安装 elasticsearch

1、安装

# vim instll-es.sh
  mkdir /opt/es
  wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.9.2-linux-x86_64.tar.gz  -P /opt/es
  cd /opt/es
  tar xf elasticsearch-7.9.2-linux-x86_64.tar.gz
  ln -s /opt/es/elasticsearch-7.9.2 /opt/es/elasticsearch

2、系统优化

# echo "* soft nofile 65535
  * hard nofile 65535
  * soft nproc 65535
  * hard nproc 65535"  >> /etc/security/limits.conf

# echo "vm.max_map_count=655360" >>/etc/sysctl.conf
# sysctl -p

# vim /etc/profile
  export JAVA_HOME=/opt/es/elasticsearch/jdk
  export ES_HOME=/opt/es/elasticsearch
  export PATH=$ES_HOME/bin:$ES_HOME/jdk/bin:$PATH
# source /etc/profile

3、启动

# useradd es
# chown -R es /opt/es/elasticsearch
# su - es  
$ /opt/es/elasticsearch/bin/elasticsearch -d

4、rpm安装

# yum instll https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.4.3-x86_64.rpm

5、elasticsearch配置密码

1、修改配置文件
# vim  elasticsearch.yml
  node.name: node-1
  network.host: 0.0.0.0
  cluster.initial_master_nodes: ["node-1"]
  http.port: 9200
  transport.tcp.port: 9300
  http.cors.enabled: true
  http.cors.allow-origin: "*"
  http.cors.allow-headers: Authorization
  xpack.security.enabled: true
  xpack.security.transport.ssl.enabled: true

2、配置密码
# elasticsearch-setup-passwords interactive

3、修改密码
# curl -H "Content-Type:application/json" -XPOST -u elastic 'http://127.0.0.1:9200/_xpack/security/user/elastic/_password' -d '{ "password" : "123456" }'

4、验证
# curl -XGET --user elastic:123456 'http://127.0.0.1:9200'

 6、配置文件解析

cluster.name: gwrmt                    #集群名，唯一
node.name: gwrmt02-console             #节点名，唯一
node.master: true                      #是否是主节点
node.data: true                        #是否存储数据

path.data: /mnt/data/es/data           #数据路径，可多个，逗号分隔
path.logs: /mnt/data/logs/es/log       #日志路径

bootstrap.memory_lock: false           #锁内存，是否用swap
bootstrap.system_call_filter: false    #是否使用系统调用seccomp

network.host: 192.168.1.36             #绑定ip
http.port: 9200                        #端口
transport.port: 9300                   #集群通信端口

discovery.seed_hosts: ["192.168.1.38","192.168.1.36"]                 #集群节点列表，ip+端口，不写默认9300
cluster.initial_master_nodes: ["192.168.1.38","192.168.1.36"]         #启动服务并初始化，选举主节点列表

xpack.security.enabled: true                                           #开启xpack认证
xpack.license.self_generated.type: basic                               #启用基本xpack功能的许可证
xpack.security.transport.ssl.enabled: true                             #开启集群内，ssl安全认证
xpack.security.transport.ssl.verification_mode: certificate            #ssl证书模式
xpack.security.transport.ssl.keystore.path: elastic-certificates.p12   #ca证书路径
xpack.security.transport.ssl.truststore.path: elastic-certificates.p12 #ca密钥路径

http.cors.enabled: true                                              #开启跨域
http.cors.allow-origin: "*"                                          #支持所有域名
http.cors.allow-headers: Authorization,X-Requested-With,Content-Length,Content-Type #允许跨域的头部信息

 7、依赖

##升级glibc
# wget http://ftp.gnu.org/gnu/glibc/glibc-2.17.tar.gz
# tar -xvf glibc-2.17.tar.gz
# cd glibc-2.17
# mkdir build; cd build
# ../configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin
# make -j 8
# make install

 8、docker安装

"registry-mirrors": ["https://rjaaoail.mirror.aliyuncs.com"]

1）编写dockerfile

FROM  docker.io/elasticsearch:7.16.1
LABEL description="2022-11"
ADD elasticsearch.yml config/elasticsearch.yml
COPY Shanghai /etc/localtime 
RUN echo 'Asia/Shanghai' > /etc/timezone 

2）构建镜像并启动

# docker build  -t es:v1  -f /opt/es/Dockerfile
# docker run -d --name 'es' -p 19200:9200 -p 19300:9300  es:v1

3）设置密码

# docker  exec -it  26c bash
@26c elasticsearch-setup-passwords interactive
# curl -XGET --user elastic:123456 'http://127.0.0.1:19200'

 9、插件安装

1）在线安装
# elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.12.1/elasticsearch-analysis-ik-7.12.1.zip

2）离线安装
# cd plugins 
# mkdir ik   && cd ik
# wget https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.12.1/elasticsearch-analysis-ik-7.12.1.zip
# unzip  elasticsearch-analysis-ik-7.12.1.zip 
# mv elasticsearch-analysis-ik-7.12.1.zip  /opt/es/

3）其他
# elasticsearch-plugin list
# elasticsearch-plugin remove 
需要重启服务才生效
