Cluster Kurrola

Installation

Cluster Kurrola desing targets: easy to manage ( webmin and LTSP are tested and compared ) , get parallel solvers work ( bind9,dhcp,nfs4 ) giganet whit IP4, stabilize system ( Twin Machine , "4G Cantenna mobile internet Antenna,.." server to work outside world at IPV6 and inside IPV4 / IPV6 (wwdial,hostapd,radvd,shoreline,shoreline6) basic servers ( mysql, postresql, apache2, mediawiki, mythweb, calibre ) and wlan services to workstations

To get parallel software like elmerfem and openfoam to work correctly you need full stack ( name services DNS and routing ) of network service and as learnt at practice at twin machine configuration. Twin machine configuration for DHCP ( both ipv4 and ipv6 ), BIND9 ( master and slave ). BIND9 namaserice is needed to have stable routing even connection to global internet breaks. DHCP is used to networkboot and network address managment. To get IPV6 and IPV4 filtered and routed correctly Shoreline and Shoreline6 are simple tool to configure firewall to Linux kernel. You need device level softaware like wvdial to get 4G modem/router to talk whit server routing and brdegeing software as well hostapd to open wlan services. To manage configuration of servers as well workstations webmin is good tool. To get network working well whit software you need common usernamre as well password base to get communication work between machines and services like NFS4 and rsh-redone.

For post prosessing you need Paraview as well support for 3d mouse. That's possible by building Praview 4.0 from sources whit vrpn and hidapi.

Cluster Kurrola ( MPI4YOU ) base parameters:

/mpi3 is directory shared via NFS4 to all nodes
/mpi3/B3 Build Script's for version 3
/mpi3/S3 Source Code version 3
/mpi3/C3 Code Verion 3

Each node has Ubuntu 12.04 LTS ( Long Term Suport version, no need to change OS for 7 years )

Connections

Installing NetworkManager is simple way to get all right for single machine network. I got big supprise when I understood how complex it come to setup STABILE beawulf parallel network to home, you need to setup all network components.

Ubuntu 12.04 have much automation at protocol stack, it finds devices when connected ([udev]) and most cases setups hardware drivers and creates device like eth and ttyUSB. At Cluster Kurrola Installation NetworkManager is totaly removed due instability and some server software incompatibility issues (calibre,mpich3,rsh-redone). What have to do is to glue kernel IPV4 and IPV6 part's together whit devices and give correct parameter's to devices for operation.

Forcing IPv4 when sending to Gmail

If we want to force postfix to use IPv4 instead IPv6 when sending to Gmail, we need to add a line in the main configuration file of postfix like so 1 2

$ sudo nano /etc/postfix/main.cf transport_maps = hash:/etc/postfix/transport

Let’s create this new file and add a new entry in the transport table. Basically, we fore mail for gmail.com to use smtp-ipv4 (which we have to define later, see below) 1 2

$ sudo nano /etc/postfix/transport gmail.com smtp-ipv4:

Here comes the key part. We create a new rule for our new entry and define to use IPv4 protocol explicitly when this rule applies: 1 2 3

$ sudo nano /etc/postfix/master.cf smtp-ipv4 unix .. .. .. .. smtp

-o inet_protocols=ipv4

We need to run the postmap command after the change and reload postfix 1 2

$ sudo postmap /etc/postfix/transport $ sudo postfix reload

BACULA

http://wiki.bacula.org/doku.php?id=faq

What to backup:
/etc/bacula - you need configuration
/var/lib/bacula/bacula.sql - you need backup from database

Crete index at MySql database:

   File.PathId
   File.FilenameId
   Job.FileSetId
   Job.ClientId

MYSQL to SSD

Mysql run on two SSD at server mpi1 and mpi2, asyncronouse mode mpi2 as master.

Innodb's can not be copyed palce to another, directory name must be same if so you can copy from system to other. So do mysqldump, setup new storage system and re-install databases.

Setup:

/etc/mysql/my.cnf datadir=<sdd dir>

datadir         = /media/dbs/mysql

/etc/apparmor.d/abstractions/mysql

  /var/lib/mysql/mysql.sock rw,
  /media/myjohn2/mysql/mysql.sock rw,

/etc/apparmor.d/usr.sbin.mysqld

 /media/dbs/mysql/ r,
 /media/dbs/mysql/** rwk,

/etc/passwd

mysql:x:129:139:MySQL Server,,,:/media/dbs/mysql:/bin/false

cd /media/dbs/mysql/
cp -Rp /var/lib/mysql ./
chown -R mysql:mysql /media/dbs/mysql/
/etc/init.d/apparmor restart
stop mysql
start mysql

rights for slave to replicate:

GRANT REPLICATION SLAVE ON *.* TO 'slave_user'@'%' IDENTIFIED BY 'slave_password';
FLUSH PRIVILEGES;
quit;

LOCK & UNLOCK DATABASE FOR COPYING:

USE wanted; ### IF ONLY ONE
FLUSH TABLES WITH READ LOCK;
SHOW MASTER STATUS;

....COPY DATABASE

UNLOCK TABLES;
quit; 

slave my.cnf

server-id               =2
master-connect-retry    =60
#replicate-do-db         =bacula, mediawiki, kurrola

where to replicate and used user , password:

STOP SLAVE;
RESET SLAVE;
UNLOCK TABLES;
CHANGE MASTER TO MASTER_HOST='192.168.0.100', MASTER_USER='slave_user', MASTER_PASSWORD='slave_password', MASTER_LOG_FILE='mysql-bin.000001', MASTER_LOG_POS=19467;

I have also found that I needed to UNLOCK TABLES on the slave before starting the slave

In trouble do not forget:

 mysql_install_db  -  can fix missing files sometimes

 nano /etc/apparmor.d/local/usr.sbin.mysqld  -  add rights to access new locations for mysql
 service apparmor reload
