ElasticSearch部署文档(Ubuntu 14.04)

安装java

sudo add-apt-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java8-installer sudo apt-get install oracle-java8-set-default

安装ElasticSearch

wget -qO - https://packages.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add - echo "deb http://packages.elastic.co/elasticsearch/1.6/debian stable main" | sudo tee -a /etc/apt/sources.list sudo apt-get update sudo apt-get install elasticsearch sudo update-rc.d elasticsearch defaults 95 10

ElasticSearch各个目录说明

type description location home Home of elasticsearch installation /usr/share/elasticsearch bin Binary scripts including elasticsearch to start a node /usr/share/elasticsearch/bin conf Configuration files elasticsearch.yml and logging.yml /etc/elasticsearch conf Environment variables including heap size,file descriptors /etc/default/elasticsearch data The location of the data files /var/lib/elasticsearch/ logs Log files location /var/log/elasticsearch plugins Plugin files location /usr/share/elasticsearch/plugins

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.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

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: 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"]

启动

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
