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>
Copy after login

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>
Copy after login

执行phpize生成编译文件,phpize在PHP安装目录的bin目录下/usr/local/php5/bin/phpize运行时,可能会报错:Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONF environment variable is set correctly and then rerun this script.“,需要安装autoconf:yum install autoconf(RedHat或者CentOS)、apt-get install autoconf(Ubuntu Linux)生成配置文件,并编译生成模块:
<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>
Copy after login

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>
Copy after login

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>
Copy after login

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>
Copy after login

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。

Four ways to implement multithreading in C language Four ways to implement multithreading in C language Apr 03, 2025 pm 03:00 PM

Multithreading in the language can greatly improve program efficiency. There are four main ways to implement multithreading in C language: Create independent processes: Create multiple independently running processes, each process has its own memory space. Pseudo-multithreading: Create multiple execution streams in a process that share the same memory space and execute alternately. Multi-threaded library: Use multi-threaded libraries such as pthreads to create and manage threads, providing rich thread operation functions. Coroutine: A lightweight multi-threaded implementation that divides tasks into small subtasks and executes them in turn.
