ElasticSearch启动报错，bootstrap checks failed

修改elasticsearch.yml配置文件，在Discovery栏下加上“cluster.initial_master_nodes: [“node-1”]”，重启elasticsearch即可。如下所示：

# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when this node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
#discovery.seed_hosts: ["host1", "host2"]
#
# Bootstrap the cluster using an initial set of master-eligible nodes:
#
cluster.initial_master_nodes: ["node-1"]

# Set the bind address to a specific IP (IPv4 or IPv6):
# 下面是本机ip
network.host: 192.168.1.113
#
# Set a custom port for HTTP:
# 下面是es通过rest http接口访问的端口号
http.port: 9200

后台启动

./bin/elasticsearch -d -p pid
