MYSQL无法启动 并出现了极其严重的错误

嘿呀

我装的是FedoraCore7在图形化界面安装的MySQL的全部11个包(yum install)
现在无论如何都无法启动

求助于各位大侠！是跪求！
[root@localhost ~]# mysql -u root -p
Enter password:

[root@localhost ~]# /etc/rc.d/init.d/mysqld start

启动 MySQL：                                               [失败]

于是查看日志：

是权限问题吗？ 我一切都是在root下操作的啊 数据库还没有别的用户
我也运行了 mysql_install_db --user=root 还是不能启动
find -name host.frm 也的确没找到
谢谢各位大侠！跪谢！

InnoDB: The error means mysqld does not have the access rights to
InnoDB: the directory.
应该是权限问题。
有没新建mysql用户和用户组？

rsmgnu

大概是你的配置文件里mysql.sock的路径不对

看看/etc下，my.cnf文件，里面是不是有
/var/lib/mysql/mysql.sock

改成/tmp/mysql.sock试试，

这个问题俺遇到过，google 下，不难解决

：）

Aeonspr

注意看 /var 下面 mysql 相关的权限，以前我也遇到过一次，把权限重新设了就好了

嘿呀

真是谢谢楼上几位，这个论坛算回复最有价值的！赞！

不过仍存在问题
设置了权限 也更改了my.cnf

[root@localhost mysql]# chown -R mysql:mysql /var/lib/mysql
[root@localhost mysql]# cd /
[root@localhost /]# mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
[root@localhost /]# vi /etc/my.cnf

[mysqld]
datadir=/var/lib/mysql
socket=/tmp/mysql.sock
# socket=/var/lib/mysql/mysql.sock
user=mysql
# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).
old_passwords=1

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

SElinux也关了，google的方法都试过了，都没有用，所以感到很奇怪
谢谢大家，求助中～～～

（安装是图形化的添加软件安装的，不是安装下载的rpm包更不是编译源码安装的，没想到却还是有问题，所以感觉太菜了，linux恶补中～）

你的mysqld已经启动了一个进程.所以你再启动就出现了Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock'

ps aux|grep  mysql
看一下

嘿呀

装好了有没有初始化库，看看有没有mysql那个库

chenyx

配置修改后重启mysql了吗？

发现没有？mysql.sock路径不一样，说明你系统里可能装了2个mysql，配置不一样，你把mysql的完整路径也给出，再登陆
