编译安装redisd
安装方法：
yum安装
- 查看yum仓库redis版本
[root@centos ~]# yum list redis
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
Available Packages
redis.x86_64 3.2.12-2.el7 myepel
- yum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
Created symlink from /etc/systemd/system/multi-user.target.wants/redis.service to /usr/lib/systemd/system/redis.service.
- 查看redis端口
[root@centos ~]# ss -ntl

- 解决当前的警告提示
- 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_memory
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
[root@centos ~]# echo "vm.overcommit_memory = 1" >/etc/sysctl.conf
- transparent hugepage
大页内存动态分配，需要关闭让redis 负责内存管理。
[root@centos ~]# echo never > /sys/kernel/mm/transparent_hugepage/enabled
- 重启一下服务
# 再次启动服务，警告信息没有了。
