篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了三十九安装PHP5安装PHP7相关的知识,希望对你有一定的参考价值。

一、安装php5

PHP官网www.php.net。主流版本5.6,7.1。

如果你的程序,PHP代码能用PHP7就用7,不能用就用5,PHP7的性能有很大提升。

# cd /usr/local/src/

# wget http://cn2.php.net/distributions/php-5.6.30.tar.gz

# tar zxvf php-5.6.30.tar.gz

# cd php-5.6.30  要进这个里面不然./configure会报没有那个文件

# ./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

解析:

--prefix=/usr/local/php  指定安装目录

--with-apxs2=/usr/local/apache2.4/bin/apxs    Apache的一个工具,它能让扩展模块自动的放到Apache的modules目录里,并且在配置文件里加一行lodmodule,自动配置上,能httpd -M加载出来这个模块。能帮你自动配置扩展模块。

--with-config-file-path=/usr/local/php/etc 指定配置文件所在路径,PHP的配置文件叫php.ini


--with-mysql=/usr/local/mysql  指定mysql的路径,三种不同的mysql驱动,或者是指定它的库,就好比需要识别网卡的驱动。老版本用这条

--with-pdo-mysql=/usr/local/mysql

--with-mysqli=/usr/local/mysql/bin/mysql_config 新版本用mysqli


--with-libxml-dir 后续的这些都是指定PHP所需要的一些模块,没有特殊要求就按照这些编译即可。

--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前要先安装mysql和Apache,因为这里的参数要指向他们。

输完该命令后,反馈有一条错误:

看到这些,表示这步已经执行成功了,也可以echo $?看一下

     现在已经知道是需要安装哪些包了,下次安装时就可以一次直接安装这7个包再执行./configure的命令

# make && make install

make install后,可以看到有:

chmod 755 /usr/local/apache2.4/modules/libphp5.so    把libphp5.so放到modules下

[activating module `php5' in /usr/local/apache2.4/conf/httpd.conf]   激活这个配置文件


# ls /usr/local/php

bin  etc  include  lib  php

[[email protected] php-5.6.30]# ls /usr/local/php/bin   核心的二进制文件在bin下

pear  peardev  pecl  phar  phar.phar  php  php-cgi  php-config  phpize

# du -sh /usr/local/apache2.4/modules/libphp5.so 这个文件就是我们想要的扩展模块

37M /usr/local/apache2.4/modules/libphp5.so

Apache和PHP结合是通过这个文件实现的。

# /usr/local/php/bin/php -m查看这个PHP加载了哪些模块,和httpd -M类似。

PHP不需要像Apache和mysql那样用start启动,因为它是作为Apache的一个模块存在的,如果libphp5.so这个文件删除,那Apache就不支持PHP了。需要执行PHP时就要用到php module。

PHP模块文件:/usr/local/apache2.4/modules/libphp5.so

# cp php.ini-production /usr/local/php/etc/php.ini

PHP的参考配置文件:php.ini-production

php.ini-production 生产环境使用

php.ini-development  开发环境

后面配置文件的路径,放这里是因为前面编译的时候指定的这里。

# /usr/local/php/bin/php -i |less

-i:该选项能查看到PHP的信息,编译参数,configuration file的路径(配置文件)

这行它要识别的名字是php.ini,拷贝过来以后才有。


二、安装PHP7

# cd /usr/local/src

# wget http://cn2.php.net/distributions/php-7.1.6.tar.bz2

# tar jxf php-7.1.6.tar.bz2

# cd 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

--with-mysql=/usr/local/mysql少了这一个参数,其他都一样。

# make && make install

    一台机器可以装2个PHP,但是Apache调用的PHP要指定好,就是配置文件修改。

# ls /usr/local/apache2.4/modules/libphp 可以看到有两个php模块文件

libphp5.so  libphp7.so

# /usr/local/apache2.4/bin/apachectl -M  查看到阿帕奇加载php5和php7两个。

php5_module (shared)

php7_module (shared)

# vim /usr/local/apache2.4/conf/httpd.conf  想用哪个就进配置文件改,不用哪个就在行首加个#注释掉

#LoadModule php5_module        modules/libphp5.so   进文件直接/php5就可以搜到了

LoadModule php7_module        modules/libphp7.so
