debian安装php
不知道你问的linux，是哪个发行版本，常用的如 ubntu,centos,debian等。
我列一个centos7(服务器常用这个版本)的安装方法吧
centos7默认使用yum install 来安装程序，但默认源安装的php是5.4的，版本比较低，
要安装高版本的，要么下载源代码手动编译安装，但对不熟悉的，万一出点错误，会越搞越乱。我一般使用epel源安装php，里面各个版本都有，最新的php7.3
首先安装epel
rpm -ivh http://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-7-11.noarch.rpm
这里面的url是目前我用的，如果提示出错，就是换url了，可以在电脑上手动打开epel源列表去检查 epel-release是哪个版本，换上对应的名字
按版本安装php
rpm-Uvhhttps://mirror.webtatic.com/yum/el7/webtatic-release.rpm
yuminstallphp56wphp56w-mysqlphp56w-pdophp56w-gdphp56w-sslphp56w-mbstringphp56w-cliphp56w-xmlphp56w-bcmath
我这里列的是一些常用的php扩展，如果需要其它的，手动加上即可
如果需要安装php其它版本，把包名里的56改成对应版本即可 ,如
yuminstallphp71wphp71w-mysqlphp71w-pdophp71w-gdphp71w-sslphp71w-mbstringphp71w-cliphp71w-xmlphp71w-bcmath
yuminstallphp72wphp72w-mysqlphp72w-pdophp72w-gdphp72w-sslphp72w-mbstringphp72w-cliphp72w-xmlphp72w-bcmath
可对应安装php7.1和php7.2，这种安装方法，会默认配置好对应的设置，php.ini在/etc/中查找，命令行也默认启用了 (php-cli)
❷ 如何在linux下安装多个不同版本的PHP
Linux (测试环境 Ubuntu 12.04 Server X86_64)
1. 安装编译工具及所需类库
$ sudo apt-get install build-essential gcc g++ autoconf libjpeg62 libjpeg62-dev libpng12-0 libpng12-dev libfreetype6 libfreetype6-dev libxml2 libxml2-dev zlib1g zlib1g-dev bzip2 libbz2-dev openssl libssl-dev curl libcurl4-openssl-dev libpcre3 libpcre3-dev libevent-1.4-2 libevent-dev libmcrypt4 libmcrypt-dev mcrypt libltdl-dev libldap2-dev libsasl2-dev libmhash-dev libc-client2007e libc-client2007e-dev
2. 安装MySQL
$ sudo apt-get install mysql-server libmysqlclient-dev
3. 安装PHP
Linux下多版本PHP共存需要自己手工编译安装。
下载PHP源文件到/opt/src目录
$ mkdir /opt/src
$ cd /opt/src
$ wget http://museum.php.net/php5/php-5.2.17.tar.bz2 -O php-5.2.17.tar.bz2
$ wget http://cn2.php.net/get/php-5.3.28.tar.bz2/from/this/mirror -O php-5.3.28.tar.bz2
$ wget http://cn2.php.net/get/php-5.4.29.tar.bz2/from/this/mirror -O php-5.4.29.tar.bz2
$ wget http://cn2.php.net/get/php-5.5.14.tar.bz2/from/this/mirror -O php-5.5.14.tar.bz2
创建PHP各版本安装目录
$ mkdir -p /opt/php/{5217,5328,5429,5514}
安装PHP 5.2.17
$ cd /opt/src
$ tar -xvjf php-5.2.17.tar.bz2
$ cd php-5.2.17
$ sudo ln -s /usr/lib/x86_64-linux-gnu/libjpeg.so /usr/lib/libjpeg.so
$ sudo ln -s /usr/lib/x86_64-linux-gnu/libpng.so /usr/lib/libpng.so
$ sudo ln -s /usr/lib/x86_64-linux-gnu/libkrb5.so /usr/lib/libkrb5.so
$ wget -O debian_patches_disable_SSLv2_for_openssl_1_0_0.patch “https://bugs.php.net/patch-display.php?bug_id=54736&patch=debian_patches...”
$ patch -p1 < debian_patches_disable_SSLv2_for_openssl_1_0_0.patch

$ make
$ sudo make install
$ cp php.ini-recommended /opt/php/5217/lib/php.ini
安装PHP 5.3.28
$ cd /opt/src
$ tar -xvjf php-5.3.28.tar.bz2
$ cd php-5.3.28
$ ./configure --prefix=/opt/php/5328 --with-config-file-scan-dir=/opt/php/5328/etc/php.d --with-mysql --with-pdo-mysql --with-mysqli --with-iconv-dir --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --enable-safe-mode --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers --enable-mbregex --enable-mbstring --with-mcrypt --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --enable-ftp --disable-debug --disable-ipv6 --disable-short-tags --enable-calendar --with-imap --with-imap-ssl --with-kerberos

$ cd /opt/src
$ tar -xvjf php-5.5.14.tar.bz2
$ cd php-5.5.14
$ ./configure --prefix=/opt/php/5514 --with-config-file-scan-dir=/opt/php/5514/etc/php.d --with-mysql --with-pdo-mysql --with-mysqli --with-iconv-dir --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-mbstring --with-mcrypt --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --enable-ftp --disable-debug --disable-ipv6 --disable-short-tags --enable-calendar --with-imap --with-imap-ssl --with-kerberos
$ make
$ sudo make install
$ cp php.ini-development /opt/php/5514/lib/php.ini
4. 安装Apache
$ sudo apt-get install apache2
启用相应模块
$ a2enmod headers
$ a2enmod expires
$ a2enmod actions
$ a2enmod rewrite
5. 配置Apache
$ sudo vi /etc/apache2/httpd.conf
追加如下脚本映射和虚拟主机配置，原理同Windows的配置说明。
ServerName localhost
AddType application/x-httpd-php .php
ScriptAlias /php-5217/ "/opt/php/5217/bin/"
ScriptAlias /php-5328/ "/opt/php/5328/bin/"
ScriptAlias /php-5429/ "/opt/php/5429/bin/"
ScriptAlias /php-5514/ "/opt/php/5514/bin/"
<Directory /var/www/sites>
Options Indexes FollowSymLinks Includes ExecCGI
DirectoryIndex index.php index.html
AllowOverride All
Order allow,deny
Allow from all
</Directory>
<Directory /var/www/sites/5217>
Action application/x-httpd-php "/php-5217/php-cgi"
</Directory>
<Directory /var/www/sites/5328>
Action application/x-httpd-php "/php-5328/php-cgi"
</Directory>
<Directory /var/www/sites/5429>

</Directory>
<Directory /var/www/sites/5514>
Action application/x-httpd-php "/php-5514/php-cgi"
</Directory>
# Virtualhosts
<VirtualHost *:80>
ServerAdmin [email protected]
DocumentRoot "/var/www/sites/5217/test.local"
ServerName php5217.local
ErrorLog "/var/log/apache2/php5217.local-error.log"
CustomLog "/var/log/apache2/php5217.local-access.log" common
</VirtualHost>

</VirtualHost>
保存配置后，创建各站点的DocumentRoot目录，再往每个目录放置一个phpinfo的测试文件，完成后重启Apache服务器并在本地hosts文件加入域名解析，现在就可以访问各站点来测试多版本PHP共存了。
好了，基本的多版本PHP共存解决方案已经完成，如果还需要添加其他的PHP类库支持，后续自己再调用对应php目录下的pecl, php_config等脚本编译安装就可以了。
❸ 在debian上安装PHP时遇到的有关问题怎么解决
用yum安装软件（自动解决依赖关系） YUM有以下特点：1、可以同时配置多个资源库(Repository)2、简洁的配置文件(/etc/yum.conf)3、自动解决增加或删除rpm包时遇到的依赖性问题使用方便
❹ debian如何apt-get安装php5.4
sudoapt-getinstallphp5
❺ debian 默认web服务器包含php么
不包含，debian安装php太简单了。
❻ debian nginx php应该放在哪个目录
这个没有规定， 默认安装是在 /usr/bin下面， 这样就不用加入到系统的PATH, LIB
如果是自己编译，一般会是/usr/local/phpxx, 编译完成之后， 设置当前用户或者系统的PATH

备注：错误1：Cannot find OpenSSL's libraries 解决：
确认已安装过 openssl、libssl-dev 包，还是会提示该错误；解决办法：
root@test2:~/php-5.3.27# find / -name libssl.so输出结果为： /usr/lib/x86_64-Linux-gnu/libssl.so初步判断它可能只会在 /usr/lib/ 下寻找 libssl.so 文件，于是：
ln -s /usr/lib/x86_64-linux-gnu/libssl.so /usr/lib错误2：debian Please reinstall the libcurl distribution 解决：
# RetHat CentOS or Fedora 使用下面安装命令yum install curl curl-devel
# Debian or Ubuntu使用下面的安装命令
apt-get install curl
apt-get install libcurl4-gnutls-dev
错误3：Unable to locate gmp.h 解决：
在https://launchpad.net/debian/+source/gmp 下载 gmp源码包，接着 ./configure && make && make install编译 安装
make &&make install
报错处理
