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

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。

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.

The best tools and technologies for automating the creation of users in MySQL include: 1. MySQLWorkbench, suitable for small to medium-sized environments, easy to use but high resource consumption; 2. Ansible, suitable for multi-server environments, simple but steep learning curve; 3. Custom Python scripts, flexible but need to ensure script security; 4. Puppet and Chef, suitable for large-scale environments, complex but scalable. Scale, learning curve and integration needs should be considered when choosing.
