Asuicao2024-05-14 12:55

配置文件位置:

复制代码

 程序配置文件：/etc/elasticsearch/elasticsearch.yml

 jvm配置文件：/etc/elasticsearch/jvm.options

1. 确认基础环境

确认主机limit相关参数

bash 复制代码

grep vm.max_map_count /etc/sysctl.conf && sed -i "s@vm.max_map_count.*@vm.max_map_count=655360@g" /etc/sysctl.conf || echo 'vm.max_map_count=655360' >>/etc/sysctl.conf
sysctl -p

确认主机无其他ElasticSearch软件包

bash 复制代码

rpm -qa | grep elasticsearch >/dev/null && echo exists || echo yes#执行此命令输出为yes即可

2. 使用YUM源进行安装

bash 复制代码

yum install jdk1.8.0_131 wget -y
wget http://foreman.lilinlin.science:8080/x86_64/elk/elasticsearch-6.8.7.rpm
yum localinstall elasticsearch-6.8.7.rpm -y
rm -f elasticsearch-6.8.7.rpm

3. 修改配置

以下命令修改ip地址为安装es主机的内网ip

bash 复制代码

sed -i "s@^#network.host.*@network.host: 192.168.1.200@g" /etc/elasticsearch/elasticsearch.yml

4.启动

bash 复制代码

systemctl start elasticsearch

5. 安装IK分词

bash 复制代码

cd /tmp/

wget https://web.chinamcloud.com/k8s/ik/elasticsearch-analysis-ik-6.8.7.zip

/usr/share/elasticsearch/bin/elasticsearch-plugin install file:///tmp/elasticsearch-analysis-ik-6.8.7.zip

6.重动服务

bash 复制代码

systemctl restart elasticsearch

systemctl enable elasticsearch

7.检测

以下命令涉及ip换成自己es节点内网ip

bash 复制代码

curl http://192.168.1.200:9200/_cat/plugins | grep "analysis-ik 6.8.7" &>/dev/null && echo 'success' || echo 'fail'

|---|
| |

上面命令输出success则为成功，输出fail则失败，需要检查日志

8.暴露服务

在master上执行

bash 复制代码

cat > elasticsearch_service.yaml <<EOF

apiVersion: v1

kind: Service

metadata:

  annotations:

    field.cattle.io/ipAddresses: '["192.168.1.200"]'#改ip为自己环境es ip，切勿删除或新增内容

  name: elasticsearch

  namespace: server

spec:

  clusterIP: None

  ports:

  - name: elasticsearch

    port: 9200

    protocol: TCP

    targetPort: 9200

  sessionAffinity: None

  type: ClusterIP

EOF



kubectl apply -f elasticsearch_service.yaml
