nginx后端代理多台php-fpm服务器；（补充上一篇博客）

Nginx服务器设置

[[email protected] ~]# yum installnginx #安装nginx

[[email protected] ~]# cd/etc/nginx/

[[email protected] nginx]# vim nginx.conf

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;
    #tcp_nopush     on;
 
    keepalive_timeout  65;
 
    #gzip on;
    
        upstream fastcgiserver { #设置后端php-fpm服务器ip及端口
        server 192.168.10.63:9000;   
        server 192.168.10.64:9000;
        }
        
    include /etc/nginx/conf.d/*.conf;
}

[[email protected] nginx]# cd /etc/nginx/conf.d/

[[email protected] conf.d]# cp default.conf default.conf.bak

[[email protected] conf.d]# vimdefault.conf

    location ~ \.php$ {
        root           /www;     #php-fpm服务器上*.php页面文件存放路径
        #fastcgi_pass   127.0.0.1:9000;
        fastcgi_pass   fastcgiserver;  #这里调用upstream设置；
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }

[[email protected] conf.d]# servicenginx restart   #启动nginx服务

Php-fpm服务器设置（server03和server04一样的配置）

[[email protected]~]# mkdir /www #创建php文件目录

[[email protected]~]# vim /www/index.php #创建php主页，显示php信息

<?php
echo "server03";    #这里仅仅用来识别server03和server04
        phpinfo()
?>

[[email protected]~]# yum install php-fpm  #安装php-fpm

[[email protected]~]# vim /etc/php-fpm.d/www.conf     #配置文件修改

; The address onwhich to accept FastCGI requests.
; Valid syntaxesare:
;   ‘ip.add.re.ss:port‘    - to listen on a TCP socket to a specificaddress on
;                            a specific port;
;   ‘port‘                 - to listen on a TCP socket toall addresses on a
;                            specific port;
;   ‘/path/to/unix/socket‘ - to listen on a unixsocket.
; Note: Thisvalue is mandatory.
;listen = 127.0.0.1:9000
listen = 192.168.10.63  #改成自己的IP地址
 
; List of ipv4addresses of FastCGI clients which are allowed to connect.
; Equivalent tothe FCGI_WEB_SERVER_ADDRS environment variable in the original
; PHP FCGI(5.2.2+). Makes sense only with a tcp listening socket. Each address
; must beseparated by a comma. If this value is left blank, connections will be
; accepted fromany ip address.
; Default Value:any
;listen.allowed_clients =127.0.0.1       
listen.allowed_clients = 192.168.10.66 #设置允许连接到 FastCGI 的服务器 IPV4 地址。如果允许所有那么把这条注释掉即可

[[email protected] ~]# service php-fpm start #启动php-fpm

测试结果：可以看到这里是分别调用了server03和server04两台服务器；每次刷新都会轮询；
