mysql服务器不能正常启动

昨天晚上将服务器重启了，今天数据库连不上了，不知道错误在哪里，在mysql安装文件夹里乱撞。

终于在/usr/local/mysql/data文件夹中找打了liu.err，打开一看错误如下：

080506 11:43:50  mysqld started
080506 11:43:50  InnoDB: Started; log sequence number 0 759524575

080506 11:43:50 [ERROR] Failed to open log (file './mysql-bin.000002', errno 13)

对于这个问题，可以在/etc/my.cnf中配置log的具体存放位置，做了如下处理

$ mkdir /var/log/mysql/binary

cd /var/log
$ chown -R mysql:mysql ./mysql/binary
$ chmod =R 770 /var/log/mysql/binary
