CentOS7.x安裝Redis6.0.1
1.下載Redis
下載Redis最新穩定版6.0.1，https://redis.io/
[solang@solang ~]$ wget http://download.redis.io/releases/redis-6.0.1.tar.gz
2.安裝Redis
2.1編譯Redis
[solang@solang ~]$ tar -zxf redis-6.0.1.tar.gz -C /usr/local/
[solang@solang ~]$ cd /usr/local/redis-6.0.1/
[solang@solang redis-6.0.1]$ make
執行make後有錯
make[3]: cc: Command not found
make[3]: *** [net.o] Error 127
make[3]: Leaving directory `/usr/local/redis-6.0.1/deps/hiredis'
make[2]: *** [hiredis] Error 2
make[2]: Leaving directory `/usr/local/redis-6.0.1/deps'
make[1]: [persist-settings] Error 2 (ignored)
CC adlist.o
/bin/sh: cc: command not found
make[1]: *** [adlist.o] Error 127
make[1]: Leaving directory `/usr/local/redis-6.0.1/src'
make: *** [all] Error 2
編譯Redis的時候需要安裝gcc
[root@solang ~]# yum -y install gcc
以普通用戶再次編譯
[solang@solang redis-6.0.1]$ make

查看gcc版本是否在5.3以上，CentOS7默認安裝4.8.5。
[solang@solang redis-6.0.1]$ gcc -v

2.2升級gcc版本
升級gcc到5.3以上版本，升級到gcc 9版本
[root@solang ~]# yum -y install centos-release-scl
[root@solang ~]# yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils

需要注意的是scl命令啓用只是臨時的，退出shell或重新打開一個shell就會恢復原系統gcc版本。
執行以下命令永久使用gcc 9，其中/opt/rh/devtoolset-9/是scl命令啓用後gcc -v中的COLLECT_LTO_WRAPPER路徑前綴。
[root@solang ~]# echo "source /opt/rh/devtoolset-9/enable" >> /etc/profile
注：執行完此命令後，其它的shell窗口需要關閉重新打開才生效。
重新打開shell窗口，以普通用戶再次編譯
[solang@solang redis-6.0.1]$ make
Hint: It's a good idea to run 'make test' ;)

此次編譯成功。
若出現以下的錯誤，使用make MALLOC=libc進行編譯。

#include <jemalloc/jemalloc.h>

2.3make install
在redis根目錄下執行make install命令，此命令會將redis/src下的一些腳本拷貝到/usr/local/bin/目錄下，因爲/usr/local/bin/目錄已經在path環境變量中配置了，所以執行此命令的目的是在任何目錄下都可以直接啓動停止redis。
