Linux学习笔记之——ubuntu中mysql修改编码utf8

摘要:使用apt-get 命令安装的mysql默认不是utf8、在这里记录一下如何将编码修改成utf8。

一:查看mysql版本

1.1 mysql –V

在终端界面输入上面命令、显示如下:

                mysql  Ver 14.14 Distrib 5.5.35, fordebian-linux-gnu (x86_64) using readline 6.2

1.2 status

a) 登录mysql

                mysql –uroot –ppassword

b) 输入如下命令:

                status
                #会有如下显示:                --------------                mysql  Ver 14.14 Distrib5.5.35, for debian-linux-gnu (x86_64) using readline 6.2                 Connection id:          45                Current database:                Current user:           root@localhost                SSL:                    Not inuse                Current pager:          stdout                Using outfile:          ''                Using delimiter:        ;                Server version:        5.5.35-0ubuntu0.12.04.2 (Ubuntu)                Protocol version:       10                Connection:            Localhost via UNIX socket                Server characterset:    latin1                Db     characterset:    latin1                Client characterset:    utf8                Conn.  characterset:    utf8                UNIX socket:           /var/run/mysqld/mysqld.sock                Uptime:                 1 hour15 min 13 sec                 Threads: 1  Questions:609  Slow queries: 0  Opens: 421 Flush tables: 1  Open tables:41  Queries per second avg: 0.134                --------------

1.3 selectversion();

a) 登录mysql

                mysql –uroot –ppassword

b) 输入如下命令:

                select version();                #会有如下显示:                 +-------------------------+                | version()               |                +-------------------------+                | 5.5.35-0ubuntu0.12.04.2 |                +-------------------------+                1 row in set (0.00 sec)

二:查看mysql编码

2.1 登录mysql

a) 输入命令:

                mysql  –uroot  –p

b) 输入密码:

                password

2.2 查看mysql编码

                show variables like '%character%';                #会有如下显示:                +--------------------------+----------------------------+                | Variable_name            | Value                      |                +--------------------------+----------------------------+                | character_set_client     | utf8                       |                | character_set_connection | utf8                       |                |character_set_database   | latin1                     |                | character_set_filesystem | binary                     |                | character_set_results    | utf8                       |                |character_set_server     | latin1                     |                | character_set_system     | utf8                       |                | character_sets_dir       | /usr/share/mysql/charsets/ |                +--------------------------+----------------------------+                8 rows in set (0.00 sec)

三:修改mysql编码

上面步骤中可以看出红色的部分的编码——latin1

3.1 修改mysql的配置文件——/etc/mysql/my.cnf:

a) 打开mysql配置文件:

                vim/etc/mysql/my.cnf

b) 在[client]下追加:

                default-character-set=utf8

c) 在[mysqld]下追加:

                character-set-server=utf8

d) 在[mysql]下追加:

                default-character-set=utf8

e) 保存并退出

3.2 重启mysql服务

下面两个任何一个都可以:

                servicemysql restart                /etc/init.d/mysqlrestart

3.3 查看mysql编码是否修改成功

a) 登录mysql

b) 输入:

                show variables like '%character%';                #会有如下显示:                +--------------------------+----------------------------+                | Variable_name            | Value                      |                +--------------------------+----------------------------+                | character_set_client     | utf8                       |                | character_set_connection | utf8                       |                | character_set_database   | utf8                       |                | character_set_filesystem | binary                     |                | character_set_results    | utf8                       |                | character_set_server     | utf8                       |                | character_set_system     | utf8                       |                | character_sets_dir       |/usr/share/mysql/charsets/ |                +--------------------------+----------------------------+

则修改成功!
