環境:
OS:Centos 7
ES:7.4.2
1.下載二進制安裝包
我這里下載的是:elasticsearch-7.4.2-linux-x86_64.tar.gz
2.解壓縮並創建數據目錄
[root@localhost soft]# tar -xvf elasticsearch-7.4.2-linux-x86_64.tar.gz
[root@localhost soft]# mv elasticsearch-7.4.2 /opt/
[root@localhost soft]#cd /opt/elasticsearch-7.4.2
3.創建用戶
因為啟動es不能在root用戶下啟動,所以要事先創建非root用戶
[root@localhost opt]# useradd esuser
[root@localhost opt]# chown -R esuser.esuser ./elasticsearch-7.4.2/
4.修改配置文件
[esuser@localhost config]$ more elasticsearch.yml
##集群名稱
cluster.name: my-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#節點名稱
node.name: node-1
# Path to directory where to store the data (separate multiple locations by comma):
#數據目錄
path.data: /opt/elasticsearch-7.4.2/data
#日志目錄
path.logs: /opt/elasticsearch-7.4.2/logs
#
# Set the bind address to a specific IP (IPv4 or IPv6):
## 設置綁定的ip,設置為本機的ip
network.host: 192.168.1.118
# Set a custom port for HTTP:
#端口
http.port: 9200
#設置在集群中的所有節點名稱，這個節點名稱就是之前所修改的，當然你也可以采用默認的也行，目前是單機，放入一個節點即可
#注意這里，如果目前是單節點的話，一定要修改該值為節點的名稱，否則雖然啟動成功了，但是通過curl命令向elasticsearch服務中新增數據時，會出現 "master_not_discovered_exception"錯誤
cluster.initial_master_nodes: ["node-1"]
xpack.security.transport.ssl.enabled: true
xpack.security.enabled: true
5.啟動
[esuser@localhost bin]$ ./elasticsearch -d
OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.
6.設置密碼
6.8之后的版本，x-pack已經免費，不需要單獨破解
[esuser@localhost bin]$ ./elasticsearch-setup-passwords interactive

7.驗證
