Daily record - Docker installation elasticsearch

1. Install Docker

1. Uninstall the old version of docker

yum remove docker  docker-common docker-selinux docker-engine

2. Install the software package

yum install -y yum-utils device-mapper-persistent-data lvm2

3. Set up Ali warehouse

yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

4. View the docker version

yum list docker-ce --showduplicates | sort -r

5. Install docker

yum -y install docker-ce-18.03.1.ce

6. Start docker

systemctl start docker

2. Docker command

basic command

1. Start

systemctl stop docker

2. close

systemctl stop docker

3. Restart

systemctl restart docker

4. View information such as images and containers

docker info

5. View version information

docker version

6. View the running status of docker

systemctl status docker

mirror command

1. Query the docker image list

docker images

2. Query by image name

docker search 镜像名称

3. Delete the mirror image

docker rmi IMAGE ID

container command

1. Query containers (only display running containers)

docker ps

2. Query containers (display all containers, including those that are not running)

docker ps -a

3. Close the container

docker container stop CONTAINER ID

4. Start the container

docker container start CONTAINER ID

5. Restart the container

docker container restart CONTAINER ID

6. Delete the container (one image can have multiple containers)

docker rm CONTAINER ID

log command

1. Query the container running log

docker logs -f 容器名称
docker logs -f elasticsearch

3. Docker install elasticsearch

1. Create a host data mount directory and configure permissions

Don't store data in containers, which is
one of the official Docker tips for using containers. Containers can be stopped or deleted at any time. When the container is rmed, the data in the container will be lost. In order to avoid data loss, users can use data volume mount to store data.

That's why the following directory of files is created

[root@localhost ~]# cd /home/
[root@localhost home]# mkdir es7/config -p
[root@localhost home]# mkdir es7/data -p
[root@localhost home]# mkdir es7/plugins -p
[root@localhost home]# cd es7/
[root@localhost es7]# chmod -R 777 /home/es7/

2. Add configuration file

[root@localhost home]# cd /es7/config
[root@localhost config]# touch elasticsearch.yml
[root@localhost config]# vim elasticsearch.yml

Then add in elasticsearch.yml:

network.host: 0.0.0.0
# 可访问IP
http.port: 9200
transport.port: 9300
# 跨域
http.cors.enabled: true
http.cors.allow-origin: "*"

3. Pull the image

docker pull elasticsearch:7.6.2

#docker pull elasticsearch:$version
#When pulling the image, you can specify the version, if not specified, the latest is used by default

4. Create a container

docker run --name elasticsearch -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -e "ES_JAVA_OPS=-Xms2g -Xmx2g" -v /home/es7/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /home/es7/data:/usr/share/elasticsearch/data -v /home/es7/plugins:/usr/share/elasticsearch/plugins --restart=always -d elasticsearch:7.6.2

5. The browser checks whether elasticsearch starts successfully

http://ip:9200/

4. Elasticsearch installs ik Chinese word breaker

ps: The word breaker version should be consistent with your es version, otherwise the installation will fail

1. Download the tokenizer

https://github.com/medcl/elasticsearch-analysis-ik/releases/tag/v7.6.2

2. Install ik

/home/es7/plugins/i

[root@localhost plugins]# mkdir ik -p
[root@localhost plugins]# cd ik
[root@localhost ik]# unzip elasticsearch-analysis-ik-7.6.2.zip

The latter is to restart elasticsearch

3. Test ik

5. Install ElasticSearch-head

1. Install nodejs

download

wget https://nodejs.org/dist/v14.17.4/node-v14.17.4-linux-x64.tar.xz

decompress

tar xf node-v14.17.4-linux-x64.tar.xz

Add environment variables

vim /etc/profile

Add at the end of the file

export NODEJS_HOME=/nodejs安装目录
export PATH=$NODEJS_HOME/bin:$PATH

refresh configuration

source /etc/profile

Confirm whether the installation is successful, check the version number

node -v

npm -v

2. Install elasticsearch-head

download package

https://codeload.github.com/mobz/elasticsearch-head/zip/refs/heads/master

unzip files

unzip elasticsearch-head-master.zip

Go into the elasticsearch-head-maste directory and install node_module

npm install

Background process

nohup npm run start &

Execute exit at last, otherwise it cannot run in the background

exit

The elasticsearch-head port is 9100

Six, ElasticSearch configuration to open the account password

1. Modify elasticsearch.yml

network.host: 0.0.0.0

# 可访问IP
http.port: 9200
transport.port: 9300

# # 跨域
http.cors.enabled: true
http.cors.allow-origin: "*"

# 开启账户密码验证
http.cors.allow-headers: Authorization,X-Requested-With,Content-Length,Content-Type
xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true

2. Restart elasticsearch

docker container restart CONTAINER ID

3. Go inside the container

#docker exec -it container name bash

docker exec -it elasticsearch bash

4. Set the passwords of elastic, apm_system, kibana, kibana_system, logstash_system, beats_system, remote_monitoring_user users

bin/elasticsearch-setup-passwords interactive

7. ElasticSearch-head requires account password login

127.0.0.1:9200?auth_user=elastic&auth_password=elastic
