PHP5安装
PHP官网www.php.net
当前主流版本为5.6/7.1
进入存储源码包的目录：
[root@gary-tao ~]# cd /usr/local/src
下载php的源码包：
地址：wget http://cn2.php.net/distributions/php-5.6.30.tar.gz
5.解压压缩包：
[root@gary-tao src]# tar -zxvf php-5.6.30.tar.gz
6.进入安装目录：
[root@gary-tao src]# cd php-5.6.30[root@gary-tao php-5.6.30]#
7.安装php：
[root@gary-tao php-5.6.30]# ./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2.4/bin/apxs --with-config-file-path=/usr/local/php/etc --with-mysql=/usr/local/mysql --with-pdo-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-bz2 --with-openssl --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-mbstring --enable-sockets --enable-exif //安装PHP[root@gary-tao php-5.6.30]# echo $? //安装完成没有错误用这个检查
解释说明个别参数：
--prefix：指定安装目录。 --with-apxs2：Apache的工具，指定工具的地址，可以帮我们自动配置一些模块,不用人工干涉。 --with-config-file-path：指定配置文件的路径。 --with-mysql：指定mysql路径。
安装报错：
缺少libxml2这个库，安装命令：yum install -y libxml2-devel
缺少openssl库，安装命令：yum install -y openssl-devel
缺少bzip2包，安装命令：yum install -y bzip2-devel
缺少jpeglid包,安装命令：yum install -y libjpeg-devel
缺少libpng包，安装命令：yum install -y libpng-devel
缺少freetype包，安装命令:yum install -y freetype-devel
缺少libmcrypt包，安装命令：yum install -y libmcrypt-devel，如果你没有安装epel-release这个扩展源，就需要先安装这个扩展源，因为libmcrypt是在这个扩展源里面，安装扩展源命令：yum install -y epel-release
8.编译安装
[root@gary-tao php-5.6.30]# make [root@gary-tao php-5.6.30]# make install [root@gary-tao php-5.6.30]# echo $? 0
备注：Apache和php结合的通过图中的libphp5.so模块
9.查看php加载的模块（都是静态的）：
[root@gary-tao php-5.6.30]# /usr/local/php/bin/php -m [PHP Modules] bz2 Core ctype date dom ereg exif fileinfo filter gd hash iconv json libxml mbstring mcrypt mysql mysqli openssl pcre PDO pdo_mysql pdo_sqlite Phar posix Reflection session SimpleXML soap sockets SPL sqlite3 standard tokenizer xml xmlreader xmlwriter zlib [Zend Modules]
10.PHP是做为apache的模块存在，查看模块：
[root@gary-tao php-5.6.30]# /usr/local/apache2.4/bin/httpd -M AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 218.93.250.18. Set the 'ServerName' directive globally to suppress this message Loaded Modules: core_module (static) so_module (static) http_module (static) mpm_event_module (static) authn_file_module (shared) authn_core_module (shared) authz_host_module (shared) authz_groupfile_module (shared) authz_user_module (shared) authz_core_module (shared) access_compat_module (shared) auth_basic_module (shared) reqtimeout_module (shared) filter_module (shared) mime_module (shared) log_config_module (shared) env_module (shared) headers_module (shared) setenvif_module (shared) version_module (shared) unixd_module (shared) status_module (shared) autoindex_module (shared) dir_module (shared) alias_module (shared) php5_module (shared) [root@gary-tao php-5.6.30]# ls -l /usr/local/apache2.4/modules/libphp5.so //模块文件 -rwxr-xr-x 1 root root 37752872 12月 18 17:09 /usr/local/apache2.4/modules/libphp5.so
解释说明：
php5_module (shared)：这个说明PHP是作为httpd扩展模块的形式存在的,那如果apache要想执行php的脚本，它就需要依赖借助于这个模块文件，如果把这个.so文件删除，那apache就不支持php了，这个模块非常重要。
11.这个httpd的配置文件里就多了一行php模块，被注释掉的就是没有用的模块，如果想用，把#号去掉就可以了，随用随取：
[root@gary-tao php-5.6.30]# vim /usr/local/apache2.4/conf/httpd.conf //这是apache的配置文件
12.把php的参考配置文件复制到php的配置文件目录下：
示例如下：
[root@gary-tao php-5.6.30]# /usr/local/php/bin/php -i |less //查看php的一些配置信息，包括编译参数。 phpinfo() PHP Version => 5.6.30 System => Linux gary-tao 3.10.0-514.el7.x86_64 #1 SMP Tue Nov 22 16:42:41 UTC 2016 x86_64 Build Date => Dec 18 2017 17:05:31 Configure Command => './configure' '--prefix=/usr/local/php' '--with-apxs2=/usr/local/apache2.4/bin/apxs' '--with-config-file-path=/usr/local/php/etc' '--with-mysql=/usr/local/mysql' '--with-pdo-mysql=/usr/local/mysql' '--with-mysqli=/usr/local/mysql/bin/mysql_config' '--with-libxml-dir' '--with-gd' '--with-jpeg-dir' '--with-png-dir' '--with-freetype-dir' '--with-iconv-dir' '--with-zlib-dir' '--with-bz2' '--with-openssl' '--with-mcrypt' '--enable-soap' '--enable-gd-native-ttf' '--enable-mbstring' '--enable-sockets' '--enable-exif' Server API => Command Line Interface Virtual Directory Support => enabled Configuration File (php.ini) Path => /usr/local/php/etc Loaded Configuration File => (none) Scan this dir for additional .ini files => (none) Additional .ini files parsed => (none) PHP API => 20131106 PHP Extension => 20131226 Zend Extension => 220131226 Zend Extension Build => API220131226,TS PHP Extension Build => API20131226,TS Debug Build => no Thread Safety => enabled Zend Signal Handling => disabled Zend Memory Manager => enabled Zend Multibyte Support => provided by mbstring IPv6 Support => enabled DTrace Support => disabled Registered PHP Streams => https, ftps, compress.zlib, compress.bzip2, php, file, glob, data, http, ftp, phar Registered Stream Socket Transports => tcp, udp, unix, udg, ssl, sslv3, tls, tlsv1.0, tlsv1.1, tlsv1.2 Registered Stream Filters => zlib.*, bzip2.*, convert.iconv.*, mcrypt.*, mdecrypt.*, string.rot13, string.toupper, string.tolower, string.strip_tags, convert.*, consumed, dechunk This program makes use of the Zend Scripting Language Engine: Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies _______________________________________________________________________ Configuration bz2 [root@gary-tao php-5.6.30]# ls /usr/local/php/etc //查看模块下有没php.ini文件 pear.conf [root@gary-tao php-5.6.30]# cp php.ini-production /usr/local/php/etc/php.ini //需要到源码包的参考文件复制到php的配置文件目录下 [root@gary-tao php-5.6.30]# /usr/local/php/bin/php -i |less //查看php.ini是否有加载php.ini文件模块，如下图
PHP7安装
进入源码包的目录：
[root@gary-tao ~]# cd /usr/local/src/
2.下载源码包：
地址：wget http://cn2.php.net/distributions/php-7.1.6.tar.bz2
3.解压压缩包：
[root@gary-tao src]# tar jxvf php-7.1.6.tar.bz2
备注：如果没有安装bzip2压缩工具，请安装：yum install -y bzip2
4.进入目录：
[root@gary-tao src]# cd php-7.1.6[root@gary-tao php-7.1.6]#
5.安装php7：
[root@gary-tao php-7.1.6]# ./configure --prefix=/usr/local/php7 --with-apxs2=/usr/local/apache2.4/bin/apxs --with-config-file-path=/usr/local/php7/etc --with-pdo-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-bz2 --with-openssl --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-mbstring --enable-sockets --enable-exif
6.编译安装：
[root@gary-tao php-7.1.6]# make[root@gary-tao php-7.1.6]# make install
7.php7模块路径：
[root@gary-tao php-7.1.6]# ls /usr/local/apache2.4/modules/libphp7.so/usr/local/apache2.4/modules/libphp7.so
8.查看php7加载的模块（静态）：
[root@gary-tao php-7.1.6]# /usr/local/php7/bin/php -m[PHP Modules]bz2CorectypedatedomexiffileinfofiltergdhashiconvjsonlibxmlmbstringmcryptmysqliopensslpcrePDOpdo_mysqlpdo_sqlitePharposixReflectionsessionSimpleXMLsoapsocketsSPLsqlite3standardtokenizerxmlxmlreaderxmlwriterzlib[Zend Modules]
9.查看apache加载了几个php,通过修改配置文件来指定使用php5还是php7模块，不要的就注释掉：
示例如下：
[root@gary-tao php-7.1.6]# /usr/local/apache2.4/bin/apachectl -MAH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 218.93.250.18. Set the 'ServerName' directive globally to suppress this messageLoaded Modules: core_module (static) so_module (static) http_module (static) mpm_event_module (static) authn_file_module (shared) authn_core_module (shared) authz_host_module (shared) authz_groupfile_module (shared) authz_user_module (shared) authz_core_module (shared) access_compat_module (shared) auth_basic_module (shared) reqtimeout_module (shared) filter_module (shared) mime_module (shared) log_config_module (shared) env_module (shared) headers_module (shared) setenvif_module (shared) version_module (shared) unixd_module (shared) status_module (shared) autoindex_module (shared) dir_module (shared) alias_module (shared) php5_module (shared) php7_module (shared)[root@gary-tao php-7.1.6]# vim /usr/local/apache2.4/conf/httpd.conf
10.把php7的参考配置文件复制到php7的配置文件目录下：
[root@gary-tao php-7.1.6]# cp php.ini-production /usr/local/php7/etc/php.ini
