try to change bin log directory: mysql-bin.index not found (Errcode: 13)

MySQL 5.1.54 Ubuntu 11.04

I'am try to change bin log directory in my.conf as:

[mysqld]
log_bin=/home/developer/logs/mysql/mysql-bin.log

After this changes MySQL server can't start with error:

/usr/sbin/mysqld: File '/home/developer/logs/mysql/mysql-bin.index' 
not found (Errcode: 13)
111005 12:47:58 [ERROR] Aborting

Permission for directory /home/developer/logs/mysql/ is 0777

What's going on?

As usual, the solution was simple but not obvious: it needed to edit apparmor settings I just added to /etc/apparmor.d/usr.sbin.mysqld a new string with path to target directory: /home/developer/logs/* rw

It works!

/usr/sbin/mysqld: File '/usr/binlogs/mysql-bin.index' not found (Errcode: 13)

It worked for me with:

chown -R mysql:mysql /usr/binlogs/

Just as an FYI for anyone who runs into a similar problem, the solution is basically the same, but the cause of the problem isn't obvious.

After upgrading Debian wheezy, mysql failed to start.

Somehow, I have no idea how, permissions on some of the files in /var/lib/mysql were not owned by the mysql user, thus preventing the server from firing up.

A chown -R mysql.mysql /var/lib/mysql fixed it.

I didn't do anything to mess up mysql, it was a standard:

apt-get update

apt-get upgrade

Something got hinky during the Debian upgrade and manual intervention was needed.

Option 1:

service mysqld stop

Copy the log files including the .index file to new location.

 cp mysql-bin.log* /path/to/binlogs
 cp mysql-bin.index /path/to/binlogs

Do Changes in the /etc/my.cnf file.

[mysqld]
log-bin=/path/to/newdirecory/mysql-bin

log-bin-index=/path/to/newdirectory/mysql-bin.index

service mysqld start

Option 2:

Use this utiltiy to relocate binary logs:

mysqlbinlogmove --binlog-dir=/server/data /new/binlog_dir

Selinux might enforce the rule that MySQL database files have to live in /var/lib/mysql and not anywhere else. Try turning off selinux (selinux=0 on kernel boot command line) if you moved mysql to another directory.

You need to give user permissions to the directory as follows:

chown -R mysql:mysql /home/developer/logs/mysql/

mysqld: File '/data/log/mysql/mysql-bin.index' not found (Errcode: 2 - No such file or directory)

I was really stuck in the middle of my MySQL Master - Slave setup. Finally the above was a permission issue, adding the below command solved my issue.

chown -R mysql:mysql /data/log/mysql/

Does your user have access to all upper directories? In special, the /home/developer/ directory? Try to log in with the mysql server account and touch the log file.

I had a similar problem when I was trying to change the datadir variable during a fresh install. The solution in my case was to run the first time start up with log-bin disabled. After that I was able to enable it again using the new path ...

Your config is wrong:

log_bin=/home/developer/logs/mysql/mysql-bin.log

You would use instead

log-bin=/home/developer/logs/mysql/mysql-bin.log

During replication configuration in "my.cnf" file needs to mention

server-id=1 log_bin=/var/log/mysql/mysql-bin.log

you can make your own directory and give permission. create directory "mysql" in /var/log/

chmod 777 mysql

this is applicable with MySQL version 5.7

You can also comment the line in my.cnf file which is defining the log location, so mysql will consider its default path and will start properly.

log-bin = /var/log/mysql/mysql-bin.log -> #log-bin = /var/log/mysql/mysql-bin.log.

This will be helpful if you are not concerned much about logs.

As documentation in mysql say https://dev.mysql.com/doc/refman/5.7/en/replication-options-binary-log.html#sysvar_log_bin

The variable is log_bin and not log-bin at least in version 5.7
