CentOS 7, apm+xcache, rpm包, php module

  1. 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；

  2. 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

  3. 实验前提：
        1）关闭防火墙和SELinux    
        ~]# service iptables stop
        ~]# setenforce 0
  4. 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 [email protected]‘localhost‘ IDENTIFIED BY ‘liyang‘;
Query OK, 0 rows affected (0.03 sec)

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

MariaDB [(none)]> GRANT ALL ON wordpress.* TO [email protected]‘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
/** WordPress数据库的名称 */
define(‘DB_NAME‘, ‘wordpress‘);
/** MySQL数据库用户名 */
define(‘DB_USER‘, ‘ly‘);
/** MySQL数据库密码 */
define(‘DB_PASSWORD‘, ‘liyang‘);
/** MySQL主机 */
define(‘DB_HOST‘, ‘172.16.252.113‘);
/** 创建数据表时默认的文字编码 */
define(‘DB_CHARSET‘, ‘utf8‘);
/** 数据库整理类型。如不确定请勿更改 */
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";

?>               
   
    5)在浏览器中，根据提示安装http://www2.magedu.com/wordpress/index.php

6）查看数据库是否生成数据
~]# 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

[[email protected] 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
[[email protected] 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 []:[email protected]

3)提供辅助文件

[[email protected] CA]# touch index.txt
[[email protected] CA]# echo 01 > serial
[[email protected] 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 []:[email protected]

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              = [email protected]
        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：
    
一、正常测试

1)测试并发
