elasticsearch5.3linux集群

必须安装jdk8以上

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.3.0.zip

mkdir ela1
mkdir ela2

cp elasticsearch-5.3.0.zip  ela1
cp elasticsearch-5.3.0.zip  ela2


unzip elasticsearch-5.3.0.zip

vi /data1/elasticsearch/ela2/elasticsearch-5.3.0/config/elasticsearch.yml


因为安全问题elasticsearch 不让用root用户直接运行，所以要创建新用户


第一步：liunx创建新用户  adduser XXX    然后给创建的用户加密码 passwd XXX    输入两次密码。


第二步：切换刚才创建的用户 su XXX  然后执行elasticsearch  会显示Permission denied 权限不足。


第三步：给新建的XXX赋权限，chmod 777 *  这个不行，因为这个用户本身就没有权限，肯定自己不能给自己付权限。所以要用root用户登录付权限。


第四步：root给XXX赋权限，chown -R XXX /你的elasticsearch安装目录。


然后执行成功。



sudo chown -R noroot:noroot elasticsearch


/data1/elasticsearch/ela1/elasticsearch-5.3.0/bin/elasticsearch -d
/data1/elasticsearch/ela2/elasticsearch-5.3.0/bin/elasticsearch -d
