elasticsearch docker官方镜像无法运行

elasticsearch5.1 docker官方镜像运行时会报错:

ERROR: bootstrap checks failed
max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

那是因为vm.max_map_count达不到es的最低要求262144,修改方式有两种:

#一次生效
sudo sysctl -w vm.max_map_count=262144
#永久生效
sudo vi /etc/sysctl.conf
#添加这一行
vm.max_map_count=262144

#加载配置
sudo sysctl -p
