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 mariadb2. 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/*.conf; //包含自定义虚拟主机路径fastcgi_cache_path /var/cache/Nginx/fastcgi levels=1:1 keys_zone=fcgicache:10m max_size=1g; //定义缓存路径,级别,缓存空间名称,磁盘缓存最大缓存数 3）创建缓存目录# mkdir -pv /var/cache/Nginx/fastcgi 4）配置虚拟主机/conf.d/vhosts.confserver { listen 80; server_name www.yang.com; gzip on; gzip_disable chrome; gzip_types text/plain text/css text/xml application/xml application/json application/x-javascript;location / { root /web/host1/wordpress; index index.PHP index.html index.htm; } location ~ \.PHP$ { root /web/host1/wordpress; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.PHP; fastcgi_param SCRIPT_FILENAME /web/host1/wordpress/$fastcgi_script_name; fastcgi_cache fcgicache; fastcgi_cache_key $request_uri; fastcgi_cache_valid 200 10m; fastcgi_cache_valid 301 302 2m; fastcgi_cache_valid 404m; include fastcgi.conf; }}server { listen 80; server_name web.yang.com; root /web/host2/PHPmyadmin; location / { index index.PHP index.html index.html;}location ~ \.PHP$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.PHP; fastcgi_param SCRIPT_FILENAME /web/host2/PHPmyadmin/$fastcgi_script_name; fastcgi_cache fcgicache; fastcgi_cache_key $request_uri; fastcgi_cache_valid 200 10m; fastcgi_cache_valid 301 302 2m; fastcgi_cache_valid 404 2m; include fastcgi.conf; }}server { ssl on; listen 443 ssl; server_name web.yang.com; root /web/host2/PHPmyadmin; ssl_certificate /etc/Nginx/ssl/Nginx.crt; ssl_certificate_key /etc/Nginx/ssl/Nginx.key; ssl_session_cache shared:SSL:5m; ssl_session_timeout 10m; ssl_ciphers HIGH:!aNULL:!MD5; ssl_prefer_server_ciphers on; location / { index index.PHP index.html index.htm; } location ~ \.PHP$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.PHP; fastcgi_param SCRIPT_FILENAME /web/host2/PHPmyadmin/$fastcgi_script_name; fastcgi_cache fcgicache; fastcgi_cache_key $request_uri; fastcgi_cache_valid 200 10m; fastcgi_cache_valid 301 302 2m; fastcgi_cache_valid 404 3m; include fastcgi.conf; }}二、部署wordpress环境： 1)创建站点目录# mkdir /web/host1/ -pv 2)解压wordpress包# unzip wordpress-4.3.1-zh_CN.zip 3)拷贝到站点目录www1中# cp -R wordpress /web/host1/ 4)修改网站属主和属组# chown -R Nginx.Nginx /web/host1/wordpress 5)修改PHP-fpm.conf下的www.confuser = Nginx group = Nginx 6)登录数据库# MysqL -uroot -p 7)为bolg创建数据库名为：wordpressMariaDB [(none)]> CREATE DATABASE wordpress; 8)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) 9)授权用户MariaDB [(none)]> GRANT ALL ON wordpress.* TO liyang@'localhost' IDENTIFIED BY 'liyang';Query OK,0 rows affected (0.03 sec)MariaDB [(none)]> GRANT ALL ON wordpress.* TO liyang@'172.16.%.%' IDENTIFIED BY 'liyang';Query OK,0 rows affected (0.00 sec) 10)改名wordpress配置文件为wp-config.php# cp wp-config-sample.PHP wp-config.php 11)修改wp-config.php文件连接数据库# sed -n '22,38p' /web/host1/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','liyang');/** MysqL数据库密码 */define('DB_PASSWORD','liyang');/** MysqL主机 */define('DB_HOST','localhost');/** 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 "172.16.66.60 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 <?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 -pMariaDB [(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.pemYou are about to be asked to enter information that will be incorporatedinto 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 blankFor 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) []:BeijingLocality Name (eg,city) [Default City]:BeijingOrganization Name (eg,company) [Default Company Ltd]:liyangOrganizational Unit Name (eg,section) []:Ops Common Name (eg,your name or your server's hostname) []:web.yang.comEmail 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/sslssl]# (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.csrYou are about to be asked to enter information that will be incorporatedinto 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 blankFor some fields there will be a default value,the field will be left blank.-----Country Name (2 letter code) [XX]:CNState or Province Name (full name) []:BeijingLocality Name (eg,section) []:OpsCommon Name (eg,your name or your server's hostname) []:web.yang.comEmail Address []:admin@yang.comPlease enter the following 'extra' attributesto be sent with your certificate requestA 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.crtUsing configuration from /etc/pki/tls/openssl.cnfCheck that the request matches the signatureSignature okCertificate 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 Netscape Comment: OpenSSL Generated Certificate X509v3 Subject Key Identifier: F5:73:F0:F1:7F:B6:B6:5D:41:F1:ED:7A:69:FE:6F:8E:A6:59:41:42 X509v3 Authority Key Identifier: keyid:91:41:DA:D3:44:05:36:98:14:A7:81:D6:64:AC:D5:8E:EB:6E:D3:97Certificate is to be certified until Jul 29 11:11:37 2017 GMT (365 days)Sign the certificate?
