Docker初见（五）Docker 安装ES和Kibana

作者: Mr_ZhaiDK | 来源:发表于2020-09-23 09:24 被阅读0次

本次安装ES和Kibana版本如下：

elasticsearch 6.8.3
kibana 6.8.3
elasticsearch-head 5 前端框架

1.安装elasticsearch6.8.3

1）拉取镜像

docker pull elasticsearch:6.8.3

2）创建配置文件
想要建几台机器的集群就创建几个配置文件，需要修改的参数为node.name、http.port、transport.tcp.port、discovery.zen.ping.unicast.hosts

本次创建2台docker的es集群，使用docker容器所在服务器的ip：192.168.130.131，端口分别使用9200、9300、9201、9301

#开放防火墙端口
firewall-cmd --add-port=9300/tcp
firewall-cmd --add-port=9301/tcp
#创建文件夹
mkdir /home/es
cd  /home/es/
#创建配置文件夹
mkdir  /home/es/config
#创建数据挂载文件夹
mkdir data1
mkdir data2
#赋权限
chmod 777 data1 data2
#创建插件挂载文件夹
mkdir  plugins1
mkdir  plugins2
#创建配置文件
cd  /home/es/config
vi es1.yml
vi es2.yml

然后创建一个es1.yml配置文件里面的内容为

cluster.name: elasticsearch-cluster
node.name: es-node1
network.host: 0.0.0.0
network.publish_host: 192.168.130.131
http.port: 9200
transport.tcp.port: 9300
http.cors.enabled: true
http.cors.allow-origin: "*"
node.master: true
node.data: true
discovery.zen.ping.unicast.hosts: ["192.168.130.131:9300","192.168.130.131:9301"]
discovery.zen.minimum_master_nodes: 1

然后创建一个es2.yml配置文件里面的内容为

cluster.name: elasticsearch-cluster
node.name: es-node2
network.host: 0.0.0.0
network.publish_host: 192.168.130.131
http.port: 9201
transport.tcp.port: 9301
http.cors.enabled: true
http.cors.allow-origin: "*"
node.master: true
node.data: true
discovery.zen.ping.unicast.hosts: ["192.168.130.131:9300","192.168.130.131:9300"]
discovery.zen.minimum_master_nodes: 1

3）调高JVM线程数限制数量
在centos窗口中，修改配置sysctl.conf

vi /etc/sysctl.conf

在最后加入如下内容：

vm.max_map_count=262144

启用配置：

sysctl -p

注：这一步是为了防止启动容器时，报出如下错误：
bootstrap checks failed max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144]

4）运行镜像

docker run -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -dit -p 9200:9200 -p 9300:9300 \
-v /home/es/config/es1.yml:/usr/share/elasticsearch/config/elasticsearch.yml \
-v /home/es/plugins1:/usr/share/elasticsearch/plugins \
-v /home/es/data1:/usr/share/elasticsearch/data --name ES01 elasticsearch:6.8.3

docker run -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -d -p 9201:9201 -p 9301:9301 \
-v /home/es/config/es2.yml:/usr/share/elasticsearch/config/elasticsearch.yml  \
-v /home/es/plugins2:/usr/share/elasticsearch/plugins \
-v /home/es/data2:/usr/share/elasticsearch/data --name ES02 elasticsearch:6.8.3

5）测试站点是否成功
在浏览器地址栏访问http://192.168.130.131:9200/_cat/nodes?pretty查看节点状态
如果成功，显示如下：

ES集群节点信息

*6）增加用户名密码验证
获取集群证书

#创建文件夹
cd /home/es
mkdir /home/es/certificates
cd certificates

#查看启动的容器
[root@localhost nacos]# docker ps
CONTAINER ID        IMAGE                 COMMAND                  CREATED             STATUS              PORTS                                                                NAMES

#进入其中一个容器，如ES01-->5f477f1a7a7e
docker exec -it ES01 /bin/bash 

#配置生成SSL，在主服务器上生成就行
bin/elasticsearch-certgen

#退出容器
exit

#从容器中拷贝证书
docker cp ES01:/usr/share/elasticsearch/cert.zip .

#解压
unzip cert.zip

复制yml配置文件，在es01.yml、es02.yml中添加下列内容，生成es1-auth.yml、es2-auth.yml
es1-auth.yml内容添加：

# x-head 访问配置
http.cors.allow-headers: Authorization,X-Requested-With,Content-Length,Content-Type
# 开通高级权限后,打开安全配置功能
xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true
# 配置ssl和CA证书配置
xpack.ssl.key: /usr/share/elasticsearch/config/certificates/es/es.key
xpack.ssl.certificate: /usr/share/elasticsearch/config/certificates/es/es.crt
xpack.ssl.certificate_authorities: /usr/share/elasticsearch/config/certificates/ca/ca.crt

es2-auth.yml内容添加：

# 开通高级权限后,打开安全配置功能
xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true
# 配置ssl和CA证书配置
xpack.ssl.key: /usr/share/elasticsearch/config/certificates/es/es.key
xpack.ssl.certificate: /usr/share/elasticsearch/config/certificates/es/es.crt
xpack.ssl.certificate_authorities: /usr/share/elasticsearch/config/certificates/ca/ca.crt

停止并删除容器

#停止
docker stop ES01
docker stop ES02
#删除
docker rm ES01
docker rm ES02

用以下命令重新启动

docker run -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -dit -p 9200:9200 -p 9300:9300 \
-v /home/es/config/es1-auth.yml:/usr/share/elasticsearch/config/elasticsearch.yml \
-v /home/es/plugins1:/usr/share/elasticsearch/plugins \
-v /home/es/data1:/usr/share/elasticsearch/data \
-v /home/es/certificates/:/usr/share/elasticsearch/config/certificates/ \
--name ES01 elasticsearch:6.8.3

docker run -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -d -p 9201:9201 -p 9301:9301 \
-v /home/es/config/es2-auth.yml:/usr/share/elasticsearch/config/elasticsearch.yml  \
-v /home/es/plugins2:/usr/share/elasticsearch/plugins \
-v /home/es/data2:/usr/share/elasticsearch/data \
-v /home/es/certificates/:/usr/share/elasticsearch/config/certificates/ \
--name ES02 elasticsearch:6.8.3

宿主机的端口允许其它计算机访问，但是不允许来自本机的 Docker 容器访问。必须通过设置 firewalld 规则允许本机的 Docker 容器访问，可以通过在 /etc/firewalld/zones/public.xml 中添加防火墙规则避免这个问题：

<rule family="ipv4">
    <source address="172.17.0.0/16" />
    <accept />
</rule>

注意这里的 172.17.0.0/16 可以匹配 172.17.xx.xx IP 段的所有 IP。
之后重启下防火墙:

systemctl restart firewalld

开通高级功能后,如何设置登录账号和密码,开启登录验证功能

# 进入主容器
docker exec -it ES01 /bin/bash 

#自定义设置elastic、kibana…等所有工具的登录密码 
bin/elasticsearch-setup-passwords interactive

完成

2.安装elasticsearch-head前端框架

1）拉取镜像

docker pull mobz/elasticsearch-head:5

2）新建Gruntfile.js

cd /home/es/config
vi Gruntfile.js

内容如下：

module.exports = function(grunt) {

    var fileSets = require("./grunt_fileSets.js");

    // Project configuration.
    grunt.initConfig({
        clean: {
            _site: {
                src: ['_site']
            }
        },
        concat: {
            vendorjs: {
                src: fileSets.vendorJs,
                dest: '_site/vendor.js'
            },
            vendorcss: {
                src: fileSets.vendorCss,
                dest: '_site/vendor.css'
            },
            appjs: {
                src: fileSets.srcJs,
                dest: '_site/app.js'
            },
            appcss: {
                src: fileSets.srcCss,
                dest: '_site/app.css'
            }
        },

        copy: {
            site_index: {
                src: 'index.html',
                dest: '_site/index.html',
                options: {
                    process: function( src ) {
                        return src.replace(/_site\//g, "");
                    }
                }
            },
            base: {
                expand: true,
                cwd: 'src/app/base/',
                src: [ '*.gif', '*.png', '*.css' ],
                dest: '_site/base/'
            },
            iconFonts: {
                expand: true,
                cwd: 'src/vendor/font-awesome/fonts/',
                src: '**',
                dest: '_site/fonts'
            },
            i18n: {
                src: 'src/vendor/i18n/i18n.js',
                dest: '_site/i18n.js'
            },
            lang: {
                expand: true,
                cwd: 'src/app/lang/',
                src: '**',
                dest: '_site/lang/'
            }
        },

        jasmine: {
            task: {
                src: [ fileSets.vendorJs, 'src/vendor/i18n/i18n.js', 'src/app/lang/en_strings.js', fileSets.srcJs ],
                options: {
                    specs: 'src/app/**/*Spec.js',
                    helpers: 'test/spec/*Helper.js',
                    display: "short",
                    summary: true
                }
            }
        },

        watch: {
            "scripts": {
                files: ['src/**/*', 'test/spec/*' ],
                tasks: ['default'],
                options: {
                    spawn: false
                }
            },
            "grunt": {
                files: [ 'Gruntfile.js' ]
            }
        },

        connect: {
            server: {
                options: {
                    port: 9400,
                    base: '.',
                    keepalive: true
                }
            }
        }

    });

    grunt.loadNpmTasks('grunt-contrib-clean');
    grunt.loadNpmTasks('grunt-contrib-concat');
    grunt.loadNpmTasks('grunt-contrib-watch');
    grunt.loadNpmTasks('grunt-contrib-connect');
    grunt.loadNpmTasks('grunt-contrib-copy');
    grunt.loadNpmTasks('grunt-contrib-jasmine');

    // Default task(s).
    grunt.registerTask('default', ['clean', 'concat', 'copy', 'jasmine']);
    grunt.registerTask('server', ['connect:server']);
    grunt.registerTask('dev', [ 'default', 'watch' ]);

};

修改端口
3）启动容器

docker run -d -p 9400:9400 -v /home/es/config/Gruntfile.js:/usr/src/app/Gruntfile.js --name es-manager  mobz/elasticsearch-head:5

5）浏览器访问http://192.168.130.131:9400/

ES-Manager

3.安装kibana

#查看ES01的docker内容器
[root@localhost es]# docker inspect ES01 | grep IPAddress
            "SecondaryIPAddresses": null,
            "IPAddress": "172.17.0.2",
                    "IPAddress": "172.17.0.2",
#运行容器
docker run --name es-kibana -e ELASTICSEARCH_URL=http://172.17.0.2:9200  -p 5601:5601 -d kibana:6.8.3

参数ELASTICSEARCH_URL一定要是docker里面的内部地址，否则Kibana访问不到Elasticsearch。
成功如下图：
