centos 编译安装MYSQL8

需要高版本cmake和gcc

yum install cmake3 -y

yum -y install centos-release-scl
yum -y install devtoolset-8-gcc devtoolset-8-gcc-c++ devtoolset-8-binutils
scl enable devtoolset-8 bash

需要注意的是scl命令启用只是临时的，退出shell或重启就会恢复原系统gcc版本。
如果要长期使用gcc 8的话：

echo "source /opt/rh/devtoolset-8/enable" >>/etc/profile

/usr/bin/ 设置gcc编译器的软连接cc和c++

sudo ln -s /usr/local/bin/gcc /usr/bin/cc
sudo ln -s /usr/local/bin/g++ /usr/bin/c++
