解决警告
#1.backlog参数控制的是三次握手的时候server端收到client ack确认号之后的队列值
vim /etc/sysctl.conf
-------------------------
net.core.somaxconn=512
-------------------------
#2.
0、表示内核将检查是否有足够的可用内存供应用进程使用；如果有足够的可用内存,内存申请允许；否则,内存申请失败,并把错误返回给应用进程。
1、表示内核允许,分配所有的物理内存,而不管当前的内存状态如何。
2、表示内核允许,分配超过所有物理内存和交换空间总和的内存
vim/etc/sysctl.conf
-------------------------
vm.overcommit_memory=1
-------------------------
sysctl -p
#3.开启大页内存动态分配,需要关闭让redis负责内存管理。
echo never > /sys/kernel/mm/transparent_hugepage/enabled #这种方式临时生效，
Ubuntu 18.04.3默认就是never,但是还是需要以root用户执行一次
[root @centos7_m_1908_3 redis]#cat /sys/kernel/mm/transparent_hugepage/enabled
always madvise [never]
#写到配置文件中,永久保存
vim /etc/rc.d/rc.local #ubuntu没有文件/etc/rc.d/rc.local文件,centos有
echo never > /sys/kernel/mm/transparent_hugepage/enabled
