CentOS7源码安装redis6

1.下载源码包

[root@localhost ~]# wget https://download.redis.io/releases/redis-6.2.8.tar.gz

2.安装依赖

  redis6需要gcc高版本

[root@localhost ~]# yum -y install centos-release-scl 
[root@localhost ~]# yum -y devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils
[root@localhost ~]# scl enable devtoolset-9 bash                                       （临时启用）
[root@localhost ~]# echo "source /opt/rh/devtoolset-9/enable" >> /etc/profile          （永久启用）

3.解压安装

[root@localhost ~]# tar -xvf redis-6.2.8.tar.gz -C /usr/local/
[root@localhost ~]# cd /usr/local/redis-6.2.8/
[root@localhost ~]# make  && make install

 4.启动redis

[root@localhost redis-6.2.8]# /usr/local/redis/bin/redis-server

Being disabled, it can can also cause failures without low memory condition, see https://github.com/jemalloc/jemalloc/issues/1328.

重新启动redis，正常
