See the manual for the semantics of the 'password expired' flag. Also, the account for the anonymous user has been removed. In addition, you can run: /usr/bin/mysql_secure_installation which will also give you the option of removing the test database. This is strongly recommended for production servers. See the manual for more instructions. Please report any problems at http://bugs.mysql.com/ The latest information about MySQL is available on the web at http://www.mysql.com Support MySQL by buying support/licenses at http://shop.mysql.com New default config file was created as /usr/my.cnf and will be used by default by the server when you start it. You may edit this file to change server settings
注意:若是安装 MySQL-server-5.5.37-1.el6.i686.rpm ,该版本较低,可能会报错如下:
[root@localhost mysql]# rpm -ivh MySQL-server-5.5.37-1.el6.i686.rpm error: Failed dependencies: libc.so.6(GLIBC_2.12) is needed by MySQL-server-5.5.37-1.el6.i686 libc.so.6(GLIBC_2.7) is needed by MySQL-server-5.5.37-1.el6.i686 rpmlib(FileDigests) <= 4.6.0-1 is needed by MySQL-server-5.5.37-1.el6.i686 rpmlib(PayloadIsXz) <= 5.2-1 is needed by MySQL-server-5.5.37-1.el6.i686 [root@localhost mysql]#
1.2、安装MySQL-client-5.6.17-1.linux_glibc2.5.i386.rpm
[root@localhost mysql]# rpm -ivh MySQL-client-5.6.17-1.linux_glibc2.5.i386.rpm Preparing... ########################################### [100%] 1:MySQL-client ########################################### [100%] [root@localhost mysql]#
1.3、安装MySQL-devel-5.6.17-1.linux_glibc2.5.i386.rpm
[root@localhost mysql]# rpm -ivh MySQL-devel-5.6.17-1.linux_glibc2.5.i386.rpm Preparing... ########################################### [100%] 1:MySQL-devel ########################################### [100%] [root@localhost mysql]#
通过命令行连接mysql数据库,测试是否安装成功:
输入测试命令如下:
mysql -uroot -p
上述命令可能导致登陆失败如下:
Warning: Using a password on the command line interface can be insecure. ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
此时,可尝试如下操作:
先关闭mysql:
service mysql stop
[root@localhost home]# mysqld_safe --skip-grant-tables &mysql -u root [1] 5257 ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) [root@localhost home]# 140910 13:13:08 mysqld_safe Logging to '/var/lib/mysql/localhost.localdomain.err'. 140910 13:13:08 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
再接着重新打开个终端,登陆mysql,修改相应用户的密码:
root@localhost home]# mysql -uroot -p mysql> use mysql;mysql> update user set password=PASSWORD('root') where User='root'; ----修改用户访问权限: mysql> grant all privileges on *.* to 'root'@'192.168.1.%' identified by 'mysql' with grant option; mysql> flush privileges; mysql> quit;
mysql -uroot -proot 登陆:
--这句话重新设置一次密码! mysql> SELECT 1;ERROR 1820 (HY000): You must SET PASSWORD before executing this statement mysql> SET PASSWORD = PASSWORD('root'); 解决办法
安装并登录成功。
三、数据库及数据库实例相关配置:
mysql数据库安装完成后,需要创建数据库实例,需要设置实例的编码,否则使用hibernate写数据时,可能报如下错误:
Hibernate: insert into Operlog (operCon, operIp, operName, operRes, operSql, operTime, operator) values (?, ?, ?, ?, ?, ?, ?) - SQL Error: 1366, SQLState: HY000 - Incorrect string value:

不敏感:无论大写、小写,只要是同一个字母,都认为一样,敏感相反。
/usr/my.cnf配置文件中[mysqld]节点下属性lower_case_table_names的含义:
设置为0:表名以大写方式存储,比较时也是大小写敏感。
设置为1:表名以小写方式存储,比较时大小写不敏感。
设置为2:表名按照给定字符串存储,比较时按小写方式比较。
windows、Mac OS x中由于文件名大小写不敏感,因次windows、mac osx中不能设置为0
windows中默认为 1
mac os x中默认为2
因此我们在linux中设置1即可。
vi /usr/my.cnf
# For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html [mysqld] # Remove leading # and set to the amount of RAM for the most important data # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%. # innodb_buffer_pool_size = 128M # Remove leading # to turn on a very important data integrity option: logging # changes to the binary log between backups. # log_bin # These are commonly set, remove the # and set as required. # basedir = ..... # datadir = ..... # port = ..... # server_id = ..... # socket = ..... # Remove leading # to set options mainly useful for reporting servers. # The server defaults are faster for transactions and fast SELECTs. # Adjust sizes as needed, experiment to find the optimal values. # join_buffer_size = 128M # sort_buffer_size = 2M # read_rnd_buffer_size = 2M sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES lower_case_table_names=1
service mysql restart
3.2、建库时指定编码:
建立数据库时指定编码
CREATE DATABASE IF NOT EXISTS my_db default charset utf8 COLLATE utf8_general_ci;
3.3、连接数据库时DBURL设置:
示例:
jdbc.url=jdbc:mysql://localhost:3306/myDbName?useUnicode=true&characterEncoding=UTF-8
完成上述三步即可测试插入、查询是否成功与乱码。
数据库相关编码查询(成功的):
[root@localhost home]# mysql -uroot -proot mysql> use myDbNamemysql> show variables like '%set%' -> ;+---------------------------------------+----------------------------+ | Variable_name | Value | +---------------------------------------+----------------------------+ | auto_increment_offset | 1 | | character_set_client | utf8 | | character_set_connection | utf8 | | character_set_database | utf8 | | character_set_filesystem | binary | | character_set_results | utf8 | | character_set_server | latin1 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | | innodb_monitor_reset | | | innodb_monitor_reset_all | | | optimizer_trace_offset | -1 | | performance_schema_setup_actors_size | 100 | | performance_schema_setup_objects_size | 100 | +---------------------------------------+----------------------------+ 14 rows in set (0.00 sec)
status命令:

四、mysql驱动版本不匹配问题:
在使用sqlyog(mysql驱动版本较低)操作mysql 6所建数据库时,可能会报出如下问题:
Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'OPTION SQL_SELECT_LIMIT=DEFAULT' at line 1 SQLState: 42000 ErrorCode: 1064
附:查询数据库版本:
mysql> select version(); +-----------+ | version() | +-----------+ | 5.6.17 | +-----------+ 1 row in set (0.00 sec) mysql>
五、如何卸载?
以下为rpm安装方式的mysql的卸载过程:
5.1、查看已经安装的mysql rpm包[root@localhost home]# rpm -qa | grep My MySQL-server-5.6.17-1.linux_glibc2.5 MySQL-client-5.6.17-1.linux_glibc2.5 [root@localhost home]#
5.2、停止mysql服务:
[root@localhost ~]# service mysql stop Shutting down MySQL.. [确定]
先卸载客户端:
[root@localhost ~]# rpm -e MySQL-client-5.6.17-1.linux_glibc2.5.i386 root@localhost ~]#
接着卸载其他相关包,如mysql开发包:
[root@localhost ~]# rpm -e MySQL-devel-5.6.17-1.linux_glibc2.5 [root@localhost ~]#
最后卸载服务端:
[root@localhost ~]# rpm -e MySQL-server-5.6.17-1.linux_glibc2.5 root@localhost ~]#
有时会出现一些错误或者警告: ... is needed by ... 这说明这个软件被其他软件需要,不能随便卸载 可以用rpm -e --nodeps强制卸载

蘋果公司最新發布的iOS18、iPadOS18以及macOSSequoia系統為Photos應用程式增添了一項重要功能,旨在幫助用戶輕鬆恢復因各種原因遺失或損壞的照片和影片。這項新功能在Photos應用的"工具"部分引入了一個名為"已恢復"的相冊,當用戶設備中存在未納入其照片庫的圖片或影片時,該相冊將自動顯示。 "已恢復"相簿的出現為因資料庫損壞、相機應用未正確保存至照片庫或第三方應用管理照片庫時照片和視頻丟失提供了解決方案。使用者只需簡單幾步

PHP處理資料庫連線報錯,可以使用下列步驟:使用mysqli_connect_errno()取得錯誤代碼。使用mysqli_connect_error()取得錯誤訊息。透過擷取並記錄這些錯誤訊息,可以輕鬆識別並解決資料庫連接問題,確保應用程式的順暢運作。

如何在PHP中使用MySQLi建立資料庫連線:包含MySQLi擴充(require_once)建立連線函數(functionconnect_to_db)呼叫連線函數($conn=connect_to_db())執行查詢($result=$conn->query())關閉連線( $conn->close())

可以透過使用gjson函式庫或json.Unmarshal函數將JSON資料儲存到MySQL資料庫中。 gjson函式庫提供了方便的方法來解析JSON字段,而json.Unmarshal函數需要一個目標類型指標來解組JSON資料。這兩種方法都需要準備SQL語句和執行插入操作來將資料持久化到資料庫中。

在Golang中使用資料庫回呼函數可以實現:在指定資料庫操作完成後執行自訂程式碼。透過單獨的函數新增自訂行為,無需編寫額外程式碼。回調函數可用於插入、更新、刪除和查詢操作。必須使用sql.Exec、sql.QueryRow或sql.Query函數才能使用回呼函數。

PHP連接資料庫指南:MySQL:安裝MySQLi擴展,建立連線(servername、username、password、dbname)。 PostgreSQL:安裝PgSQL擴展,建立連線(host、dbname、user、password)。 Oracle:安裝OracleOCI8擴展,建立連線(servername、username、password)。實戰案例:取得MySQL資料、PostgreSQL查詢、OracleOCI8更新記錄。

在C++中使用DataAccessObjects(DAO)函式庫連接和操作資料庫,包括建立資料庫連線、執行SQL查詢、插入新記錄和更新現有記錄。具體步驟為:1.包含必要的函式庫語句;2.開啟資料庫檔案;3.建立Recordset物件執行SQL查詢或操作資料;4.遍歷結果或依照特定需求更新記錄。

透過Go標準庫database/sql包,可以連接到MySQL、PostgreSQL或SQLite等遠端資料庫:建立包含資料庫連接資訊的連接字串。使用sql.Open()函數開啟資料庫連線。執行SQL查詢和插入操作等資料庫操作。使用defer關閉資料庫連線以釋放資源。
