The reason
From redis 6.0.0, building redis from source code needs C11 support.
The version of gcc in Centos7 is 4.8.5, but C11 was introduced in 4.9.
Solvution
Install Developer Toolset 7 to compile with gcc7.
yum install centos-release-scl devtoolset-7
This won’t update gcc 4.8.5 to 7 directly, it provides a virtual environment for gcc toolchain.
Use the following command enter the environment.
scl enable devtoolset-7 bash
Install Redis
wget https://github.com/antirez/redis/archive/6.0.1.tar.gz
tar -xvzf 6.0.1.tar.gz
cd redis-6.0.1
./configure
make
make install
