在 CentOS 7 上安装 Elasticsearch 和 Kibana

Created: November-22, 2018

要运行 Elasticsearch，计算机上需要 Java Runtime Environment(JRE)。Elasticsearch 需要 Java 7 或更高版本，并建议使用 Oracle JDK version 1.8.0_73。

因此，请确保你的系统中是否有 Java。如果没有，请按照以下步骤操作：

# Install wget with yum 
yum -y install wget

# Download the rpm jre-8u60-linux-x64.rpm for 64 bit 
wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u60-b27/jre-8u60-linux-x64.rpm"

# Download the rpm jre-8u101-linux-i586.rpm for 32 bit
wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u101-b13/jre-8u101-linux-i586.rpm"

# Install jre-.*.rpm
rpm -ivh jre-.*.rpm

Java 现在应该安装在 centOS 系统中。你可以查看：

java -version

下载并安装 elasticsearch

# Download elasticsearch-2.3.5.rpm 
wget https://download.elastic.co/elasticsearch/release/org/elasticsearch/distribution/rpm/elasticsearch/2.3.5/elasticsearch-2.3.5.rpm

# Install elasticsearch-.*.rpm
rpm -ivh elasticsearch-.*.rpm

在启动时将 elasticsearch 作为 systemd 服务运行

sudo systemctl daemon-reload
sudo systemctl enable elasticsearch
sudo systemctl start elasticsearch

# check the current status to ensure everything is okay.
systemctl status elasticsearch

安装 Kibana

首先在 rpm 上导入 GPG 密钥

sudo rpm --import http://packages.elastic.co/GPG-KEY-elasticsearch

然后创建一个本地存储库 kibana.repo

sudo vi /etc/yum.repos.d/kibana.repo

并添加以下内容：

[kibana-4.4]
name=Kibana repository for 4.4.x packages
baseurl=http://packages.elastic.co/kibana/4.4/centos
gpgcheck=1
gpgkey=http://packages.elastic.co/GPG-KEY-elasticsearch
enabled=1

现在按照以下命令安装 kibana：

yum -y install kibana

从以下开始：

systemctl start kibana

检查状态：

systemctl status kibana

你可以将其作为启动服务运行。

systemctl enable kibana
