linux修改配置文件解决mysql中文乱码和指定数据库存储引擎

%character_set%‘; +--------------------------+----------------------------+ | Variable_name | Value | +--------------------------+----------------------------+ | character_set_client | latin1 | | character_set_connection | latin1 | | character_set_database | latin1 | | character_set_filesystem | binary | | character_set_results | latin1 | | character_set_server | latin1 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | +--------------------------+----------------------------+ 8 rows in set (0.00 sec)

 

　　修改配置文件：

[root@VM_0_14_centos ~]# vi /etc/my.cnf 

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

#字符集指定为utf8
character-set-server=utf8

#字符集的校对规则为utf8
collation-server=utf8_general_ci

#存储引擎
default-storage-engine=InnoDB

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

[client]
default-character-set=utf8

[mysql]
default-character-set=utf8

 

　　标黄的都是新增的配置，接着保存好配置文件，重启mysql让设置生效：

[root@centos ~]# service mysqld restart
Stopping mysqld:  [  OK  ]
Starting mysqld:  [  OK  ]

 　　

　　登陆mysql，看下存储引擎：

mysql> show variables like ‘%storage_engine%‘;
+----------------+--------+
| Variable_name  | Value  |
+----------------+--------+
| storage_engine | InnoDB |
+----------------+--------+
1 row in set (0.00 sec)

 

　　再看字符编码：

mysql> show variables like ‘%character_set%‘;
+--------------------------+----------------------------+
| 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     | utf8                       |
| character_set_system     | utf8                       |
| character_sets_dir       | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)

 

　　我们发现还有一个character_set_database是ISO-8859-1，改掉：

mysql> alter database `prize` character set utf8 collate utf8_general_ci;
Query OK, 1 row affected (0.00 sec)

mysql> show variables like ‘%character_set%‘;
+--------------------------+----------------------------+
| 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/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)

 

　　现在把老的乱码数据删掉，重新插入就可以展示了：
