elasticsearch安装

　　安装包准备，将安装包上传到opt目录下，解压，文件夹重命名

tar -zxvf elasticsearch-x.x.x.tar.gz

mv elasticsearch-x.x.x es

　　设置内核参数

vi /etc/sysctl.conf

 增加以下参数

vm.max_map_count=655360

　执行以下命令确保配置生效。

　sysctl -p

　　设置资源参数

vi /etc/security/limits.conf

# 修改如下

*  soft    nproc   1024000
*  hard    nproc   1024000
*  soft    nofile  1024000
*  hard    nofile  1024000

　　设置用户资源参数

vi /etc/security/limits.d/20-nproc.conf

# 设置es用户参数

es    soft    nproc     65536

　　添加启动用户，设置权限

useradd es         #创建用户es

groupadd es        #创建组es

usermod es -g es  #将用户添加到组

题外话：

要是再Ubuntu下添加用户、组，则使用如下命令：

useradd -d "/home/es" -m -s "/bin/bash" es

该命令会创建用户和所属组

常用命令行选项：

• -d： 指定用户的主目录

• -m： 如果存在不再创建，但是此目录并不属于新创建用户；如果主目录不存在，则强制创建； -m和-d一块使用。

• -s： 指定用户登录时的shell版本

• -M： 不创建主目录

mkdir  -p  /opt/es/{data,logs} # 创建数据和日志目录

# 修改文件所有者

chown -R es:es /opt/es/

chown -R es:es /opt/es/

　　修改Elasticsearch的配置文件

vi  /opt/es/config/elasticsearch.yml

# ======================== 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: es-app
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: node-1
#
# 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: /opt/es/data
#
# Path to log files:
#
path.logs: /opt/es/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: 192.168.244.129
#
# Set a custom port for HTTP:
#
http.port: 9200
#

　　启动es

切换到es用户，到bin目录下启动es
su - es

cd /opt/es/bin

./elasticsearch

我这里没报错，直接在浏览器访问es

192.168.244.xx:9200

{
  "name": "node-1",
  "cluster_name": "es-app",
  "cluster_uuid": "-oZN4SydQCWq1XaKH_e7qw",
  "version": {
    "number": "6.8.8",
    "build_flavor": "default",
    "build_type": "tar",
    "build_hash": "2f4c224",
    "build_date": "2020-03-18T23:22:18.622755Z",

    "minimum_wire_compatibility_version": "5.6.0",
    "minimum_index_compatibility_version": "5.0.0"
  },
  "tagline": "You Know, for Search"
}

　　在版本7以后，启动可能会报如下错

　　解决办法，在配置文件中加入以下命令

xpack.ml.enabled: false

　　安装Kibana

　　将kibana-6.8.8-linux-x86_64上传至/usr/local/下，解压

tar -zxvf kibana-6.8.8-linux-x86_64.tar.gz

mv kibana-6.8.8-linux-x86_64 kibana

　　编辑kibana配置

vi /usr/local/kibana/config/kibana.yml

# Kibana is served by a back end server. This setting specifies the port to use.
#server.port: 5601

# Specifies the address to which the Kibana server will bind. IP addresses and host names are both valid values.
# The default is 'localhost', which usually means remote machines will not be able to connect.
# To allow connections from remote users, set this parameter to a non-loopback address.
server.host: "192.168.244.129"

# Enables you to specify a path to mount Kibana at if you are running behind a proxy.
# Use the `server.rewriteBasePath` setting to tell Kibana if it should remove the basePath
# from requests it receives, and to prevent a deprecation warning at startup.
# This setting cannot end in a slash.
#server.basePath: ""

# Specifies whether Kibana should rewrite requests that are prefixed with
# `server.basePath` or require that they are rewritten by your reverse proxy.
# This setting was effectively always `false` before Kibana 6.3 and will
# default to `true` starting in Kibana 7.0.
#server.rewriteBasePath: false

# The maximum payload size in bytes for incoming server requests.
#server.maxPayloadBytes: 1048576

# The Kibana server's name.  This is used for display purposes.
#server.name: "your-hostname"

# The URLs of the Elasticsearch instances to use for all your queries.
elasticsearch.hosts: ["http://192.168.244.129:9200"]

# When this setting's value is true Kibana uses the hostname specified in the server.host
# setting. When the value of this setting is false, Kibana uses the hostname of the host
# that connects to this Kibana instance.
#elasticsearch.preserveHost: true

# Kibana uses an index in Elasticsearch to store saved searches, visualizations and
# dashboards. Kibana creates a new index if the index doesn't already exist.
#kibana.index: ".kibana"

# The default application to load.

　　启动kibana

cd /usr/local/kibana/bin/

./kibana

浏览器地访问

http://192.168.244.xx:5601

看到如下界面即成功

 　　设置es开机自启动

创建es 的系统启动服务文件，进入到 cd /etc/init.d 目录；
cd /etc/init.d    　　【进入到目录】
vi elasticsearch 　　 【创建es系统启动服务文件】
编写启动脚本；
#!/bin/bash
#chkconfig: 345 63 37
#description: elasticsearch
#processname: elasticsearch

export ES_HOME=/opt/es/

case $1 in
        start)
                su - es<<!
                cd $ES_HOME
                ./bin/elasticsearch -d -p pid
                exit
!
                echo "elasticsearch is started"
                ;;
        stop)
                pid=`cat $ES_HOME/pid`
                kill -9 $pid
                echo "elasticsearch is stopped"
                ;;
        restart)
                pid=`cat $ES_HOME/pid`
                kill -9 $pid
                echo "elasticsearch is stopped"
                sleep 1
                su es<<!
                cd $ES_HOME
                ./bin/elasticsearch -d -p pid
                exit
!
                echo "elasticsearch is started"
        ;;
    *)
        echo "start|stop|restart"
        ;;  
esac
exit 0

保存退出
修改文件权限；
复制代码
chmod 777 elasticsearch
添加和删除服务并设置启动方式；
复制代码
chkconfig --add elasticsearch　　　　#【添加系统服务】
chkconfig --del elasticsearch　　　　#【删除系统服务】
若是在国产操作系统UOS或者Ubuntu上设置服务，可以使用
systemctl enable elasticsearch     #【添加服务】
systemctl disable elasticsearch    #【删除服务】
关闭和启动服务；
复制代码
service elasticsearch start　　　　　#【启动】
service elasticsearch stop　　　　　 #【停止】
systemctl start elasticsearch
systemctl stop elasticsearch
service elasticsearch restart　　   #【重启】
设置服务是否开机启动；
复制代码
chkconfig elasticsearch on　　　　　　#【开启】
chkconfig elasticsearch off　　   　 #【关闭】
________________________________________
验证是否已启动命令：
复制代码
ps -ef | grep elasticsearch    #【查看是否有es的进程】
结束进程命令用kill -9 进程ID；

　　设置kibana开机自启动

  cd /etc/init.d

  touch kibana

  chmod +x kibana

  vi kibana并输入以下内容:


#!/bin/bash

# chkconfig:   2345 98  02
# description:  kibana

KIBANA_HOME=/usr/local/kibana
case $1 in
        start) $KIBANA_HOME/bin/kibana &;;
        *) echo "kibana is start";;
esac

 　　如若是在Ubuntu上配置开机自启动，则可以仿照下面的方式

#!/bin/bash
### BEGIN INIT INFO
# Provides: kibana
# Required-Start:
# Required-Stop:
# Default-Start:  2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: start and stop kibana
# Description: kibana
### END INIT INFO

KB_HOME=/opt/software/kibana

case $1 in
        start)$KB_HOME/bin/kibana --allow-root &;;
        *) echo "kibana is start";;
esac

　　kibana和elasticsearch都是不能在root用户下启动的，所以在脚本加个参数“--allow-root”
