异常
[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
[2]: max number of threads [3818] for user [es] is too low, increase to at least [4096]
[3]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
解决
修改 etc/security/limits.conf
sudo vi /etc/security/limits.conf
在文件最后面加上
* soft nofile 65536
* hard nofile 65536
* soft nproc 4096
* hard nproc 4096
注：*后面有空格
修改 /etc/sysctl.conf
sudo vi /etc/sysctl.conf
在文件最后面加上
vm.max_map_count=262144
配置重新生效
sysctl -p
