实验需求：

1、Centos 7, apm+xcache, rpm包, PHP module;
a) 一个虚拟主机提供phpMyAdmin，另一个虚拟主机提供Wordpress；
b) 为phpMyAdmim提供https服务；
实验环境：

linux服务器操作系统版本：CentOS Linux release 7.2.1511 (Core) IP：172.16.252.113
WIN7系统客户机：IP：172.16.250.100
实验前提：
   1）关闭防火墙和SELinux
   ~]# service iptables stop
   ~]# setenforce 0
实验过程：

一、安装amp环境

1.yum包安装amp

~]# yum install Httpd php php-Mysql mariadb

   1)检查是否成功安装包
~]# rpm -qa httpd php php-mysql mysql-server

   2)启动服务
~]# systemctl start httpd
~]# systemctl start mariadb

   3)查看服务是否正常启动
~]# ss -nlt
~]# ps aux | grep httpd
~]# ps aux |grep myslq

   4)设置开机自动启动
~]# systemctl enable httpd
~]# systemctl enable mariadb

    5)检查是否设置成开机自启动
~]# systemctl is-enabled httpd
~]# systemctl is-enabled mariadb

2.一个虚拟主机提供phpMyAdmin，另一个虚拟主机提供wordpress；

二、配置虚拟主机

   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
                Require all granted
        </Directory>
</VirtualHost>

   2）vhosts www2

<VirtualHost *: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>

二、部署wordpress环境：

   1)创建站点目录
~]# mkdir /data/vhosts/www1

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

   3)拷贝到站点目录www1中
# cp wordpress /data/vhosts/www1

   4)登录数据库
~]# mysql -uroot -p

   5)为bolg创建数据库名为：wordpress
MariaDB [(none)]> CREATE DATABASE wordpress;

   6)查数据库是否创建成功
MariaDB [(none)]> SHOW DATABASES;
+--------------------+
| Database           |
+--------------------+
| infORMation_schema |
| mysql              |
| performance_schema |
| wordpress          |
+--------------------+
4 rows in set (0.00 sec)

   7)授权用户
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配置文件为wp-config.php
]# cp wp-config-sample.php wp-config.php

   9)修改wp-config.php文件连接数据库
~]# sed -n '22,38p' /data/vhosts/www1/wordpress/wp-config.php

define('DB_NAME', 'wordpress');

define('DB_USER', 'ly');

define('DB_PASSWORD', 'liyang');

define('DB_HOST', '172.16.252.113');

define('DB_CHARSET', 'utf8');

define('DB_COLLATE', '');

三、测试
   1)在服务器端添加域名解析
]# 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是否可以访问
www1]# cat admin.php
<?php
   phpinfo();
?>
   4)httpd-->php--mariadb是否可以访问

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

四、部署phpMyAdmin环境：

   1)创建站点目录
~]# mkdir /data/vhosts/www2

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

   3)拷贝到站点目录www2中
~]# cp -r phpMyAdmin-4.4.14.1-all-languages /data/vhosts/www1

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

5)生成随机数
~]# openssl rand -hex 8
640b56f72820ace8

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

   7)在浏览器中测试，根据提示输入数据库名和密码（主机账号和密码是授权wordpress中用户）
在PC机浏览器中测试：http://www1.magedu.com/phpMyAdmin-4.4.14.1-all-languages/ 通过80端口访问

   8）访问提示：没有扩展，安装 php-mbstring 可以解决
~]# yum install php-mbstring

3.为phpMyAdmim提供https服务

工作目录:/etc/pki/CA/

一、建立私有CA

   1)生成私钥

[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)生成自签证书
[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)提供辅助文件

[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、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) []: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 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)配置虚拟主机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、测试结果：

   1)在PC机浏览器中测试：https://www1.magedu.com/phpMyAdmin-4.4.14.1-all-languages/ 通过443端口访问

4.压力测试：
