在 Ubuntu/Debian 安裝 NFS Ganesha 取代 NFS-kernel service

這是本文件的舊版！

因為詢問 ChatGPT 詢問是否有提升 NFS 服務效能的輔助軟體, 結果給了一個答案:
使用 NFS 緩存 : 某些軟體和硬體方案提供 NFS 緩存，可減少對伺服器的存取，提升效能。這些緩存可以是軟體層面的，例如 nfs-ganesha 或硬體層面的存儲緩存。
也看到預設 Ubuntu/Debian 可透過 apt 直接安裝, 門檻很低就直接安裝測試

安裝程序

sudo apt update
sudo apt install nfs-ganesha nfs-ganesha-vfs

設定 nfs 分享目錄 Exp. /nfsshare 可讀寫

vi /etc/ganesha/ganesha.conf

EXPORT
{
    Export_ID = 1;
    Path = /nfsshare;
    Pseudo = /nfsshare;
    Access_Type = RW;
    Squash = No_Root_Squash;
    FSAL
    {
        Name = VFS;
    }
}

設定啟動 nfs-ganesha 服務

sudo systemctl start nfs-ganesha
sudo systemctl enable nfs-ganesha

查詢服務狀態
```
sudo systemctl status nfs-ganesha
```

如果服務狀態不是完全正常, 可以查詢 log 了解問題發生的原因: Exp.
```
tail -100 /var/log/ganesha/ganesha.log
```

看範例紀錄

# tail -100 /var/log/ganesha/ganesha.log
