桃扇骨 2022-05-11 12:52 216阅读 0赞

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“;

12、启动head  
cd /usr/local/elasticsearch-head-master/node\_modules/.bin  
cd /usr/local/elasticsearch-head-master/node\_modules/.bin/  
./grunt server &

13、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

14、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 &
