- Starting the Server Process Manually
The reason for MySQL server has gone away error, is often because MySQL’s waittimeout was exceeded. MySQL waittimeout is the number of seconds the server waits for activity on a non-interactive connection before closing it. You should make sure the waittimeout is not set too low. The default for MySQL waittimeout is 28800 seconds.
- Stop MySQL sudo service mysql stop. Make MySQL service directory. Sudo mkdir /var/run/mysqld. Give MySQL user permission to write to the service directory. Sudo chown mysql: /var/run/mysqld. Start MySQL manually, without permission checks or networking. Sudo mysqldsafe -skip-grant-tables -skip-networking & 5.Log in without a password.
- For installation on macOS, including using both the binary package and native PKG formats, see Section 2.4, “Installing MySQL on macOS”. For information on making use of an macOS Launch Daemon to automatically start and stop MySQL, see Section 2.4.3, “Installing a MySQL Launch Daemon”.

There are several different methods to start or stop the MariaDB Server process. There are two primary categories that most of these methods fall into: starting the process with the help of a service manager, and starting the process manually.
Service Managers
sysVinit and systemd are the most common Linux service managers. launchd is used in MacOS X. Upstart is a less common service manager.
Systemd
RHEL/CentOS 7 and above, Debian 8 Jessie and above, and Ubuntu 15.04 and above use systemd by default.
For information on how to start and stop MariaDB with this service manager, see systemd: Interacting with the MariaDB Server Process.
SysVinit
RHEL/CentOS 6 and below, and Debian 7 Wheezy and below use sysVinit by default.
For information on how to start and stop MariaDB with this service manager, see sysVinit: Interacting with the MariaDB Server Process.
launchd
launchd is used in MacOS X.
Upstart
Ubuntu 14.10 and below use Upstart by default.
Stop Mysqld Mac
Starting the Server Process Manually
mysqld
mysqld is the actual MariaDB Server binary. It can be started manually on its own.
Macos Stop Mysql
mysqld_safe
mysqld_safe is a wrapper that can be used to start the mysqld server process. The script has some built-in safeguards, such as automatically restarting the server process if it dies. See mysqld_safe for more information.
mysqld_multi
mysqld_multi is a wrapper that can be used to start the mysqld server process if you plan to run multiple server processes on the same host. See mysqld_multi for more information.
Stop Mysql Macos Command
mysql.server
Stop Mysql Mac
mysql.server is a wrapper that works as a standard sysVinit script. However, it can be used independently of sysVinit as a regular sh
script. The script starts the mysqld server process by first changing its current working directory to the MariaDB install directory and then starting mysqld_safe. The script requires the standard sysVinit arguments, such as start
, stop
, and status
. See mysql.server for more information.
