2.一個虛擬主機(jī)提供phpMyAdmin，另一個虛擬主機(jī)提供wordpress；

二、配置虛擬主機(jī)
                
    1）vhosts www1
    
<VirtualHost *:80>
        ServerName www1.magedu.com
        DocumentRoot /data/vhosts/www1
        ErrorLog logs/www1-error_log
        CustomLog logs/www1-access_log combiend
        <Directory "/data/vhosts/www1">
                Options None
                AllowOverride   None

                Options None
                AllowOverride None
                Require all granted
        </Directory>
</VirtualHost>
                        
二、部署wordpress環(huán)境：

    1)創(chuàng)建站點(diǎn)目錄
~]# mkdir /data/vhosts/www1

    2)解壓wordpress包
tools]# unzip wordpress-4.3.1-zh_CN.zip

    3)拷貝到站點(diǎn)目錄www1中
# cp wordpress /data/vhosts/www1

    4)登錄數(shù)據(jù)庫
~]# mysql -uroot -p

    5)為bolg創(chuàng)建數(shù)據(jù)庫名為：wordpress
MariaDB [(none)]> CREATE DATABASE wordpress;

    6)查數(shù)據(jù)庫是否創(chuàng)建成功
MariaDB [(none)]> SHOW DATABASES;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| wordpress          |
+--------------------+
4 rows in set (0.00 sec)

    7)授權(quán)用戶
MariaDB [(none)]> GRANT ALL ON wordpress.* TO ly@'localhost' IDENTIFIED BY 'liyang';
Query OK, 0 rows affected (0.03 sec)

MariaDB [(none)]> GRANT ALL ON wordpress.* TO ly@'127.0.0.1' IDENTIFIED BY 'liyang';
Query OK, 0 rows affected (0.01 sec)

MariaDB [(none)]> GRANT ALL ON wordpress.* TO ly@'172.16.%.%' IDENTIFIED BY 'liyang';
Query OK, 0 rows affected (0.00 sec)

    8)改名wordpress配置文件為wp-config.php
]# cp wp-config-sample.php wp-config.php
    
    9)修改wp-config.php文件連接數(shù)據(jù)庫
 ~]# sed -n '22,38p' /data/vhosts/www1/wordpress/wp-config.php
/** WordPress數(shù)據(jù)庫的名稱 */
define('DB_NAME', 'wordpress');
/** MySQL數(shù)據(jù)庫用戶名 */
define('DB_USER', 'ly');
/** MySQL數(shù)據(jù)庫密碼 */
define('DB_PASSWORD', 'liyang');
/** MySQL主機(jī) */
define('DB_HOST', '172.16.252.113');
/** 創(chuàng)建數(shù)據(jù)表時(shí)默認(rèn)的文字編碼 */
define('DB_CHARSET', 'utf8');
/** 數(shù)據(jù)庫整理類型。如不確定請勿更改 */
define('DB_COLLATE', '');
    
三、測試
    1)在服務(wù)器端添加域名解析
]# echo "172.16.252.113 www1.magedu.com" >> /etc/hosts

    2)在PC中的hosts文件中添加
172.16.252.113 www1.magedu.com

    3)httpd-->php是否可以訪問
www1]# cat admin.php
<?php
    phpinfo();
?>
    4)httpd-->php--mariadb是否可以訪問

<?php
                        $conn = mysql_connect('172.16.100.71','testuser','testpass');
                        if($conn)
                            echo "OK";
                        else
                            echo "Failure";

?>               
   
    5)在瀏覽器中，根據(jù)提示安裝http://www2.magedu.com/wordpress/index.php

    6）查看數(shù)據(jù)庫是否生成數(shù)據(jù)
~]# mysql -uly -p
MariaDB [(none)]> show databases;

MariaDB [(none)]> use wordpress;

MariaDB [wordpress]> show tables;
+-----------------------+
| Tables_in_wordpress   |
+-----------------------+
| wp_commentmeta        |
| wp_comments           |
| wp_links              |
| wp_options            |
| wp_postmeta           |
| wp_posts              |
| wp_term_relationships |
| wp_term_taxonomy      |
| wp_terms              |
| wp_usermeta           |
| wp_users              |
+-----------------------+
11 rows in set (0.00 sec)
  

四、部署phpMyAdmin環(huán)境：

    1)創(chuàng)建站點(diǎn)目錄
~]# mkdir /data/vhosts/www2

    2)解壓phpMyAdmin包
tools]# unzip phpMyAdmin-4.4.14.1-all-languages.zip

    3)拷貝到站點(diǎn)目錄www2中
~]# cp -r phpMyAdmin-4.4.14.1-all-languages /data/vhosts/www1

    4)配置phpMyAdmin軟件
www1]# ln -sv phpMyAdmin-4.4.14.1-all-languages/ phpMyAdmin
~]# cp config.sample.inc.php config.inc.php

    5)生成隨機(jī)數(shù)
~]# openssl rand -hex 8  
640b56f72820ace8

    6修改配置文件config.inc.php
]# vim config.inc.php
$cfg['blowfish_secret'] = '640b56f72820ace8'

    7)在瀏覽器中測試，根據(jù)提示輸入數(shù)據(jù)庫名和密碼（主機(jī)賬號和密碼是授權(quán)wordpress中用戶）
在PC機(jī)瀏覽器中測試：http://www1.magedu.com/phpMyAdmin-4.4.14.1-all-languages/ 通過80端口訪問

    8）訪問提示：沒有擴(kuò)展，安裝 php-mbstring 可以解決
~]# yum install php-mbstring

3.為phpMyAdmim提供https服務(wù)

工作目錄:/etc/pki/CA/

一、建立私有CA

    1)生成私鑰

[root@localhost CA]# (umask 077; openssl genrsa -out private/cakey.pem 2048)
Generating RSA private key, 2048 bit long modulus
.....+++
...........+++
e is 65537 (0x10001)

    2)生成自簽證書
[root@localhost 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) []:0ps
Common Name (eg, your name or your server's hostname) []:www2.magedu.com
Email Address []:admin@magedu.com

    3)提供輔助文件

[root@localhost CA]# touch index.txt
[root@localhost CA]# echo 01 > serial
[root@localhost CA]# tree
.
├── cacert.pem
├── certs
├── crl
├── index.txt
├── index.txt.attr
├── index.txt.old
├── newcerts
├── private
│   └── cakey.pem
├── serial
└── serial.old


二、節(jié)點(diǎn)申請證書
    
    1)生成私鑰
~]# mkdir -pv /etc/httpd/ssl
ssl]# (umask 077; openssl genrsa -out httpd.key 1024)

    2）生成證書簽署請求：
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) []:0ps
Common Name (eg, your name or your server's hostname) []:www1.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 []:


ssl]# cp httpd.csr /tmp/


三、CA簽發(fā)證書

    1)簽署證書
~]# 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 16 07:41:43 2016 GMT
            Not After : Jul 16 07:41:43 2017 GMT
        Subject:
            countryName               = CN
            stateOrProvinceName       = Beijing
            organizationName          = liyang
            organizationalUnitName    = 0ps
            commonName                = www2.magedu.com
            emailAddress              = admin@magedu.com
        X509v3 extensions:
            X509v3 Basic Constraints:
                CA:FALSE
            Netscape Comment:
                OpenSSL Generated Certificate
            X509v3 Subject Key Identifier:
                70:95:31:1F:E3:15:D0:EE:D1:8F:2E:DA:8C:64:95:F6:EA:80:8F:2D
            X509v3 Authority Key Identifier:
                keyid:79:B8:17:4E:7D:74:2D:CD:16:63:20:1D:D1:9F:AA:D1:5F:49:09:CA

Certificate is to be certified until Jul 16 07:41:43 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)把簽署好的證書發(fā)還給請求者。
~]# cp /etc/pki/CA/certs/httpd.crt /etc/httpd/ssl/

注意：本次私建CA和節(jié)點(diǎn)申請證書在同一臺機(jī)器完成。

四、配置httpd支持使用ssl，及使用的證書

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

    2)配置虛擬主機(jī)ssh.conf
 ~]# vim /etc/httpd/conf.d/ss.conf
<VirtualHost _default_:443>    
    DocumentRoot "/data/vhosts/www2"
    ServerName www1.magedu.com:443
    SSLCertificateFile /etc/httpd/ssl/httpd.crt
    SSLCertificateKeyFile /etc/httpd/ssl/httpd.key
<Directory "/data/vhosts/www1">
    SSLOptions +StdEnvVars
    AllowOverride None
    Require all granted
</Directory>

</VirtualHost>
    
五、測試結(jié)果：

    1)在PC機(jī)瀏覽器中測試：https://www1.magedu.com/phpMyAdmin-4.4.14.1-all-languages/ 通過443端口訪問
