• remove

  先删除依赖mysql，apache的包，mcrypt和libmcrypt-dev是系统包，不删除
  apt autoremove --purge libapache2-mod-php7.0 -y
  ls /etc/apache2/mods-enabled/php*
  dpkg -l | grep libapache2
  ls /usr/lib/apache2/modules/libphp7.0.so
  执行命令均未发现残余
  apt autoremove --purge php7.0-mysql -y
  执行命令均未发现残余
  删除php
  apt autoremove --purge php-common -y
  ls /usr/lib/php
      ls: cannot access '/usr/lib/php': No such file or directory
  find /etc -name "*php*"
      /etc/php
