前言

Sp2016的軟件環境要求以下：
服務器場中的數據庫服務器的最低要求：

如下各項之一： ios

Microsoft SQL Server 2014 Service Pack 1 (SP1) 的 64 位版本
Microsoft SQL Server 2016 RTM
Windows Server 2012 R2 Standard 或 Datacenter 的 64 位版本

注意： git

不支持 SQL Server Express
Sql server 2014不包含Powerview 和 PowerPivot 外接程序，若是須要這2個BI要求，請務必安裝Sql Server2016 RTM

瀏覽器

安裝注意事項

命令行PS腳本和SP2016前置離線包放在C盤根目錄下。以下圖 github

注： redis

SP2016前置條件的安裝powershell（sp2016InstallPrerequisiteFiles.ps1）腳本須要修改以下路徑： sql

注意： shell

一、路徑根據本身的實際狀況來修改，以上離線包爲中文環境的離線包，其餘的語言包請自行下載各自的離線包，同時注意離線包的命名跟命令行寫的一致性。附帶下載地址：數據庫

附帶下載這些離線包的PS1腳本（Download-SP2016-Prereqs.ps1）： windows

二、我這個測試安裝環境是windows server 2016+sql server 2016 瀏覽器

若是是windows server 2012 R2,還須要按照以下順序安裝以下KB補丁包，順序以下：
- 首先安裝：Windows8.1-KB2919442-x64.msu
- 其次安裝：Windows8.1-KB2919355-x64.msu（這個安裝過程比較常，由於包有600多M，請耐心等待安裝完成）
- 最後安裝：Windows8.1-KB2999226-x64.msu
若是數據庫是sql server 2014還須要打上補丁SP1包：SQLServer2014SP1-KB3058865-x64-CHS.exe

命令行添加服務角色和功能

打開powershell運行命令，以管理員身份運行以下圖（windows server2016爲例）
運行添加服務器的角色和功能腳本：sp2016EnableWindowsFeatures.ps1，以下圖

若是出現以下表示添加角色和功能成功，以下圖服務器

命令行安裝SP2016的離線包

如何上找到PS1腳本所在的位置，進行安裝就能夠，注意前置條件所在的文件夾以及前置命令行所在的盤符，好比：虛擬光驅

腳本爲：sp2016InstallPrerequisiteFiles.ps1

重啓繼續安裝離線包命令行

腳本爲：sp2016InstallPrerequisiteFilesContinue.ps1，注意前置命令行所在的位置以下圖：

附帶命令行：sp2016EnableWindowsFeatures.ps1
