I cannot start MySQL on Linux - mysqld_safe error

Question

I found in many forums on the Internet, but I did not find my solution. When I start the mysql service on linux ubuntu server 12.04, I get this error:

root@stroke :/# mysqld_safe & [1] 5789 root@stroke :/# 131001 10:12:29 mysqld_safe Logging to syslog. 131001 10:12:29 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql 131001 10:12:29 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended 

I already got permission to mysql folder, I also tried to create a new password for mysql root. But so far nothing has happened.

Thanks for the help.

Some information:

 root@stroke :/# /etc/init.d/mysql start Rather than invoking init scripts through /etc/init.d, use the service(8) utility, eg service mysql start Since the script you are attempting to invoke has been converted to an Upstart job, you may also use the start(8) utility, eg start mysql start: Job failed to start

Answer 1

MySQL runs under its own user, so running it as root is not a smart solution. And now, when you have already tried that some of your files may be root, so that the service does not start.

• Make sure that the entire directory with the MySQL database belongs to the mysql user.
• Try to start the service using the upstart: start mysql
• In the MySQL database directory, check the log file.

Is port 3306 being used? Try:

 netstat -an | grep 3306 

Edit: how do you start mysql? Try:

 /etc/init.d/mysql start
