CentOS7上elasticsearch5.0启动失败

CentOS7上elasticsearch5.0启动失败 问题描述:
最新版本5.0release了,想着装上试试,结果一上来就报了两个错,然后就退出了,如下:

$ ./elasticsearch...ERROR: bootstrap checks failedmax file descriptors [4096] for elasticsearch process likely too low, increase to at least [65536]max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144][2016-10-31T04:55:45,240][INFO ][o.e.n.Node ] [vJDcSkt] stopping ...[2016-10-31T04:55:45,249][INFO ][o.e.n.Node ] [vJDcSkt] stopped[2016-10-31T04:55:45,249][INFO ][o.e.n.Node ] [vJDcSkt] closing ...[2016-10-31T04:55:45,257][INFO ][o.e.n.Node ] [vJDcSkt] closed 解决办法: 问题1: max file descriptors [4096] for elasticsearch process likely too low, increase to at least [65536]
修改/etc/security/limits.conf文件,添加或修改如下行:

  • hard nofile 65536* soft nofile 65536 问题2: max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144]
    使用下面的方法临时使其生效

$ sudo sysctl -w vm.max_map_count=262144
或者修改 /etc/sysctl.conf 文件,添加 “vm.max_map_count”设置

设置后,可以使用

$ sysctl -a
