我们如何在Linux下安装PHP5呢?我们这里就详细的介绍一下Linux PHP5安装。服务器运行一段时间后,可能突然会需求添加某个扩展,如curl、pdo、xmlrpc等,这就需要在不重新编译PHP的情况下独立添加扩展。
下面以安装curl为例,介绍具体Linux PHP5安装步骤。
1.安装crul wget http://curl.haxx.se/download/curl-7.19.6.tar.gz tar -zxvf curl-7.19.6.tar.gz cd curl-7.19.6 ./configure --prefix=/usr/local/curl
<ol class="dp-xml"> <li class="alt"><span><span>make </span></span></li> <li class=""><span>make install </span></li> </ol>
2.编译生成扩展进入php源程序目录中的ext目录中,这里存放着各个扩展模块的源代码,选择你需要的模块,比如curl模块:
<ol class="dp-xml"><li class="alt"><span><span>cd curl </span></span></li></ol>
<ol class="dp-xml"> <li class="alt"><span><span>/usr/local/php5/bin/phpize </span></span></li> <li class=""> <span>./configure </span><span class="attribute"><font color="#ff0000">--with-curl</font></span><span>=/usr/local/curl </span><span class="attribute"><font color="#ff0000">--with-php-config</font></span><span>=/usr/local/php5/bin/php-config </span> </li> <li class="alt"><span> </span></li> <li class=""><span>make </span></li> <li class="alt"><span> </span></li> <li class=""><span>make install </span></li> </ol>
这样,curl.so就被复制到PHP对应目录(如:/usr/local/php5/lib/php/extensions/no-debug-non-zts-20090626/)
3.修改配置在php.ini里,设置扩展目录:
<ol class="dp-xml"><li class="alt"><span><span class="attribute"><font color="#ff0000">extension_dir</font></span><span> = </span><span class="attribute-value"><font color="#0000ff">"/usr/local/php5/lib/php/extensions/no-debug-non-zts-20090626/"</font></span><span> </span></span></li></ol>
并添加扩展模块引用:
<ol class="dp-xml"><li class="alt"><span><span class="attribute"><font color="#ff0000">extension</font></span><span> = </span><span class="attribute-value"><font color="#0000ff">curl</font></span><span>.so </span></span></li></ol>
4.检查并重启Apache
<ol class="dp-xml"><li class="alt"><span><span>/usr/local/php/bin/php -v </span></span></li></ol>
执行这个命令时,php会去检查配置文件是否正确,如果有配置错误,这里会报错,可以根据错误信息去排查。以上就是Linux PHP5安装的步骤,希望对大家有帮助。
