Ubuntu 18.04 LTS 安装 Elasticsearch6.x

Posted 2021-01-03 tcppdu

1.   添加Elasticsearch GPG Key

第一步，使用以下命令导入Elasticsearch GPG密钥：

 

$ wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add - 

 

2.   添加Elasticsearch 6.x APT存储库

第二步，导入GPG密钥后，添加apt存储库：

$ echo“deb https://artifacts.elastic.co/packages/6.x/apt stable main”| sudo tee -a /etc/apt/sources.list.d/elastic-6.x.list

 

3.   安装OpenJDK

第三步，Elasticsearch基于Java开发的，因此需要先安装JDK

 

$ sudo add-apt-repository ppa:webupd8team/java  # 导入jdk密钥
$ sudo apt update #更新库缓存
$ sudo apt install openjdk-8-jdk #安装jdk

  

4.   安装Elasticsearch 6.x.

$ sudo apt install elasticsearch

安装完成后，进入 /etc/elasticsearch/elasticsearch.yml进行参数配置

如果进入不到该文件，请将权限更改或者分配给普通用户

$ sudo chown liuf2 elasticsearch/

 

修改配置后，可以启动Elasticsearch：

$ sudo systemctl enable elasticsearch.service 
$ sudo systemctl restart elasticsearch.service

状态检查：

$ sudo systemctl status elasticsearch.service
