我的Linux生活日記 26.分享資料夾-autofs
昨天已經安裝完 nfs server 接下來就是其他主機安裝端點工具啦！有兩個處理方式：mount 以及 autofs。
mount
mount 指令如下：
madir -p /mnt/nfs/centos7
mount 192.168.56.173:/share /mnt/nfs/centos7
但是不建議這樣做，主要是網路不通無法掛載遠端目錄時會在成PRC服務逾時，間接拖垮系統效能。接下來是建議使用 autofs 掛載目錄。
安裝
- Debian
sudo apt install autofs
- CentOS7
sudo yum install autofs
編輯設定文件
這邊我直接新增文件，如果沒有 /etc/auto.master.d 這個目錄可以進入 /etc/auto.master 這份文件直接編輯
- /etc/auto.master.d/jc-share.autofs
# [掛載目錄] [遠端配置文件] [參數]
/mnt/nfs /etc/jc-share.nfs --timeout=10
上述文件中 /mnt/nfs 不需要特別新增，autofs會在掛載時自動處理。
- /etc/jc-share.nfs
# [資料夾名稱] [掛載參數] [遠端主機分享目錄]
centos7 -fstype=nfs,vers=4,rw 192.168.56.173:/share
測試
sudo automount -f -v
- 失敗畫面
Starting automounter version 5.1.2, master map /etc/auto.master
using kernel protocol version 5.03
lookup(file): failed to read included master map auto.master
mounted indirect on /mnt/nfs with timeout 10, freq 3 seconds
attempting to mount entry /mnt/nfs/centos7 # >> 當有呼叫 /mnt/nfs/centos7 才會去掛載
mount(nfs): no hosts available
failed to mount /mnt/nfs/centos7 # 掛載失敗訊息
re-reading map for /mnt/nfs
- 成功畫面

啟動 autofs 服務
測試麼有問題後就可以開啟服務啦！
- Debian 10, CentOS 7
sudo systemctl restart autofs
sudo systemctl start autofs
sudo systemctl enable autofs
- centOS 6
/etc/init.d/autofs stop && /etc/init.d/autofs start
/etc/init.d/autofs status
chkconfig aufofs on
掛載 Cifs
- /etc/auto.master.d/bakerst.autofs
/bakerst /etc/auto.bakerst
- /etc/auto.bakerst
cases -fstype=cifs,credentials=/secure/sherlock ://serverX/cases
- 新增檔案 /secure/sherlock，內容如下：(only root access, permission 600)
username=[UserName]
password=[Password]
domain=[DomainName]
Accessing Network Storage with SMB
錯誤訊息
- automount: program is already running.
代表 autofs 已經啟動
- CentOS6.5 掛載 cifs 會失敗
cifs mount works on 6.8, but not on 6.5
