1. 启动 elasticsearch 命令:
[root@localhost bin]$ ./elasticsearch-7.6.2/bin/elasticsearch -d
2. 停止 elasticsearch 命令:
首先需要利用JAVA的 jps 命令工具,查看到 Elasticserach的进程ID,再用 kill 命令杀进程
[tangjunhua@localhost bin]$ jps
30180 Jps
29417 Elasticsearch
[tangjunhua@localhost bin]$ kill -9 29417
3. 更改密码
首先,需要修改elasticsearch.yml的配置文件,增加 discovery.type: single-node,否则会报错。
[tangjunhua@localhost bin]$ vim ../config/elasticsearch.yml
xpack.security.enabled: true
discovery.type: single-node
[tangjunhua@localhost bin]$ ./elasticsearch-setup-passwords interactive
