binutils（Redis6安装）

redis6安装

Redis是c语言开发的，安装redis需要c语言的编译环境。

安装redis6最主要的一点是要用gcc5以上，而centos7的GCC版本为4.8.x, 所以安装之前必须升级GCC。

1.安装新版本的gcc软件包及依赖包

[root@TimeSync ~]# yum -y install centos-release-scl scl-utils-build

[root@TimeSync ~]# yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils

#临时启用，退出shell后会恢复原系统gcc版本：

[root@TimeSync ~]# scl enable devtoolset-9 bash

#永久启用：

[root@TimeSync ~]# echo "source /opt/rh/devtoolset-9/enable" >> /etc/profile

2.设置系统参数

[root@TimeSync ~]# echo never > /sys/kernel/mm/transparent_hugepage/enabled

[root@TimeSync ~]# echo 511 > /proc/sys/net/core/somaxconn

[root@TimeSync ~]# echo vm.overcommit_memory=1 >> /etc/sysctl.conf

[root@TimeSync ~]# echo net.core.somaxconn= 1024 >> /etc/sysctl.conf

[root@TimeSync ~]# sysctl -p

[root@TimeSync ~]# ulimit -n 65535

3.查看安装后的gcc版本

[root@TimeSync ~]# scl enable devtoolset-9 bash

[root@TimeSync ~]# gcc --version

gcc (GCC) 9.3.1 20200408 (Red Hat 9.3.1-2)

4.解压redis安装包

tar -zxvf redis-6.0.10.tar.gz -C /usr/local && mv redis-6.0.10 redis

cd redis

make && make test

make PREFIX=/usr/local/redis/ install

5.创建配置文件目录

mkdir -p /usr/local/redis/etc

命令安装目录：/usr/local/redis/bin

redis-benchmark: 性能测试工具，可以在自己本子运行，看看自己本子性能如何

redis-check-aof： 修复有问题的AOF文件，rdb和aof后面讲

redis-check-dump：修复有问题的dump.rdb文件

redis-sentinel： Redis集群使用

redis-server： Redis服务器启动命令

redis-cli： 客户端使用操作入口

6.启动redis

[root@TimeSync redis]# /usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf

129524:C 19 Oct 2022 14:15:30.326 # Redis version=6.0.16, bits=64, commit=00000000, modified=0, pid=129524, just started

[root@TimeSync redis]#

7.查看进程和端口

[root@TimeSync bin]# netstat -lantup |grep redis

tcp 0 0 127.0.0.1:6379 0.0.0.0:* LISTEN 129534/redis-server

[root@TimeSync bin]# ps -ef |grep redis |grep -v grep

root 129534 53547 0 14:18 pts/1 00:00:00 redis-server 127.0.0.1:6379

[root@TimeSync bin]#
