一、現(xiàn)象
因為 es 不允許使用root用戶安裝，在使用新建的es用戶安裝的時候報錯如下，
max file descriptors [4096] for elasticsearch process is too low, increase to at least [65535]
ERROR: [3] bootstrap checks failed. You must address the points described in the following [3] lines before starting Elasticsearch.
bootstrap check failure [1] of [3]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65535]
bootstrap check failure [2] of [3]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
bootstrap check failure [3] of [3]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, clust二、解決辦法
將當(dāng)前用戶的軟硬限制調(diào)大。找到文件 /etc/security/limits.conf，編輯，在文件的最后追加如下配置：
es soft nofile 65535
es hard nofile 65537![elastic安裝報錯：max file descriptors [4096] for elasticsearch process is too low, increase to at least,隨手筆記,elasticsearch,大數(shù)據(jù),big data](https://imgs.yssmx.com/Uploads/2023/07/515962-1.png)

說明： soft nofile表示軟限制，hard nofile表示硬限制。兩行語句表示，es用戶的軟限制為65535，硬限制為65537，即表示es用戶能打開的最大文件數(shù)量為65537，不管它開啟多少個shell。文章來源地址http://www.zghlxwxcb.cn/news/detail-515962.html
