kernel.shmmax = 536870912
fs.file-max = 6815744
fs.aio-max-nr = 1048576

net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576

net.ipv4.ip_local_port_range = 9000 65500

run sudo /etc/sysctl -p


2) Open /etc/limits.conf and insert the following :

ges hard nofile 65536
