安装ElasticSearch

cd /data/apps/es
#上传elasticsearch-7.4.2-linux-x86_64.tar.gz到此目录

tar -xzvf elasticsearch-7.4.2-linux-x86_64.tar.gz
cd elasticsearch-7.4.2/

#创建用户jerval
adduser jerval
passwd jerval

#授权文件夹
chown -R jerval /data

#创建ElasticSearch工作文件夹
mkdir -p /data/apps/es/data
mkdir -p /data/logs/es

su jerval

vim elasticsearch.yml
#修改：
path.data: /data/apps/es/data
path.logs: /data/logs/es
network.host: 0.0.0.0

#错误处理：
#[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65535]
su root
vim /etc/security/limits.conf

#在文件最后，增加如下配置：
jerval    hard     nofile     65536 
jerval    soft     nofile     65536
*         soft     nproc      4096
*         hard     nproc      4096

#[2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
su root
vim /etc/sysctl.conf
#在/etc/sysctl.conf文件最后添加一行
vm.max_map_count=655360

#添加完毕之后，执行命令：
sysctl -p

[3]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured
vim config/elasticsearch.yml
在#node.name: node-1下面添加一行：
node.name: node-1

#在#cluster.initial_master_nodes: ["node-1", "node-2"]下面添加一行：
cluster.initial_master_nodes: ["node-1"]

#启动ES
./bin/elasticsearch
