CentOS环境下安装Redis，make时报错？
MAKE hiredis
cd hiredis && make static
make[3]: Entering directory `/home/zzb/soft/redis-5.0.3/deps/hiredis'
gcc -std=c99 -pedantic -c -O3 -fPIC -Wall -W -Wstrict-prototypes -Wwrite-strings

make[2]: *** [hiredis] 错误 2
make[2]: Leaving directory `/home/zzb/soft/redis-5.0.3/deps'
make[1]: [persist-settings] 错误 2 (忽略)
CC adlist.o

make[1]: *** [adlist.o] 错误 127
make[1]: Leaving directory `/home/zzb/soft/redis-5.0.3/src'
make: *** [all] 错误 2
[root@server4 redis-5.0.3]#
解决方案一： 因为gcc依赖很多，以下按顺序都执行一下：
yum install cpp
yum install binutils
yum install glibc
yum install glibc-kernheaders
yum install glibc-common
yum install glibc-devel
yum install gcc
yum install make
然后，删除redis解压文件，重新解压。在执行make。
Hint: It's a good idea to run 'make test' ;)

......redis-server
redis-cli
出现服务端和客户端文件表明安装成功。
测试：

解决方案二：
https://blog.csdn.net/weixin_40493969/article/details/81150469
出现如下错误 :
cd src && make all
make[1]: Entering directory '/xx/xx/redis-x.x.x/src'
CC adlist.o
/bin/sh: cc: command not found
make[1]: *** [adlist.o] Error 127
make[1]: Leaving directory '/xx/xx/redis-x.x.x/src'
make: *** [all] Error 2
1、先查看是否安装c++的编译器； 执行 yum -y install gcc-c++
安装完c++编译器后 再次 make 若报此错
出现如下错误：
cd src && make all
make[1]: Entering directory '/xx/xx/redis-x.x.x/src'
LINK redis-server
cc: ../deps/hiredis/libhiredis.a: No such file or directory
cc: ../deps/lua/src/liblua.a: No such file or directory
make[1]: *** [redis-server] Error 1
make[1]: Leaving directory '/xx/xx/redis-x.x.x/src'
make: *** [all] Error 2
2、执行 make clean 后再次 执行 make ，再检查redis-x.x.x/src 目录下有没有 redis-server、redis-cli 和 /usr/local/bin下有没有
若无，则把redis-x.x.x 文件夹删掉，再解压一次redis的压缩包，cd进入 redis-x.x.x 中， make 一下 即可
即解决安装redis时 ， 在执行 make 时报错的问题
