linux上php连接mysql错误
我的php版本是5.2.13,ysql版本是5.0，在执行下面的语句时
$con = mysql_connect($host_port,$user,$passwd);
报了错误：
PHP Fatal error: Call to undefined function mysql_connect()

我查看了下phpinfo(）里的信息，有如下两个选项：'--with-mysql=shared,/usr' '--with-mysqli=shared,/usr/bin/mysql_config'
另外，在我的/etc/php.ini中查看extension_dir = "/usr/lib64/php/modules"，在/usr/lib64/php/modules 这个目录下，却发现没有mysql.so文件。
我尝试了下：
把
/usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi/auto/DBD/mysql/mysql.so
下的mysql.so拷贝到 /usr/lib64/php/modules下，再执行一次
$con = mysql_connect($host_port,$user,$passwd);
仍然报： Call to undefined function mysql_connect()

请问我是不是还要装某些包啊？比如php-mysql和papache2-mod_php这两个包
------解决方案--------------------
mysql启动了吗？service mysql start 或者 service mysqld start
或者查看一下而 error log

------解决方案--------------------
你看一下你执行php的用户对于mysql.so的权限
