ubuntu 安装mysql及修改编码

  643  netstat -tap | grep mysql
  645  apt-get install mysql-server mysql-client
  646  netstat -tap | grep mysql
  647  mysql -u root -p 
  648  vim /etc/mysql/my.cnf
  配置编码[增加蓝色，粗体]

[client]
default-character-set=utf8
port            =
socket          = /var/run/mysqld/mysqld.sock
# Here is entries for some specific programs
# The following values assume you have at least 32M ram

# This was formally known as [safe_mysqld]. Both versions are currently parsed.
[mysqld_safe]
socket          = /var/run/mysqld/mysqld.sock
nice            = 

[mysqld]
#
# * Basic Settings
#
character-set-server=utf8      注解：这里不能写default-character-set=utf8  否则启动mysql会报错~
user            = mysql
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
port            =
basedir         = /usr
datadir         = /var/lib/mysql
tmpdir          = /tmp
lc-messages-dir = /usr/share/mysql
skip-external-locking

查看是否更改了编码：

mysql> show variables like 'character%';
