lamp安装php5.6版

Ubuntu 16.04 comes with PHP7 as the standard, so there are no PHP5 packages

However if you like you can add a PPA to get those packages anyways:

Remove all the stock php packages

List installed php packages with dpkg -l | grep php| awk ‘{print $2}’ |tr “\n” ” ” then remove unneeded packages with sudo aptitude purge your_packages_here or if you want to directly remove them all use :

sudo aptitude purge

dpkg -l | grep php| awk '{print $2}' |tr "\n" " "

Add the PPA

sudo add-apt-repository ppa:ondrej/php

Install your PHP Version

sudo apt-get update

sudo apt-get install php5.6

You can install php5.6 modules too ..

Verify your version

sudo php -v

install Apache2

1 sudo apt install apache2

2 sudo apt-get install libapache2-mod-php

install MySQL

1 sudo apt install mysql-server php5.6-mysql

2 sudo apt-get install mysql-client

3 mysql_secure_installation

install phpmyadmin

1 sudo apt-get install phpmyadmin

2 sudo apt-get install php5.6-mbstring

3 sudo apt-get install php5.6-gettext

4 sudo ln -s /usr/share/phpmyadmin /var/www/html/phpmyadmin

配置phpmyadmin
