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
