先去官網（https://dev.mysql.com/downloads/mysql/），在Select Operating System選擇Red Hat Enterprise Linux / Oracle Linux，在Select OS Version選擇Red Hat Enterprise Linux 6 / Oracle Linux 6 (x86, 64-bit)，下載RPM Bundle
        將下載的檔案上傳到伺服器/usr/local下，接著執行如下命令

rpm -qa|grep mysql #檢視mysql是否安裝，如果已經安裝需要解除安裝，如果是
yum -y
 
 remove mysql-libs-5.1.71-1.el6.x86_64 
 #解除安裝
cd /usr/local/ #指定目錄
tar -xvf mysql-5.7.18-1.el6.x86_64.rpm-bundle.tar
 #解壓
rpm -ivh mysql-community-common-5.7.18-1.el6.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.18-1.el6.x86_64.rpm
rpm -ivh mysql-community-client-5.7.18-1.el6.x86_64.rpm
yum install perl #安裝server時需要的依賴包
 

yum install numactl #安裝server時需要的依賴包
yum install libaio #安裝時需要的依賴包
rpm -ivh mysql-community-server-5.7.18-1.el6.x86_64.rpm
service mysqld start #啟動mysqld服務
netstat -tlunp #檢視服務所需埠
cat /var/log/mysqld.log | more #檢視日誌，找初始密碼
cat /etc/issue #檢視系統版本
getconf LONG_BIT #檢視系統位數

如下所示
