CentOS7上elasticsearch5.0启动失败

解决方法:

1.增大文件描述符和内存锁定问题

[[email protected] ~]#  cat >>  /etc/security/limits.conf << END

elasticsearch  soft  memlock  unlimited

elasticsearch  hard  memlock  unlimited

*        hard    nofile           65536

*        soft    nofile           65536

END

2. max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144]

[[email protected] ~]# echo "vm.max_map_count = 262144" >> /etc/sysctl.conf

[[email protected] ~]# sysctl -p

vm.max_map_count = 262144
