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Lucene
cat <<EOF>> /etc/security/limits.conf elasticsearch - nofile 65535 EOF # 在/etc/default/elasticsearch中修改: MAX_OPEN_FILES=65535
Virtual memory
cat <<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 curl localhost:9200/_nodes/process?pretty
