PHP Connection failed SQLSTATE HY000 2002 Connection refused

Question

I am trying to use a PHP connection to connect MySQL Database which is on phpmyadmin  Nothing fancy about the connection just trying to see whether the connection is successful or not  I am using MAMP to host the database  the connection I am trying to use is this     lt  php  servername    127 0 0 1    username    root    password    root    try        conn   new PDO  mysql host  servername dbname AppDatabase    username   password          set the PDO error mode to exception      conn- gt setAttribute PDO  ATTR ERRMODE  PDO  ERRMODE EXCEPTION       echo  Connected successfully      catch PDOException  e        echo  Connection failed       e- gt getMessage        gt    I have been using postman to test to see if the connection is working  but I keep receiving this error message          Connection failed  SQLSTATE HY000   2002  Connection refused   Before I was receiving an error message of      Connection failed  SQLSTATE HY000   2002  No such file or directory   This was because I had set the servername to localhost  through changing this to the IP address it has given me connection refused and I have no idea what is wrong   Any help regarding this would be appreciated

I found the reason why the connection was not working  it was because the connection was trying to connect to port 8888  when it needed to connect to port 8889    conn   new PDO  mysql host  servername port 8889 dbname AppDatabase    username   password      This fixed the problem  although changing the server name to localhost still gives the error   Connection failed  SQLSTATE HY000   2002  No such file or directory  But it connects successfully when the IP address is entered for the server name

In my case MySQL sever was not running  I restarted the MySQL server and issue was resolved    on ubuntu server sudo  etc init d mysql start  To avoid MySQL stop problem  you can use the  quot initctl quot  utility in Ubuntu 14 04 LTS Linux to make sure the service restarts in case of a failure or reboot  Please consider talking a snapshot of root volume  with mysql stopped  before performing this operations for data retention purpose 8   You can use the following commands to manage the mysql service with  quot initctl quot  utility with stop and start operations    sudo initctl stop mysql   sudo initctl start mysql  To verify the working  you can check the status of the service and get the process id  pid   simulate a failure by killing the  quot mysql quot  process and verify its status as running with new process id after sometime  typically within 1 minute  using the following commands    sudo initctl status mysql           get pid   sudo kill -9  lt pid gt                   kill mysql process   sudo initctl status mysql           verify status as running after sometime   Note   In latest Ubuntu version now initctl is replaced by systemctl
