위의 방식으로 되지 않아서 다른 방법 찾는중

그런데 yum clean all 은 웬지 설치된 패키지 전부 지우는 느낌인데..

 

sudo yum check-update
sudo yum clean all
sudo reoot
sudo yum update

저번주 까지만 해도 멀쩡히 잘 되었던 녀석이 갑자기 안된다.

그래서 찾아보는데.. 아무래도 구버전이 되어서 live에서 내려가 버린듯..

실행하다 보면 /usr/libexec/warewulf/wwmkchroot/*.tmpl을 건드리는데

그 경로를 하나씩 내려가다 보니 아래와 같이 BaseOS 다음에 platform architecutre 구분이 들어가게 된다.

mirror.centos.org/centos-8/8/BaseOS/

mirror.centos.org/centos-8/8/BaseOS/aarch64/

mirror.centos.org/centos-8/8/BaseOS/x86_64/

 

해당 부분에 대해서는

$basearch 변수를 사용하는데 그걸 바꾸어서 적용하면 임의로 크로스 플랫폼(?)으로 적용이 가능할 지도 모르겠다.

 

And also need to change $YUM_MIRROR to the local repository.

Corresponds to wwmkchroot written in "3.6 Define compute image for provisioning" of each Usage.

[root@aarch64 /]# export YUM_MIRROR=""/repos/centos-<version>.<release>/BaseOS", "/repos/centos-<version>.<release>/AppStream", "/repos/centos-<version>.<release>-aarch64/PowerTools""
[root@aarch64 /]# wwmkchroot -d centos-<version> $CHROOT

나머지는 uname -r로

# uname -r
4.18.0-193.el8.x86_64

커널 버전과 아키텍쳐를 받아와서 티가 안나는데

초기 설치하는 패키지가 다르다.

 

[sms]# yum install http://repos.openhpc.community/OpenHPC/2/CentOS_8/x86_64/ohpc-release-2-1.el8.x86_64.rpm

[sms]# yum install http://repos.openhpc.community/OpenHPC/2/CentOS_8/aarch64/ohpc-release-2-1.el8.aarch64.rpm

 

혹시나 해서 x86 linux에 aarch64 패키지를 설치해 보았지만 역시나 에러가 발생한다.

dose not have a compatible architecture

문서 자체가 arm64 코어 기반 하드웨어가 node master여야 하는 듯..

cross 나오는것 봐서는 x86-64에서 aarch64의 VNFS를 만들도록 하는 내용 같긴한데..

라이선스는 GPL

네트워크 모니터링에서 시작한것 같긴한데

결국에는 모든 장치에 대한 모니터링 까지 제공하는 듯?

currently it provides:

Monitoring of network services (SMTP, POP3, HTTP, NNTP, ICMP, SNMP, FTP, SSH)
Monitoring of host resources (processor load, disk usage, system logs) on a majority of network operating systems, including Microsoft Windows, using monitoring agents.
Monitoring of any hardware (like probes for temperature, alarms, etc.) which have the ability to send collected data via a network to specifically written plugins
Monitoring via remotely run scripts via Nagios Remote Plugin Executor
Remote monitoring supported through SSH or SSL encrypted tunnels.
A simple plugin design that allows users to easily develop their own service checks depending on needs, by using their tools of choice (shell scripts, C++, Perl, Ruby, Python, PHP, C#, etc.)
Available data graphing plugins
Parallelized service checks
Flat-text formatted configuration files (integrates with many config editors)
The ability to define network host using 'parent' hosts, allowing the detection of and distinction between hosts that are down or unreachable
Contact notifications when service or host problems occur and get resolved (via e-mail, pager, SMS, or any user-defined method through plugin system)
The ability to define event handlers to be run during service or host events for proactive problem resolution
Automatic log file rotation
Support for implementing redundant monitoring hosts
Support for implementing performance data graphing
Support for database backend (such as NDOUtils)
Push notifications[6]
A web-interface for viewing current network status, notifications, problem history, log files, etc.

nagios enterprise 사 버전이라고 해야하려나?

nagios XI 등은 구매가 가능한데 비용은 안나오고 양식을 채워넣으라고만 하니 알수가 없다. 

github 버전도 라이선스 있어야 하는지 좀 더 조사가 필요하다

# wwnodescan
USAGE: /usr/bin/wwnodescan [options] nodes....
    SUMMARY:
        Scan for new systems making DHCP requests.

    GENERAL OPTIONS:
        -h, --help              Show the help/utilization summary
        -d, --debug             Display debugging information
        -v, --verbose           Be more verbose in output
        -f, --file <file>       Create Warewulf script instead of auto-import
        -l, --listen <iface>    Interface to listen on (tcpdump -D for list)
        -c, --tcpdump <cmd>     Specify the full path to the tcpdump command
        -T, --tshark <cmd>      Specify the full path to the tshark command (Only IB Mode)
        -x, --max [<cnt>]       Exit after <cnt> new nodes (0 for auto)

    MODES:
        -t, --test              Test mode; do not modify data store
        -r, --replace           Replace existing nodes (by name)
        -a, --autoconfig        Assign HW addresses to unassigned nodes
        -I, --infiniband        Use tshark to look for Client Identifier, compatible with Mellanox FlexBoot.

    SETTINGS:
        -n, --netdev <dev>      Network device for the new node(s)
        -i, --ipaddr <addr>     IP address for the new node(s)

        You can scan for any number of nodes; this program will exit after all
        specified nodes have been found.  The IP address provided will be
        incremented for each node found, and nodes will be added in the order
        given on the command line.

    DEFAULTS:
        As with all object types, you can create a template node object called
        DEFAULT whose attributes will be used as the default values for all
        new nodes.  You can override some of these defaults using the options
        shown above.

    EXAMPLES:
        # wwnodescan --ipaddr 10.0.1.10 --netmask 255.255.0.0 --vnfs=sl6.vnfs
            --bootstrap=`uname -r` n0000 n0001

        # wwsh node new DEFAULT --groups=grp1,test
        # wwsh provision node DEFAULT --vnfs=sl6.vnfs --bootstrap=`uname -r`
        # wwnodescan --ipaddr 10.0.1.100 --netmask 255.255.0.0 n00[02-19]

wwmkvnfs 로 만든 디렉토리를 VNFS 이미지로 생성하는 유틸리티

# wwvnfs
_FORTIFY_SOURCE requires compiling with optimization (-O) at /usr/lib64/perl5/features.ph line 207.
USAGE: /usr/bin/wwvnfs [options] (name)

OPTIONS:

   -c, --chroot      Path to the chroot to use for this VNFS image
   -r, --root        Alias for --chroot
   -h, --help        Usage and help summary
   -o, --output      Output the binary VNFS to a file instead of importing it
                     directly into Warewulf
   -e, --exclude     Exclude a file or directory from the VNFS image
       --excludefile Path to a file that contains a list of files and directories to
                     exclude from the VNFS image
       --hybridize   Hybridize a list of files or directories from the VNFS image
                     (requires --hybridpath to be set, or files are just excluded)
       --hybridizefile Path to a file that contains a list of files and directories to
                     be hybridized from the VNFS image
       --hybridpath  Path to use within the VNFS where the links will be pointed to in
                     the final image (this needs to be added to the VNFS fstab!)

NOTES:

   When wwvnfs is run for the first time on a VNFS, it will attempt to create a
   configuration file in the default warewulf config dir (/etc/warewulf/vnfs/) or in
   the users ~/.warewulf/vnfs directory. Once the configuration file has been written
   and updated, you can simply run 'wwvnfs [vnfs_name]' to rebuild the image. You can
   temporarily override any of these options via command line arguments.

EXAMPLES:

   # wwvnfs --chroot=/var/chroots/rhel-6
   # wwvnfs custom_name --chroot=/var/chroots/rhel-6 --hybridpath=/hybrid/vnfs_name
   # wwvnfs --chroot=/var/chroots/rhel-6 --output=rhel-6.vnfs
   # wwvnfs custom_name

# wwlivesync
USAGE: /usr/bin/wwlivesync (options) [targets]

SUMMARY:

     The live sync command will spawn rsync commands to update the running node
     operating system (VNFS) live. This command should only be used for minor VNFS
     updates, as large updates including library load could potentially break binary
     compatibility.


OPTIONS:

   -l, --lookup        Identify nodes by specified property (default: "name")
   -f, --files         Pass a list of files to sync instead of the entire VNFS
       --show          Just print what it would do instead of actually do it
       --logdir        Directory of per-node logs (/var/log/wwlivesync)
       --verbose       Increase verbosity level
       --quiet         Decrease verbosity level
       --debug         Print debugging messages
   -h, --help          Display this usage summary

TARGETS:

     The target(s) specify which node(s) will be affected by the chosen
     action(s).  By default, node(s) will be identified by their name(s).
     Use the --lookup option to specify another property (e.g., "hwaddr"
     or "groups").

     All targets can be bracket expanded as follows:

         n00[0-99]       All nodes from n0000 through n0099 (inclusive)
         n00[00,10-99]   n0000 and all nodes from n0010 through n0099


EXAMPLES:
