问题1. Caused by: java.lang.RuntimeException: can not run elasticsearch as root
用户不能是root,新建一个用户即可
useadd perist
passwd perist
sudo vim /etc/sudoers
sudo su perist
启动 ./bin/elasticsearch
问题2. ERROR: [2] bootstrap checks failed
[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
[2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
sudo vim /etc/security/limits.conf
* soft nofile 65536
* hard nofile 65536
reboot
(临时修改可以用ulimit -n 65536)
sudo sysctl -w vm.max_map_count=262144
ulimit -n
问题3. ulimit: command not found
sudo vi /etc/pam.d/su
增加pam_limits.so模块引用
session required pam_limits.so
reboot
./bin/elasticsearch
started
