ElasticSearch部署文档(Ubuntu 14.04)

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

| data | The location of the data files | /var/lib/elasticsearch/ |

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 <> /etc/security/limits.conf
elasticsearch - nofile 65535
EOF

在/etc/default/elasticsearch中修改：

MAX_OPEN_FILES=65535
Virtual memory
cat <> /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
