3
tar -zxvf elasticsearch-xxxx.tar.gz -C /usr/local/elastic

tar -zxvf kibana-xxxx.tar.gz -C /usr/local/elastic

修改安装目录的所有者

1
chown -R elastic:elastic /usr/local/elastic

预先解决可能会遇到的问题

启动问题

问题一:max file descriptors [4096] for elasticsearch process likely too low, increase to at least [65536]
问题二:max number of threads [1024] for user [lish] likely too low, increase to at least [2048]

需要服务器增大文件、线程等的限制数

解决:修改切换到root用户修改配置limits.conf 添加下面两行
命令:vi /etc/security/limits.conf

1
2
3
4
*	hard	nofile	65536
* soft nofile 65536
* hard nproc 4096
* soft nproc 4096

问题三:max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144]
解决:切换到root用户修改配置sysctl.conf
vi /etc/sysctl.conf
添加下面配置:

1
vm.max_map_count=655360

并执行命令:

1
sysctl -p

调整内存

配置elasticsearch的运行堆大小,默认是1g,如果是学习用可调小,如果是生成用可根据资源情况调大。注意:最大、最小堆大小需相同

################################################################
## IMPORTANT: JVM heap size
################################################################
##
## You should always set the min and max JVM heap
## size to the same value. For example, to set
## the heap to 4 GB, set:
##
## -Xms4g
## -Xmx4g
##
## See https://www.elastic.co/guide/en/elasticsearch/reference/current/heap-size.html
## for more information
##
################################################################

# Xms represents the initial size of total heap space
# Xmx represents the maximum size of total heap space

-Xms256m
-Xmx256m

启动elasticsearch

配置调整

1
vi /usr/local/elastic/elasticsearch-xxx/config/jvm.options

设置3个点:

​ node.name: node-1 # 1 设置节点名称

​ network.host: 0.0.0.0 # 2 设置网络地址绑定

​ cluster.initial_master_nodes: [“node-1”] # 3 设置初始主节点

# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
# Before you set out to tweak and tune the configuration, make sure you
# understand what are you trying to accomplish and the consequences.
#
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
#
# Please consult the documentation for further information on configuration options:
# https://www.elastic.co/guide/en/elasticsearch/reference/index.html
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
#cluster.name: my-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: node-1 # 1 设置节点名称
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
#path.data: /path/to/data
#
# Path to log files:
#
#path.logs: /path/to/logs
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
#bootstrap.memory_lock: true
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
network.host: 0.0.0.0 # 2 设置网络地址绑定
#
# Set a custom port for HTTP:
#
#http.port: 9200
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when this node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
#discovery.seed_hosts: ["host1", "host2"]
#
# Bootstrap the cluster using an initial set of master-eligible nodes:
#
cluster.initial_master_nodes: ["node-1"] # 3 设置初始主节点
#
# For more information, consult the discovery and cluster formation module documentation.
#
# ---------------------------------- Gateway -----------------------------------
#
# Block initial recovery after a full cluster restart until N nodes are started:
#
#gateway.recover_after_nodes: 3
#
# For more information, consult the gateway module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Require explicit names when deleting indices:
#
#action.destructive_requires_name: true

/usr/local/elastic/elasticsearch-xxx/bin/elasticsearch -d

访问:

curl http://localhost:9200

浏览器访问:http://192.168.1.168:9200

启动Kibana

配置kibana

1
vi /usr/local/elastic/kibana-xxx/config/kibana.yml

配置kibana地址绑定

server.host: 0.0.0.0 # 1 设置网络地址绑定

如果kibana要访问的elasticsearch 和它不在一台机器上,则需要配置elasticsearch 的访问地址:

elasticsearch.hosts: [“http://localhost:9200"]

如果开启了安全认证,则需要配置访问elasticsearch的用户密码:

elasticsearch.username: “user”
elasticsearch.password: “pass”
