2台5.X版本的作ES集群用于Skywalking服务调用链路跟踪管理

系统环境：centos7.5
es版本：elasticsearch-5
jdk：1.8
主机ip
192.168.2.129
192.168.2.130

1、软件下载

cd /usr/local/
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.6.3.tar.gz

2、jdk安装

wget ftp://10.249.100.249/pub/jdk/jdk8/*

3、安装es

tar -zxvf elasticsearch-5.6.3.tar.gz
mv elasticsearch-5.6.3/ elasticsearch

4、建立data目录和log目录

mkdir -p /data/elasticsearch/data
mkdir -p /data/elasticsearch/logs

5、建立用户(es不能用root运行)

useradd es
chown -R es:es /usr/local/elasticsearch
chown -R es:es /data

6、系统参数优化

vim /usr/local/elasticsearch/config/jvm.options
-Xms4g
-Xmx4g

vi /etc/sysctl.conf
    vm.max_map_count=655360
    fs.file-max=655360


vi /etc/security/limits.conf
    es         soft   memlock      unlimited
    es        hard   memlock      unlimited
    

7、编辑配置文件

[root@ip-192-168-2-129 ~]# grep '^[a-z]' /usr/local/elasticsearch/config/elasticsearch.yml
cluster.name: es5.6.3
node.name: node-129
node.master: true
path.data: /data/elasticsearch/data
path.logs: /data/elasticsearch/logs
bootstrap.memory_lock: true
network.host: 0.0.0.0
http.port: 9200
transport.tcp.port: 9300
discovery.zen.ping.unicast.hosts: ["192.168.2.129", "192.168.2.130"]
gateway.recover_after_nodes: 1
http.cors.enabled: true
http.cors.allow-origin: "*"

[root@ip-192-168-2-130 ~]# grep '^[a-z]' /usr/local/elasticsearch/config/elasticsearch.yml
cluster.name: es5.6.3
node.name: node-130
node.master: true
path.data: /data/elasticsearch/data
path.logs: /data/elasticsearch/logs
bootstrap.memory_lock: true
network.host: 0.0.0.0
http.port: 9200
transport.tcp.port: 9300
discovery.zen.ping.unicast.hosts: ["192.168.2.129", "192.168.2.130"]
gateway.recover_after_nodes: 1
http.cors.enabled: true
http.cors.allow-origin: "*"

8、启动

分别启动两台服务
su - es -c "/usr/local/elasticsearch/bin/elasticsearch &"

9、head插件安装

wget https://github.com/mobz/elasticsearch-head/archive/master.zip
unzip elasticsearch-5.6.3.tar.gz
cd elasticsearch-head-master

10、安装node

curl -sL -o /etc/yum.repos.d/khara-nodejs.repo https://copr.fedoraproject.org/coprs/khara/nodejs/repo/epel-7/khara-nodejs-epel-7.repo
yum install -y nodejs nodejs-npm

11、安装grunt

cd /usr/lib/node_modules/npm/
npm install grunt-cli
npm install grunt

12、修改配置

修改vim Gruntfile.js文件：增加hostname属性，设置为*

connect: {
    server: {
        options: {
            port: 9100,
            hostname: '*',
            base: '.',
            keepalive: true
        }
    }
}

修改 vim _site/app.js 文件：修改head的连接地址
this.base_uri = this.config.base_uri || this.prefs.get(“app-base_uri”) || “http://localhost:9200“;
修改成ElasticSearch的机器地址
this.base_uri = this.config.base_uri || this.prefs.get(“app-base_uri”) || “http://192.168.2.130:9200“;

13、启动head

cd /usr/local/elasticsearch-head-master/node_modules/.bin
cd /usr/local/elasticsearch-head-master/node_modules/.bin/
./grunt server &

14、网页访问

http://192.168.2.129:9100
http://192.168.2.130:9100
如果出现集群连不上的状态：https://www.cnblogs.com/wendu/p/6549806.html

15、设置开机启动

su - es -c "/usr/local/elasticsearch/bin/elasticsearch -d"
cd /usr/local/elasticsearch-head-master/node_modules/.bin/
./grunt server &
