由于mysql-bin.0000X日志文件的存在，经常导致数据库文件不大的情况下却能产生几个G以上的日志文件，下面就教您删除mysql-bin.0000X日志文件的方法。
[chinastor.com-root@jiucool var]#/usr/local/mysql/bin/mysql -u root -p
Enter password: (输入密码)
Welcome to the MySQL monitor. Commands end with ; or g.
Your MySQL connection id is 264001
Server version: 5.1.35-log Source distribution
Type ‘help;’ or ‘h’ for help. Type ‘c’ to clear the current input statement.
mysql>reset master; (清除日志文件)
Query OK, 0 rows affected (8.51 sec)
mysql>
好了,我们再来查看下mysql文件夹占用多少空间
[chinastor.com-root@jiucool var]#du -h –max-depth=1 /usr/local/mysql/
37M /usr/local/mysql/var
70M /usr/local/mysql/mysql-test
15M /usr/local/mysql/lib
448K /usr/local/mysql/include
2.9M /usr/local/mysql/share
7.6M /usr/local/mysql/libexec
17M /usr/local/mysql/bin
11M /usr/local/mysql/docs
2.9M /usr/local/mysql/sql-bench
163M /usr/local/mysql/
好了,看一下,整个mysql 目录才占用163M大小!OK,没问题,既然mysql-bin.0000X日志文件占用这么大空间,存在的意义又不是特别大,那么我们就不让它生成吧.
[chinastor.com-root@jiucool var]#find / -name my.cnf
找到了my.cnf 即mysql配置文件,我们将log-bin=mysql-bin 这条注释掉即可.
# Replication Master Server (default)
# binary logging is required for replication
#log-bin=mysql-bin
重启下mysql吧.
OK,至此,删除mysql-bin.0000X日志文件操作完成. 以后再不会因为就几十M的数据库大小生成N个G的日志文件啦。
