通过在弹性搜索配置中使用相同的集群名称来配置集群
您可能使用的默认 elasticsearch.yml 在开始时有这些设置,如下所示:
################################### Cluster ###################################
# Cluster name identifies your cluster for auto-discovery. If you're running
# multiple clusters on the same network, make sure you're using unique names.
#
# cluster.name: elasticsearch
#################################### Node #####################################
# Node names are generated dynamically on startup, so you're relieved
# from configuring them manually. You can tie this node to a specific name:
#
# node.name: "Franz Kafka"
这里你需要配置一个唯一的
cluster.name: "MainCluster"
并且对于每台机器和/或实例都有不同的唯一性
node.name: "LocalMachine1"
您现在需要将此elasticsearch.yml 复制到另一台机器(在同一个网络中),或复制到与elasticsearch_2.yml 相同的地方编辑它:
node.name: "LocalMachine2"
您的集群已准备就绪
如果没有配置 elastiscsearch 将使用一个随机的 Marvel 字符(根据文档为 3000 个),所以不要更改 node.name 也应该可以
为了让两个节点在同一台机器上运行,
您必须进行配置,例如elasticsearch_2.yml 复制,具有上述更改。
此外,您必须拥有数据和日志路径的副本
例如(自制特定路径:)
cp -r /usr/local/var/elasticsearch /usr/local/var/elasticsearch_2
cp -r /usr/local/var/log/elasticsearch /usr/local/var/log/elasticsearch_2
可能看起来像
#################################### Paths ####################################
# Path to directory containing configuration (this file and logging.yml):
#
# path.conf: /path/to/conf
# Path to directory where to store index data allocated for this node.
#
path.data: /usr/local/var/elasticsearch_2/
#
# Can optionally include more than one location, causing data to be striped across
# the locations (a la RAID 0) on a file level, favouring locations with most free
# space on creation. For example:
#
# path.data: /path/to/data1,/path/to/data2
# Path to temporary files:
#
# path.work: /path/to/work
# Path to log files:
#
path.logs: /usr/local/var/log/elasticsearch_2/
确保您没有在 localhost 环回设备上运行 elasicsearch
127.0.0.1
如果不是,只需将其注释掉(自制软件会以这种方式进行修补)
############################## Network And HTTP ###############################
# Elasticsearch, by default, binds itself to the 0.0.0.0 address, and listens
# on port [9200-9300] for HTTP traffic and on port [9300-9400] for node-to-node
# communication. (the range means that if the port is busy, it will automatically
# try the next port).
# Set the bind address specifically (IPv4 or IPv6):
#
# network.bind_host: 192.168.0.1
# Set the address other nodes will use to communicate with this node. If not
# set, it is automatically derived. It must point to an actual IP address.
#
# network.publish_host: 192.168.0.1
# Set both 'bind_host' and 'publish_host':
#
# network.host: 127.0.0.1
现在你可以像这样开始弹性搜索了:
bin/elasticsearch -D es.config=/usr/local/Cellar/elasticsearch/1.0.0.RC1/config/elasticsearch.yml
对于第一个节点和master(因为先启动)
然后
bin/elasticsearch -D es.config=/usr/local/Cellar/elasticsearch/1.0.0.RC1/config/elasticsearch_2.yml
现在你应该有 2 个节点在运行
