debian安裝php
不知道你問的linux，是哪個發行版本，常用的如 ubntu,centos,debian等。
我列一個centos7(伺服器常用這個版本)的安裝方法吧
centos7默認使用yum install 來安裝程序，但默認源安裝的php是5.4的，版本比較低，
要安裝高版本的，要麼下載源代碼手動編譯安裝，但對不熟悉的，萬一出點錯誤，會越搞越亂。我一般使用epel源安裝php，裡面各個版本都有，最新的php7.3
首先安裝epel
rpm -ivh http://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-7-11.noarch.rpm
這裡面的url是目前我用的，如果提示出錯，就是換url了，可以在電腦上手動打開epel源列表去檢查 epel-release是哪個版本，換上對應的名字
按版本安裝php
rpm-Uvhhttps://mirror.webtatic.com/yum/el7/webtatic-release.rpm
yuminstallphp56wphp56w-mysqlphp56w-pdophp56w-gdphp56w-sslphp56w-mbstringphp56w-cliphp56w-xmlphp56w-bcmath
我這里列的是一些常用的php擴展，如果需要其它的，手動加上即可
如果需要安裝php其它版本，把包名里的56改成對應版本即可 ,如
yuminstallphp71wphp71w-mysqlphp71w-pdophp71w-gdphp71w-sslphp71w-mbstringphp71w-cliphp71w-xmlphp71w-bcmath
yuminstallphp72wphp72w-mysqlphp72w-pdophp72w-gdphp72w-sslphp72w-mbstringphp72w-cliphp72w-xmlphp72w-bcmath
可對應安裝php7.1和php7.2，這種安裝方法，會默認配置好對應的設置，php.ini在/etc/中查找，命令行也默認啟用了 (php-cli)
❷ 如何在linux下安裝多個不同版本的PHP
Linux (測試環境 Ubuntu 12.04 Server X86_64)
1. 安裝編譯工具及所需類庫
$ 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. 安裝MySQL
$ sudo apt-get install mysql-server libmysqlclient-dev
3. 安裝PHP
Linux下多版本PHP共存需要自己手工編譯安裝。
下載PHP源文件到/opt/src目錄
$ 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
創建PHP各版本安裝目錄
$ mkdir -p /opt/php/{5217,5328,5429,5514}
安裝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
安裝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

安裝PHP 5.4.29
$ cd /opt/src
$ tar -xvjf php-5.4.29.tar.bz2
$ cd php-5.4.29
$ ./configure --prefix=/opt/php/5429 --with-config-file-scan-dir=/opt/php/5429/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 --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

$ cp php.ini-development /opt/php/5429/lib/php.ini
安裝PHP 5.5.14
$ 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. 安裝Apache
$ sudo apt-get install apache2
啟用相應模塊
$ a2enmod headers
$ a2enmod expires
$ a2enmod actions
$ a2enmod rewrite
5. 配置Apache
$ sudo vi /etc/apache2/httpd.conf
追加如下腳本映射和虛擬主機配置，原理同Windows的配置說明。
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>
# Virtualhosts

保存配置後，創建各站點的DocumentRoot目錄，再往每個目錄放置一個phpinfo的測試文件，完成後重啟Apache伺服器並在本地hosts文件加入域名解析，現在就可以訪問各站點來測試多版本PHP共存了。
好了，基本的多版本PHP共存解決方案已經完成，如果還需要添加其他的PHP類庫支持，後續自己再調用對應php目錄下的pecl, php_config等腳本編譯安裝就可以了。
❸ 在debian上安裝PHP時遇到的有關問題怎麼解決
用yum安裝軟體（自動解決依賴關系） YUM有以下特點：1、可以同時配置多個資源庫(Repository)2、簡潔的配置文件(/etc/yum.conf)3、自動解決增加或刪除rpm包時遇到的依賴性問題使用方便
❹ debian如何apt-get安裝php5.4
sudoapt-getinstallphp5
❺ debian 默認web伺服器包含php么
不包含，debian安裝php太簡單了。
❻ debian nginx php應該放在哪個目錄
這個沒有規定， 默認安裝是在 /usr/bin下面， 這樣就不用加入到系統的PATH, LIB
如果是自己編譯，一般會是/usr/local/phpxx, 編譯完成之後， 設置當前用戶或者系統的PATH

備註：錯誤1：Cannot find OpenSSL's libraries 解決：
確認已安裝過 openssl、libssl-dev 包，還是會提示該錯誤；解決辦法：
root@test2:~/php-5.3.27# find / -name libssl.so輸出結果為： /usr/lib/x86_64-Linux-gnu/libssl.so初步判斷它可能只會在 /usr/lib/ 下尋找 libssl.so 文件，於是：
ln -s /usr/lib/x86_64-linux-gnu/libssl.so /usr/lib錯誤2：debian Please reinstall the libcurl distribution 解決：
# RetHat CentOS or Fedora 使用下面安裝命令yum install curl curl-devel
# Debian or Ubuntu使用下面的安裝命令
apt-get install curl
apt-get install libcurl4-gnutls-dev
錯誤3：Unable to locate gmp.h 解決：
在https://launchpad.net/debian/+source/gmp 下載 gmp源碼包，接著 ./configure && make && make install編譯 安裝
make &&make install
報錯處理
