整理了一些FreeBSD 环境下Mysql问题的解决方法,供大家参考!

1 修改root用户的密码时出现错误:

# mysqladmin -uroot -p password 'newpassword'

Enter password:

mysqladmin: connect to server at 'localhost' failed

error: 'Access denied for user 'root'@'localhost' (using password: YES)'

解决方案

# /etc/init.d/mysql stop

# mysqld_safe --user=mysql --skip-grant-tables --skip-networking &

# mysql -u root mysql

mysql> UPDATE user SET Password=PASSWORD('newpassword') where USER='root';

mysql> FLUSH PRIVILEGES;

mysql> quit

# /etc/init.d/mysql restart

# mysql -uroot -p

Enter password:

mysql>

问题解决哈!

2 启动Mysql时失败

提示Can’t connect to local MySQL server through socket

转载:

没有进行test。

启动mysql 报错:

ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’ (2)

1、先查看 /etc/rc.d/init.d/mysqld status 看看m y s q l 是否已经启动.

另外看看是不是权限问题.

2、确定你的mysql.sock是不是在那个位置,

mysql -u 你的mysql用户名 -p -S /var/lib/mysql/mysql.sock

3、试试:service mysqld start

4、如果是权限问题,则先改变权限 #chown -R mysql:mysql /var/lib/mysql

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

启动 MySQL: [ 确定 ]

[root@localhost ~]# mysql -uroot -p

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

原因是,/var/lib/mysql 的访问权限问题。

shell> chown -R mysql:mysql /var/lib/mysql

接着启动服务器

shell> /etc/init.d/mysql start

服务器正常启动后察看 /var/lib/mysql 自动生成mysql.sock文件。

但是我的问题仍然没有得到解决。

问题终于解决:

方法: 修改/etc/my.conf:

[mysqld]

datadir=/usr/local/mysql/data

socket=/var/lib/mysql/mysql.sock

[mysql.server]

user=mysql

basedir=/usr/local/mysql

If there is not currently a section called [client], add one at the bottom of the file and copy the socket= line under the [mysqld] section such as:

[client]

socket=/var/lib/mysql/mysql.sock

发现依旧如此,,运行/etc/init.d/mysql start报错: Starting MySQLCouldn't find MySQL manager or server

是mysqld服务没启,运行/usr/local/mysql/bin/mysqld_safe &

问题解决。
