实验需求：
1、CentOS 7, npm rpm包, php-fpm;
a) 一个虚拟主机提供wordpress，另一个虚拟主机提供phpmysamin；
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nmp
# yum install nginx php-fpm php-mysql mariadb-server -y
1)检查是否成功安装包
# rpm -qa nginx php-fpm php-mysql mariadb-server
2)启动服务
# nginx
# systemctl start mariadb
3)查看服务是否正常启动
# ss -nlt
# ps aux | grep nginx
# ps aux | grep myslq
# ps aux | grep php-fpm
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. 配置虚拟主机
1）创建虚拟主机目录和配置文件/conf.d/vhosts.conf
# mkdir -pv /etc/nginx/conf.d/vhosts.conf
2）在nginx.conf中的http段添加如下内容
include conf.d
define('DB_NAME', 'wordpress');
define('DB_USER', 'liyang');
define('DB_PASSWORD', 'liyang');
define('DB_HOST', 'localhost');
define('DB_CHARSET', 'utf8');
define('DB_COLLATE', '');
三、测试
1)在服务器端添加域名解析
# echo "172.16.66.60 www.yang.com" >> /etc/hosts
2)在PC中的hosts文件中添加
172.16.66.60 www.yang.com
3)httpd-->php是否可以访问
# cat admin.php
phpinfo();
?>
4)httpd-->php--mariadb是否可以访问
5)在浏览器中，根据提示安装http://www.yang.com/index.php
6）查看数据库是否生成数据
~]# mysql -uliyang -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 /web/host2
2)解压phpMyAdmin包
# 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 /web/host2/
4)创建软连接phpMyAdmin
# ln -sv phpMyAdmin-4.4.14.1-all-languages/ phpmyadmin
5)修改网站属主和属组
# chown -R nginx.nginx /web/host2/phpmyadmin
6)修改配置文件
# cp config.sample.inc.php config.inc.php
7)生成随机数
~]# openssl rand -hex 8
640b56f72820ace8
8)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://web.yang.com/index.php 通过80端口访问
8）phpmyadmin错误：The mbstring extension is missing. Please check your PHP configuration.
解决方法：
# yum install php-mbstring -y
9)phpmyadmin错误:Error during session start; please check your PHP and/or webserver log file and configure your PHP i
解决方法:
# mkdir -pv /var/lib/php/session
# chown -R nginx.nginx /var/lib/php/session/
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@www 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@www 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) []:web.yang.com
Email Address []:admin@yang.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 nginx.key 1024)
2）生成证书签署请求：
[root@www ssl]# openssl req -new -key nginx.key -out nginx.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) []:web.yang.com
Email Address []:admin@yang.com
Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:
ssl]# cp nginx.csr /tmp/
三、CA签发证书
1)签署证书
[root@www ~]# openssl ca -in /tmp/nginx.csr -out /etc/pki/CA/certs/nginx.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 29 11:11:37 2016 GMT
Not After : Jul 29 11:11:37 2017 GMT
Subject:
countryName = CN
stateOrProvinceName = Beijing
organizationName = liyang
organizationalUnitName = Ops
commonName = web.yang.com
emailAddress = admin@yang.com
X509v3 extensions:
X509v3 Basic Constraints:
CA:FALSE

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/nginx.crt /etc/nginx/ssl/
注意：本次私建CA和节点申请证书在同一台机器完成。
