使用ispconfig3和Ubuntu 18.04安装多个PHP版本(php5.6\php7.1\php7.3)

使用ispconfig3，我们可以管理和安装多个PHP版本以映射这些单独的站点。在这里，我向您展示了最简单的方法。

以下所有命令均使用 root 权限！

第一步：更新系统

apt-get update
apt-get upgrade

第二步：将Sury.org添加到source.list

apt-get install apt-transport-https lsb-release ca-certificates
add-apt-repository ppa:ondrej/php
apt-get update
apt-get upgrade

第三步：安装PHP版本

PHP 5.6:

apt-get -y install php5.6 php5.6-common php5.6-fpm php5.6-gd php5.6-mysql php5.6-imap php5.6-cli php5.6-cgi php-pear php5.6-mcrypt php5.6-curl php5.6-intl php5.6-pspell php5.6-recode php5.6-sqlite3 php5.6-tidy php5.6-xmlrpc php5.6-xsl php-memcache php-imagick php-gettext php5.6-zip php5.6-mbstring php5.6-soap php5.6-common php5.6-opcache php5.6-mysql

PHP 7.0

apt-get -y install php7.0 php7.0-common php7.0-fpm php7.0-gd php7.0-mysql php7.0-imap php7.0-cli php7.0-cgi php-pear php7.0-mcrypt php7.0-curl php7.0-intl php7.0-pspell php7.0-recode php7.0-sqlite3 php7.0-tidy php7.0-xmlrpc php7.0-xsl php-memcache php-imagick php-gettext php7.0-zip php7.0-mbstring php7.0-soap php7.0-common php7.0-opcache php7.0-mysql

PHP 7.1

apt-get -y install php7.1 php7.1-common php7.1-fpm php7.1-gd php7.1-mysql php7.1-imap php7.1-cli php7.1-cgi php-pear php7.1-mcrypt php7.1-curl php7.1-intl php7.1-pspell php7.1-recode php7.1-sqlite3 php7.1-tidy php7.1-xmlrpc php7.1-xsl php-memcache php-imagick php-gettext php7.1-zip php7.1-mbstring php7.1-soap php7.1-common php7.1-opcache php7.1-mysql

PHP 7.2

apt-get -y install php7.2 php7.2-common php7.2-fpm php7.2-gd php7.2-mysql php7.2-imap php7.2-cli php7.2-cgi php-pear php7.2-curl php7.2-intl php7.2-pspell php7.2-recode php7.2-sqlite3 php7.2-tidy php7.2-xmlrpc php7.2-xsl php-memcache php-imagick php-gettext php7.2-zip php7.2-mbstring php7.2-soap php7.2-common php7.2-opcache php7.2-mysql

PHP 7.3

apt-get -y install php7.3 php7.3-common php7.3-fpm php7.3-gd php7.3-mysql php7.3-imap php7.3-cli php7.3-cgi php-pear php7.3-curl php7.3-intl php7.3-pspell php7.3-recode php7.3-sqlite3 php7.3-tidy php7.3-xmlrpc php7.3-xsl php-memcache php-imagick php-gettext php7.3-zip php7.3-mbstring php7.3-soap php7.3-common php7.3-opcache php7.3-mysql

第四步：在Ubuntu中将PHP重置为默认值（必须）

通过安装新的PHP软件包，Ubuntu中的默认PHP版本已更改为最新的PHP版本。这可能会导致某些应用程序出现问题，因此我们将其重置为默认值。

对于Ubuntu 18.04，我们选择：PHP 7.2

同时执行两个命令，并将两者都设置为DEFAULT：

update-alternatives --config php
update-alternatives --config php-cgi

注意：为什么这个步骤是必须的？是因为不操作，会导致后期虽然修改了php.ini的值，但是仍然不起作用！

第五步：在ispconfig3中设置

进入ISPconfig控制面板， 我们在其中添加以下内容：“添加新的PHP版本”：

PHP Name：（自己命名，建议以php版本命名，例如：php5.6）

PHP 5.6

标签“ FastCGI Setting”

PHP FastCGI Binary的路径： php5.6-cgi

php.ini目录的路径： /etc/php/5.6/cgi/php.ini

标签“ FPM Setting”

PHP-FPM初始化脚本的路径： php5.6-fpm

php.ini目录的路径： /etc/php/5.6/fpm/php.ini

PHP-FPM池目录的路径： /etc/php/5.6/fpm/pool.d

PHP 7.0

Tab “Name”Server: Select the server hereName: Give a name here

Tab “FastCGI Settings”

Path to PHP FastCGI Binary: php7.0-cgi

Path to the php.ini directory: /etc/php/7.0/cgi/php.ini

Tab “FPM Settings”

Path to PHP-FPM init Script: php7.0-fpm

第六步：重启

最后一步，重启下面服务：

systemctl restart php5.6-fpm
systemctl restart php7.0-fpm
systemctl restart php7.1-fpm
systemctl restart php7.2-fpm
systemctl restart php7.3-fpm
systemctl restart apache2
