1.安裝CentOS-7-x86_64-DVD-1511.iso。
最小安裝方式。建議添加開發工具，samba和文件共享。
安裝的時候選擇靜態IP地址，錄入機器名
2.安裝網絡工具包
yum install net-tools
如果安裝時爲動態IP方式，則需要手工修改IP地址爲靜態，同時修改主機名
3.安裝vmtools
mount -t auto /dev/cdrom /mnt/cdrom
cp /mnt/cdrom/VMwareTools-10.0.10-4301679.tar.gz /root
tar zxvf VMwareTools-10.0.10-4301679.tar.gz
cd vmware-tools-distrib
./vmware-install.pl
rm -rf vmware-tools-distrib
4.更新或升級最小化安裝的 CentOS
yum update && yum upgrade
5.添加163鏡像源
#mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
cd /etc/yum.repos.d/
wget http://mirrors.163.com/.help/CentOS7-Base-163.repo
yum clean all
yum makecache
5.安裝mysql
sudo rpm -Uvh mysql57-community-release-el7-9.noarch.rpm
sudo yum install mysql-community-server
vi /etc/my.cnf
