掌握Nginx与PHP多站点配置：轻松搭建高效网站集群攻略

Nginx作为一款高性能的Web服务器，与PHP结合可以构建一个高效、可扩展的网站集群。本文将详细讲解如何进行Nginx与PHP的多站点配置，帮助您轻松搭建高效网站集群。

1. Nginx与PHP的关系

Nginx主要负责处理静态文件和反向代理，而PHP则负责处理动态请求。将两者结合，可以实现高性能的动态网站服务。

2. Nginx多站点配置

2.1 安装Nginx

首先，确保您的系统中已安装Nginx。以下是在CentOS系统上安装Nginx的命令：

sudo yum install nginx

2.2 配置Nginx

Nginx的配置文件位于/etc/nginx/nginx.conf。以下是一个简单的多站点配置示例：

user  nginx;
worker_processes  auto;

events {
    worker_connections  1024;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;
    sendfile        on;
    keepalive_timeout  65;

    server {
        listen       80;
        server_name  localhost;

        location / {
            root   /usr/share/nginx/html;
            index  index.html index.htm;
        }

        location ~ \.php$ {
            include /etc/nginx/fastcgi_params;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  /usr/share/nginx/html/$fastcgi_script_name;
        }
    }

    # another virtual host using mix of IP, name, and port
    #
    #server {
    #    listen       8000;
    #    server_name  localhost;
    #
    #    location / {
    #        root   /usr/share/nginx/html/subdir;
    #        index  index.html index.htm;
    #    }
    #}

    # another virtual host redirecting to location above
    #
    #server {
    #    listen       80;
    #    server_name  mysite.com;
    #
    #    location / {
    #        proxy_pass  http://www.mysite.com;
    #    }
    #}
}

2.3 重启Nginx

配置完成后，重启Nginx以使配置生效：

sudo systemctl restart nginx

3. PHP多站点配置

3.1 安装PHP

确保您的系统中已安装PHP。以下是在CentOS系统上安装PHP的命令：

sudo yum install php php-fpm

3.2 配置PHP-FPM

PHP-FPM是PHP的FastCGI进程管理器。以下是PHP-FPM的配置文件示例：

[global]
pid = /var/run/php-fpm.pid
error_log = /var/log/php-fpm/error.log
log_level = warning

[www]
user = nginx
group = nginx
listen = /var/run/php-fpm.sock
listen_owner = www
listen_group = www
pm = dynamic
pm_max_children = 50
pm_start_servers = 10
pm_min_spare_servers = 5
pm_max_spare_servers = 35
request_terminate_timeout = 60
request_timeout = 60

3.3 重启PHP-FPM

配置完成后，重启PHP-FPM以使配置生效：

sudo systemctl restart php-fpm

4. 测试多站点配置

5. 总结

通过本文的讲解，您应该掌握了如何进行Nginx与PHP的多站点配置，从而轻松搭建一个高效网站集群。在实际应用中，您可以根据需求对配置进行调整，以实现更高的性能和稳定性。
