1、在a上的设置
yum install nginx
nginx ---启动服务
vim /etc/nginx/nginx.conf
proxy_cache_path /var/lib/nginx/tmp/pcache levels=1:1:2 keys_zone=proxycache:20m inactive=120s max_size=1g;
fastcgi_cache_path /var/lib/nginx/tmp/fastcgicache levels=1:2:2 keys_zone=fastcgicache:20m inactive=120s max_size=1g;
upstream webserver {
server 172.18.21.106:80 weight=2;
server 172.18.21.7:80;
}
vim /etc/nginx/conf.d/vhost.conf
server{
listen 80 default_server;
server_name www.a.com;
root /app/website1;
location ~* \.(html|jpg)$ {
proxy_pass http://webserver;
proxy_cache proxycache;
proxy_cache_key $request_uri;
proxy_cache_valid 200 301 302 1h;
proxy_cache_valid any 1m;
}
location ~* \.php$ {
fastcgi_pass 172.18.21.6:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /app/php$fastcgi_script_name;
include fastcgi_params;
fastcgi_cache fastcgicache;
fastcgi_cache_key $request_uri;
fastcgi_cache_valid 200 301 302 1h;
fastcgi_cache_valid any 1m;
}
}
nginx -t
nginx -s reload
2、在两台apache服务器上的设置
yum install httpd
cd /var/www/html
vim index.html ---制作好网页的页面
systemctl start httpd
systemctl enable httpd
3、在d上的设置
yum install php-fpm php-mysql
vim /etc/php-fpm.d/www.conf
listen = 9000
;listen.allowed_clients = 127.0.0.1 ---将这一行用分号注释掉，默认是允许任何人访问
service php-fpm start
chkconfg php-fpm on
mkdir /app/php ---创建存放php程序的主目录
cd /app/php
vim test.php
<?php
$conn = mysql_connect('172.18.21.88','wpuser','centos');
if ($conn)
echo ok;
else
echo notok; ---注意not ok不能分开写，只能连着写才有效
mysql_close();
phpinfo();
?>
4、在e上的设置
yum install mysql-server
service mysqld start
chkconfig mysqld on
mysql
mysql> create database wpdb;
mysql> grant all on wpdb.* to wpuser@172.18.21.6 indentified by "centos";
mysql> quit
5、在浏览器上测试
http://www.a.com/index.html ---因为有缓存，所有总是访问的同一个realserver，把缓存关闭就可以看到轮询模式了
http://www.a.com/test.php ---看到连接数据库成功
