# Deploying in the bare metal | ||
|
||
Suppose you don't have the Kubernetes environment or some container-based system. You can try to deploy Oxia with the bare metal environment. | ||
|
||
> The oxia coordinator only supports the file, k8s config map, and memory metadata. Therefore, We only suggest using it for testing or POC. | ||
|
||
## Download code from the GitHub | ||
|
||
You can check https://github.com/streamnative/oxia to download the source of StreamNative oxia. | ||
|
||
## Build from the source code | ||
|
||
Change the directory to the root directory of StreamNative oxia project. | ||
|
||
```shell | ||
cd <directory>/oxia | ||
``` | ||
|
||
Then run the command as follows to build the project by source code. | ||
|
||
```shell | ||
make | ||
``` | ||
|
||
After building, you'll see a bin directory at the project's root. | ||
|
||
```shell | ||
oxia/ | ||
├── bin/ | ||
│ ├── oxia | ||
└── ... | ||
``` | ||
|
||
## Deploying oxia storage node | ||
|
||
We should deploy the oxia storage node first. We can start three storage nodes for primary usage. the command is as follows. | ||
|
||
```shell | ||
# storage-node-0 | ||
./bin/oxia server -i 0.0.0.0:6649 -p 0.0.0.0:6648 -m 0.0.0.0:8080 --wal-dir "<wal-dir-path>" --data-dir "<data-dir-path>" | ||
# storage-node-1 | ||
./bin/oxia server -i 0.0.0.0:6661 -p 0.0.0.0:6660 -m 0.0.0.0:8081 --wal-dir "<wal-dir-path>" --data-dir "<data-dir-path>" | ||
# storage-node-2 | ||
./bin/oxia server -i 0.0.0.0:6663 -p 0.0.0.0:6662 -m 0.0.0.0:8082 --wal-dir "<wal-dir-path>" --data-dir "<data-dir-path>" | ||
``` | ||
|
||
The command explanation is as follows: | ||
|
||
```shell | ||
Usage: | ||
oxia server [flags] | ||
|
||
Flags: | ||
--data-dir string Directory where to store data (default "./data/db") | ||
--db-cache-size-mb int Max size of the shared DB cache (default 100) | ||
-h, --help help for server | ||
-i, --internal-addr string Internal service bind address (default "0.0.0.0:6649") | ||
-m, --metrics-addr string Metrics service bind address (default "0.0.0.0:8080") | ||
-p, --public-addr string Public service bind address (default "0.0.0.0:6648") | ||
--wal-dir string Directory for write-ahead-logs (default "./data/wal") | ||
--wal-retention-time duration Retention time for the entries in the write-ahead-log (default 1h0m0s) | ||
|
||
Global Flags: | ||
-j, --log-json Print logs in JSON format | ||
-l, --log-level string Set logging level [disabled|trace|debug|info|warn|error|fatal|panic] (default "info") | ||
--profile Enable pprof profiler | ||
--profile-bind-address string Bind address for pprof (default "127.0.0.1:6060") | ||
``` | ||
## Deploying oxia coordinator | ||
|
||
Since the coordinator is brain-like in the oxia cluster, it should have some configurations to help it to make decisions. | ||
|
||
We can create it in the specific path you need. the configuration template is as follows. | ||
|
||
```yaml | ||
namespaces: | ||
- name: default | ||
initialShardCount: 3 # This configuration indicates the number of shards for keys across the namespace. | ||
replicationFactor: 3 # This configuration indicates the number of replicas for of key-shard. | ||
servers: | ||
# storage-node-0 | ||
- public: 127.0.0.1:6648 | ||
internal: 127.0.0.1:6649 | ||
# storage-node-1 | ||
- public: 127.0.0.1:6660 | ||
internal: 127.0.0.1:6661 | ||
# storage-node-2 | ||
- public: 127.0.0.1:6662 | ||
internal: 127.0.0.1:6663 | ||
``` | ||
|
||
> If you need to know what the namespaces are. You can check the [architecture](https://github.com/streamnative/oxia/blob/main/docs/architecture.md) section to get more information. | ||
|
||
After configuration file creation, we can start the coordinator. The command is as follows. | ||
|
||
```shell | ||
./bin/oxia coordinator --conf "<conf-file>" --file-clusters-status-path "<cluster-status-file-path>" --metadata file -i 0.0.0.0:6664 -m 0.0.0.0:8083 | ||
``` | ||
|
||
The command explanation is as follows: | ||
|
||
```shell | ||
Usage: | ||
oxia coordinator [flags] | ||
|
||
Flags: | ||
-f, --conf string Cluster config file | ||
--conf-file-refresh-time duration How frequently to check for updates for cluster configuration file (default 1m0s) | ||
--file-clusters-status-path string The path where the cluster status is stored when using 'file' provider (default "data/cluster-status.json") | ||
-h, --help help for coordinator | ||
-i, --internal-addr string Internal service bind address (default "0.0.0.0:6649") | ||
--k8s-configmap-name string ConfigMap name for metadata configmap | ||
--k8s-namespace string Kubernetes namespace for metadata configmap | ||
--metadata MetadataProviderImpl Metadata provider implementation: file, configmap or memory (default file) | ||
-m, --metrics-addr string Metrics service bind address (default "0.0.0.0:8080") | ||
|
||
Global Flags: | ||
-j, --log-json Print logs in JSON format | ||
-l, --log-level string Set logging level [disabled|trace|debug|info|warn|error|fatal|panic] (default "info") | ||
--profile Enable pprof profiler | ||
--profile-bind-address string Bind address for pprof (default "127.0.0.1:6060") | ||
``` | ||
|
||
## Go for testing | ||
|
||
After all of the components are up and running without an error log. We can use oxia-perf to test. the command is as follows. | ||
|
||
```shell | ||
./bin/oxia perf --rate 10000 | ||
``` | ||
|
||
|
||
Well done, please enjoy your powerful oxia cluster. |
