I am having problems launching MySQL on my local machine. Every time I try to launch the instance I get an:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2 "No such file or directory")
For creating the required file I followed this solution changing the directory /var/lib/... to /var/run/... since it is how my configuration is set. The weird thing is that when I follow the steps described the process is launched and I can access to my database, but after a while it suddenly stops and the files (mysqld.sock and mysqld.pid) dissappear. How can this be possible? How can avoid it from happening?
The settings on my 50-server.cnf of my mariadb are:
#
# * Basic Settings
#
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
lc-messages-dir = /usr/share/mysql
skip-external-locking
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
bind-address = localhost

I have installed and setup phpMyAdmin in app engine, with MySQL installed in compute engine. I am receiving this error mysqli_real_connect(): (HY000/2002): No such file or directory when logging into phpMyAdmin. I have set up vpc access connector in app.yaml, and opened port 3306 in the compute engine.
config.inc.php in phpMyAdmin:
$cfg['Servers'][$i]['host'] = '10.126.0.9:3306';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
in compute engine with MySQL installed
with config /etc/mysql/mysql.conf.d/mysqld.conf
[mysqld]
#

#
user = mysql
# pid-file = /var/run/mysqld/mysqld.pid
# socket = /var/run/mysqld/mysqld.sock
# port = 3306
# datadir = /var/lib/mysql
# If MySQL is running as a replication slave, this should be
# changed. Ref https://dev.mysql.com/doc/refman/8.0/en/server-system-variables.html#sysvar_tmpdir

bind-address = 10.126.0.9
#mysqlx-bind-address = 0.0.0.0
On top of that, I have created user to login from phpMyAdmin
CREATE USER 'myadminLogin'#'*' IDENTIFIED BY 'password';
MySQL and OS variant
mysql -V

Update
After the above changes, I no longer see the login panel but currently being directed straight to the page below. What is the issue?
The first thing that stands out is that there's a slight mistake in your config.inc.php; the line $cfg['Servers'][$i]['host'] = '10.126.0.9:3306'; should not include the port. There's a separate directive $cfg['Servers'][$i]['port'] if you need to override the default, which is 3306 so you won't even need that. Change your host line to $cfg['Servers'][$i]['host'] = '10.126.0.9'; and see if that changes anything.
after resolving the issue of Apache and Mysql, suddenly I am facing the issue as Localhost not found.
No webpage was found for the web address: http://localhost/phpmyadmin
Issue I have resolved for MYSQL is :
# The following options will be passed to all MySQL clients
[client]
# password = your_password
#port = 3306
port =8111
socket = "C:/xampp/mysql/mysql.sock"
Here follows entries for some specific programs
# The MySQL server
[mysqld]
#port= 3306
port = 8111
socket = "C:/xampp/mysql/mysql.sock"
basedir = "C:/xampp/mysql"
tmpdir = "C:/xampp/tmp"
datadir = "C:/xampp/mysql/data"
I have port to 8111 in both the cases as this was the only option which helped me out while running MYSQL.
Any help?
The problem may be related with Your Localhost Port. rather than typing http://localhost/phpmyadmin type like 'http://localhost:PortNumber/phpmyadmin'.
check Your port Number at 'httpd.conf' file. these are the basic
Listen 'Your Port number like 80 or else
ServerName localhost:'Your Port number like 80 or else
I'm trying to allow external access to MySQL server. First I changed my.cnf to this (part of my.cnf):
[mysqld_safe]
socket = /var/run/mysqld/mysqld.sock
nice = 0
[mysqld]
#
# * Basic Settings
#
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
lc-messages-dir = /usr/share/mysql
skip-external-locking
#
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
bind-address = 0.0.0.0
In /etc/hosts.allow I added:
mysqld: all
Also I added user 'root'#'%', but what I have is that:
I'm trying to connect from server to server using external host name:
root#******:~# mysql -h******.com -u root -p
ERROR 2013 (HY000): Lost connection to MySQL server at 'reading initial communication packet', system error: 0
But using 'localhost' all is fine:
root#******:~# mysql -hlocalhost -u root -p
MySQL Server version: 5.5.43
Ubuntu 14.10 (GNU/Linux 3.16.0-23-generic x86_64)
You should run the commands after creating user-
GRANT ALL ON dbname.* TO 'root'#'%' IDENTIFIED BY 'root';
FLUSH HOSTS;
FLUSH PRIVILEGES;
if you have already run this code then there could be fire wall problem-
I am using Amazon Cloud to deploy my web services. However, this requires a MySQL instance and I already installed it. In order to allow remote connectivity to MySQL database, I followed the below sequence as elaborated in MySQL documentation and even in the below thread.
Edit my.cnf file to change the following.
[mysqld]
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
language = /usr/share/mysql/English
bind-address = <server ip OR 0.0.0.0>
The same solutions discussed in detail, following posts.
Remote Connections Mysql Ubuntu
http://www.cyberciti.biz/tips/how-do-i-enable-remote-access-to-mysql-database-server.html
However, as soon as I edited the my.cnf file as mentioned, the MySQL server failed to restart. I tried my best to recover this, it's failing instead.
Could anyone help me to identify and resolve the issue, would be a great help.
Verify that the MySQL server isn't running.
Try setting the bind-address to 0.0.0.0
bind-address = 0.0.0.0
Verify that the files are deleted
/var/run/mysqld/mysqld.sock
/var/run/mysqld/mysqld.pid
I can't figure out why i cant access a remote MySQL server in ubuntu inside a VMware. I already have the codes, and it's successfully connecting to my localhost as well as insert, delete and update of data's. But when I make a new connection string with specified IP server address it show an error:
I can only access the files in that server through SSH and browser (192.168.56.xxx/phpmyadmin).
Here's my code for connection string.
Dim conn As New MySqlConnection
conn.ConnectionString = "Server=192.168.56.xxx;port=3306;User=root;password=mypassword;Database=prodDB_vb"
conn.Open()
MessageBox.Show("Connection to Database has been opened.")
cmd.Connection = conn
I already read a lot of forums about this. But dont understand what they are pointing to.
Also i executed the code:
GRANT ALL PRIVILEGES ON prodDB_vb TO 'root#*' IDENTIFIED BY 'my_password';
FLUSH PRIVILEGE;
The only thing i know is that i cannot find the my.cnf in the server files, but already change my my.ini in my localhost's bind ip address.
#bind-address="127.0.0.1"
3306 is listening
And i have this in my my.cnf
Why having this error?
Anyone please help.
Did you check to make sure that MySQL is actually listening on 3306? Run a netstat -tlpn and provide the results. If you don't see 3306 then its probably not.
In my.cnf you should verify that --skip-networking is commented out
[mysqld]
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
language = /usr/share/mysql/English
bind-address = 65.55.55.2
# skip-networking
To locate your CNF file
Edited:
For example, if your MySQL server IP is 192.162.0.3 then entire block should be look like as follows:
[mysqld]
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
language = /usr/share/mysql/English
bind-address = 192.168.0.3
# skip-networking
....
..
....
bind-address : IP address to bind to.
skip-networking : Don’t listen for TCP/IP connections at all. All interaction with mysqld must be made via Unix sockets. This option is highly recommended for systems where only local requests are allowed. Since you need to allow remote connection this line should removed from file or put it in comment state.
Then we have to Restart mysql service to take change in effect:
/etc/init.d/mysql restart
