Adjust system configuration based on log prompts

echo "vm.overcommit_memory = 1" >>/etc/sysctl.conf; sysctl-p

echo never >/sys/kernel/mm/transparent_hugepage/enabled and adding this line to the/etc/rc.local will still take effect after the host restarts

echo "Net.core.somaxconn = 2048" >>/etc/sysctl.conf;sysctl-p

And then restart Redis
