1. max file descriptors [4096] for elasticsearch process likely too low, increase to at least [65536]

* hard nofile 131072
* soft nproc 2048
* hard nproc 4096

2. max number of threads [1024] for user [lish] likely too low, increase to at least [2048]

vi /etc/security/limits.d/90-nproc.conf 

// 添加如下内容：
* soft nproc 2048

3. max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144]

vi /etc/sysctl.conf 

// 添加下面配置：

4. 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

vi ./config/elasticsearch.yml
// 放开注释
cluster.initial_master_nodes: ["node-1"]
