CentOS7最小安装mysql

CentOS7最小安装mysql


1.安装CentOS-7-x86_64-DVD-1511.iso。
  最小安装方式。建议添加开发工具，samba和文件共享。
  安装的时候选择静态IP地址，录入机器名


2.安装网络工具包
  yum install net-tools


  如果安装时为动态IP方式，则需要手工修改IP地址为静态，同时修改主机名


3.安装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.更新或升级最小化安装的 CentOS
  yum update && yum upgrade


5.添加163镜像源
  #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.安装mysql
  sudo rpm -Uvh mysql57-community-release-el7-9.noarch.rpm
  sudo yum install mysql-community-server
  vi /etc/my.cnf
