PHP access Network exception after SELinux is enabled

APACHE03 Access Test Connection Http://admin.lt.mopgaming.com/auth/admin/login

Ping and Telnet specify that the appropriate port test will succeed,

However, when the firewall is enabled, the memcached and Redis ports are already in place, testing the connection is still unsuccessful.

Error:{"message": "Permission denied [tcp:\/\/198.44.240.242:6379]", "Code": "Data": null}{"message": " Undefined index: _sf2_meta "," code ": +," data ": null}

Problem reason to open selinux

Getsebool-a |grep httpd

[Email protected] ~]$ getsebool-a |grep-i httpd

Httpd_anon_write--off

HTTPD_DBUS_SSSD--off

。。。

You can see that selinux restricts access to external access to httpd

Setsebool-p httpd_can_network_connect=1

Immediate effect, you can access

Or, if you are unfamiliar with SELinux, turn off SELinux directly

Setenforce 0 Immediate effect

Getenforce

Or

/etc/sysconfig/selinux

Selinux=disabled Direct shutdown, restart effective
