目的
- 本文安装一个无权限Elasticsearch 6来作为测试环境试用。
- 开放跨域
- 解决centos7里的坑
- 下次安装自己也可以参考
创建用户(Elasticsearch 不能使用root运行)
groupadd elsearch
useradd elsearch -g elsearch -p /opt/elasticsearch-6.2.4
安装依赖的JDK环境
cd /opt/
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/8u141-b15/336fa29ff2bb4ef291e347e091f7f4a7/jdk-8u141-linux-x64.tar.gz"
tar xzf jdk-8u141-linux-x64.tar.gz
加入环境变量 vi /home/elsearch/.bash_profile
su elsearch
PATH=$PATH:$HOME/bin
JAVA_HOME=/opt/jdk1.8.0_141
JAVA_JRE=$JAVA_HOME/jre
CLASS_PATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
export JAVA_HOME JRE_HOME CLASS_PATH PATH
source .bash_profile
验证是否安装成功.
java -version
java version "1.8.0_141"
Java(TM) SE Runtime Environment (build 1.8.0_141-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.141-b15, mixed mode)
开始
然后开始安elasticsearch，直接官网即可 https://www.elastic.co/downloads/elasticsearch,下面是我的操作记录。
su root
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.2.4.tar.gz
tar -xzvf elasticsearch-6.2.4.tar.gz
chown -R elsearch:elsearch /opt/elasticsearch-6.2.4
su research
/opt/elasticsearch-6.2.4/bin/elasticsearch -d
- curl http://localhost:9200/
[elsearch@elastic opt]$ curl http://localhost:9200/
