1.redis6.0安裝報錯

2.報錯原因

gcc得版本問題，新版本redis6.0

# 查看gcc版本
gcc -v

3.解決辦法

#升級到 5.3及以上版本
yum -y install centos-release-scl
yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils
 
scl enable devtoolset-9 bash
 
#注意：scl命令啟用只是臨時的，推出xshell或者重啟就會恢復到原來的gcc版本。
#如果要長期生效的話，執行如下：
echo "source /opt/rh/devtoolset-9/enable" >>/etc/profile
