如果此時敲入指令行 ./elasticsearch來啟動時,會有可能出現如下問題:
1) [3]: max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144]
這是由于程序的虛拟記憶體空間不足。
修改配置檔案 : # vim /etc/sysctl.conf
在下面添加: vm.max_map_count=262144
然後執行 # sysctl -p
2)[1] bootstrap checks failed
[1]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured
這時候繼續編輯elasticsearch.yml檔案,将 #cluster.initial_master_nodes: ["node-1", "node-2"] 修改為 cluster.initial_master_nodes: ["node-1"],記得儲存
