1. 基础环境准备

3台服务器，每个上面启动1个es实例，组成3个节点的es集群

1.1 linux服务器上创建用户es

在每个服务器上创建es用户，用于启动elasticsearch实例

useradd es
passwd es

输入es的密码

1.2 创建es安装包的目录

• es安装包目录

mkdir /home/data6/es

将es的安装包 elasticsearch-7.6.1-linux-x86_64.tar.gz 上传至每个服务器的上述路径，解压 tar -zxvf    elasticsearch-7.6.1-linux-x86_64.tar.gz

/home/data6/es目录下，会生成 elasticsearch-7.6.1 文件夹。

将上述文件夹的所有者，都改成es用户，执行命令  ：

chown es:es -R /home/data6/es

 

• es数据存储目录

这里创建两个数据目录，es配置文件中用到

mkdir /home/data5/es/data

mkdir /home/data6/es/data

• es日志目录，es配置文件中用到

mkdir /home/data6/es/logs

 

1.3 修改服务器配置

• 修改/etcsysctl.conf文件

vim /etc/sysctl.conf
fs.file-max=65536
vm.max_map_count=262144

使用sysctl -p使条件生效

 

• 修改 /etc/security/limits.conf

vim /etc/security/limits.conf

添加如下配置
* soft nofile 65536
* hard nofile 65536
* soft nproc 65536
* hard nproc 65536
* soft memlock unlimited
* hard memlock unlimited

 

终端登出当前用户，让上述配置生效。

 

2. 修改es节点的配置文件elasticsearch.yml

修改每个es节点的配置文件，使之组成一个es集群，这里使用集群的最简单化配置，其余的优化配置，请参考官网的配置文档。

• node-1节点

# ---------------------------------- Cluster -----------------------------------
cluster.name: my-es-cluster
# ------------------------------------ Node ------------------------------------
node.name: node-1
# ----------------------------------- Paths ------------------------------------
path.data: /home/data5/es/data,/home/data6/es/data
path.logs: /home/data6/es/logs
#
# ---------------------------------- Network -----------------------------------
network.host: myhost132
http.port: 9200
# --------------------------------- Discovery ----------------------------------
discovery.seed_hosts: ["myhost132", "myhost133", "myhost134"]
cluster.initial_master_nodes: ["node-1", "node-2", "node-3"]

# ---------------------------------- Cluster Other Configuration -----------------------------------
node.master: true
node.data: true

 

• node-2节点

# ---------------------------------- Cluster -----------------------------------
cluster.name: my-es-cluster
# ------------------------------------ Node ------------------------------------
node.name: node-2
# ----------------------------------- Paths ------------------------------------
path.data: /home/data5/es/data,/home/data6/es/data
path.logs: /home/data6/es/logs
#
# ---------------------------------- Network -----------------------------------
network.host: myhost133
http.port: 9200
# --------------------------------- Discovery ----------------------------------
discovery.seed_hosts: ["myhost132", "myhost133", "myhost134"]
cluster.initial_master_nodes: ["node-1", "node-2", "node-3"]

# ---------------------------------- Cluster Other Configuration -----------------------------------
node.master: true
node.data: true

 

• node-3节点

# ---------------------------------- Cluster -----------------------------------
cluster.name: my-es-cluster
# ------------------------------------ Node ------------------------------------
node.name: node-3
# ----------------------------------- Paths ------------------------------------
path.data: /home/data5/es/data,/home/data6/es/data
path.logs: /home/data6/es/logs
#
# ---------------------------------- Network -----------------------------------
network.host: myhost134
http.port: 9200
# --------------------------------- Discovery ----------------------------------
discovery.seed_hosts: ["myhost132", "myhost133", "myhost134"]
cluster.initial_master_nodes: ["node-1", "node-2", "node-3"]

# ---------------------------------- Cluster Other Configuration -----------------------------------
node.master: true
node.data: true

 

3. 启动es集群

3.1 逐个启动es实例

依次登陆到每个服务器上，启动es实例

切换到es安装包的目录   cd /home/data6/es

执行启动命令：

./elasticsearch-7.6.1/bin/elasticsearch -d -p pid

3.2 验证es集群是否启动成功

curl -l http://myhost132:9200
curl -l http://myhost133:9200
curl -l http://myhost134:9200

 

4. 依次停止es实例

执行以下命令

cd /home/data6/es
pkill -F pid
