安装java环境
懒人模式:yum install java*
简单配置下:
vim /etc/profile
尾部加上:
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.171-8.b10.el7_5.x86_64 export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar export PATH=$PATH:$JAVA_HOME/bin
保存退出后使用命令更新配置
source /etc/profile
2.安装elasticsearch
由于ES不在yum的本地源,所以我们需要添加ES的yum配置。
下载并安装ES的yum公钥
rpm --import https://packages.elastic.co/GPG-KEY-elasticsearch
配置ES的yum源
vim /etc/yum.repos.d/elasticsearch.repo
输入下面的内容:
[elasticsearch-2.x] name=Elasticsearch repository for 2.x packages baseurl=http://packages.elastic.co/elasticsearch/2.x/centosgpgcheck=1gpgkey=http://packages.elastic.co/GPG-KEY-elasticsearchenabled=1
二、yum安装ES
更新yum的缓存
yum makecache
安装ES
yum install elasticsearch
三、测试ES
1、配置和启动ES服务器进程
/sbin/chkconfig --add elasticsearch
systemctl start elasticsearch
2、查看状态(可能遇到启动失败,如果遇到内存不足情况,弄点swap虚拟内存凑一下)
systemctl status elasticsearch
3、运行测试
curl -X GET localhost:9200
返回的json结果如下:
{ "name": "Mister One", "cluster_name": "elasticsearch", "cluster_uuid": "HGBnQTTDTpKlCJnMSXyHBg", "version": { "number": "2.4.6", "build_hash": "5376dca9f70f3abef96a77f4bb22720ace8240fd", "build_timestamp": "2017-07-18T12:17:44Z", "build_snapshot": false, "lucene_version": "5.5.4" }, "tagline": "You Know, for Search" }
四、通过IP访问ES的配置
四、通过IP访问ES的配置
1、打开/etc/elasticsearch/elasticsearch.yml
vim /etc/elasticsearch/elasticsearch.yml
55行的network.host,把后面改为0.0.0.0或者虚拟机ip地址,这样就可以在window系统用浏览器通过访问虚拟机的ip,正确访问效果如下
安装elasticsearch-head插件,用于监控
cd /usr/share/elasticsearch/bin
执行:
./plugin install mobz/elasticsearch-head
安装完成后,即可通过浏览器访问:
http://192.168.32.128:9200/_plugin/head/
php使用案例:
<?php require_once('vendor/autoload.php'); use Elasticsearch\ClientBuilder; function get_conn(){ $host = 'localhost'; $dbname = 'mraz'; $user = 'root'; $passwd = '111111'; $conn = new PDO("mysql:dbname=$dbname;host=$host",$user,$passwd); return $conn; } function create_index(){ //Elastic search php client $client = Elasticsearch\ClientBuilder::create()->setHosts(['192.168.32.128'])->build(); $sql = "SELECT * FROM emp"; $conn = get_conn(); $stmt = $conn->query($sql); $rtn = $stmt->fetchAll(); //delete index which already created $params = array(); $params['index'] = 'emp_index'; $client->indices()->delete($params); //create index on log_date,src_ip,dest_ip $rtnCount = count($rtn); for($i=0;$i<$rtnCount;$i++){ $params = array(); $params['body'] = array( 'id' => $rtn[$i]['id'], 'fdName' => $rtn[$i]['fdName'], 'fdAge' => $rtn[$i]['fdAge'], 'fdStatus' => $rtn[$i]['fdStatus'] ); $params['index'] = 'emp_index'; $params['type'] = 'emp_type'; //Document will be indexed to log_index/log_type/autogenerate_id $client->index($params); } echo 'create index done!'; } function search(){ //Elastic search php client $client = Elasticsearch\ClientBuilder::create()->build(); $params = array(); $params['index'] = 'emp_index'; $params['type'] = 'emp_type'; $params['body']['query']['match']['fdStatus'] = '1'; $params['body']['sort'] = array('fdAge'=>array('order'=>'desc')); $params['size'] = 3; $params['from'] = 1; $rtn = $client->search($params); var_dump($rtn); } set_time_limit(0); // create_index(); search(); ?>
