nginx反向代理功能使用（二）

12，自定义响应首部 upstream_cache_status; server_addr 通知客户端是由哪个主机代理，代理缓存是否命中。 node1 # vim /etc/nginx/conf.d/default.conf server { listen 80 default_server; server_name _; add_header X-Via $server_addr; 代理服务器的地址 add_header X-Cache $upstream_cache_status; # service nginx reload PS：这里需要开启缓存功能 # vim /etc/nginx/conf.d/default.conf location /bbs/ { proxy_cache mark; proxy_cache_valid 200 1d; proxy_cache_valid 301 302 10m; proxy_cache_valid any 1m; proxy_cache_use_stale error timeout http_500 http_502 http_503 http_504; proxy_pass http://markserver/; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; }

13，fastcgi LNMP 发起对nginx的php请求，nginx会将php代码返回给发起者，为了能够解释php资源，fastcgi能够接收.php文件，而后返回给发起者 这里的php-fpm是安装在nginx代理上的 node1 1，安装php-fpm [cc lang="php"] # yum -y install php-fpm # vim /etc/nginx/nginx.conf 配置文件 # service php-fpm start [/cc] 2，基于fastcgi发送给php # vim /etc/nginx/conf.d/default.conf 启用59行的注释 location ~ .php$ { root html; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name; include fastcgi_params; } 把14行的 root /usr/share/nginx/html;复制到这里 location ~ .php$ { root /usr/share/nginx/html； fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name; include fastcgi_params; } 3，新建测试文件 # cd /usr/share/nginx/html/ # ls 404.html 50x.html index.html nginx-logo.png poweredby.png # mv index.html nginx.html # vim index.php 重读nginx配置 #service nginx reload 4在/etc/nginx下fastcgi_params定义了很多内容 删除fastcgi_params内容，添加如下内容 .,$d # vim /etc/nginx/fastcgi_params [cc lang="php"] fastcgi_param GATEWAY_INTERFACE CGI/1.1; fastcgi_param SERVER_SOFTWARE nginx; fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param SCRIPT_NAME $fastcgi_script_name; fastcgi_param REQUEST_URI $request_uri; fastcgi_param DOCUMENT_URI $document_uri; fastcgi_param DOCUMENT_ROOT $document_root; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param REMOTE_ADDR $remote_addr; fastcgi_param REMOTE_PORT $remote_port; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name; [/cc] # /etc/init.d/nginx reload Reloading nginx: ok 5,在测试就ok了 6，安装php-mysql #yum -y install php-mysql 使用# rpm -ql php-mysql查看.ini文件，打开浏览器查看php页面的Additional .ini files parsed 这项中是否存在php-mysql的.ini文件，如果有，就可以支持mysql了 7,安装mysql #yum -y install mysql-server #service mysqld start #ss -tnl |grep :3306 LISTEN 0 50 *:3306 *:* 8,修改index.php文件 # vim /usr/share/nginx/html/index.php [cc lang="php"] < ?php $conn = mysql_connect('172.0.0.1','root',''); if ($conn) echo succ; else echo fail; mysql_close(); ?> [/cc] 在打开浏览器，运行显示succ，关闭显示fail 14，fastcgi_cache proxy_cache fastcgi_cache node1 interactive 非活动时间 max_size 最大空间 keys_zone=fcgicache:10m 10m大小 #vim /etc/nginx/nginx.conf [cc lang="php"] fastcgi_cache_path /cache/fastcgi/ levels=1:1 keys_zone=fcgicache:10m inactive=3s max_size=1g; [/cc] #vim /etc/nginx/conf.d/default.conf [cc lang="php"] location ~ .php$ { fastcgi_cache fcgicache; fastcgi_cache_valid 200 10m;200响应码缓存10分钟 fastcgi_cache_valid 302 3m; 302响应码，缓存3分钟 fastcgi_cache_valid any 1m; 其他，只缓存1分钟 root /usr/share/nginx/html; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name; include fastcgi_params; } # [/cc]
