Normally you will use SSH public key authentication to connect to Dirvish clients. However there are cases where this is not possible, for example on webhosting packages. You might be lucky to have SSH access with password authentification at all, hopefully along with rsync so a Dirvish backup is possible.
This instructions were tested with a Dirvish server on debian 10 (buster), and a webgo.de webhosting package „pro“. But basically it should work with any linux distro on server side and any webhosting package that includes a SSH access and rsync, probably with small modifications.
The sample parameters used are:
First do a normal SSH from your Dirvish server to the client. Accept adding the client to the list of known hosts:
# ssh web999@s999.goserver.host ... Are you sure you want to continue connecting (yes/no)? yes ... web999@s999.goserver.host's password: ssh_passwd ... web999 # exit #
Install sshpass:
# apt install sshpass
Save ssh password into a file:
# echo 'ssh_passwd' > /etc/dirvish/web999.pass # chmod 0400 /etc/dirvish/web999.pass
Test if working so far:
# sshpass -f /etc/dirvish/web999.pass ssh web999@s999.goserver.host web999 # exit #
Edit your clients Dirvish config file, and add the `rsh` parameter as:
# mkdir -p /backup/web999/dirvish # nano /backup/web999/dirvish/default.conf --- client: web999@s999.goserver.host tree: ~/www/ exclude: trash/** cache/** tmp/** rsh: sshpass -f /etc/dirvish/web999.pass ssh -l web999
Add web999 as vault under _Runall_ in /etc/dirvish/master.conf.
You should now be able to run your init command:
# dirvish --vault web999 --init
Typically webhosting packages also include mysql (mariadb) databases. If you are lucky to have access to the mysql and mysqldump programs in SSH, you can save your databases too.
The sample parameters used are:
Create pre-client script:
# nano /backup/web999/dirvish/pre-client --- #!/bin/bash for db in $( mysql -uweb999 -psql_passwd -e 'show databases' -s \ | grep -v 'Database' \ | grep -v 'mysql' \ | grep -v 'information_schema' \ | grep -v 'performance_schema' \ ) do mysqldump -uweb318 -psql_passwd --default-character-set=utf8mb4 --no-tablespaces -B $db > ~/www/$db.sql done
Create post-client script:
# nano /backup/web999/dirvish/post-client --- #!/bin/bash for db in $( mysql -uweb999 -psql_passwd -e 'show databases' -s \ | grep -v 'Database' \ | grep -v 'mysql' \ | grep -v 'information_schema' \ | grep -v 'performance_schema' \ ) do rm -f ~/www/$db.sql done rm -f ~/www/dirvish.pre-client rm -f ~/www/dirvish.post-client
Make scripts executable:
# chmod 755 /backup/web999/dirvish/pre-client # chmod 755 /backup/web999/dirvish/post-client
Finally update the config file to use the scripts as:
# nano /backup/web999/dirvish/default.conf --- client: web999@s999.goserver.host tree: ~/www/ exclude: dirvish.pre-client dirvish.post-client trash/** cache/** tmp/** rsh: sshpass -f /etc/dirvish/web999.pass ssh -l web999 pre-server: ; for prefix in pre post ; do rsync --rsh "sshpass -f /etc/dirvish/web999.pass ssh -l web999" ../../dirvish/$prefix-client $DIRVISH_CLIENT:~/www/dirvish.$prefix-client ; done ; exit 0 post-server: ; exit 0 pre-client: ; ~/www/dirvish.pre-client post-client: ; ~/www/dirvish.post-client
