IntroductionRegardless of the function a server is to perform, except STORE, the first step is to mount the STORE to the machine. The first VM to be set up should therefore be the role STORE. First a directory to mount STORE is created. STORE will be mounted in /home/jtel/shared. The path for the mount point is created with the following commands: | Translations Ignore |
|---|
| Code Block |
|---|
mkdir /home/jtel/shared
chown jtel:jtel /home/jtel/shared |
|
Mount with Credentials in fstabThe mount is then configured in the /etc/fstab file. The file can be edited with a text editor, or the following command will append the required line to the file: | Status |
|---|
| colour | Red |
|---|
| title | Caution Password |
|---|
|
| Translations Ignore |
|---|
| Code Block |
|---|
cat <<EOFF >> /etc/fstab
//acd-store/shared /home/jtel/shared cifs user=jtel,password=<password>,uid=jtel,gid=jtel,file_mode=0755,dir_mode=0755 0 0

Notes: - If an external STORE is being mounted, it my be necessary to supply a domain name. In this case add the following in the options part of the fstab entry:
- domain=DOMAINNAME
Mount with external Credentials fileTo mount with the credentials stored in a separate file, proceed as follows. Create a file, for example in /etc/store_credentials with the following content: | Status |
|---|
| colour | Red |
|---|
| title | Caution Password |
|---|
|
| Translations Ignore |
|---|
| Code Block |
|---|
domain=MYDOMAIN
username=jtel
password=<password> |
|
Next, secure the file permissions: | Translations Ignore |
|---|
| Code Block |
|---|
| chown root:root /etc/store-credentials
chmod 400 /etc/store-credentials |
|
And finally, add the /etc/fstab entry: | Translations Ignore |
|---|
| Code Block |
|---|
| title | Secure entry in / etc / fstab |
|---|
| cat <<EOFF >> /etc/fstab
//acd-store/shared /home/jtel/shared cifs credentials=/etc/jtel-credentials,uid=jtel,gid=jtel,file_mode=0755,dir_mode=0755 0 0

Mount STOREThe share can now be mounted. This is done with the command: | Translations Ignore |
|---|
| Code Block |
|---|
| mount /home/jtel/shared |
|
After mounting, a short test shows that the files can be accessed: | Translations Ignore |

| Code Block |

[root@acd-db2 ~]# ls -la /home/jtel/shared/
total 52
drwxr-xr-x. 9 jtel jtel 4096 Mar 30 10:35 .
drwx------. 6 jtel jtel 4096 Jun 12 17:03 ..

Securing the MountAdding the following to crontab will ensure that the mount is restored, even if STORE is rebooted: | Translations Ignore |
|---|
| Code Block |
|---|
| cat <<EOFF >> /etc/crontab
*/1 * * * * root bash -c "if [ ! -d /home/jtel/shared/Data/system ]; then mount /home/jtel/shared ; fi"
EOFF |
|
This can be tested as follows: | Translations Ignore |
|---|
| Code Block |
|---|
| ls /home/jtel/shared
(files are there and are listed)
umount /home/jtel/shared
ls /home/jtel/shared
(files are no longer there and are not listed)
... Wait up to one minute
ls /home/jtel/shared
(files are there and are listed) |
