配置elasticsearch

# 1.elasticsearch配置项
root@elk1:~# grep -E "^(path|network|discovery|cluster)" /usr/local/elasticsearch-7.17.28/config/elasticsearch.yml
cluster.name: xu-es-test
path.data: /var/lib/es7
path.logs: /var/log/es7
network.host: 0.0.0.0

# 2.创建elasticsearch启动用户，并设置权限
root@elk1:~# useradd -m elastic
root@elk1:~# id elastic 
uid=1001(elastic) gid=1001(elastic) groups=1001(elastic)
root@elk1:~# chown elastic:elastic  -R /usr/local/elasticsearch-7.17.28/

# 3.创建日志和数据的存放目录
root@elk1:~# install -d /var/{lib,log}/es7 -o elastic -g elastic
root@elk1:~# ll /var/{lib,log}/es7 -d
drwxr-xr-x 2 elastic elastic 4096 Mar 20 15:21 /var/lib/es7/
