二:ES的伪集群部署

2.1 安装单机的ES集群

  1. mkdir -p /esdb
  2. mkdir -p /esdb/soft
  3. 将所有的软件传到/esdb/soft 软件下面
  4. chown esadmin:esadmin -R /esdb/

image_1et3s3k3uqlv7ah1n1b1ann10p113.png-96.4kB

  1. 配置jdk
  2. su - esadmin
  3. cd /esdb/
  4. tar zxvf soft/jdk-14.0.2_linux-x64_bin.tar.gz
  5. export LANG=en_US.UTF8
  6. cat >> ~/.bash_profile << EOF
  7. export JAVA_HOME=/esdb/jdk-14.0.2
  8. export PATH=/esdb/jdk-14.0.2/bin:$PATH
  9. export LANG=en_US.UTF8
  10. EOF
  11. source ~/.bash_profile
  12. java -version

image_1et3s7so845t50f1f8c1jopj9e1g.png-153.3kB


  1. mkdir -p /esdb/esapp/esapp9201
  2. mkdir -p /esdb/esapp/esapp9202
  3. mkdir -p /esdb/esapp/esapp9203
  4. mkdir -p /esdb/esdata/esdata9201
  5. mkdir -p /esdb/esdata/esdata9202
  6. mkdir -p /esdb/esdata/esdata9203
  7. mkdir -p /esdb/eslog/eslog9201
  8. mkdir -p /esdb/eslog/eslog9202
  9. mkdir -p /esdb/eslog/eslog9203

image_1et3sabgg1ehi401md7ukn3sc1t.png-142.8kB


  1. cd /esdb/soft
  2. tar -zxvf /esdb/soft/elasticsearch-7.9.0-linux-x86_64.tar.gz
  3. cp -ap /esdb/soft/elasticsearch-7.9.0/* /esdb/esapp/esapp9201/
  4. cp -ap /esdb/soft/elasticsearch-7.9.0/* /esdb/esapp/esapp9202/
  5. cp -ap /esdb/soft/elasticsearch-7.9.0/* /esdb/esapp/esapp9203/
