Hi I have running a mirrored ispconfig like http://www.howtoforge.com/perfect-server-debian-squeeze-with-bind-and-courier-ispconfig-3 . how can i add now 1 more server (without email.)? is there also a way to integrate openexchange? Thanks & Best regards
You can add as many slaves to a server as you like, the setup is always the same. I dont think so, at least not without rewriting a lot of code in openexchange or ispconfig.
i just wonder about the mysql setup since i added on the master one slave shall i add one more here then or who does it work On server 1: vi /etc/mysql/my.cnf Search for the section that starts with [mysqld], and put the following options into it (commenting out all existing conflicting options): [...] [mysqld] server-id = 1 replicate-same-server-id = 0 auto-increment-increment = 2 auto-increment-offset = 1 master-host = 192.168.0.106 master-user = slaveuser master-password = slave_user_password master-connect-retry = 60
Mysql master / master setups with more then 2 servers are possible, but they tend to be unstable in my experience. So I would try to avoid such a setup. If you want to try it anyway, see e.g. here: http://www.howtoforge.com/setting-u...ion-on-four-nodes-with-mysql-5-on-debian-etch Another option might be something like that, but I did not try tungsten replicator yet: http://www.howtoforge.com/how-to-se...mysql-high-availability-on-ubuntu-10.04.3-lts
