Re: [Pdns-users] Master slave replication
Hi Donald! This is how it works on my setup. I run MariaDB as Generic-MySQL mode "gmysql" in PowerDNS. In pdns.conf should add: launch=gmysql gmysql-host=localhost gmysql-dbname=powerdns gmysql-user=powerdns_user gmysql-password=powerdns_password gmysql-dnssec=yes Now go to MySQL settings on MASTER 192.168.0.1 (where slave will be 192.168.0.2): #Binlog should be in ROW or MIXED format. # Login to MySQL and set in mysql line: mysql -u root -p mysql> SET GLOBAL binlog_format = 'ROW'; # OR mysql> SET GLOBAL binlog_format = 'MIXED' mysql>quit # # Edit your /etc/mysql/my.cnf file nano /etc/mysql/my.cnf # [mariadb] log-bin = mysql-bin bind-address=0.0.0.0 /this allows to listen from any IP, ETH ports and Loopback server_id=1 log-basename=master1 skip-networking=0 # at mysql prompt enter: mysql> GRANT REPLICATION SLAVE ON *.* TO 'replication_user'@'slave_host' IDENTIFIED BY 'password'; FLUSH PRIVILEGES; # # or enter alternative commands GRANT REPLICATION SLAVE ON *.* TO replication_user; GRANT ALL PRIVILEGES ON *.* TO 'replication_user'@'192.168.0.2' IDENTIFIED BY 'password' WITH GRANT OPTION; # #To check replication status: SHOW SLAVE STATUS \G # ### Now, allow 127.0.0.1, and slave SQL 192.168.0.2 ### iptables -A INPUT -p tcp -s 127.0.0.1 --dport 3306 -j ACCEPT iptables -A INPUT -p tcp -s 192.168.0.2 --dport 3306 -j ACCEPT ## Block all other connections to 3306 ## iptables -A INPUT -p tcp --dport 3306 -j DROP #Save iptables sudo iptables-save > /etc/iptables/rules.v4 # service mysql restart ###The Slave settings 192.168.0.2 where maters is 192.168.0.1 # #Now we head over to the Slave.

Hello to all... Ive got a Problem with to servers with powerdns, one is the master, one the slave both use a sqlite backend. Master Slave is not working. If I do for example on the slave: dig @master axfr my.domin.com I will get: ; DiG 9.3.4-P1 @master axfr my.domain.com ; (1 server found) ;; global options: printcmd my.domain.com. 86400 IN SOA master.domain.com. hostmaster.other-domain.com. 0 10800 3600 604800 3600 ;; Query time: 4 msec ;; SERVER: 192.168.123.45#53(192.168.123.45) ;; WHEN: Mon Oct 5 17:16:36 2009 ;; XFR size: 1 records (messages 1) But no A records and other stuff I would expect from axfr.

[Pdns-users] Master/Slave replication
I'm a newb, but found PowerDNS and Poweradmin very nice. I'm having a problem with my Master not updating my slave. I'm on Ubuntu 9.04 pdns was installed via apt, pa was installed via tar, latest version available on the site. Any help would be graciously accepted.
