安装

解压jdk并配置环境变量

# 解压java到/opt下
$ cd /opt
$ tar -zxvf jdk-11.0.1_linux-x64_bin.tar.gz
$ mv jdk-11.0.1 jdk11

# 配置java环境变量
$ touch /etc/profile.d/java.sh
$ echo "export JAVA_HOME=/opt/jdk11" >> /etc/profile.d/java.sh
$ echo "export PATH=$PATH:$JAVA_HOME/bin" >> /etc/profile.d/java.sh
$ source /etc/profile

解压elasticsearch

# 解压ES到/opt下
$ cd /opt
$ tar -zxvf elasticsearch-6.5.4.tar.gz
$ mv elasticsearch-6.5.4 elasticsearch

启动

elasticsearch出于安全原因，不能以root用户运行

创建elsearch用户组及elsearch用户

$ groupadd elsearch
$ useradd elsearch -g elsearch -p elasticsearch

更改文件所属用户及组

$ chown -R elsearch:elsearch  /opt/elasticsearch

启动

$ su - elsearch -c /opt/elasticsearch/bin/elasticsearch
