一、Redis官网
本文使用的是当下最新的稳定版本V6.0.9
二、安装Redis
1、解压
tar -zxf redis-6.0.9.tar.gz
2、编译源码
make
注：make过程可能会报错，错误信息如下
In file included from server.c:30:0:
server.h:1072:5: error: expected specifier-qualifier-list before ‘_Atomic’
_Atomic unsigned int lruclock; /* Clock for LRU eviction */
^
server.c: In function ‘serverLogRaw’:
server.c:1031:31: error: ‘struct redisServer’ has no member named ‘logfile’
int log_to_stdout = server.logfile[0] == '\0';
^
server.c:1034:23: error: ‘struct redisServer’ has no member named ‘verbosity’
if (level < server.verbosity) return;
^
server.c:1036:47: error: ‘struct redisServer’ has no member named ‘logfile’
fp = log_to_stdout ? stdout : fopen(server.logfile,"a");
^
server.c:1049:47: error: ‘struct redisServer’ has no member named ‘timezone’
nolocks_localtime(&tm,tv.tv_sec,server.timezone,server.daylight_active);
^
........错误原因：GCC版本低了，新版的Redis用到了c11，系统默认自带版本是4.8.5
[root@10 redis-6.0.9]# gcc --version
gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-39)

解决方法：需要更新gcc到5.4版本以上，安装命令如下
yum groupinstall "Development Tools"
strings /usr/lib64/libstdc++.so.6 | grep GLIBC
cd /usr/local/src/
wget http://ftp.gnu.org/gnu/gcc/gcc-10.2.0/gcc-10.2.0.tar.gz //速度较慢，使用镜像站：wget http://mirror.hust.edu.cn/gnu/gcc/gcc-10.2.0/gcc-10.2.0.tar.gz
tar -zxf gcc-10.2.0.tar.gz
cd gcc-10.2.0
./contrib/download_prerequisites
./configure -enable-checking=release -enable-languages=c,c++ -disable-multilib
make -j4
ls /usr/local/bin | grep gcc
make install
由于安装过程很慢，另一种升级方式：
yum -y install centos-release-scl
yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils
scl enable devtoolset-9 bash
echo "source /opt/rh/devtoolset-9/enable" >> /etc/profile
gcc -v
3、安装
make install
[root@10 redis-6.0.9]# cd src/
[root@10 src]# make install
Hint: It's a good idea to run 'make test' ;)
INSTALL install
INSTALL install
INSTALL install
INSTALL install
INSTALL install
三、部署Redis
1、创建bin和etc文件夹
[root@10 redis-6.0.9]# mkdir etc
[root@10 redis-6.0.9]# mkdir bin
2、移动文件
[root@10 src]# mv mkreleasehdr.sh redis-benchmark redis-check-aof redis-check-rdb redis-cli redis-server ../bin/
[root@10 src]# cd ../bin/
[root@10 bin]# ls
mkreleasehdr.sh redis-check-aof redis-cli
redis-benchmark redis-check-rdb redis-server
[root@10 bin]# cd ..
[root@10 redis-6.0.9]# mv redis.conf etc/
[root@10 redis-6.0.9]# cd etc
[root@10 etc]# ls
redis.conf
四、启动Redis
[root@10 bin]# ./redis-server
