CentOS PHP using 127.0.0.1 can not connect to Mysql solution _mysql

Source: Internet
Author: User

The PHP code is simple:

Copy Code code as follows:

$server = "127.0.0.1";
println ("Begin");
$link = mysql_connect ($server, "MySQL", "MySQL");
if (! $link) {
Die (' Could not connect: '. Mysql_error (). Mysql_errno ());
}

Linux native use of PHP mysql.php can view the results of the run, but in my Windows browser error:

Copy Code code as follows:

Could not Connect:can ' t connect to MySQL server on ' 127.0.0.1 ' (13) # 2003

Reason:

Copy Code code as follows:

#getsebool-A | grep httpd
[Neo@neo phpmytest]$ getsebool-a | grep httpd

Found Httpd_can_network_connect--> off
Solution:
Copy Code code as follows:

#setsebool Httpd_can_network_connect 1

It turned out to be SELINUX, so I generally shut down SELINUX and iptables ip6tables directly.

Copy Code code as follows:

# Close SELinux
Chkconfig--level 12345 iptables off

Chkconfig--level 12345 ip6tables off

Service Iptables Stop

Service Ip6tables Stop


To view the SELinux status:

1,/usr/sbin/sestatus-v # #如果SELinux Status parameter is enabled that is open

SELinux status:enabled

2, Getenforce # #也可以用这个命令检查

Close SELinux:

1, temporarily shut down (do not restart the machine):

Setenforce 0 # #设置SELinux become permissive mode

# #setenforce 1 set SELinux become enforcing mode

2, modify the configuration file needs to reboot the machine:

modifying/etc/selinux/config files

Change Selinux=enforcing to Selinux=disabled
