CentOS 7.7系统安装Redis 6.0.3

前提操作

避免出现如下的错误

yum -y install gcc tcl
yum -y install centos-release-scl
yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils
echo "source /opt/rh/devtoolset-9/enable" >> /etc/profile

1.下载Redis

下载地址：https://redis.io/

wget http://download.redis.io/releases/redis-6.0.3.tar.gz

2.安装Redis

2.1编译Redis

tar -zxv -f redis-6.0.3.tar.gz -C /usr/local/
cd redis-6.0.3
make MALLOC=libc
make test

在redis根目录下执行make install命令，此命令会将redis/src下的一些脚本拷贝到/usr/local/bin/目录下，

因为/usr/local/bin/目录已经在path环境变量中配置了，所以执行此命令的目的是在任何目录下都可以直接启动停止redis。

# make install

常见错误

解决办法:

安装gcc:yum install gcc

解决办法：

查看gcc版本是否在5.3以上，CentOS7默认安装4.8.5。

升级gcc到5.3以上版本，升级到gcc 9

gcc -v
