Linux下安装MySQL中一些错误的解决方法

1。在安装Mysql*.rpm 包时提试错误

error: Failed dependencies:
perl(CGI) is needed by MySQL-client-4.0.26-0
perl(DBI) is needed by MySQL-client-4.0.26-0
error: Failed dependencies:
perl(DBI) is needed by MySQL-server-4.0.26-0

perl DB_File-1.804-88
postgresql-libs-7.3.2-3
postgresql-7.3.2-3
postgresql-server-7.3.2-3
perl-CGI-2.81-88.i386.rpm
测试，解决
2。mysql之后出现的问题如下：启动
[root@localhost bin]# ./mysql
ERROR 2002 (HY000): Can’t connect to local MySQL server through socket

’/tmp/mysql.sock’ (2)
解决方法：
#chown -R mysql:mysql /var/lib/mysql
[root@localhost beinan]# /etc/init.d/mysqld start
启动 MySQL： [ 确定 ] 成功解决

3.解决mysql“Access denied for user ’root’@’localhost’”
错误1
Enter password:
ERROR 1045 (28000): Access denied for user ’root’@’localhost’ (using password:

YES)
错误2
# mysql -uroot -p
Enter password:
ERROR 1045 (28000): Access denied for user ’root’@’localhost’ (using password:

NO)
解决方法：
方法一：
# /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: <输入新设的密码newpassword> 测验成功

mysql>

解决方法二：
直接使用/etc/mysql/debian.cnf文件中[client]节提供的用户名和密码:
# mysql -udebian-sys-maint -p
Enter password: <输入[client]节的密码>
mysql> UPDATE user SET Password=PASSWORD(’newpassword’) where USER=’root’;
mysql> FLUSH PRIVILEGES;
mysql> quit

# mysql -uroot -p
Enter password: <输入新设的密码newpassword>

mysql>

解决方法三：(没有测试)
# mysql -uroot -p
Enter password: <输入/etc/mysql/debian.cnf文件中[client]节提供的密码>
