Azure Portal

• create new virtual machine, CentOS 6.7
• network rules for ports
• disk drive mount
• iptables

All of these commands require root or sudo!

Create user awips and group fxalpha and create AWIPS directories.

groupadd fxalpha
useradd -G fxalpha awips

or add the existing user to the new group:

groupadd fxalph
usermod -a -G fxalpha awips

/mnt/resource is a temporary scratch disk on Azure Linux VMs, which makes it an ideal spot for the LDM Raw Data Store (since we don't care about losing the files which would be purged within one hour anyway.

mkdir /awips2
ln -s /mnt/resource /awips2/data_store

Mount an Azure SSD to /awips2/edex/datasee dmesg|grep sdc to know if you have one configured):

fdisk /dev/sdc
mkfs -t ext4 /dev/sdc1
mkdir -p /awips2/edex/data
mount /dev/sdc1 /awips2/edex/data

and in fstab

UUID=0ed45b61-1b93-4d5e-a03c-0adc5ffce62a   /awips2/edex/data   ext4   defaults,discard   1   2

where UUID is found with the command ls -al /dev/disk/by-uuid

Your system looks like this now

Filesystem      Size  Used Avail Use% Mounted on
/dev/sda1        30G  2.6G   26G  10% /
tmpfs            28G     0   28G   0% /dev/shm
/dev/sdb1       111G   60M  105G   1% /mnt/resource
/dev/sdc1      1007G   72M  956G   1% /awips2/edex/data

and after install

Filesystem      Size  Used Avail Use% Mounted on
/dev/sda1        30G  8.2G   20G  30% /
tmpfs            28G     0   28G   0% /dev/shm
/dev/sdb1       111G   60M  105G   1% /mnt/resource
/dev/sdc1      1007G  2.3G  954G   1% /awips2/edex/data

• /dev/sda1 will contain the /awips2 software installation
• /dev/sdb1 will contain the LDM raw data store (sym link from /awips2/data_store)
• /dev/sdc1 will contain the EDEX processed sata store (mounted on /awips2/edex/data

2. /etc/sysconfig/iptables

   To serve data from an EDEX server, iptables must allow TCP connections on ports 9581 and 9582. The following lines added to /etc/sysconfig/iptables, followed by the command service iptables restart, will configure iptables for EDEX.

    -A INPUT -p tcp -m tcp --dport 9581 -j ACCEPT
    -A INPUT -p tcp -m tcp --dport 9582 -j ACCEPT
   

Linux Download

For 64-bit RHEL/CentOS 6 and 7, download and run the script awips_install.sh --edex:

wget https://www.unidata.ucar.edu/software/awips2/awips_install.sh
chmod 755 ./awips_install.sh
sudo ./awips_install.sh --edex

This will install to /awips2/edex, /awips2/database/data and other directories.

CentOS/RHEL 6 and 7 are the only supported operating systems for EDEX (Though you may have luck with Fedora Core 12 to 14 and Scientific Linux). Not supported for EDEX: Debian, Ubuntu, SUSE, Solaris, OS X, Fedora 15+, Windows

Be Aware...

• selinux should be disabled (read more about selinux at redhat.com)

• Security Limits - /etc/security/limits.conf

  Qpid is known to crash on systems without a high security limit for user processes and files. The file /etc/security/limits.conf defines the number of each for the awips user (This is automatically configured by the awips_install.sh --edex script).

    awips soft nproc 65536
    awips soft nofile 65536
