bash 腳本編程十七 NFS client自動部署

1.自動檢測並安裝nfs-common，

2.自動創建目錄並mount

3.同時檢查/etc/fstab文件中是否有配置，沒有則加入。確保下次開機能自動mount。

install.sh腳本：

1. #!/bin/bash
3. source ../../common/tool.sh
5. nfsClient="nfs-common"
6. nfsServerFolder=10.112.18.158:/opt/share
7. nfsClientFolder=~/test_nfs_dir
9. hasDpkg $nfsClient
10. r=$?
12. if [ $r -eq 1 ]
13. then
14. echo "$nfsClient was installed"
15. else
16. echo "$nfsClient was not installed"
17. apt-get install $nfsClient
18. fi
21. #config /opt/share as nfs folder
22. createFolder $nfsClientFolder
23. mount -t nfs4 $nfsServerFolder $nfsClientFolder
25. mountString="$nfsServerFolder $nfsClientFolder nfs rsize=8192,wsize=8192,timeo=14,intr"
26. searchString="$nfsServerFolder"
27. mountConfigFile="/etc/fstab"
29. findStringInFile $searchString $mountConfigFile
30. m=$?
32. if [ $m -eq 1 ]
33. then
34. echo "auto mount was configured"
35. else
36. echo "auto mount was not configured, configuring..."
37. echo $mountString >> $mountConfigFile
38. fi

這裡用了一個新函數: findStringInFile

這個新函數放在tool.sh腳本中：

1. #$1 search string
2. #$2 file path
3. #return 1 if found
4. #return 0 if not found
5. function findStringInFile {
6. h=`grep "$1" $2`
7. echo "h: $h"
8. if [ -n "$h" ]
9. then
10. return 1
11. else
12. return 0
13. fi
14. }
