php代码很简单: $server="127.0.0.1"; println("Begin"); $link = mysql_connect($server,"mysql","mysql"); if (!$link) { die('Could not connect: ' . mysql_error().mysql_errno()); } linux本机下使用php mysql.php 可以查看运行结果,但是 在我的wind

php代码很简单:


$server="127.0.0.1";
println("Begin");
$link = mysql_connect($server,"mysql","mysql");
if (!$link) {
    die('Could not connect: ' . mysql_error().mysql_errno());
}

linux本机下使用php mysql.php 可以查看运行结果,但是 在我的windows浏览器下报错:


Could not connect: Can't connect to MySQL server on '127.0.0.1' (13) 2003

原因:


#getsebool -a | grep httpd
[neo@neo phpMyTest]$ getsebool -a | grep httpd


发现 httpd_can_network_connect --> off
解决方案:


#setsebool httpd_can_network_connect 1

原来是 SELINUX,所以我一般直接关闭SELINUX和 iptables ip6tables


# 关闭SELINUX
chkconfig --level 12345 iptables off

chkconfig --level 12345 ip6tables off

service iptables stop

service ip6tables stop


查看SELinux状态:

1、/usr/sbin/sestatus -v      ##如果SELinux status参数为enabled即为开启状态

SELinux status:                 enabled

2、getenforce                 ##也可以用这个命令检查

关闭SELinux:

1、临时关闭(不用重启机器):

setenforce 0                  ##设置SELinux 成为permissive模式

                              ##setenforce 1 设置SELinux 成为enforcing模式

2、修改配置文件需要重启机器:

修改/etc/selinux/config 文件

将SELINUX=enforcing改为SELINUX=disabled
