
[root@ _23_ ~]# touch /etc/pki/CA/{serial,index.txt}
[root@ _24_ ~]# echo 01 > /etc/pki/CA/serial
https服务器生成私钥
]# mkdir /etc/httpd/ssl/ ]# cd /etc/httpd/ssl [root@ _104_ /etc/httpd/ssl]# openssl req -new -key httpd.key -out httpd.csr -days 365 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]:Magedu Organizational Unit Name (eg, section) []:Opt Common Name (eg, your name or your server's hostname) []:www.phpmyadmin.com Email Address []:php@qq.com Please enter the following 'extra' attributes to be sent with your certificate request A challenge password []: An optional company name []: 之后发送给CA主机签署
CA主机签署证书
[root@ _38_ tmp]# openssl ca -in httpd.csr -out /root/httpd.crt -days 365 两次回答yes
把证书发送给提供https服务的主机
配置httpd支持使用ssl，及使用的证书
]# yum -y install mod_ssl ]# vim /etc/httpd/conf.d/ssl.conf <VirtualHost _default_:443> ServerName www.phpmyadmin.com DocumentRoot "/vhost/phpmyadmin/" <Directory "/vhost/phpmyadmin/"> Options None AllowOverride None require all granted </Directory> SSLCertificateFile /etc/httpd/ssl/httpd.crt SSLCertificateKeyFile /etc/httpd/ssl/httpd.key
物理机IE浏览器访问
导入CA证书到浏览器，然后访问

对phpMyAdmin首页做压力测试
