docker安装elasticsearch

查看max_map_count的值 默认是65530

[root@localhost ~]# cat /proc/sys/vm/max_map_count                                                                                                                                          
65530   

重新设置max_map_count的值

[root@localhost ~]# sysctl -w vm.max_map_count=262144                                                                                                                                       
vm.max_map_count = 262144 

拉取镜像

[root@localhost ~]# docker pull elasticsearch:7.7.0
