Nginx + PHP 配置负载均衡

proxy_pass 模式

upstream httpserver {
        ip_hash;
        server 172.20.39.79 weight=1;
        server 172.20.39.80 weight=1;
        server 172.20.39.81 weight=1;
}

server
    {
        listen 80;
        server_name xxx.abc.com *.xxx.abc.com;
        index index.html index.htm index.php default.html default.htm default.php;
        root  /data/www/xxx/Public;

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

        location / {
                proxy_set_header Host $host:$server_port;

                proxy_set_header X-Real-IP $remote_addr;

                proxy_set_header REMOTE-HOST $remote_addr;

                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

                proxy_pass http://httpserver;
        }

        #access_log  /data/wwwlogs/xxx.abc.com.log;
    }


fastcgi_pass 模式

注意：该模式必须保证在nginx服务器上有php服务器上对应的被请求php文件（只要能找到对应文件名即可，不需要php文件内容相同，空文件即可），主要是因为nginx会检查文件是否存在，单入口模式的系统，只要有index.php就可以了

nginx 配置，服务器IP 172.20.39.78

upstream phpserver {
        ip_hash;
        server 172.20.39.79:9000 weight=1;
        server 172.20.39.80:9000 weight=1;
        server 172.20.39.81:9000 weight=1;
}

server
    {
        listen 80;
        server_name xxx.abc.com *.xxx.abc.com;
        index index.html index.htm index.php default.html default.htm default.php;
        root  /data/www/xxx/Public;

        location / {
            if (!-e $request_filename) {
                rewrite ^/(.*)$ /index.php/$1 last;
                break;
            }
        }

        location ~ /uploads/.*\.php$ { deny all; }

        location ~ [^/]\.php(/|$)
        {
            fastcgi_pass  phpserver;
            fastcgi_index index.php;
            include fastcgi.conf;
            include fastcgi_params;
            fastcgi_param PHP_ADMIN_VALUE "open_basedir=/data/www/xxx/:/tmp/:/proc/";
            include pathinfo.conf;
        }

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

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

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

        location ~ /\.
        {
            deny all;
        }

        access_log  /data/wwwlogs/xxx.abc.com.log;
}


php-fpm.conf 配置 服务器IP 172.20.39.80，其他两台服务器类似

[global]
pid = /usr/local/php/var/run/php-fpm.pid
error_log = /usr/local/php/var/log/php-fpm.log
log_level = notice

[www]
listen = 9000
listen.backlog = -1
listen.allowed_clients = 127.0.0.1,172.20.39.80,172.20.39.78
listen.owner = www
listen.group = www
listen.mode = 0666
user = www
group = www
pm = dynamic
pm.max_children = 120
pm.start_servers = 30
pm.min_spare_servers = 30
pm.max_spare_servers = 90
pm.max_requests = 1024
pm.process_idle_timeout = 10s
request_terminate_timeout = 60
request_slowlog_timeout = 0
slowlog = /data/logs/php_slow.log

 

listen = 127.0.0.1:9000,172.20.39.80:9000 # fpm 监听端口（本机网卡IP），多个IP逗号分隔。可用格式为: ‘ip:port’, ‘port’, ‘/path/to/unix/socket’
listen.allowed_clients = 127.0.0.1,172.20.39.80,172.20.39.78 # 允许访问 FastCGI 进程的 IP（本机IP或其他主机IP），多个IP逗号分隔。如果需要其他主机也能访问，除这里需要写入其他主机IP外，上面的 listen 配置里面也必须有本机网卡IP，不能只有127.0.0.1的回环网卡地址，因为其他主机是无法访问本机的回环地址的。
