0、 服务器版本信息
Red Hat 4.8.5-44
CentOS Linux release 7.9.2009 (Core)
java version "1.8.0_281"
Docker version 20.10.6, build 370c289
1、ES部署
1.1 拉取docker镜像
docker pull elasticsearch:7.10.1
拉取成功的镜像,可以使用如下命令查看:
docker images
注:上图2年之前表示该elasticsearch的7.10.1镜像版本是2年前制作的。
1.2 创建es挂载目录
mkdir data
cd /data
mkdir elasticsearch
cd /data/elasticsearch
1.3 桥接网络节点配置
ES集群安装要求桥接网络和一定的vm配置,执行./network.sh
sysctl -w vm.max_map_count=262144
docker network ls
docker network create --driver bridge --subnet=172.18.12.0/16 --gateway=172.18.0.1 esnet
1.4 解压es证书配置文件
下载链接见:https://download.csdn.net/download/qq_33034733/88137295
tar -zxvf es-cfg.tar.gz cfg
1.5 创建ES主节点实例
给master.sh加执行权限:chmod u+x master.sh
执行./master.sh 直接创建2个主节点,
for port in $(seq 1 2); \
do \
mkdir -p /data/elasticsearch/master-${port}/config
cp -rf /data/elasticsearch/cfg/* /data/elasticsearch/master-${port}/config
mkdir -p /data/elasticsearch/master-${port}/data
mkdir -p /data/elasticsearch/master-${port}/logs
mkdir -p /data/elasticsearch/master-${port}/plugins
chmod -R 777 /data/elasticsearch/master-${port}
cat << EOF > /data/elasticsearch/master-${port}/config/elasticsearch.yml
cluster.name: imes-es #集群的名称,同一个集群该值必须设置成相同的
node.name: es-master-${port} #该节点的名字
node.master: true #该节点有机会成为master节点
node.data: false #该节点可以存储数据

discovery.seed_hosts: ["172.18.12.91:9301","172.18.12.92:9302"]
cluster.initial_master_nodes: ["es-master-1"] #新集群初始时的候选主节点,es7的新增配置
EOF
docker run --name es-master-${port} \

1.6 创建ES从节点实例
给slave.sh加执行权限:chmod u+x slave.sh文章来源:https://www.toymoban.com/news/detail-498276.html
然后执行./slave.sh 直接创建3个从节点的实例文章来源地址https://www.toymoban.com/news/detail-498276.html

mkdir -p /data/elasticsearch/node-${port}/config
