    Dear   jack,

    Yes, we can install config server firewall (csf) which is the best firewall used now.

    1) Login into the server as a root user.

    2) change the Directory

    cd /usr/src

    3) remove your old files
    rm -fv csf.tgz

    4) Download the files

    5) Extract the files
    tar -xzf csf.tgz
    6) cd csf
    7) using the editor change the following

    vi /etc/csf/csf.conf

    make allow 1 to 0

    8) yes we whave completed installing the csf .

    Commands used for csf .

    csf -a IP [name]
    csf -a <IP> [] (Allow IP)
    csf -d <IP> [] (Deny IP)
    csf -r (to restart the service)
    csf -ar <IP> (for removing the IP)
    csf -g <IP> (IP searching)

    Hello All,

    The issue may be  permissions denied  in phpmyadmin configuration file .

    1)Login into the server as a root user.

    2)see phpmyadmin is installed or not

    3) If installed, then see the configuration file.

    4) vi /etc/httpd/conf.d/phpMyAdmin.conf

    If you want to allow from all then delete every thing and paste this.

    <Directory “/usr/share/phpMyAdmin”>
    Order Deny,Allow
    Deny from none
    Allow from all

    Alias /phpMyAdmin /usr/share/phpMyAdmin
    Alias /phpmyadmin /usr/share/phpMyAdmin

    5) save and exit.

    6) Restart the Apache.

    Yes we can list all the files

    1)log into the  server
    2)  Generally we use this command for listing the files

    [root@localhost]# ls

    list of files will be displayed.

    3) A command  which is used  to display all the things .

    [root@localhost]#  ls -l

    For example :

    login into your server

    [root@localhost]# pwd

    it will result

    [root@localhost] ls -l
    -rw——-. 1 root root 1366 Mar 14 2016 anaconda-ks.cfg
    -rw-r–r– 1 root root 14540 Nov 5 2012 epel-release-latest-6.noarch.rpm
    -rw-r–r– 1 root root 14540 Nov 5 2012 epel-release-latest-6.noarch.rpm

    This will be the output.

    Hello James,

    As per my knowledge this issue may be due to mis- configuration in Apache configuration .

    so, see Apache is properly configured.

    restart the Apache series.

    [root@localhost]# service httpd restart

    see that iptables are off

    [root@localhost]#service iptables off

    Disable the selinux

    vi /etc/sysconfig/selinux
    # This file controls the state of SELinux on the system.
    # SELINUX= can take one of these three values:
    # enforcing – SELinux security policy is enforced.
    # permissive – SELinux prints warnings instead of enforcing.
    # disabled – SELinux is fully disabled.
    # SELINUXTYPE= type of policy in use. Possible values are:
    # targeted – Only targeted network daemons are protected.
    # strict – Full SELinux protection.
    # SETLOCALDEFS= Check local definition changes

    Change SELINUX=enforcing to SELINUX=disabled

    If you are still facing the error then see the space must be full.

    [root@localhost]# df -h

    if it is 100% used then this may be error.

    clear all the logs see that some space is left.

    This tutorial may help in getting your issue resolved .

    Login into your server as a root user.

    [root@localhost]# vncpassword

    password :

    set the password :

    re-enter the password:

    then exit.

    Install vnc viewer on your local where you want to monitor

    In place of ip replace with your server ip:5901

    5901 is the default port

    then connect.

    This issue may be resolved by upgrading your MySQL version.

    To see the present version which is installed in your system.

    see the version

    [root@localhost]# rpm -qa | grep mysql

    Install and activate the REMI and EPEL RPM Repositories

    [root@localhost]# wget && rpm -Uvh epel-release-latest-6.noarch.rpm

    [root@localhost]# wget && rpm -Uvh remi-release-6*.rpm

    To to enable the REMI repository globally:

    [root@localhost]# vi /etc/yum.repos.d/remi.repo

    under remi section change enables=0 to enabled 1

    save and exit.

    update and mysql 5.x to latest

    [root@localhost]# yum -y update mysql*

    [root@localhost]# rpm -qa | grep mysql
