集群部署

负载均衡(nginx 1.11.2)：

文件结构如下，content文件为网站静态资源文件夹，nginx.conf为配置文件。

nginx.conf内容如下：

#user  nobody;
# multiple workers works !
worker_processes  8;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

#pcre_jit on;

events {
    worker_connections  8192;
}


http {
    ## 其他配置
    include       mime.types;
    default_type  application/octet-stream;
    client_max_body_size 100M;  ## 页面如果要上传大文件，要加上该属性。
    sendfile        off;
    server_names_hash_bucket_size 128;
    map_hash_bucket_size 64;
    client_body_timeout   10;
    client_header_timeout 10;
    keepalive_timeout     30;
    send_timeout          10;
    keepalive_requests    10;


     ## 添加两个负载均衡服务，每个管理两个站点（权重weight用来设置负载比例）
     upstream jrlc8811{
         server 10.10.131.40:10045 weight=100 fail_timeout=5;
         server 10.10.131.19:10045 weight=100 fail_timeout=5;
         least_conn;
     }

         least_conn;
     }

共享session：

另外，需要确认该机器的注册表值正确，端口号值要一致（注册表中为16进制）。

 [HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesaspnet_stateParameters]

结束后重启ASP.NET 状态服务，设为自启。

 共享文件：

1. 在每个站点服务器建立同名，同密码的帐号。并选择账户所有者。

在运行中输入lusrmgr.msc打开本地用户和组管理界面

 

创建账户，密码选择“永不过期”

 

用户属性中，添加隶属账户“administrators”

 

在每个站点所属的程序池添加标识用户。

 

 在作为文件服务器的机器，创建网络共享文件夹。

创建文件夹，并添加everyone及IUSER_SHARE权限

 

文件夹属性中添加网络共享。

 

 为IIS的默认站点添加虚拟目录，路径选择共享文件夹

 

启用iis中的目录浏览

 

部分文件无法读取的情况下，添加crossdomain.xml文件，至虚拟目录所在站点的根目录下（Default Web Site）

 

内容如下（星号*代表允许所有域名的访问）：

<?xml version="1.0" encoding="utf-8"?>
<cross-domain-policy> 
    <allow-access-from domain="*"/>  
</cross-domain-policy>
