Ubuntu16.04怎么搭建php5.6Web服务器环境

这篇文章将为大家详细讲解有关Ubuntu16.04怎么搭建php5.6Web服务器环境，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。

Ubuntu 16.04默认安装php7.0环境，但是php7目前对某些旧系统的兼容性并不是很好，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 aptitudesudo 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 updatesudo apt-get install php5.6

安装扩展

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

安装Apache2

sudo apt install apache2sudo apt-get install libapache2-mod-php5.6

安装MySQL

sudo apt install mysql-server php5.6-mysql  root root0x0sudo apt-get install mysql-clientmysql_secure_installation

安装 phpmyadmin

sudo apt-get install phpmyadminsudo apt-get install php5.6-mbstringsudo apt-get install php5.6-gettextsudo ln -s /usr/share/phpmyadmin /var/www/html/phpmyadmin

配置phpmyadmin

nano /etc/php/5.6/apache2/php.inidisplay_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)

增加网站

sudo ln -s /etc/apache2/sites-available/files.conf /etc/apache2/sites-enabled/files.confsudo chown -R www-data /var/www/tianyasudo /etc/init.d/apache2 restart

添加FTP
