本文介绍了如何配置Nginx进行最基础的负载均衡，包括使用ip_hash和weight权重设置，以及虚拟域名的配置。通过示例展示了在三台服务器之间进行负载均衡的实现方法，强调了负载均衡服务器不能提供自身服务的原则。

遇到的问题一开始写了2个ip 发现始终只能走其中的一个最后才发现原来配置负载均衡的服务器不能自己再提供服务了所以- -

想要负载均衡一般来说需要3台机器第一台是做代理的再提供另外2个服务器配置就可以了

fuzai1 做提供服务代码如下

ip_hash 则这样写

upstream web1{

#ip_hash;
server 192.168.0.203;
server 192.168.0.204;

}
否则如下

http里增加下面这个
upstream web1{

server 192.168.0.203 weight=1;
server 192.168.0.204 weight=1;

}
server里增加

location /{

index index.php index.html index.htm;
root /home/wwwroot/default;
proxy_pass http://web1;

proxy_set_header Host $host;
}

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

        server_names_hash_bucket_size 128;
        client_header_buffer_size 32k;
        large_client_header_buffers 4 32k;
        client_max_body_size 50m;

        sendfile   on;
        tcp_nopush on;

        keepalive_timeout 60;

        tcp_nodelay on;

        fastcgi_connect_timeout 300;
        fastcgi_send_timeout 300;
        fastcgi_read_timeout 300;
        fastcgi_buffer_size 64k;
        fastcgi_buffers 4 64k;
        fastcgi_busy_buffers_size 128k;
        fastcgi_temp_file_write_size 256k;

        gzip on;
        gzip_min_length  1k;
        gzip_buffers     4 16k;
        gzip_http_version 1.1;
        gzip_comp_level 2;
        gzip_types     text/plain application/javascript application/x-javascript text/javascript text/css application/xml application/xml+rss;
        gzip_vary on;
        gzip_proxied   expired no-cache no-store private auth;
        gzip_disable   "MSIE [1-6]\.";

        #limit_conn_zone $binary_remote_addr zone=perip:10m;
        ##If enable limit_conn_zone,add "limit_conn perip 10;" to server section.

        server_tokens off;
        access_log off;



        upstream web1{

                server 192.168.0.203 weight=1;
                server 192.168.0.204 weight=1;

        }




server
    {
        listen 80;
        #listen [::]:80 default_server ipv6only=on;
        server_name www.fk1.com;
        #index index.php index.html index.htm;
        #root  /home/wwwroot/default;

        location /{

                index index.php index.html index.htm;
                root  /home/wwwroot/default;
                proxy_pass http://web1;
                proxy_set_header Host $host;

        }

        #error_page   404   /404.html;

        # Deny access to PHP files in specific directory
        #location ~ /(wp-content|uploads|wp-includes|images)/.*\.php$ { deny all; }

        include enable-php.conf;

        location /nginx_status
        {
            stub_status on;
            access_log   off;
        }

        location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
        {
            expires      30d;
        }

        location ~ .*\.(js|css)?$
        {
            expires      12h;
        }

        location ~ /.well-known {
            allow all;
        }

        location ~ /\.
        {
            deny all;
        }

        access_log  /home/wwwlogs/access.log;
    }
        include vhost/*.conf;
}

虚拟域名配置

[root@localhost conf]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.0.202 www.fk1.com
192.168.0.203 www.fk2.com
192.168.0.204 www.fk3.com

fuzai1的 ip为192.168.0.202

fuzai2的ip为192.168.0.203

fuzai3的ip为 192.168.0.204

接下来每次请求 192.168.0.202
