使用MySQL8无需像MySQL5那样需要Boost依赖，和经过35-55分钟的等待编译完成，直接解压即可使用，方便快捷！
1，环境：
操作系统 CentOS Linux release 7.6.1810 (Core) 64位
服务器环境 “腾讯云”服务器
cat /etc/centos-release # 查看centos系统版本MySQL8.0.15源码包下载地址
2，执行以下命令，一键安装MySQL8
mkdir -p /data/soft/ # 创建安装目录
cd /data/soft/ # 打开安装目录
yum -y install wget gcc gcc-c++ ncurses ncurses-devel cmake numactl.x86_64 # 安装相应依赖库
wget https://downloads.mysql.com/archives/get/file/mysql-8.0.13-el7-x86_64.tar.gz
# 下载源码包
tar -zxvf /data/soft/mysql-8.0.15-el7-x86_64.tar.gz -C /data/soft # 解压源码包到安装目录
mv /data/soft/mysql-8.0.15-el7-x86_64/ /data/soft/mysql/ # 重命名安装目录
cd /data/soft/mysql/ # 打开安装目录
cp /data/soft/mysql/support-files/mysql.server /etc/init.d/mysql #添加到服务启动cat >/etc/my.cnf <<EOF # 配置mysql数据库
