【非标】es屏蔽中心扩容协调节点

准备信息

sellout ES集群 扩容4个协调节点.



# 4个新节点
172.21.56.207
172.21.56.208
172.21.56.209
172.21.56.210

检查数据盘挂载点

数据盘需要挂载在/data下，文件格式为xfs，做LVM

mount -a

2. 传包

创建es相关目录

mkdir -p /data/elasticsearch/data
mkdir -p /data/elasticsearch/log
mkdir -p /data/elasticsearch/backup

4. rpm安装服务

# 安装es服务
rpm -i /data/elasticsearch-6.4.3.rpm
systemctl enable elasticsearch

# es 数据文件的权限
chown -R elasticsearch.elasticsearch /data/elasticsearch

# 备份原来的yml
mv /etc/elasticsearch/elasticsearch.yml /etc/elasticsearch/elasticsearch.yml_bak

# es yml 配置文件修改，4个节点对应的配置文件如下补充
vi /etc/elasticsearch/elasticsearch.yml

5. 由于ES643版本，不带jdk，需要修改为JAVA_HOME=/opt/jdk8

vim /etc/sysconfig/elasticsearch

# 找到注释掉的 JAVA_HOME后，修改为
JAVA_HOME=/opt/jdk8

6. 安装IK分词器

# 安装，直接y
/usr/share/elasticsearch/bin/elasticsearch-plugin install file:///data/elasticsearch-analysis-ik-6.4.3.zip

7. 修改jvm heap size

# 修改 jvm.options 中的jvm heap大小，主机内存是16G，该配置修改为 10G
vim /etc/elasticsearch/jvm.options
-Xms10g
-Xmx10g 

8. 启动es服务

# 
systemctl start elasticsearch

9. 安装es exporter

# 先检查，没有的话就安装
rpm -qa | grep elasticsearch_exporter

# 安装 es exporter
rpm -i /data/elasticsearch_exporter-1.3.0-1.el7.x86_64.rpm
sudo yum install elasticsearch_exporter-1.3.0-1.el7.x86_64

# 修改es exporter的default文件,将其中的localhost改为本机IP
vim /etc/default/elasticsearch_exporter

# 重启es exporter服务
systemctl restart elasticsearch_exporter

10. 检查ES集群状态

# 查看集群所有节点信息
curl http://172.21.56.207:9200/_cat/nodes?v


# 查看节点172.21.56.207 的es服务
curl http://172.21.56.207:9200

11. 对接监控

选择 裸资源。

注册完成后，等几分钟后在夜莺中验证下

如果能查询到9114的信息，说明注册成功，监控对接完成。

## 更新ES清单

协调节点es yml配置文件
