Installing the Redis Database

Download Redis version: https://redis.io/download i downloaded: redis-3.0.6

After download, TAR-ZXVF redis-3.0.6 on Linux, go to redis-3.0.6 directory, compile with make

When installing Redis, when compiling with the make command, throw an exception
[[email protected] redis-3.0.6]# make
CD src && make all
MAKE[1]: Entering directory '/USR/LOCAL/DEVELOPMENT/REDIS-3.0.6/SRC '

This is the reason that the local Linux does not have GCC installed because my Linux is not networked so use offline installation, that is, first download the RPM package on Windows, and then move to Linux manually installed
Steps to install GCC:
Download the RPM package required for GCC in the ftp://mirror.switch.ch/pool/4/mirror/scientificlinux/6.8/x86_64/os/Packages/connection
From the Internet, the following packages are required
cloog-ppl-0.15.7-1.2.el6.x86_64.rpm
cpp-4.4.7-17.el6.x86_64.rpm
gcc-4.4.7-17.el6.x86_64.rpm
gcc-c++-4.4.7-17.el6.x86_64.rpm
glibc-devel-2.12-1.192.el6.x86_64.rpm
glibc-headers-2.12-1.192.el6.x86_64.rpm
kernel-headers-2.6.32-642.el6.x86_64.rpm
libgomp-4.4.7-17.el6.x86_64.rpm
libstdc++-devel-4.4.7-17.el6.x86_64.rpm
mpfr-2.4.1-6.el6.x86_64.rpm
ppl-0.10.2-11.el6.x86_64.rpm

After downloading, create a new directory (in the directory where you install the app), and place the newly downloaded packages in the directory, using
[Email protected] gcc]# RPM-UVH ppl-0.10.2-11.el6.x86_64.rpm
Warning:ppl-0.10.2-11.el6.x86_64.rpm:header V4 dsa/sha1 Signature, key ID 192a7d7d:nokey
error:failed dependencies:
Libgmp.so.3 () (64bit) is needed by ppl-0.10.2-11.el6.x86_64

You can see that using RPM-IVH has dependency problems, so I use the Ignore dependency, force installation
[Email protected] gcc]# RPM-IVH cloog-ppl-0.15.7-1.2.el6.x86_64.rpm--nodeps--force

To see if GCC is installed successfully

After all RPM packages are installed, use the make command to throw the following exception

There's a redme file in the Redis directory, and there's a
Selecting a Non-default memory allocator when building Redis are done by setting
The ' MALLOC ' environment variable. Redis is compiled and linked against LIBC
malloc by default, with the exception of Jemalloc being the default on Linux
Systems. This default is picked because Jemalloc has proven to having fewer
Fragmentation problems than libc malloc.

To force compiling against libc malloc, use:

% make MALLOC=LIBC

To compile against Jemalloc in Mac OS X systems, use:

% make Malloc=jemalloc

Verbose Build

This paragraph probably means that selecting a memory allocator on Redis is set by the malloc variable, and Jemalloc is the default value for Linux. If you do not have jemalloc in Linux, throw this exception.
Using Make MALLOC=LIBC
