配置

ES_HEAP_SIZE

# 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Lucene

File Descriptors

cat <<EOF>> /etc/security/limits.confelasticsearch - nofile 65535EOF# 在/etc/default/elasticsearch中修改：MAX_OPEN_FILES=65535

Virtual memory

cat <<EOF>> /etc/sysctl.confvm.max_map_count=262144EOFsysctl -p

Memory Settings

# 在/etc/elasticsearch/elasticsearch.yml中修改：bootstrap.mlockall: true# 在/etc/default/elasticsearch中修改：MAX_LOCKED_MEMORY=unlimited

其他

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: 2gateway.expected_nodes: 3gateway.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"]

启动
