目前主流的php版本是5.6和7.1。和php 5相比,php 7对于性能的提升的很大的,对于自身的处理速度优化了很多,同时也改变了一些语法的使用。但由于很多软件都是基于php 5的,因此php 5和7的安装和配置都要熟练掌握。
安装PHP 5
1、下载安装包
[root@juispan src]# wget http://cn2.php.net/distributions/php-5.6.30.tar.gz --2017-07-21 07:39:35-- http://cn2.php.net/distributions/php-5.6.30.tar.gz 正在解析主机 cn2.php.net (cn2.php.net)... 220.181.136.41, 220.181.136.30, 220.181.136.55, ... 正在连接 cn2.php.net (cn2.php.net)|220.181.136.41|:80... 已连接。 已发出 HTTP 请求,正在等待回应... 200 OK 长度:19274631 (18M) [application/x-gzip] 正在保存至: “php-5.6.30.tar.gz” 100%[==============================================>] 19,274,631 518KB/s 用时 34s 2017-07-21 07:40:10 (552 KB/s) - 已保存 “php-5.6.30.tar.gz” [19274631/19274631])
2、解压压缩包
[root@juispan src]# tar zxf php-5.6.30.tar.gz
3、配置php
[root@juispan src]# cd php-5.6.30 [root@juispan 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
在配置过程中,会遇到一个接一个的配置失败,这里需要耐心处理。
问题1:configure: error: xml2-config not found. Please check your libxml2 installation.
[root@juispan php-5.6.30]# yum install -y libxml2-devel
问题2:configure: error: Cannot find OpenSSL‘s <evp.h>
[root@juispan php-5.6.30]# yum install -y openssl-devel
问题3:configure: error: Please reinstall the BZip2 distribution
[root@juispan php-5.6.30]# yum install -y bzip2-devel
问题4:configure: error: jpeglib.h not found.
[root@juispan php-5.6.30]# yum install -y libjpeg-turbo-devel
问题5:configure: error: png.h not found.
[root@juispan php-5.6.30]# yum install -y libpng-devel
问题6:configure: error: freetype-config not found.
[root@juispan php-5.6.30]# yum install -y freetype-devel
问题7:configure: error: mcrypt.h not found. Please reinstall libmcrypt.
[root@juispan php-5.6.30]# yum install -y libmcrypt-devel
处理完以上问题后,重新配置出现以下文本:
Generating files configure: creating ./config.status creating main/internal_functions.c creating main/internal_functions_cli.c +--------------------------------------------------------------------+ | License: | | This software is subject to the PHP License, available in this | | distribution in the file LICENSE. By continuing this installation | | process, you are bound by the terms of this license agreement. | | If you do not agree with the terms of this license, you must abort | | the installation process at this point. | +--------------------------------------------------------------------+ Thank you for using PHP. config.status: creating php5.spec config.status: creating main/build-defs.h config.status: creating scripts/phpize config.status: creating scripts/man1/phpize.1 config.status: creating scripts/php-config config.status: creating scripts/man1/php-config.1 config.status: creating sapi/cli/php.1 config.status: creating sapi/cgi/php-cgi.1 config.status: creating ext/phar/phar.1 config.status: creating ext/phar/phar.phar.1 config.status: creating main/php_config.h config.status: executing default commands
以上文本内容表示配置成功,如果不放心可以用“echo $?”确认下。
4、编译与安装
[root@juispan php-5.6.30]# make &&make install [root@juispan php-5.6.30]# echo $? 0 [root@juispan php-5.6.30]# cp php.ini-production /usr/local/php/etc/php.ini
5、查看与验证
[root@juispan php-5.6.30]# du -sh /usr/local/apache2.4/modules/libphp5.so 37M /usr/local/apache2.4/modules/libphp5.so [root@juispan php-5.6.30]# cat /usr/local/apache2.4/conf/httpd.conf | grep -i php LoadModule php5_module modules/libphp5.so [root@juispan php-5.6.30]# /usr/local/apache2.4/bin/httpd -M | tail -1 php5_module (shared)
前几章说过,php在LAMP架构里的作用只是Apache用于与mysql之间通讯的桥梁。因此,只要apache2.4的modules文件里有libphp5.so文件,且在配置文件里有相应的配置即可。即使删除php的安装目录也不会有太大的影响。
安装PHP 7
1、下载安装包
[root@juispan php-5.6.30]# cd /usr/local/src [root@juispan src]# wget http://cn2.php.net/distributions/php-7.1.6.tar.bz2
2、解压压缩包
[root@juispan src]# tar jxf php-7.1.6.tar.bz2 tar (child): bzip2:无法 exec: 没有那个文件或目录 tar (child): Error is not recoverable: exiting now tar: Child returned status 2 tar: Error is not recoverable: exiting now [root@juispan src]# yum install -y bzip2 [root@juispan src]# tar jxf php-7.1.6.tar.bz2
3、配置php
[root@juispan src]# cd php-7.1.6 [root@juispan 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 [root@juispan php-7.1.6]# echo $? 0
4、编译与安装
[root@juispan php-7.1.6]# make &&make install [root@juispan php-7.1.6]# echo $? 0
5、查看与验证
[root@juispan php-7.1.6]# ls /usr/local/apache2.4/modules/libphp7.so /usr/local/apache2.4/modules/libphp7.so [root@juispan php-7.1.6]# cp php.ini-production /usr/local/php7/etc/php.ini [root@juispan php-7.1.6]# cat /usr/local/apache2.4/conf/httpd.conf | grep -i php LoadModule php5_module modules/libphp5.so LoadModule php7_module modules/libphp7.so [root@juispan php-7.1.6]# /usr/local/apache2.4/bin/httpd -M | tail -2 php5_module (shared) php7_module (shared)
