Configure elasticsearch port and ip

Enter the config folder, which contains an elasticsearch. yml file. Use the vim elasticsearch. yml command to edit the file and add the following

Error 3 needs to be fixed/etc/sysctl. conf

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

Edit the file using the command vim/etc/sysctl. conf, adding the following to the file 


 Plus vm.max_map_count=262144

Need to make the change file effective, implement sysctl-p 


[root@localhost etc]# sysctl -p
vm.max_map_count = 262144
