配置
# 在/etc/default/elasticsearch中修改：
ES_HEAP_SIZE=4g #不要超过32g，如果整台机器只部署ES，一半内存用于Java heap，另一半给Lucenecat <<EOF>> /etc/security/limits.conf
elasticsearch - nofile 65535
EOF
# 在/etc/default/elasticsearch中修改：
MAX_OPEN_FILES=65535cat <<EOF>> /etc/sysctl.conf
vm.max_map_count=262144
EOF
sysctl -p# 在/etc/elasticsearch/elasticsearch.yml中修改：
bootstrap.mlockall: true
# 在/etc/default/elasticsearch中修改：
MAX_LOCKED_MEMORY=unlimited在/etc/elasticsearch/elasticsearch.yml中修改：
# 集群名称，同一集群，名称要设置相同
cluster.name: elasticsearch_production
# 节点名称
node.name: elasticsearch_001_data
# 数据路径，可配置多个，英文逗号分开，注意目录的权限，保证elasticsearch用户可写
path.data: /path/to/data1,/path/to/data2
# 日志路径，注意目录的权限，保证elasticsearch用户可写
path.logs: /path/to/logs
# 插件路径
path.plugins: /path/to/plugins
# 该属性是为了形成一个集群，有主节点资格并互相连接的节点的最小数目
# (number of master-eligible nodes / 2) + 1。 下面的值是在3个有主节点资格的情况下设定
# 因为节点数，以后可以增加，或者减少，故该配置可以动态修改
discovery.zen.minimum_master_nodes: 2
# 恢复控制
gateway.recover_after_nodes: 2
gateway.expected_nodes: 3
gateway.recover_after_time: 5m
#关闭多播，用单播。并指定至少一个能接受单播的主机
discovery.zen.ping.multicast.enabled: false
discovery.zen.ping.unicast.hosts: ["192.168.2.1:9300", "192.168.2.2:9300", "192.168.2.3:9300"]sudo /etc/init.d/elasticsearch start
# 验证上面一些配置是否配置成功
