Linux switching multiple versions of Php____linux

Install the paths of each version of PHP plus the version number

such as--prefix=/usr/local/php-7.0.1

As below, I install the path

When installing, add each version of PHP-FPM to the service

Install-v-m755/php Source Path/sapi/fpm/init.d.php-fpm/etc/init.d/php-fpm (corresponding version number)

The easiest way to switch is to start a different service.

Turn off the corresponding T version of PHP-FPM first.

sudo service php-fpmxxxx stop

Turn on the version you want to switch

sudo service php-fpm7.0.5 start

The second way to use the script to switch

Copy a php-fpm startup script

sudo cp/etc/init.d/php-fpm7.0.5/etc/init.d/php-fpm

Use Vim to open, change prefix to prefix=/usr/local/php

The main thing here is to make a shortcut to the version of PHP that was launched.

Create a new script in the home directory switchphp.sh

#!/bin/zsh

version= ($ ls/usr/local | grep  php-| awk ' {printf '%s ', '} '))

echo $version
echo "Please enter the right version This number: "
i=1 for
ver in $version
does
    echo $i") "$ver
    i=$ (($i + 1))
done

Read num case

" $ Num "
	in [1234])
		echo the version you selected is: $version [$num]
		service php-fpm stop
		ln-sf/usr/local/$version [$num ]/usr/local/php
		If ["$?"!= 0]; then
			echo "has no permissions failed"
			exit 1
		fi
		service php-fpm start

		If ["$?"!= 0]; Then
			echo "No permissions Failed"
			exit 1
		fi

		echo "successfully switched"
	;;

	*
		Echo-n "The version number you entered is not correct. "
	;;

Esac

Version= ($ (ls/usr/local | grep  php-| awk ' {printf '%s ', $} ')

Pay attention to this sentence, according to the existing installation directory to modify

Modify the switchphp.sh into an executable file

sudo chmod 755 switchphp.sh

And then execute

sudo./switchphp.sh

The effect chart is as follows:
