I want to configure backup of the Alfresco database (PostgreSQL rdbms).
For that I have a script like this:
psql-create-backup:
#!/bin/sh
pg_dump -h localhost -U postgres -Fc -Z9 -c -f /home/bykovan/alfresco-data-backup/"`date +%d-%m-%Y`".alfresco.backup alfresco
I saved it in /home/bykovan and gave rights to execute:
[bykovan@docflow ~]$ sudo chmod 711 psql-create-backup
Then I added the job to cron:
[bykovan@docflow ~]$ sudo crontab -e
...
0 0 * * * /home/bykovan/psql-create-backup
In the pg_hba.conf I added this line host all all 127.0.0.1/32 trust:
[bykovan@docflow ~]$ sudo vi /var/lib/pgsql/9.5/data/pg_hba.conf
-- SKIPPED --
# TYPE DATABASE USER ADDRESS METHOD
# "local" is for Unix domain socket connections only
#local all all peer
local all all md5
# IPv4 local connections:
#host all all 127.0.0.1/32 ident
host all all 127.0.0.1/32 trust
host all all 127.0.0.1/32 md5
# IPv6 local connections:
#host all all ::1/128 ident
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local replication postgres peer
#host replication postgres 127.0.0.1/32 ident
#host replication postgres ::1/128 ident
host all all 192.168.0.0/16 md5
-- VISUAL BLOCK --
Backups are empty:
[bykovan@docflow alfresco-data-backup]$ ls -lh
-rw-r--r-- 1 root root 0 feb 18 00:00 18-02-2017.alfresco.backup
-rw-r--r-- 1 root root 0 feb 19 00:00 19-02-2017.alfresco.backup
-rw-r--r-- 1 root root 0 feb 20 00:00 20-02-2017.alfresco.backup
-rw-r--r-- 1 root root 0 feb 21 00:00 21-02-2017.alfresco.backup
In the pg_hba.conf I added this lines:
host all all ::1/128 md5
host all postgres 127.0.0.1/32 trust
Then restart service:
[bykovan@docflow ~]$ sudo service postgresql-9.5 stop
Redirecting to /bin/systemctl stop postgresql-9.5.service
[bykovan@docflow ~]$ sudo service postgresql-9.5 start
Redirecting to /bin/systemctl start postgresql-9.5.service
Then ran command direct in the prompt (I was prompted for the password) and saw the following:
[bykovan@docflow alfresco-data-backup]$ ls -lh
-rw-r--r-- 1 root root 0 feb 17 18:39 17-02-2017.alfresco.backup
-rw-r--r-- 1 root root 0 feb 18 00:00 18-02-2017.alfresco.backup
-rw-r--r-- 1 root root 0 feb 19 00:00 19-02-2017.alfresco.backup
-rw-r--r-- 1 root root 0 feb 20 00:00 20-02-2017.alfresco.backup
-rw-r--r-- 1 root root 0 feb 21 19:41 21-02-2017.alfresco.backup
-rw-r--r-- 1 root root 667K feb 22 07:04 22-02-2017.alfresco.backup
But running the task via cron gave me the empty files...
Where I'm wrong?
I set the password in the script, it now looks like this:
PGPASSWORD="some_password" pg_dump -h localhost -U postgres -Fc -Z9 -c -f /home/bykovan/alfresco-data-backup/"`date +%d-%m-%Y`".alfresco.backup alfresco
Now everything is Ok.
