Ubuntu 16.04搭建php5.6 Web服务器环境

Ubuntu 16.04默认安装php7.0环境，但是php7目前兼容性并不是很好，如果自行安装php5需要清除php7的已安装包，否则会报错。

移除默认及已安装的PHP包

  sudo dpkg -l | grep php| awk '{print $2}' |tr "\n" " "
  sudo apt-get install aptitude
  sudo aptitude purge `dpkg -l | grep php| awk '{print $2}' |tr "\n" " "`

添加 PPA

sudo add-apt-repository ppa:ondrej/php

安装php5.6

  sudo apt-get update
  sudo apt-get install php5.6

安装扩展

  sudo apt-get install php5.6-gd
  sudo apt-get install php5.6-mysql

安装Apache2

  sudo apt install apache2
  sudo apt-get install libapache2-mod-php5.6

安装MySQL

  sudo apt install mysql-server php5.6-mysql    root root0x0
  sudo apt-get install mysql-client
  mysql_secure_installation

安 phpmyadmin

  sudo apt-get install phpmyadmin
  sudo apt-get install php5.6-mbstring
  sudo apt-get install php5.6-gettext
  sudo ln -s /usr/share/phpmyadmin /var/www/html/phpmyadmin

配置phpmyadmin

  nano /etc/php/5.6/apache2/php.ini
  display_errors = On(显示错误日志，出现两次，都要改，不然无效)
  extension=php_mbstring.dll (开启mbstring)
  sudo dpkg-reconfigure phpmyadmin (重新配置phpmyadmin)
