es集群安装及优化

es主节点 192.168.23.100 es节点 192.168.23.101 192.168.23.102

1.安装主节点

1.去官网下载es的yum包 官网下载地址 https://www.elastic.co/cn/downloads/elasticsearch 根据自己的需要下载对应的包

2.下载好之后把所有的包都传到从节点上，安装 [root@localhost ~]# ansible all -m copy -a 'src=/root/elasticsearch-8.11.3-x86_64.rpm dest=/root/elasticsearch-8.11.3-x86_64.rpm' 192.168.23.102 | CHANGED => { "ansible_facts": { "discovered_interpreter_python": "/usr/bin/python" }, "changed": true, "checksum": "64c9029f99fa4beeabae1a36d1a88b8bf44982cf", "dest": "/root/elasticsearch-8.11.3-x86_64.rpm", "gid": 0, "group": "root", "md5sum": "d4b85a836646cd0b8c1d87848bf2e77c", "mode": "0644", "owner": "root", "size": 630669510, "src": "/root/.ansible/tmp/ansible-tmp-1704551077.26-16135-196050427416681/source", "state": "file", "uid": 0 } 192.168.23.101 | CHANGED => { "ansible_facts": { "discovered_interpreter_python": "/usr/bin/python" }, "changed": true, "checksum": "64c9029f99fa4beeabae1a36d1a88b8bf44982cf", "dest": "/root/elasticsearch-8.11.3-x86_64.rpm", "gid": 0, "group": "root", "md5sum": "d4b85a836646cd0b8c1d87848bf2e77c", "mode": "0644", "owner": "root", "size": 630669510, "src": "/root/.ansible/tmp/ansible-tmp-1704551077.26-16133-148347610662829/source", "state": "file", "uid": 0 } [root@localhost ~]# ansible all -m shell -a 'ls /root/' 192.168.23.102 | CHANGED | rc=0 >> anaconda-ks.cfg elasticsearch-8.11.3-x86_64.rpm 192.168.23.101 | CHANGED | rc=0 >> anaconda-ks.cfg elasticsearch-8.11.3-x86_64.rpm [root@localhost ~]# ansible all -m shell -a 'yum localinstall /root/elasticsearch-8.11.3-x86_64.rpm -y' [WARNING]: Consider using the yum module rather than running 'yum'. If you need to use command because yum is insufficient you can add 'warn: false' to this command task or set 'command_warnings=False' in ansible.cfg to get rid of this message. 192.168.23.101 | CHANGED | rc=0 >> Loaded plugins: fastestmirror Examining /root/elasticsearch-8.11.3-x86_64.rpm: elasticsearch-8.11.3-1.x86_64 Marking /root/elasticsearch-8.11.3-x86_64.rpm to be installed Resolving Dependencies --> Running transaction check ---> Package elasticsearch.x86_64 0:8.11.3-1 will be installed --> Finished Dependency Resolution Dependencies Resolved ================================================================================ Package Arch Version Repository Size ================================================================================ Installing: elasticsearch x86_64 8.11.3-1 /elasticsearch-8.11.3-x86_64 1.2 G Transaction Summary ================================================================================ Install 1 Package Total size: 1.2 G 3.更改主配置文件 [root@localhost ~]# grep -Ev "^#|^$" /etc/elasticsearch/elasticsearch.yml cluster.name: ELK cluster #集群名字，每个节点一样 node.name: {{ ansible_hostname }} #每个机器的主机名 path.data: /var/lib/elasticsearch path.logs: /var/log/elasticsearch network.host: 0.0.0.0 # 通讯地址，设置为本机ip或者0.0.0.0，让所有机器都可以访问 discovery.seed_hosts: ["192.168.23.100", "192.168.23.101","192.168.23.102"] #每个节点相同 cluster.initial_master_nodes: ["192.168.23.100"] #此为选举主节点，如果写一个就默认那一个是主节点，如果写多个，让他们自己去竞争那个是节点 xpack.security.enabled: false #关闭安全认证 xpack.security.enrollment.enabled: true xpack.security.http.ssl: enabled: true keystore.path: certs/http.p12 xpack.security.transport.ssl: enabled: true verification_mode: certificate keystore.path: certs/transport.p12 truststore.path: certs/transport.p12 http.host: 0.0.0.0

4.写yml吧配置文件传送到 其他节点

[root@es ~]# cat 1.yml --- [root@es ~]# cat 1.yml [root@es ~]# cat 1.yml --- - name: copy es hosts: xp tasks: - name: copy es template: src: /etc/elasticsearch/elasticsearch.yml dest: /etc/elasticsearch/elasticsearch.yml notify: restart es - name: restart es service: name: elasticsearch enabled: yes handlers: - name: restart es service: name: elasticsearch state: restarted 5.运行playbook [root@es ~]# ansible-playbook 1.yml PLAY [copy es] *************************************************************************************************************************************************************************************************** TASK [Gathering Facts] ******************************************************************************************************************************************************************************************* ok: [192.168.23.101] ok: [192.168.23.102] TASK [copy es] *************************************************************************************************************************************************************************************************** ok: [192.168.23.102] ok: [192.168.23.101] TASK [restart es] ************************************************************************************************************************************************************************************************ changed: [192.168.23.102] changed: [192.168.23.101] PLAY RECAP ******************************************************************************************************************************************************************************************************* 192.168.23.101 : ok=3 changed=1 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0 192.168.23.102 : ok=3 changed=1 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0 此时在访问主节点上的9200端口
