Zimbra

emicenizo · #1 (**permalink**) 07-28-2011, 09:02 AM

Hi there!

Sooo, first of all, my apologies for the lousy english you are going to read.
I'm trying to install Zimbra on my Linux RedHat; using Bind for splitting those DNS.

I have done EVERY step literally; but i still cant even start installing! The problem is, my "dig address mx" returns "no servers could be reached"; and i have also the "Please fix your /etc/hosts file to contain..." on installing Zimbra.

Step by step, then; these are my configs:

Code:

[root@redHat zcs-7.1.1_GA_3196.RHEL5_64.20110527011124]# cat /etc/resolv.conf
# Generated by NetworkManager
domain server.zimbraloco.com
search server.zimbraloco.com
nameserver 10.0.0.100

Code:

; <<>> DiG 9.7.3-RedHat-9.7.3-2.el6 <<>> server.zimbraloco.com mx
;; global options: +cmd
;; connection timed out; no servers could be reached

Code:

; <<>> DiG 9.7.3-RedHat-9.7.3-2.el6 <<>> server.zimbraloco.com any
;; global options: +cmd
;; connection timed out; no servers could be reached

Code:

[root@redHat zcs-7.1.1_GA_3196.RHEL5_64.20110527011124]# host `hostname`
;; connection timed out; no servers could be reached

Here; my etc/hosts:

Code:

127.0.0.1 localhost.localdomain.com localhost
10.0.0.100 server.zimbraloco.com ecenizo

named.conf:

Code:

options {
        listen-on port 53 { 127.0.0.1; };
        listen-on-v6 port 53 { ::1; };   
        directory       "/var/named";    
        dump-file       "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
        memstatistics-file "/var/named/data/named_mem_stats.txt";
        allow-query     { localhost; };
        recursion yes;

        forwarders { 192.168.0.2; };

        dnssec-enable yes;
        dnssec-validation yes;
        dnssec-lookaside auto;

        /* Path to ISC DLV key */
        bindkeys-file "/etc/named.iscdlv.key";
};

logging {
        channel default_debug {
                file "data/named.run";
                severity dynamic;
        };
};

zone "." IN {
        type hint;
        file "named.ca";
};

zone "server.zimbraloco.com" IN {
            type master;
            file "db.zimbraloco.com";
            allow-update { none; };
        };


include "/etc/named.rfc1912.zones";

zone db.zimbraloco.com:

Code:

$TTL 3h

@       IN      SOA     server.zimbraloco.com. ecenizo.server.zimbraloco.com. (
                               10118      ; Serial
                               43200      ; Refresh
                               3600       ; Retry
                               3600000    ; Expire
                               2592000 )  ; Minimum

;       Define the nameservers and the mail servers
        IN      NS      server.zimbraloco.com.
        IN      MX  10  server.zimbraloco.com.
        IN      A       10.0.0.100

So, any advice, i'm all ears...

Thanks in advance!

Your hosts file is incorrect as is your zone file. You should go to the Split DNS article and follow the instructions in there and as youir dig commands time-out I'd make sure that bind is actually running (and SElinux and the Firewall are both disabled).

So! I literally copied and pasted all the code on the Split-DNS guide. I have this error when starting named, now:

Thanks for those quick replies!

one hint on your zone file: your zonefile does not has a reference for "server.zimbraloco.com."

All right, after reading a lot and using the Search function, i could make it through.

Even "dig" did return something usefull

.

But now! I have a different problem: When installing Zimbra, this one pops:

Code:

Create domain: [zimbraloco.com] ^C

Why does that appears? Then, when trying to start zimbra:

Code:

[zimbra@redHat zzcs-7.1.1_GA_3196.RHEL6_64.20110527010625]$ zmcontrol start
Host localhost
Unable to determine enabled services from ldap.
Unable to determine enabled services. Cache is out of date or doesn't exist.

So, I guess something is still bad on my DNS configuration?

Here's the stuff:

Code:

zimbra@redHat zzcs-7.1.1_GA_3196.RHEL6_64.20110527010625]$ cat /etc/resolv.conf
search zimbraloco.com
nameserver 127.0.0.1

Code:

127.0.0.1 localhost.localdomain localhost

Code:

};

Please! Im SO near (i guess...). What's the last piece of this puzzle?

to get you one step forward:
mail.zimbraloco.com. IN MX 10 mail.zimbraloco.com.

what is the ip of mail.zimbraloco.com

you did see yourself in your dig command, that you do not have a valid mx entry.

So... Still not founding "ns records". Is this the proper way of writing a zone file?

You're not providing enough information to debug your problem. Go to the Split DNS article again and post the output of all the commands in the 'Verify...' section of that article.

According to that information you do not have an MX record for your server and the format of the A record for your server does not use the FQDN. Your hosts file is also incorrect: ou should not have any uppercase letters in your hosts file (it may cause you problems and it's best to change it); the entry for your server does not have your FQDN listed. See the examples in the Split DNS article for the correct format.
