配置 elasticsearch 集群时出错

Question

I'm configuring three node elasticsearch cluster. I'm getting following error while try to start first node using following

startup command

[cloud_user@mishai3c elasticsearch-6.2.4]$ ./bin/elasticsearch -d -p pid

error message

[2019-11-11T04:50:39,634][INFO ][o.e.b.BootstrapChecks    ] [master] bound or publishing to a non-loopback address, enforcing bootstrap checks

I have tried to set up ulimit in /etc/security/limits.conf file by adding following line

@cloud_user      hard    nproc           4096

It's highly appriciate if anyone can help

Answer 1

After changing limit.conf file,I have checked max thread limit by running ulimit -u command in terminal it still show previous value then Then I logout and log into server and run ulimit -u command then it show 4096.

Then I tried to start elasticsearch it works
