这里准备三台服务器如下:
IP地址主机名节点名192.168.225.65linux1node-1192.168.225.66linux2node-2192.168.225.67linux3node-3
2、准备elasticsearch安装环境
(1)编辑/etc/hosts#xff08;三台服务器都执行#xff09;
vim /etc/hosts
添加如下内…1、准备三台服务器
这里准备三台服务器如下:
IP地址主机名节点名192.168.225.65linux1node-1192.168.225.66linux2node-2192.168.225.67linux3node-3
2、准备elasticsearch安装环境
(1)编辑/etc/hosts三台服务器都执行
vim /etc/hosts
添加如下内容
192.168.225.65 linux1
192.168.225.66 linux2
192.168.225.67 linux32编辑/etc/hostname (三台服务器都执行)
在192.168.225.65上修改
echo linux1 /etc/hostname
在192.168.225.66上修改
echo linux2 /etc/hostname
在192.168.225.67上修改
echo linux3 /etc/hostname3修改系统参数 三台服务器都执行
vim /etc/security/limits.conf
修改内容如下
* soft nofile 65536
* hard nofile 131072
* soft nproc 4096
* hard nproc 4096 vim /etc/sysctl.conf
修改内容如下
vm.max_map_count 262145
保存退出刷新配置文件
sysctl -p 4上传elasticsearch安装包和创建安装用户三台服务器都执行 elasticsearch-7.8.1下载地址
这里是将elasticsearch安装包elasticsearch-7.8.1-linux-x86_64.tar.gz上传到/opt目录下
cd /opt
tar -zxvf elasticsearch-7.8.1-linux-x86_64.tar.gz
mv elasticsearch-7.8.1 elasticsearch7.8
useradd jamysong
chown -R jamysong:jamysong /opt/elasticsearch7.8注意做完以上四步重启下三台服务器
3、安装elasticsearch
(1) 编辑elasticsearch配置文件
vim /opt/elasticsearch7.8/cong/elasticsearch.yaml
node1的配置文件
cluster.name: cluster-jamysong
node.name: node-1
network.host: linux1
node.master: true
node.data: true
http.port: 9200
http.cors.allow-origin: *
http.cors.enabled: true
http.max_content_length: 200mb
cluster.initial_master_nodes: [node-1]
discovery.seed_hosts: [linux1:9300, linux2:9300,linux3:9300]
gateway.recover_after_nodes: 2
network.tcp.keep_alive: true
network.tcp.no_delay: true
transport.tcp.compress: true
cluster.routing.allocation.cluster_concurrent_rebalance: 16
cluster.routing.allocation.node_concurrent_recoveries: 16
cluster.routing.allocation.node_initial_primaries_recoveries: 16node2的配置文件
cluster.name: cluster-jamysong
node.name: node-2
network.host: linux2
node.master: true
node.data: true
http.port: 9200
http.cors.allow-origin: *
http.cors.enabled: true
http.max_content_length: 200mb
cluster.initial_master_nodes: [node-1]
discovery.seed_hosts: [linux1:9300, linux2:9300,linux3:9300]
gateway.recover_after_nodes: 2
network.tcp.keep_alive: true
network.tcp.no_delay: true
transport.tcp.compress: true
cluster.routing.allocation.cluster_concurrent_rebalance: 16
cluster.routing.allocation.node_concurrent_recoveries: 16
cluster.routing.allocation.node_initial_primaries_recoveries: 16node3的配置文件
cluster.name: cluster-jamysong
node.name: node-3
network.host: linux3
node.master: true
node.data: true
http.port: 9200
http.cors.allow-origin: *
http.cors.enabled: true
http.max_content_length: 200mb
cluster.initial_master_nodes: [node-1]
discovery.seed_hosts: [linux1:9300, linux2:9300,linux3:9300]
gateway.recover_after_nodes: 2
network.tcp.keep_alive: true
network.tcp.no_delay: true
transport.tcp.compress: true
cluster.routing.allocation.cluster_concurrent_rebalance: 16
cluster.routing.allocation.node_concurrent_recoveries: 16
cluster.routing.allocation.node_initial_primaries_recoveries: 16(2)启动elasticsearch
现在直接去启动每台服务器上面的elasticsearch
su jamysong
cd /opt/elasticsearch7.8/bin
./elasticsearch注意elasticsearch是不允许root用户启动的这里使用上面创建的安装用户jamysong启动 !
查看启动日志如下表示启动成功
(3)检测elasticsearch集群
这里可以直接访问浏览器来检测一下集群是否搭建成功这里可以看到node-1是主节点node-2和node-3是从节点
