1:elasticserach安装

rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch

Create a file called elasticsearch.repo in the /etc/yum.repos.d/ directory for RedHat based distributions, or in the /etc/zypp/repos.d/ directory for OpenSuSE based distributions, containing:

[elasticsearch]
name=Elasticsearch repository for 7.x packages
baseurl=https://artifacts.elastic.co/packages/7.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=0
autorefresh=1
type=rpm-md

And your repository is ready for use. You can now install Elasticsearch with one of the following commands:

sudo yum install --enablerepo=elasticsearch elasticsearch 

2：kibana安装

rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch

Create a file called elasticsearch.repo in the /etc/yum.repos.d/ directory for RedHat based distributions, or in the /etc/zypp/repos.d/ directory for OpenSuSE based distributions, containing:

[elasticsearch]
name=Elasticsearch repository for 7.x packages
baseurl=https://artifacts.elastic.co/packages/7.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch

And your repository is ready for use. You can now install Elasticsearch with one of the following commands:

sudo yum install --enablerepo=elasticsearch elasticsearch 

3：jdk

vi /etc/profile 

#文末添加以下配置

export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE HISTCONTROL

export JAVA_HOME=/usr/share/elasticsearch/jdk

export PATH=$JAVA_HOME/bin:$PATH

export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

#使变量生效

source /etc/profile

 

如果更改版本，yum remove elasticsearch

rm -rf  /var/lib/elasticsearch  /usr/share/elastucsearch

里面有node_lock 要删除改文件夹

kibana 同理

题外修改环境变量

 cat ~/.bashrc 

export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE HISTCONTROL
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

 source ~/.bashrc
