1、can not run elasticsearch as root

切换到非root用户

2、main ERROR Could not register mbeans java.security.AccessControlException: access denied ("javax.management.MBeanTrustPermission" "register")

改变elasticsearch文件夹所有者到当前用户

sudo chown -R noroot:noroot elasticsearch

3、max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

sudo vi /etc/sysctl.conf

添加下面配置：

vm.max_map_count=655360

并执行命令：

sudo sysctl -p

4、max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]

sudo vi /etc/security/limits.conf

添加如下内容:

* soft nofile 65536

* hard nofile 131072

* soft nproc 2048

* hard nproc 4096

sudo vi /etc/pam.d/common-session

添加 session required pam_limits.so

sudo vi /etc/pam.d/common-session-noninteractive

添加 session required pam_limits.so

如果安装到虚拟机中无法访问服务,可以修改elasticsearch.yml 中host地址
