| 4 | - Forge svn repository access |
|---|
| 5 | - add Unix user |
|---|
| 6 | - adduser -m -d /home/cscompute -s /sbin/nologin cscompute |
|---|
| 7 | - check if EPEL repository is configured, if not, do steps below |
|---|
| 8 | - for CENTOS 6 |
|---|
| 9 | (from http://www.tecmint.com/how-to-enable-epel-repository-for-rhel-centos-6-5/) |
|---|
| 10 | - wget http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm |
|---|
| 11 | - rpm -ivh epel-release-6-8.noarch.rpm |
|---|
| 12 | - note |
|---|
| 13 | - |
|---|
| 14 | - if you get error below |
|---|
| 15 | Could not parse metalink https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=x86_64 error was |
|---|
| 16 | No repomd file |
|---|
| 17 | - then, manually copy files below from another machine |
|---|
| 18 | - repomd.xml |
|---|
| 19 | - metalink.xml |
|---|
| 20 | - tools |
|---|
| 21 | - yum install gcc screen |
|---|
| 22 | - this program uses rabbitmq-c library (v0.3.0) |
|---|
| 23 | - https://github.com/alanxz/rabbitmq-c |
|---|
| 24 | - library installation |
|---|
| 25 | - using system package |
|---|
| 26 | - install using commands below |
|---|
| 27 | - yum install librabbitmq0 |
|---|
| 28 | - yum install librabbitmq-dev |
|---|
| 29 | - note that it is likely that system packages versions are out of date (we need v0.3.0) |
|---|
| 30 | in this case, use installation from source |
|---|
| 31 | - from source |
|---|
| 32 | - retrieve source |
|---|
| 33 | - wget https://github.com/alanxz/rabbitmq-c/archive/rabbitmq-c-v0.3.0.zip -O rabbitmq-c-v0.3.0.zip |
|---|
| 34 | - unzip rabbitmq-c-v0.3.0.zip |
|---|
| 35 | - cd rabbitmq-c-v0.3.0 |
|---|
| 36 | - compilation using autoconf (automake v1.9+, and libtool v2.2+) |
|---|
| 37 | - autoreconf -i |
|---|
| 38 | - if error occurs at this step, check requirement below |
|---|
| 39 | - we require autotools v2.63 or better to build. I think RHEL5 ships with v2.59 which lacks the AC_PROC_CC_C99 macro. |
|---|
| 40 | - You can do one of two things; |
|---|
| 41 | - Install a newer version of autotools |
|---|
| 42 | - Build using cmake (v2.6 or better). |
|---|
| 43 | - ./configure --enable-static |
|---|
| 44 | - make |
|---|
| 45 | - make install |
|---|
| 46 | - compilation using cmake (CMake v2.6+) |
|---|
| 47 | - mkdir build && cd build |
|---|
| 48 | - cmake -DBUILD_STATIC_LIBS=True -DBUILD_SHARED_LIBS=True .. |
|---|
| 49 | - cmake --build . |
|---|
| 50 | - make |
|---|
| 51 | - you got error AAA below, it's normal |
|---|
| 52 | make[2]: *** Pas de rÚgle pour fabriquer la cible « librabbitmq/librabbitmq.so.1.0.1 », nécessaire pour « examples/amqp_bind ». Arrêt. |
|---|
| 53 | make[1]: *** [examples/CMakeFiles/amqp_bind.dir/all] Erreur 2 |
|---|
| 54 | make: *** [all] Erreur 2 |
|---|
| 55 | - make |
|---|
| 56 | (because of the above error (AAA), you need to run make twice) |
|---|
| 57 | - make install |
|---|
| 58 | - sendAMQPMsg installation |
|---|
| 59 | - svn co svn+ssh://<login here>@forge.ipsl.jussieu.fr/ipsl/forge/projets/libigcm/svn/trunk/Monitoring/CNClient |
|---|
| 60 | - compilation (static) |
|---|
| 61 | - gcc -static -I/usr/local/include -L/usr/local/lib -Wall -o sendAMQPMsg send_AMQP_msg.c -lrabbitmq |
|---|
| 62 | - we get warning below during compilation |
|---|
| 63 | - |
|---|
| 64 | <--- |
|---|

|---|
| 67 | linked applications requires at runtime the shared libraries from the glibc version used for linking |
|---|
| 68 | ---> |
|---|
| 69 | - it means that you may need to be sure all computing node have the same glibc version !!!! |
|---|
| 70 | - also means that a different binary must be use in each computing center |
|---|
| 71 | - usage |
|---|
| 72 | - to send a message in the queue, do |
|---|
| 73 | - ./sendAMQPMsg localhost 5672 test |
|---|
| 74 | - note |
|---|
| 75 | - to show how many messages are in the queue, do as root |
|---|
| 76 | - ./rabbitmqctl list_queues |
|---|
