1.ES安装

1.1 资源规划

硬件资源为3台虚拟机，配置如下：

hostname

ip

cpu

内存

磁盘

操作系统

m162p201

192.168.162.201

2

8G

500G

CentOS Linux release 7.7.1908 (Core)

m162p201

192.168.162.201

2

8G

500G

CentOS Linux release 7.7.1908 (Core)

m162p201

192.168.162.201

2

8G

500G

CentOS Linux release 7.7.1908 (Core)

上述硬件配置将按如下命名规划：

hostname

ip

cluster

node

用户

seed_hosts

master_nodes

m162p201

192.168.162.201

es162

node201

elastic

T

m162p201

192.168.162.201

es162

node202

elastic

m162p201

192.168.162.201

es162

node203

elastic

1.2 安装软件

elasticsearch将安装在用户elastic下。创建用户脚本并上传软件：

代码语言：javascript复制
//创建一个elastic用户用以运行elasticsearch
useradd elastic
passwd elastic

//sftp上传到 /home/elastic
ls 
-rw-r--r-- 1 elastic elastic 327143992 Jul 23 20:23 elasticsearch-7.13.4-linux-x86_64.tar.gz
-rw-r--r-- 1 elastic elastic 306413260 Jul 23 20:23 kibana-7.13.4-linux-x86_64.tar.gz

//解压
tar -zxvf elasticsearch-7.13.4-linux-x86_64.tar.gz
tar -zxvf kibana-7.13.4-linux-x86_64.tar.gz

按上述操作，分别在以上3个节点中执行。 为了便于我们后续扩容，在真实场景中，可能存在一个机器部署多个节点的情况，那么我们可以使用软链接：

代码语言：javascript复制
mv elasticsearch-7.13.4  elasticsearch-7.13.4-node201
ln -s /home/elastic/elasticsearch-7.13.4-node201 /home/elastic/node201

这样后续我们就可以通过这个软链接方便的访问了。当然，如果生产环境，data目录可能也需要根据磁盘情况来重新规划，本文中的虚拟环境暂不考虑了。

1.3 检查句柄数

检查句柄数,如果过低，在/etc/security/limits.conf增加如下内容：

代码语言：javascript复制
elastic  soft nproc 16384
elastic  hard nproc 16384
elastic  soft nofile 65535
elastic  hard nofile 65536

或者一劳永逸的改为：

代码语言：javascript复制
* soft nproc 10000 
* hard nproc 10000
* soft nofile 1048576
* hard nofile 1048576

之后通过 ulimited -a 进行检查:

代码语言：javascript复制
[elastic@m162p201 config]$ ulimit -a
core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0
file size               (blocks, -f) unlimited
pending signals                 (-i) 31850
max locked memory       (kbytes, -l) 64
max memory size         (kbytes, -m) unlimited
open files                      (-n) 1048576
pipe size            (512 bytes, -p) 8
POSIX message queues     (bytes, -q) 819200
real-time priority              (-r) 0
stack size              (kbytes, -s) 8192
cpu time               (seconds, -t) unlimited
max user processes              (-u) 10000
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited

open files 即是文件句柄数。

1.4 调整vm.max_map_count

如果vm.max_map_count值过低，会造成elasticsearch启动之后会自动关闭并报错。 调整方式如下: 解决办法，修改：

代码语言：javascript复制
 vim /etc/sysctl.conf

末尾增加：

代码语言：javascript复制
vm.max_map_count=262144

之后执行：

代码语言：javascript复制
 sysctl -p

这样该配置项就会永久生效了。

1.5 jvm配置

如果不配置elastic用户的jvm参数，那么elasticsearch在启动的时候将会用elastcsearch自带的jdk启动，elasticsearch7.13.4 自带的jdk是 OpenJDk 16。我们可以切换到hotspot的1.8版本上来，这也是elasticsearch7.13所支持的最低版本。 修改.bash_profile:

代码语言：javascript复制
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/.local/bin:$HOME/bin

export PATH
#新增jvm参数
JAVA_HOME=/usr/java/jdk1.8.0_231-amd64
ES_JAVA_HOME=/usr/java/jdk1.8.0_231-amd64
export JAVA_HOME ES_JAVA_HOME
export PATH=.:$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

之后运行：

代码语言：javascript复制
source ./bash_profile

让这个配置生效。这样我们就能启动elasticsearch了。

# ======================== 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

# By default Elasticsearch listens for HTTP traffic on the first free port it
# finds starting at 9200. Set a specific HTTP port here:

http.port: 9200
#
# For more information, consult the network module documentation.

1.6 jvm配置

elasticsearch官方不建议修改jvm.options文件，而是在jvm.options.d中进行修改。我们在这个文件夹中建一个新的jvm.options文件，添加需要的java配置。

代码语言：javascript复制
-Xms2g
-Xmx2g

这是elasticsearch的堆内存配置，对于生产环境可以结合系统的资源情况酌情分配。

个人感觉新版本的kibana非常强大，后续专门在进行详细配置和使用说明。

node.js apache ElasticsearchService jvm es
