When installing Redis, need to use gcc. If the system is networked, so direct use the following command to install networking.
yum -y install gcc
But if the system is not networked, then you need a way to install the offline. Proceed as follows:
1. Remove the system from the desired rpm package installed in the image CentOS7 (can also be obtained by other ways): extract the image file into the "Packages" directory, there are many packages rpm, taken following several:
mpfr-3.1.1-4.el7.x86_64.rpm libmpc-1.0.1-3.el7.x86_64.rpm kernel-headers-3.10.0-123.el7.x86_64.rpm glibc-headers-2.17-55.el7.x86_64.rpm glibc-devel-2.17-55.el7.x86_64.rpm cpp-4.8.2-16.el7.x86_64.rpm gcc-4.8.2-16.el7.x86_64.rpm
2. These packets uploaded to the system to be installed, the installation commands in the following order:
rpm -ivh mpfr-3.1.1-4.el7.x86_64.rpm rpm -ivh libmpc-1.0.1-3.el7.x86_64.rpm rpm -ivh kernel-headers-3.10.0-123.el7.x86_64.rpm rpm -ivh glibc-headers-2.17-55.el7.x86_64.rpm rpm -ivh glibc-devel-2.17-55.el7.x86_64.rpm rpm -ivh cpp-4.8.2-16.el7.x86_64.rpm rpm -ivh gcc-4.8.2-16.el7.x86_64.rpm
You can also use the following command unified installation:
rpm -Uvh *.rpm --nodeps --force
3. After successfully installed, verify
gcc -v
