PHP安装及与apache整合

软件版本

• apache 2.4.29
• php 5.4.45

php安装

# tar -zxvf php-5.4.45.tar.gz
# cd php-5.4.45
# ./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2/bin/apxs --with-libxml2=/usr/include/libxml2    
# make 
# make install

安装中的错误及解决

如下步骤出现错误

/configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2/bin/apxs --with-libxml2=/usr/include/libxml2

错误log：

Sorry, I cannot run apxs.  Possible reasons follow:

1. Perl is not installed
2. apxs was not found. Try to pass the path using --with-apxs2=/path/to/apxs
3. Apache was not built using --enable-so (the apxs usage page is displayed)

The output of /usr/local/apache2/bin/apxs follows:
./configure: /usr/local/apache2/bin/apxs: /replace/with/path/to/perl/interpreter: bad interpreter: No such file or directory
configure: error: Aborting

按照提示安装perl

# perl -v  //先查看果然没安装
# yum install -y perl
# perl -v  //安装成功
This is perl, v5.10.1 (*) built for x86_64-linux-thread-multi

再次./configure仍然提示这个错误。于是百度。。。。
才知道需要先按照perl再按照apache才行，不安装perl的情况下安装apache，apxs就无法运行。
补救办法：
查看文件

# cat /usr/local/apache2/bin/apxs

第一行是 #!/replace/with/path/to/perl/interpreter -w
改为：#!/usr/bin/perl -w
再次：

./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2/bin/apxs --with-libxml2=/usr/include/libxml2

成功！

与apache整合

1.httpd.conf修改

如果php安装正确，apache的配置文件会自动被备份(httpd.conf.bak)和修改，修改如下
打开如下注释,加载php模块。
LoadModule php5_module modules/libphp5.so

如果想让apache解析php文件，还需要在httpd.conf中加入（#AddOutputFilter INCLUDES .shtml下面）：

AddType application/x-httpd-php .html
AddHandler php5-script .php

1. 让apache解析PHP代码
   AddHandler php5-script .php
2. 让apache解析html里的PHP代码
   AddType application/x-httpd-php .html

2.apache/htdos/中加入php文件如：info.php

<?php
phpinfo();
?>

3.重启apache

4.访问 http:ip/info.php 看是否被解析
