這篇是一個把 R Studio Server 裝在 LXD 底下的 CentOS8 Container 的紀錄。
安裝：
1. 先裝 EPEL-Release Repo：裡面有官方維護的 R 套件。不過要安裝 R，在 CentOS 8 要啟用 PowerTools Repo 才行。
在 CentOS 8 的 R，背後的 BLAS 函式庫已經使用 OpenBLAS 了～相信速度會比 CentOS 7 的改善許多。
此外，雖然 RHEL/CentOS 8 已經跟 Fedora 一樣使用 dnf 作套件管理，不過 yum 指令仍然向下相容～

2. 接著安裝 RStudio-Server（到這裡找安裝檔）
lab@lxdlab:~$ lxc exec rstudio -- yum install -y https://download2.rstudio.org/server/fedora28/x86_64/rstudio-server-rhel-1.2.5033-x86_64.rpm

Complete!
lab@lxdlab:~$
這樣就裝完了。
以下切進去 container 裡面進行。
3. 驗證安裝
lab@lxdlab:~$ lxc shell rstudio [root@rstudio ~]# rstudio-server verify-installation 25 Mar 2020 10:29:40 [rsession-rstudio-server] WARNING Unable to determine LANG (proceeding with no LANG set; LOGGED FROM: void rstudio::core::r_util::ensureLang() /var/lib/jenkins/workspace/IDE/open-source-pipeline/v1.2-patch/src/cpp/core/r_util/REnvironmentPosix.cpp:856 [root@rstudio ~]#
指令執行後沒有特殊的抱怨就是可以了。上面的抱怨只是 LXC Container 裡面的 locale 設定都是 C，也就是沒設定，無傷大雅～
這時 R Studio Server 會以自己的帳號執行
[root@rstudio ~]# tail -1 /etc/passwd rstudio-server:x:998:995::/home/rstudio-server:/bin/bash [root@rstudio ~]# [root@rstudio ~]# tail -1 /etc/group rstudio-server:x:995: [root@rstudio ~]#
4. R Studio Server 的 Port 預設是 8787，要變更的話，可以增加到 R Studio Server 的設定檔。我這邊不做更改，僅紀錄變更方式
[root@rstudio ~]# echo "www-port=80" >> /etc/rstudio/rserver.conf
因為這邊在 LXD 環境運作，因此要將服務轉發出來
lab@lxdlab:~$ lxc config device add rstudio rstudio-ui proxy listen=tcp:0.0.0.0:8787 connect=tcp:localhost:8787 Device rstudio-ui added to rstudio lab@lxdlab:~$
5. 接著建立一個「新」帳號，用來提供登入 RStudio-Server
R Studio Server 預設將使用帳號跟 OS 帳號透過 PAM 認證連動，因此需要建立帳戶，掛到 rstudio-server 這個 User Group 下。如果需要 LDAP 的帳號連動認證功能，需要裝企業版。
[root@rstudio ~]# useradd ruser --shell /sbin/nologin -g rstudio-server
[root@rstudio ~]# passwd ruser
* CentOS7 之後沒有 --disabled-login 選項，於是直接把 shell 指向 nologin既有 OS 帳號 <username> 使用
[root@rstudio ~]# usermod -a -G rstudio
6. 最後，啟用服務
不過在安裝完畢時，就已經啟動了～
[root@rstudio ~]# service rstudio-server start
Redirecting to /bin/systemctl start rstudio-server.service
[root@rstudio ~]#
這邊一樣，雖然從 RHEL/CentOS 7 之後就使用討厭的 SystemD，但舊的 SysV 的 service 指令仍然相容～7. 用瀏覽器開到 http://<server-ip>:8787 網頁就好了：這邊轉發出來，因此服務會在 LXD Host 上看到
Note：RStudio-Server 需要 /tmp 能任意讀寫（權限 777），以及家目錄權限是帳號自己的
8. 要安裝 R 教學 swirl 套件：需要安裝 libcurl-devel 與 openssl-devel 的 Linux 套件，才有辦法裝（會編譯 RCurl 跟 httr）
[root@rstudio ~]# yum install -y libcurl-devel openssl-devel
