安装部署 Office Online Server 集群

既然是集群，首先将域控变成两台：

将AD2加入域中，服务器角色中添加AD域服务，然后将其提升为域控，选择添加到现有域。

集群嘛，多安装几台 Office Online Server，但不导入SSL证书。

在第一台上用管理员打开PowerShell部署 Office Online Server farm

New-OfficeWebAppsFarm -InternalUrl "https://officeonline1.ad.local" -ExternalUrl "https://officeonline.nju.edu.cn" -SSLOffloaded -EditingEnabled

在其它台上用管理员打开PowerShell加入 Office Online Server farm

New-OfficeWebAppsMachine -MachineToJoin "officeonline1.ad.local"

在PowerShell中查看所有节点的状态

(Get-OfficeWebAppsFarm).Machines

前端 Nginx 负载均衡卸载SSL

upstream officeonline {
	ip_hash;
	server 192.168.1.11:80;
	server 192.168.1.12:80;
	server 192.168.1.13:80;
}

map $http_upgrade $connection_upgrade {
	default	upgrade;
	''	close;
}

server {
	listen 80;
	listen [::]:80;
        listen 443 ssl http2;
        listen [::]:443 ssl http2;
	server_name officeonline.nju.edu.cn;

        include ssl/nju_edu_cn.conf;

	location / {
		proxy_pass http://officeonline;
		proxy_http_version 1.1;
		proxy_set_header Upgrade $http_upgrade;
		proxy_set_header Connection $connection_upgrade;
		proxy_cache_bypass $http_upgrade;
		proxy_set_header Host $host;
		proxy_set_header X-Real-IP $remote_addr;
		proxy_set_header X-Real-PORT $remote_port;
		proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
		proxy_set_header X-Forwarded-Proto $scheme;
	}
