THREE DAY
案例1：部署LNMP环境
案例2：构建LNMP平台
案例3：地址重写
LNMP（linux nginx（接受用户请求） mariadb P:php（执行代码） python perl）
软件：
nginx
mariadb（管理数据） mariadb-devel（依赖包） mariadb-server（存数据）
php（用户看数据） php-fpm php-mysql(连接数据库
一．安装软件
yum -y install gcc openssl-devel pcre-devel zlib-devel useradd –s /sbin/nologin nginx cd nginx-1.8.0 ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_ssl_module make && make install yum –y install mariadb mariadb-server mariadb-devel yum –y install php php-mysql tar –xf lnmp_soft-2017-03-28.tar.gz cd lnmp_soft yum –y localinstall php-fpm-5.4.16-36.el7_1.x86_64.rpm
二.启动服务
systemctl stop httpd systemctl disable httpd //关闭httpd的开机启动功能 /usr/local/nginx/sbin/nginx //启动Nginx服务 netstat -utnlp | grep :80 systemctl start mariadb systemctl status mariadb systemctl enable mariadb systemctl start php-fpm systemctl status php-fpm systemctl enable php-fpm
三．构建LNMP平台
配置Fast-CGI支持PHP网页 创建PHP测试页面，测试使用PHP连接数据库的效果 Nginx结合FastCGI技术即可支持PHP页面架构，因此本案例，需要延续练习一的实验内容，通过修改Nginx及php-fpm配置文件实现对PHP页面的支持。 php-fpm需要修改的常见配置如下： vim /etc/php-fpm.d/www.conf listen = 127.0.0.1:9000 listen.allowed_clients = 127.0.0.1 user = apache group = apache pm = dynamic listen = 127.0.0.1:9000 //PHP端口号 pm.max_children = 32 //最大进程数量 pm.start_servers = 15 //最小进程数量 pm.min_spare_servers = 5 //最少需要几个空闲着的进程 pm.max_spare_servers = 32 //最多允许几个进程处于空闲状态 systemctl restart php-fpm systemctl status php-fpm vim /usr/local/nginx/conf/nginx.conf worker_processes 1; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; upstream c{ server 192.168.2.100 weight=1 max_fails=2 fail_timeout=10; server 192.168.2.200 weight=1 max_fails=2 fail_timeout=10; } server { listen 80; server_name www.c.com; location / { } error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } location ~ \.php$ { root html; fastcgi_pass 127.0.0.1:9000; fastcgi_index a.php;动态网站首页 include fastcgi.conf;加载另一部分配置文件 } } server { listen 80; server_name www.a.com; auth_basic "your password:"; auth_basic_user_file "/usr/local/nginx/apass"; ssl_certificate a.crt; ssl_certificate_key a.key; ssl_session_cache shared:SSL:1m; ssl_session_timeout 5m; location / { root ahtml; index index.html index.htm; } } server { listen 80; server_name www.b.com; rewrite ^/(.*) http://www.tmooc.cn/$1; #网站跳转（用于新旧域名连接） rewrite ^/ http://www.tmooc.cn/; #网站跳转（访问旧站页面，重定向至新站下相同的页面 ） ssl_certificate b.crt; ssl_certificate_key b.key; ssl_session_cache shared:SSL:1m; ssl_session_timeout 5m; location / { root bhtml; index index.html index.htm; rewrite /b1.html /b2.html redirect;} #网页跳转 if ($http_user_agent ~* url) { //识别客户端curl浏览器 rewrite ^(.*)$ /curl/$1 break; } } } vim /usr/local/nginx/html/test1.php #测试普通页面 <?php $i="This is a test Page"; echo $i; ?> vim /usr/local/nginx/html/test2.php #测试php页面，连接MariaDB数据库 <?php $links=mysql_connect("localhost","root","密码"); //注意：root为mysql账户名称，密码需要修改为实际mysql密码，无密码则留空即可 if($links){ echo "link db ok!!!"; } else{ echo "link db no!!!"; } ?> vim /usr/local/nginx/html/test3.php #创建PHP测试页面,连接并查询MariaDB数据库 <?php $mysqli = new mysqli('localhost','root','','mysql'); if (mysqli_connect_errno()){ die('Unable to connect!'). mysqli_connect_error(); } $sql = "select * from user"; $result = $mysqli->query($sql); while($row = $result->fetch_array()){ printf("Host:%s",$row[0]); printf("</br>"); printf("Name:%s",$row[1]); printf("</br>"); } ?> echo "I am Normal page" > /usr/local/nginx/html/test.html mkdir -p /usr/local/nginx/html/curl/ echo "I am is curl page" > /usr/local/nginx/bhtml/curl/test.html cp /usr/share/backgrounds/gnome/Road.jpg > /usr/local/nginx/curl/test.jpg /usr/local/nginx/sbin/nginx -s reload firefox http://www.c.com/test1.php #测试php firefox http://www.c.com/test2.php #测试php，连接mariadb库 firefox http://www.c.com/test3.php #测试php，连接并查询mairadb库 firefox http://www.b.com/b1.html #测试跳转页面（地址重写） firefox http://www.b.com/ad
firefox http://192.168.4.5/test.html #针对于修改配置文件(访问192.168.4.5/下面子页面，重定向至www.tmooc.cn/下相同的页面的测试)
针对修改配置文件(实现curl和火狐访问相同连接返回的页面不同的测试：
curl http://192.168.4.5/test.html
