tar -xzf elasticsearch-8.8.1-linux-x86_64.tar.gz -C /usr/local/
cd /usr/local
ln -s elasticsearch-8.8.1 elasticsearch

创建基础目录

mkdir /mnt/data2/esdata/{data,logs}
mkdir /mnt/data2/kibana/{data,logs}

创建账户并赋权

useradd esadmin
chown -R esadmin.esadmin /usr/local/elasticsearch*
chown -R esadmin.esadmin /mnt/data2/esdata

ES配置修改

jvm.options
