A setting method of REPLICATION in Cyrus-IMAP

[Seiichirou Hiraoka]

Hello. 

There is a question about REPLICATION in Cyrus-IMAP. 

At first, can I  manage Cyrus-IMAP with MASTER-MASTER constitution
with two servers when I use REPLICATION? 

I searched a document and ML, but think that I have you teach it
because only a method to manage as MASTER-SLAVE seems to be carried. 

By the way, I set it in the following examination environment at first
to manage it by MASTER-SLAVE constitution. 

Server: 
  IP:  1.1.1.1 
  The OS:  Solaris9(SPARC) 
  Software:
    Cyrus-IMAP 2.2.10 
      (./configure --disable-gssapi --with-sasl --with-bdb \
         --with-openssl --with-libwrap)
    Cyrus-SASL 2.1.20 
      (./configure --disable-krb4 --disable-gssapi --enable-login \
         --with-pam --with-des --with-openssl)
  Mail Spool:  /var/spool/imap(on NFS) 
  DBs:  /var/imap 

Replica: 
  IP:  1.1.1.2 
  The OS:  Solaris9(SPARC) 
  Software:
    Cyrus-IMAP 2.2.10 
      (The same as above) 
    Cyrus-SASL 2.1.20 
      (The same as above) 
  Mail Spool:  /var/spool/imap(on NFS) 
  DBs:  /var/imap 

I worked as follows. 

1) Setting up Server 

-  /etc/imapd.conf 
configdirectory:  /var/imap 
partition-default:  /var/spool/imap 
admins:  cyrus, cyrus-admin 
sasl_pwcheck_method:  saslauthd 
pop3_tls_cert_file:  /var/imap/server.pem 
pop3_tls_key_file:  /var/imap/server.pem 
imap_tls_cert_file:  /var/imap/server.pem 
imap_tls_key_file:  /var/imap/server.pem 
tls_cert_file:  /var/imap/server.pem 
tls_key_file:  /var/imap/server.pem 
expunge_mode:  delayed 
sync_host:  1.1.1.2 
sync_authname:  cyrus-admin 
sync_password:  password 
sync_log:  1 

- /etc/services
csync           2005/tcp

2) Setting up Replica 

-  /etc/imapd.conf 
configdirectory:  /var/imap 
partition-default:  /var/spool/imap 
admins:  cyrus, cyrus-admin 
sasl_pwcheck_method:  saslauthd 
pop3_tls_cert_file:  /var/imap/server.pem 
pop3_tls_key_file:  /var/imap/server.pem 
imap_tls_cert_file:  /var/imap/server.pem 
imap_tls_key_file:  /var/imap/server.pem 
tls_cert_file:  /var/imap/server.pem 
tls_key_file:  /var/imap/server.pem 

-  /etc/cyrus.conf 
SERVICES { 
  #  add or remove based on preferences 
  imap           cmd="imapd" listen="imap" prefork=0 
  imaps          cmd="imapd -s" listen="imaps" prefork=0
provide_uuid=1 
  pop3           cmd="pop3d" listen="pop3" prefork=0 
  pop3s          cmd="pop3d -s" listen="pop3s" prefork=0 
  sieve          cmd="timsieved" listen="sieve" prefork=0 

  #  these are only necessary if receiving/exporting usenet via NNTP 
#   Nntp          cmd="nntpd" listen="nntp" prefork=0 provide_uuid=1 
#   nntps                 cmd="nntpd -s" listen="nntps" prefork=0 

  #  at least one LMTP is required for delivery 
#   lmtp          cmd="lmtpd" listen="lmtp" prefork=0 
  lmtpunix       cmd="lmtpd" listen="/var/imap/socket/lmtp" prefork=0
provide_uuid=1 

  #  this is only necessary if using notifications 
#   notify        cmd="notifyd" listen="/var/imap/socket/notify"
proto="udp" prefork=1 
   syncserver cmd="/usr/cyrus/bin/sync_server" listen="csync" 
} 
... 

- /etc/services
csync           2005/tcp

3) Start Cyrus-IMAP on Server/Replica
saslauthd -a pam -n 0 & 
/usr/cyrus/bin/master & 

4) Start sync_client on Server

I carry it out in Server as follows 

/usr/cyrus/bin/sync_client -l -v -u username 

Then the following messages display in a terminal 

  1.1.1.2 Can not connect to server '', 15 retrying in seconds 

And the following messages output in /var/log/imapd.log

May 14 15:59:05 Replica syncserver[17840]: [ID 518349 local6.debug]

On Replica side, saslauthd starts with -a pam option, and
cyrus-admin user exist in /etc/passwd.

I am happy as things mentioned above when I can have advice.
