Hi all, i want to set up two server from diffrent location one master and one slave . i need to obtain redundancy and when the first server goes down must to work the second and when the secondary server goes down work to primary, and when work both obtain redundancy. here i explain what i do: to my registrat i tell ns1.xdigital.ro 89.122.18.58 ns2.xdigital.ro 86.34.232.110 that's my public ip where is located my servers on my ispconfig to first server i set up: *Management->Server->Settings Hostaname ns1 Domain xdigital.ro Ip 89.122.18.58 IP List 89.122.18.58 86.34.232.110 DNS tab on default Ns1 89.122.18.58 default ns2 86.34.232.110 *ISP Manager->ISP Site->Hostname www Domain xdigital.ro IP 89.122.18.58 *DNS Manager->xdigital.ro as a primary domain Domain SOA xdigital.ro IP 89.122.18.58 In Option tab i set up Nameserver 1: ns1.xdigital.ro Nameserver 2: ns2.xdigital.ro On the Records tab i set up the A record Hostname www IP 89.122.18.58 Hostname mail same IP Hostname ns1 same IP at MX i set up host mail.xdigital.ro 10 priority on my ispconfig to second server i set up: *Management->Server->Settings Hostaname ns1 Domain xdigital.ro Ip 86.34.232.110 IP List 89.122.18.58 86.34.232.110 DNS tab on default Ns1 89.122.18.58 default ns2 86.34.232.110 *ISP Manager->ISP Site->Hostname www Domain xdigital.ro IP 86.34.232.110 *DNS Manager->xdigital.ro as a slave domain Domain SOA xdigital.ro IP master DNS 89.122.18.58 This is all but doesn't work my domain xdigital.ro. On the same server i have other domain wich is working fine. where am i wrong? thank's in advance
What you're doing is roundrobin DNS, i.e., you have two different IP addresses for your domain in DNS. This does not provide high-availability, because if one server goes down, and a user's PC gets the IP address of that server, he cannot reach your site. If oyu want high-availability, you need a load balancer with a virtual IP address: http://www.howtoforge.com/high-availability-load-balancer-haproxy-heartbeat-debian-etch
Hi Falko Thank's for you reply, but I don't have debian, i work with centos 4.6, and i want to make with that 2 static IP, two servers DNS,WEB,FTP,Mail, and i need when master server goes down, work slave server and vice versa. How can i made this with centos and ISPConfig? Thank's
As I said before, you need a load-balancer with a virtual IP. This might work for CentOS: http://www.howtoforge.com/high-availability-load-balancer-haproxy-heartbeat-fedora8
ok thank's ok thank's for that tutorial but is working with ISPConfig? Because i have ISPConfig installed on both server And for Mail and ftp it's working ? And what happened when one client modify mysql databases meenwhile one server is down? the secondary server will send all modification to the primary when is up?
You must make your services (http, smtp, etc.) listen on the virtual IP address. Regarding MySQL, you can set up master-master replication: http://www.howtoforge.com/mysql5_master_master_replication_debian_etch
and all tutorials is for debian. why? centos is not so good? debian is very complicated, cmd line is too much command key...and so on. security is same to microsoft windows = doesn't work. security for me is the best when it's work, and filter what i need and block what i don't need. but in windows block everything, that is not security for me. and debian is the same.so exist tutorial for centos?
I have no idea what you're trying to tell me. Debian is not more or less secure than CentOS. This should work for CentOS as well: http://www.howtoforge.com/high-availability-load-balancer-haproxy-heartbeat-fedora8
for example i want to copy the site in www under debian, and i have no rights.debian tell me i have not permission to copy.why? why i can't login as root? that is wrong security for me, is stop all access for me. in centos i can login as root, i can copy all files in www...and so on sorry for my english i'm romanian. i will read carefully that tutorial and i have one question. to make that it is possible with two servers and two ip, or i need more. and it's working with Public IP, or it's working just in my internal network. for that i must configure additional IP under ISP Config(from tutorial a.k.a the perfect server)? and that ip belong to another server from my network? or just change my network card IP. thank's
You can login as root unser debian. I'am doibg this daily on many servers. You might mix up Debsain an ubuntu linux, under ubuntu the root user is disabled by default, but you just have to run the passwd command and set a password to enable it.
what is this answer???? i ask if i can login as root in debian and you told me for use ssh or putty? ??? i'm confuse....
You asked how you can login and not if you can login and my post above answered that. To your new question, yes you can login as root user in debian
login ok I wondering if i could login as root in debian xserver (gnome) because i cannot. how can i do it? thank's
