Pb PHP Warning: PHP Startup: Unable to load dynamic library

su - apache
cd /var/www/plop
php symfony cc
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/php_mapscript.so' - libhdf5.so.6: cannot open shared object file: No such file or directory in Unknown on line 0

On test en changeant le LD_LIBRARY_PATH 

export LD_LIBRARY_PATH=/usr/lib64/mpich/lib/
php symfony cc

Ça marche !

Voir aussi 

env LD_LIBRARY_PATH=/run/current-system/sw/lib:$LD_LIBRARY_PATH
Rendre la manip permanante

Pour ne pas a avoir à exporter systématiquement LD_LIBRARY_PATH

/etc/ld.so.conf.d/mpich-x86_64.conf 

/usr/lib64/mpich/lib
ldconfig

Autres

ldconfig en lecture seule (pas besion de compte root) 

/sbin/ldconfig -NXv |grep mpich

Pb pas d'historique en console pour certains shells

ou pas d'historique en ligne de commande

Un exemple de la console ocaml

Source : http://stackoverflow.com/questions/11757239/how-to-repeat-last-command-in-ocaml-interpreter-shell

Avec la console (ici exemple avec ocaml) pas d'historique.

La flèche du haut me donne les caractères suivants : 

$ ocaml
^[[A

La fléche du bas : 

^[[B

Solution avec rlwrap (GNU Readline)

sudo apt-get install rlwrap
rlwrap ocaml

Ça marche aussi avec Netcat 

rlwrap nc smtp.acme.com 25

Pb OpenVPN démarrage service

Voir Using OpenVPN with systemd

On jette un œil 

dpkg -L openvpn |egrep 'systemd.*service$'

On a la commande 

/usr/sbin/openvpn  --status /run/openvpn/client.status 10 --cd /etc/openvpn --config /etc/openvpn/client.conf

Manuellement ça marche (interface réseau tun, ping…) Ctrl + C 

# systemctl status openvpn@vpn.service
# systemctl start openvpn@vpn.service
Options error: In [CMD-LINE]:1: Error opening configuration file: /etc/openvpn/vpn.conf

/etc/default/openvpn 

# If you're running systemd, changing this variable will
# require running "systemctl daemon-reload" followed by
# a restart of the openvpn service (if you removed entries
# you may have to stop those manually)
#
AUTOSTART="all"

Solution 

systemctl daemon-reload
service openvpn reload
service openvpn@client reload

Si encore pb, penser à utiliser des chemins absolus dans le fichier de conf et s'assurer que l'extension (.conf ou .ovpn !?) soit bonne

Commande aws

Voir :

  • aws-shell
  • cloud-utils

Voir :

Le système doit être à l'heure. Idéalement NTP doit être configuré.

Installation

pip install --user awscli

Générer ~/.aws/config et ~/.aws/credentials 

aws configure --profile os1

~/.aws/config 

[profile os1]
region = eu-west-2
output = text

~/.bash_aliases 

alias aws='aws --endpoint-url https://fcu.eu-west-2.outscale.com --profile os1'

Test 

aws s3 ls
aws ec2 describe-instances --output table
Auto completion

https://docs.aws.amazon.com/fr_fr/cli/latest/userguide/cli-command-completion.html 

complete -C "$VIRTUAL_ENV/bin/aws_completer" aws

Exemple

Forcer l'arrêt 

aws ec2 stop-instances --instance-ids i-39992709 --force

“Terminate” c'est-à-dire effacer la VM (Destruction de la machine !!!) 

aws ec2 terminate-instances --instance-ids i-39992709

Rechercher par “tag” 

aws ec2 describe-instances --filter Name=tag:Name,Values=plop

Plusieurs “Security Group” pour une seul VM 

aws ec2 modify-instance-attribute --instance-id i-fae31a89 --groups sg-8569c41e sg-b25eb0d1

Get InstanceId from volume-id (attached) 

aws ec2 describe-volumes --filters Name=volume-id,Values=vol-0a7d0ea2c73418623 --query 'Volumes[*].Attachments[0].InstanceId' --output text

describe-images 

aws ec2 describe-images --owners self --output json | jq '.Images[] | select(.CreationDate<'$GET_AMI') | {ImageId}' | jq --raw-output '.ImageId'))
 
aws ec2 describe-images --owners 679593333241 --filters 'Name=name,Values=debian-stretch-hvm-x86_64-gp2-*' 'Name=state,Values=available'
 
aws ec2 describe-images --owners=self --filters 'Name=name,Values=packer*' --output text
aws ec2 deregister-image --image-id ami-00f406c198ce29c37
 
aws ec2 describe-instances --filters 'Name=tag-value,Values=*App*' --output table
aws ec2 describe-images --image-ids ami-01f3682deed220c2a
aws ec2 describe-images --owners amazon --filters 'Name=name,Values=amzn2-ami-hvm-2.0.20190612-x86_64-gp2' 'Name=state,Values=available' 'Name=architecture,Values=x86_64' --output text

Debug

Pb OpenStack client API - Debian unable to establish connection to

Pb Debian - Unable to establish connection to

$ openstack service list
Unable to establish connection to https://192.168.51.61:5000/v3/auth/tokens

Mais je ne veux pas me connecter sur https://192.168.51.61:5000/v3/auth/tokens mais sur https://vio.acme.local:5000/v3 ! D'où sort ce 192.168.51.61 ?

Voilà la réponse

          }
        ]
      }
    ]
  }
}

Mais comment cela se fait-il que ça marche sous Ubuntu (paquet plus récent) sans passer par 192.168.51.61:5000 ?

Pour infos (Sur une machine Ubuntu OK)
