PHP 备忘录
1. 配置PHP过程出现这错误信息:
原因正如上面信息所说,要装libxml2,注意的是要装libxml2常规包和libxml2-devel开发包。一般前者是已经装了的,后者要另外下载
在CentOS中使用yum就可以下载安装:
yum install libxml2
yum install libxml2-devel
注意两者是不一样的,第一指令是搜索不出libxml2-devel软件的。
如果要到网站下载,可以到http://rpm.pbone.net下载,该网站很多RPM
2. 配置PHP过程出现这错误信息:Cannot find MySQL header in files ....
错误原因是PHP配置程序没有根据配置参数中提供的MySQL目录找到mysql.h这个头文件。如果有装MySQL的话,只要添加参数--with-mysql=[MySQL安装目录]就好。不过这里要注意,该头文件是在 ..../mysql/includes/mysql.h 这个位置,但参数中指定的应该是 --with-mysql=..../mysql,而不是includes,这类的mysql是假设的安装根目录名。
3. 安装PHP过后不能遗忘两个操作:1)从安装文件下复制php.init-development到安装目录的lib下(默认是/usr/local/lib),并命名为php.ini ; 2)在httpd.conf下配置解释php脚本。
