本人新安装solaris 9 +mysql 5，可是安完后，无法正常启动，log文件中报以下错误，请各位帮忙分析，可能的问题出在哪里，谢谢！给个提示也成啊。。，

开了日志么，先关了日志启动看看。
vi /etc/my.cnf
注释掉：log-bin=mysql-bin

上面的报错，是因为权限的问题
将mysql安装目录中var目录下的mysql-bin.000003，mysql-bin.000002，mysql-bin.000001三个文件的权限均设为mysq属主及组，问题就解决了，不过在解决之后，又发现了新的问题，同样贴出来
071219 17:14:00  mysqld started
071219 17:14:00  InnoDB: Started; log sequence number 0 43655
071219 17:14:00 [ERROR] /data2/bin/mysql/libexec/mysqld: Can't find file: './mysql/host.frm' (errno: 13)
071219 17:14:00 [ERROR] /data2/bin/mysql/libexec/mysqld: Can't find file: './mysql/host.frm' (errno: 13)
071219 17:14:00 [ERROR] Fatal error: Can't open and lock privilege tables: Can't find file: './mysql/host.frm' (errno: 13)
071219 17:14:00  mysqld ended

看上去又像是权限的问题，因为在网上查了些资料，说是error number=13就是permisstion deny，具体原因正在查，有结果我也会贴出来，请各位也帮忙分析一下是什么原因，谢谢！

果然是权限问题，将“安装目录/var/mysql下的host.frm属主和组也设成mysql即可，之后又报如下错，目前无解中。。。
