后端机：B机器上的操作记录：
1）编译安装nginx
[root@B ~]# yum install -y pcre* openssl* gcc gcc+
[root@B ~]# cd /opt/src
[root@B ~]# wget
[root@B ~]# tar -zxvf nginx-1.8.0.tar.gz
[root@B ~]# cd nginx-1.8.0
#添加www用户，其中-M参数表示不添加用户家目录，-s参数表示指定shell类型
[root@nginx-1.8.0 ~]#useradd www -M -s /sbin/nologin
[root@nginx-1.8.0 ~]##vim auto/cc/gcc
#将这句注释掉 取消Debug编译模式 大概在179行
#CFLAGS="$CFLAGS -g"
#我们再配置下nginx编译参数
[root@nginx-1.8.0 ~]# ./configure --prefix=/opt/nginx --user=www --group=www --with-http_stub_status_module --with-http_ssl_module
[root@nginx-1.8.0 ~]#make
[root@nginx-1.8.0 ~]#make install clean
2）配置nginx
[root@nginx-1.8.0 ~]# cd /opt/nginx/conf
注意，把默认的nginx.conf文件中的server区域配置注释掉，设置vhosts虚拟主机的配置，如下：
[root@nginx-1.8.0 conf]# vim nginx.conf
user www;
worker_processes 8;
events {
worker_connections 65535;
}
http {
include mime.types;
default_type application/octet-stream;
charset utf-8;
log_format main '$http_x_forwarded_for $remote_addr $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_cookie" $host $request_time';
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
fastcgi_connect_timeout 3000;

fastcgi_buffers 8 256k;
fastcgi_busy_buffers_size 256k;
fastcgi_temp_file_write_size 256k;
fastcgi_intercept_errors on;
client_header_timeout 600s;
client_body_timeout 600s;
client_max_body_size 100m;
client_body_buffer_size 256k;
gzip on;
gzip_min_length 1k;
gzip_buffers 4 16k;
gzip_http_version 1.1;
gzip_comp_level 9;
gzip_types text/plain application/x-javascript text/css application/xml text/javascript application/x-httpd-php;
gzip_vary on;
include vhosts/*.conf;
}
[root@nginx-1.8.0 conf]# ulimit -n 65535
[root@nginx-1.8.0 conf]# mkdir vhosts
[root@nginx-1.8.0 conf]# cd vhosts
[root@nginx-1.8.0 conf]# vim 8080.conf

location ~ / {

}
}

index index.html index.php index.htm;
}
}
[root@nginx-1.8.0 conf]# vim 80.conf
server {
