这篇文章给大家分享的是有关如何编译安装 redisd 的内容。丸趣 TV 小编觉得挺实用的，因此分享给大家做个参考，一起跟随丸趣 TV 小编过来看看吧。
安装方法：yum 安装
查看 yum 仓库 redis 版本
[root@centos ~]# yum list redis

redis.x86_64 3.2.12-2.el7 myepelyum 安装 [root@centos ~]# yum install redis -y
启动服务并设为开机启动
[root@centos ~]# systemctl enable --now redis

tcp-backlog
The backlog argument defines the maximum length to which the queue of pending connections for sockfdmay grow. If a connection request arrives when the queue is full, the client may receive an error with an indication of ECONNREFUSED or, if the underlying protocol supports retransmission, the request may be ignored so that a later reattempt at connection succeeds.
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。
[root@centos ~]# echo 511 /proc/sys/net/core/somaxconn
vm.overcommit_memory0、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
[root@centos ~]# echo vm.overcommit_memory = 1 /etc/sysctl.conf
transparent hugepage
