Build SIA renterd on OmniOSce r151050e

SIA renterd is a decentralized storage tool accessible on Linux and Windows, but it's easy to compile it on last OmniOSce version

Here's how to do it:

Install system dependencies (switch to root):

pkg install pkg:/ooce/developer/go-124 \
            pkg:/developer/versioning/git \
            pkg:/developer/gcc14 \
            pkg:/terminal/tmux

Clone the git repository:

cd /tmp
git clone https://github.com/SiaFoundation/renterd.git
cd renterd/

Configure and compile the project:
(there is a problem with sqlite3 version detection, so we can install it this way)

go install github.com/mattn/go-sqlite3
go mod tidy
go build -v ./...

Specific compilation of the renterd executable:

cd /tmp/renterd/cmd/renterd/
go build

Now, an executable ./renterd has appeared.

Create the destination directory and move the contents of the renterd folder

mkdir -p /opt/renterd/bin
mv /tmp/renterd/* /opt/renterd/
cp /opt/renterd/cmd/renterd/renterd /opt/renterd/bin/

Adjust permissions:

groupadd renterd
useradd -g renterd -d /var/empty -s /bin/bash -c "renterd Daemon" renterd
chown -R renterd:renterd /opt/renterd
chmod -R 750 /opt/renterd

Launch renterd for the first time in a tmux session :
tmux new -s renterd

Start renterd inside tthe tmux session :

usermod -s /bin/bash renterd
su renterd -c 'cd /opt/renterd && /opt/renterd/bin/renterd'

If you want to exit, remember Ctrl+B, then D

When renterd is started, you can securely erase the shell access :
usermod -s /bin/false renterd

The folders and files are created in the location where you launch renterd, which is why it's better to launch them while in the /opt/renterd/bin folder.

To access the web console, you can set up an SSH tunnel (with PuTTy or other) by adding a new forwarded port :

Source port: 9980 (L9980)
Destination: 127.0.0.1:9980.

Open the tunnel, launch your web browser, and type: http://127.0.0.1:9980

You will quickly need to configure a /opt/renterd/bin/renterd.yml file for S3 access (via rclone, for example).
(See the Sia documentation, it's easy)

Use go-124 and gcc14 on OmniOSce, golang and gcc-14 on OpenIndiana for the latest version of renterd,
It works well.

const maxMapSize is now missing on the bolt_solaris.go file.
Then I adapted the howto to add the constant.

majekla

Problem with maxMapSize has been fixed with bbolt 1.4.2.
The howto has been adapted again.

"The folders and files are created in the location where you launch renterd"

You mean it creates its files and folers in /opt? Why? Does it nevessarily have to have root rights?

majekla

When you start renterd without the instruction file renterd.yml, by default it creates files (including the consensus files) in /opt/renterd.
However, you can specify a different location in a file /opt/renterd/renterd.yml if you want the files to be copied elsewhere on the system.

I've just updated the tutorial to use a dedicated renterd user.
It's cleaner this way.

One point, though: since the v2 hardfork, I've been increasingly questioning this solution (Sia renterd)...
