eldap missing in package

[spham]

hi i use rhel 7,

• https://github.com/rabbitmq/erlang-rpm/releases/tag/v23.3.4.4 and source on 23.3.4.4 and get from packagecloud

and ls /usr/lib/rabbitmq/lib/rabbitmq_server-3.8.17/plugins | grep eldap return nothing

[michaelklishin]

eldap is a part of Erlang/OTP, it is not supposed to be under RabbitMQ installation's plugins directory.

[michaelklishin]

Whether eldap is present in an Erlang installation can be verified without involving RabbitMQ:

erl

# and then run in the shell:
# application:ensure_all_started(eldap).

I'm trying to reproduce using centos:7 from DockerHub.

[michaelklishin]

I cannot reproduce:

1> application:ensure_all_started(eldap).
{ok,[eldap]}

I used the Cloudsmith version of the instructions from this package's README.

My best guess is that your Erlang installation does not come from this package. See

yum list erlang

to see what versions of the erlang package are available and from what repositories.

i have this

yum list erlang
Modules complémentaires chargés : enabled_repos_upload, package_upload, product-id,
                                : search-disabled-repos, subscription-manager,

Cannot upload enabled repos report, is this client registered?

ans now

[ansible@adrmq01d ~]$ erl
Erlang/OTP 23 [erts-11.2.2.3] [source] [64-bit] [smp:2:2] [ds:2:2:10] [async-threads:1] [hipe]

Eshell V11.2.2.3  (abort with ^G)
1> application:ensure_all_started(eldap)
1> 

i will try now with cloudsmith,

I don't understand , how on install erlang before rabbitmq-server, it will deploy on rabbitmq-server

[michaelklishin]

I could not reproduce using PackageCloud either, which is not surprising given that only one package is produced and then published to both services.

[michaelklishin]

@spham you are missing the trailing dot after application:ensure_all_started(eldap). It is mandatory as it completes the expression. In other words, you get no result because you haven't entered a complete expression.

I'm afraid I do not understand this part

how on install erlang before rabbitmq-server, it will deploy on rabbitmq-server

RabbitMQ has a dedicated Installation guide for RPM distributions. CentOS 7 is no longer officially supported as it cannot run Erlang 24 with TLS 1.3 but CentOS 7 RPM packages are still produced for RabbitMQ 3.8 and Erlang 23. Nothing has changed in that are for either RabbitMQ or this package in a while.

[michaelklishin]

Here is what exactly you have to enter into the Erlang shell before hitting Enter:

application:ensure_all_started(eldap).

(note the trailing dot).

I'm afraid I don't have much time to spend on this. eldap is available in this package, as it should be.

yes,

i try now and it's ok

1> application:ensure_all_started(eldap). {ok,[eldap]}

but why is ok enable plugin is not possible ?

 sudo rabbitmq-plugins enable eldap
Enabling plugins on node rabbit@adrmq01d:
eldap
Error:
{:plugins_not_found, [:eldap]}

i use rhel7.9 and old erlang-23.3.4.4-1.el7.x86_64.rpm and rmq 3.8.17

ok, it maybe available in erlang, but rabbitmq-server need this pagackage in /usr/lib/rabbitmq/lib/rabbitmq_server-3.8.17/plugins

sudo find / -iname 'eldap*'
/usr/lib64/erlang/lib/eldap-1.2.9
