在linux安装php

it2025-04-10  6

去www.php.net找下载最新的版本

http://www.php.net/downloads.php

下载解压

# 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

配置

#./configure --prefix=/usr/local/php \--with-curl \--with-freetype-dir \--with-gd \--with-gettext \--with-iconv-dir \--with-kerberos \--with-libdir=lib64 \--with-libxml-dir \--with-mysqli \

--with-jpeg-dir \

--with-openssl \

--with-pcre-regex \--with-pdo-mysql \--with-pdo-sqlite \--with-pear \--with-png-dir \--with-xmlrpc \--with-xsl \--with-zlib \--enable-fpm \--enable-bcmath \--enable-libxml \--enable-inline-optimization \--enable-gd-native-ttf \--enable-mbregex \--enable-mbstring \--enable-opcache \--enable-pcntl \--enable-shmop \--enable-soap \--enable-sockets \--enable-sysvsem \--enable-xml \--enable-zip

 

编译安装

配置成功后继续完成编译安装php

# make && make install 

2.cp ./sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm还可以做成服务

复制php-fpm文件到php安装目录

# cp -R ./sapi/fpm/php-fpm.conf /usr/local/php/etc/php-fpm.conf

 

拷贝php.ini文件

安装目录有2个文件:php.ini-development和php.ini-production

注意php.ini-production拥有较高的安全性设定,则适合上线当产品使用

# cp php.ini-development /usr/local/php/lib/php.ini

或者

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

 

如果遇到

-bash: /etc/init.d/php-fpm: Permission denied

解决方法 chmod 755 /etc/init.d/php-fpm

 

/etc/init.d/php-fpm start/sbin/chkconfig --add php-fpm (添加到开机服务列表)/sbin/chkconfig php-fpm on

 

linux下如何执行PHP脚本

为简化输入可把此php执行程序 copy 到系统命令目录下:

#cp /usr/local/php/bin/php /usr/sbin/

验证:输入以下命令,如正确获取 php 版本,说明操作成功。

#php -v

这样,以后再执行PHP脚本时可直接采用以下输入方式即可。

#php a.php

 

 

linux下为已经编译好的php环境添加mysql扩展(php安装完成后如何添加mysql扩展)

 

问题背景平常我们都是先安装mysql,然后才能去安装php。假如先安装php,后安装mysql,由于php需要连接mysql,因而在php引擎中需要配置使用mysql.so扩展。这时需要手动编译生成mysql.so扩展。解决方案使用phpize工具能够生成mysql.so,但是必须加上"--with-mysql=mysql客户端的路径"。也就是mysql.so模块必须用到mysql客户端才行。可以这样理解,mysql.so内部会调用mysql客户端,以便实现连接mysql数据库服务器。我们常常用到的mysql_connect()可能就是调用了mysql客户端才能完成连接数据库的操作。实践生成mysql.so的过程大体思路:需要用到php的源码包才行。通过源码包中提供的phpize文件(一个专门挂接php扩展的工具),phpize的规则:去哪个目录下运行phpize文件,那么就会在该目录下生成一个configure文件。具体的安装步骤如下php安装完成后添加mysql扩展基本步骤如下:

1、进入php源代码目录: [root@localhost /]# # cd cd /usr/local/php-5.3.28 2、再进入要添加的mysql扩展源码目录: [root@localhost php-5.3.28]cd ext/mysql/ [root@localhost mysql]# yum install autoconf (CentOS 5.4需安装) 3、调用已经编译好的php可执行程序phpize: [root@localhost mysql] /usr/local/php/bin/phpize 4、然后configure: [root@localhost mysql]# ./configure --with-php-config=/usr/local/php/bin/php-config --with-mysql=/usr/local/mysql/ --with-zlib-dir=/usr/local/lib 注意: /usr/local/mysql 为mysql的安装目录 /usr/local/lib/php/extensions/no-debug-non-zts-20090626/ 为php扩展的动态库存放目录 5、编译安装 [root@localhost mysql]#make [root@localhost mysql]#make install 6、编译完成之后,将会自动把mysql.so放到了默认的php扩展目录下(phpinfo可查看,我的为 /usr/local/php/lib/php/extensions/no-debug-zts-20090626),再修改php.ini,去掉;extension=mysql.so前面的分号。如果没有这句,需要自行添加。 不过有一点需要注意的是,生成的模块名叫mysql.so,跟php.ini里面的php_mysql.so名字不一致,必须把mysql.so改名为php_mysql.so,也可修改php.ini中的文件名,总之文件名必须一致.'./configure' '--prefix=/usr/local/php' '--with-curl' '--with-freetype-dir' '--with-gd' '--with-gettext' '--with-iconv-dir' '--with-kerberos' '--with-libdir=lib64' '--with-libxml-dir' '--with-mysqli' '--with-openssl' '--with-pcre-regex' '--with-pdo-mysql' '--with-pdo-sqlite' '--with-pear' '--with-png-dir' '--with-jpeg-dir' '--with-xmlrpc' '--with-xsl' '--with-zlib' '--with-bz2' '--with-mhash' '--enable-fpm' '--enable-bcmath' '--enable-libxml' '--enable-inline-optimization' '--enable-gd-native-ttf' '--enable-mbregex' '--enable-mbstring' '--enable-opcache' '--enable-pcntl' '--enable-shmop' '--enable-soap' '--enable-sockets' '--enable-sysvsem' '--enable-sysvshm' '--enable-xml' '--enable-zip'

PHP的安装虽然有时候很简单,可是如果应用一多,我们安装起来就很头痛了!出错最多的就是安装PHP扩展的时候了。其实不管是你是Apache类的应用还是Nginx类的,PHP的安装都不是很简单,虽然网上有很多configure参数,但是那不一定是适合你的,因为很多都直接关系着你的系统版本和内核。因此要自己亲自不断的调试,才能完全安装成功。

本文总结了一些常见的configure错误信息和解决这些错误的经验。

1、configure: error: No curses/termcap library found

网上有的说法是:–with-named-curses-libs=/usr/lib/libncursesw.so.5其实是不对的,虽然能解决configure的错误,但是make的时候会提示错误,正确的做法应该是centos: yum -y install ncurses-develdebian: apt-get install libncurses5-dev
