红色表示输入的命令.

[root@jiucool var]# /usr/local/mysql/bin/mysql -u root -p
Enter password:  (输入密码)

好了,我们再来查看下mysql文件夹占用多少空间?

[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.

[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,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.
