Readme
+------------------------------------------------------------------------------- | Running ${PKGSTEM} on OpenBSD +------------------------------------------------------------------------------- Initial Node/Cluster Configuration ================================== Configuration files are located in ${SYSCONFDIR}/opensearch The security plugin is enabled by default and needs to be configured before starting OpenSearch. For demo/testing purposes, basic security configuration can be created by running: # doas -u _opensearch \ ${TRUEPREFIX}/opensearch/plugins/opensearch-security/tools/install_demo_configuration.sh Upstream documentation: https://opensearch.org/docs/latest/security-plugin/configuration/index By default, OpenSearch binds to a localhost addresses. Since OpenBSD does not support IPv4 to IPv6 address mapping, either IPv4 or IPv6 can be used, but not both of them (see JDK/JRE package README for more details.) Thus by default OpenSearch will bind to 127.0.0.1 and will not be useful for anything except testing. After configuring network.host to non-default localhost address, OpenSearch will assume it's in "production" mode and will enforce the following bootstrap checks: - maximum number of open file descriptors must be >= 65535 (see below) - discovery.seed_hosts and cluster.initial_cluster_manager_nodes must be configured in ${SYSCONFDIR}/opensearch/opensearch.yml Upstream documentation: https://opensearch.org/docs/latest/opensearch/configuration/#configuration-file Resource Limits: File Descriptors ================================= A sample login class has been provided in /etc/login.conf.d/elasticsearch. To raise the default system limit, adjust kern.maxfiles: # sysctl kern.maxfiles=65535 # echo kern.maxfiles=65535 >> /etc/sysctl.conf For a busy OpenSearch node with lots of indexes, maxfiles/openfiles limits should be increased even more, e.g. 131070. You can query the number of open file descriptors along with the maximum allowed by running $ ftp -S dont -o - 'https://admin:admin@localhost:9200/_nodes/stats/process?pretty' and searching for "open_file_descriptors" and "max_file_descriptors" values. Resource Limits: Maximum Number of File Locks ============================================= If you are getting "java.io.IOException: No locks available" errors, increase kern.maxlocksperuid over the default of 1024: # sysctl kern.maxlocksperuid=2048 # echo kern.maxlocksperuid=2048 >> /etc/sysctl.conf OpenSearch Plugins Management ============================= Installing plugins may involve running Java code which can download and execute arbitrary code from the Internet. To avoid running these tasks as root, use doas(1): # doas -u _opensearch \ ${TRUEPREFIX}/opensearch/bin/opensearch-plugin install ... Migrate from ElasticSearch ========================== There are different approaches to migrate from ElasticSearch to OpenSearch. Upstream documents three migration strategies: https://opensearch.org/docs/latest/upgrade-to/index Regardless of the approach choosen, to safeguard against data loss, is recommend to take a snapshot of all indices prior to any migration.
