Instalação e configuração do ContextNet

Instale o OpenSplice. Instruções mais detalhadas em http://www.lac.inf.puc-rio.br/dokuwiki/doku.php?id=installingdds.

Faça download (ou upload) do arquivo OpenSpliceDDSV6.4.140407OSS-HDE-x86_64.linux-gcc4.6-glibc2.15-installer.tar.gz

Descompacte o arquivo, crie o diretório /opt/OpenSplice e copie o diretório HDE para /opt/OpenSplice

$ tar -xvf VortexOpenSplice-6.9.181127OSS-HDE-x86_64.linux-gcc5.4.0-glibc2.23-installer.tar.gz

$ sudo mkdir /opt/OpenSplice

$ sudo mv HDE /opt/OpenSplice/

O resultado será:

$ ls -l /opt/OpenSplice/

total 4
drwxrwxr-x 3 contextnet contextnet 4096 Apr 14 2014 HDE

Crie um arquivo vazio chamado opensplice.sh e torne o arquivo executável:

$ sudo vi /etc/profile.d/opensplice.sh

$ sudo chmod +x /etc/profile.d/opensplice.sh

Copie o seguinte conteúdo para dentro do arquivo:

OSPL_HOME=/opt/OpenSplice/HDE/x86_64.linux
PATH=$OSPL_HOME/bin:$PATH
LD_LIBRARY_PATH=$OSPL_HOME/lib${LD_LIBRARY_PATH:+:}$LD_LIBRARY_PATH
CPATH=$OSPL_HOME/include:$OSPL_HOME/include/sys:${CPATH:=}
OSPL_URI=file://$OSPL_HOME/etc/config/ospl.xml
export OSPL_HOME PATH LD_LIBRARY_PATH CPATH OSPL_TMPL_PATH OSPL_URI

Edite o arquivo /opt/OpenSplice/HDE/x86_64.linux/etc/config/ospl.xml:

$ sudo cp /opt/OpenSplice/HDE/x86_64.linux/etc/config/ospl.xml{,.velho}

$ sudo vi /opt/OpenSplice/HDE/x86_64.linux/etc/config/ospl.xml

Crie o diretório /opt/ContextNet e copie o ContextNet e o ClientLib para lá com os seguintes comandos:

$ sudo mkdir /opt/ContextNet

$ sudo scp cloud-di@172.16.0.1:Downloads/Contextnet/contextnet-2.5.jar /opt/ContextNet

$ sudo scp cloud-di@172.16.0.1:Downloads/Contextnet/udilib.jar /opt/ContextNet

Resultado:

$ ls -l /opt/

total 8
drwxrwxr-x 2 contextnet contextnet 4096 Apr 15 19:14 ContextNet
drwxr-xr-x 3 root root 4096 Apr 15 18:59 OpenSplice

Opcionalmente, para evitar a mensagem de erro ao iniciar o Gateway do ContextNet, instale a biblioteca SIGAR. Faça upload (ou download) da biblioteca hyperic-sigar-1.6.4.zip ou equivalente para o host a partir de https://sourceforge.net/projects/sigar/files/. Descompacte, mova e muda as permissões com os comandos a seguir (pode ser necessário instalar o unzip):

$ scp cloud-di@172.16.0.1:Downloads/hyperic-sigar-1.6.4.zip .

$ unzip hyperic-sigar-1.6.4.zip

$ sudo mv hyperic-sigar-1.6.4/sigar-bin/lib/*.so /opt/OpenSplice/HDE/x86_64.linux/lib/

$ sudo chmod 775 /opt/OpenSplice/HDE/x86_64.linux/lib/libsigar-*

Reinicie o computador.
