设置mysql监听外网ip
实现代码如下:

sudo vi /etc/my.cnf
bind-address = 127.0.0.1

设置mysql 字符集 charset
实现代码如下:

sudo vi /etc/my.cnf
在[mysqld]下面加入一行
character_set_server = utf8
在[mysql]下面加入一行
default-character-set = utf8
sudo /usr/local/mysql/support-files/mysql.server restart
mysql -uroot -p1
mysql> status
Server characterset: utf8
Db     characterset: utf8
Client characterset: utf8
Conn.  characterset: utf8
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/local/mysql/share/charsets/ |
+--------------------------+----------------------------------+
8 rows in set (0.00 sec)

mysql自动提示,命令自动完成,语法提示
实现代码如下:

sudo vi /etc/my.cnf
找到[mysql]
[mysql]
#no-auto-rehash
auto-rehash
sudo /usr/local/mysql/support-files/mysql.server restart
mysql -uroot -p1
use mysql
必须先use一个库,按tab键才能自动提示。

说明:之前写的文章太长,有重复,违反DRY,现在整理出来。

以上就是【mysql 常用设置 字符集编码、自动完成(自动提示)、监听外网ip】的全部内容了,欢迎留言评论进行交流!
