nginx虚拟主机

说明：配置之前先把域名解析到服务器IP地址上

站点1：bbs.osyunwei.com 程序所在目录/data/osyunwei/bbs

站点2：sns.osyunwei.com 程序所在目录/data/osyunwei/sns

chown /data/osyunwei/ -R #设置目录所有者，www为nginx运行账户

chmod 700 /data/osyunwei/ -R #设置目录权限

nginx配置文件路径：/usr/local/nginx/conf/nginx.conf

修改之前先备份原来的配置文件cp /usr/local/nginx/conf/nginx.conf /usr/local/nginx/conf/nginx.confbak

一、禁止nginx空主机头

vi /usr/local/nginx/conf/nginx.conf #编辑

找到server，在上面一行添加如下内容：
##############################
server {
listen 80 default;
server_name _;
location / {
root html;
return 404;
}
location ~ /.ht {
deny all;
}
}
##############################

这样设置之后，空主机头访问会直接跳转到nginx404错误页面。

二、添加nginx虚拟主机包含文件

cd /usr/local/nginx/conf/ #进入nginx安装目录

mkdir vhost #建立虚拟目录

vi /usr/local/nginx/conf/nginx.conf #编辑

找到上一步添加的代码，在最后添加如下内容：

include vhost/*.conf;

例如：
##############################
server {
listen 80 default;
server_name _;
location / {
root html;
return 404;
}
location ~ /.ht {
deny all;
}
}
include vhost/*.conf;
##############################

三、修改nginx连接fastcgi的方式为unix domain socket

touch /tmp/php-cgi.sock #建立php-cgi.sock文件

chown /tmp/php-cgi.sock #设置文件所有者为www（必须与nginx的用户一致）

vi /usr/local/nginx/conf/nginx.conf #编辑nginx配置文件

fastcgi_pass 127.0.0.1:9000; 修改为

fastcgi_pass unix:/tmp/php-cgi.sock;//如果使用的是php-fpm需要修改/etc/php/fpm/php-fpm.conf listen /tmp/php-cgi.sock；

vi /usr/local/php5/etc/php-fpm.conf #编辑php-fpm配置文件

listen = 127.0.0.1:9000 修改为

listen =/tmp/php-cgi.sock;

四、修改好之后的/usr/local/nginx/conf/nginx.conf配置文件如下（建议直接使用这个修改好的文件）

user  www www;
worker_processes  2;
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;
#pid        logs/nginx.pid;

events {
    use epoll;
    worker_connections  65535;
}

http {
    include       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  logs/access.log  main;
    server_names_hash_bucket_size 128;
    client_header_buffer_size 32k;
    large_client_header_buffers 4 32k;
    client_max_body_size 300m;
    sendfile        on;
    tcp_nopush     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 128k;
    #keepalive_timeout  0;
    keepalive_timeout  60;
    tcp_nodelay on;
    server_tokens off;
    gzip  on;
    gzip_min_length  1k;
    gzip_buffers     4 16k;
    gzip_http_version 1.1;
    gzip_comp_level 2;
    gzip_types       text/plain application/x-javascript text/css application/xml;
    gzip_vary on;
   server {
     listen       80 default;
     server_name  _;
     location / {
     root   html;
     return 404;
                    }
     location ~ /.ht {
     deny  all;
                      }
       }
   server
        {
     listen       80;
     #server_name localhost;
     index index.php default.php index.html index.htm default.html default.htm ;
     root /data/osyunwei;
location ~ .*\.(php|php5)?$
                        {
                                fastcgi_pass  unix:/tmp/php-cgi.sock;
                                fastcgi_index index.php;
                                include fcgi.conf;
                        }
                location /status {
                        stub_status on;
                        access_log   off;
                }

                location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
                        {
                                expires      30d;
                        }
                location ~ .*\.(js|css)?$
                        {
                                expires      12h;
                        }

                access_log off;
        }

include  vhost/*.conf;
}

五、创建fcgi.conf配置文件

vi /usr/local/nginx/conf/fcgi.conf  #添加以下内容

 

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

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;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;

六、创建虚拟主机配置文件

vi  /usr/local/nginx/conf/vhost/bbs.osyunwei.com.conf   #添加以下内存

server
        {
                listen       80;
                server_name bbs.osyunwei.com;
                index index.php index.html index.htm default.html default.htm default.php;
                root  /data/osyunwei/bbs;
location ~ .*\.(php|php5)?$
                        {
                                fastcgi_pass  unix:/tmp/php-cgi.sock;
                                fastcgi_index index.php;
                                include fcgi.conf;
                        }
                location /status {
                        stub_status on;
                        access_log   off;
                }

                location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
                        {
                                expires      30d;
                        }
                location ~ .*\.(js|css)?$
                        {
                                expires      12h;
                        }

                access_log off;
        }

vi  /usr/local/nginx/conf/vhost/sns.osyunwei.com.conf  #添加以下内容

server
        {
                listen       80;
                server_name sns.osyunwei.com;
                index index.php index.html index.htm default.html default.htm default.php;
                root  /data/osyunwei/sns;
location ~ .*\.(php|php5)?$
                        {
                                fastcgi_pass  unix:/tmp/php-cgi.sock;
                                fastcgi_index index.php;
                                include fcgi.conf;
                        }
                location /status {
                        stub_status on;
                        access_log   off;
                }

                location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
                        {
                                expires      30d;
                        }
                location ~ .*\.(js|css)?$
                        {
                                expires      12h;
                        }

                access_log off;
        }

七、测试

vi /data/osyunwei/bbs/index.php  #新建文件，添加以下内容
phpinfo();
?>
:wq!  #保存退出

vi /data/osyunwei/sns/index.php  #新建文件，添加以下内容
phpinfo();
?>
:wq!  #保存退出

/etc/rc.d/init.d/nginx restart     #重启nginx

/etc/rc.d/init.d/php-fpm restart   #重启php-fpm

打开
