mysql5.5 启动报错:File './mysql-bin.index' not found (Errcode: 13)

初始化玩数据库之后，使用mysqld_safe启动mysql数据库，如下发现，启动失败

[root@SVNServer bin]# ./mysqld_safe --user=mysql&
[1] 20539
[root@SVNServer bin]# 110806 00:32:19 mysqld_safe Logging to '/usr/local/mysql5.5/data/SVNServer.err'.
110806 00:32:20 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql5.5/data
110806 00:32:20 mysqld_safe mysqld from pid file /usr/local/mysql5.5/data/SVNServer.pid ended

上面只能看到mysql启动失败，具体的原因，需要查看数据库目录下的.err文件，查看.err文件，内容如下：

110806 00:32:20 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql5.5/data
^G/usr/local/mysql5.5/bin/mysqld: File './mysql-bin.index' not found (Errcode: 13)
110806  0:32:20 [ERROR] Aborting

110806  0:32:20 [Note] /usr/local/mysql5.5/bin/mysqld: Shutdown complete

110806 00:32:20 mysqld_safe mysqld from pid file /usr/local/mysql5.5/data/SVNServer.pid ended

红色字标出来的就是这次错误报告，errcode13，一般就是权限问题，mysql用户是否对数据库目录内的所有文件具有写的权限，查看一下权限，将data目录的有所者赋给mysql用户，

redhat系统中可以使用，chown mysql.mysql -R data

好了，现在再启动一下mysql
