• #卸载mysql
  /etc/init.d/mysqld stop &> /dev/null
  killall mysqld &> /dev/null
  sudo rm -rf /mengdi/server/mysql &> /dev/null
  sudo rm -rf /mengdi/server/mysql-* &> /dev/null
  sudo rm -rf /mengdi/log/mysql &> /dev/null
  sudo rm -rf /etc/my.cnf
  sudo rm -f /etc/init.d/mysqld
  更改环境变量
  
  准备工作1，创建环境统一目录
  sudo mkdir /mengdi
  cd /mengdi
  sudo mkdir server
  sudo mkdir -p log/mysql
  
  准备工作2，创建mysql用户及组
  groupadd mysql
  useradd -g mysql -s /sbin/nologin mysql
  
  准备工作3，安装依赖
  apt-get -y update
  apt-get -y autoremove mysql-server
  apt-get -y install unzip build-essential libncurses5-dev libfreetype6-dev libxml2-dev libssl-dev libcurl4-openssl-dev libjpeg62-dev libpng12-dev libfreetype6-dev libsasl2-dev libpcre3-dev autoconf libperl-dev libtool libaio*
