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?
回答1:
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!
回答2:
/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 stopCopy the log files including the .index file to new location.
cp mysql-bin.log* /path/to/binlogs cp mysql-bin.index /path/to/binlogsDo Changes in the
/etc/my.cnffile.[mysqld] log-bin=/path/to/newdirecory/mysql-bin log-bin-index=/path/to/newdirectory/mysql-bin.indexservice mysqld start
Option 2:
Use this utiltiy to relocate binary logs:
mysqlbinlogmove --binlog-dir=/server/data /new/binlog_dir
回答5:
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.
回答6:
You need to give user permissions to the directory as follows:
chown -R mysql:mysql /home/developer/logs/mysql/
回答7:
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/
回答8:
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.
回答9:
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 ...
回答10:
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
回答11:
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
回答12:
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.
回答13:
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
