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            = 3306

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            = 0



[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            = 3306

basedir         = /usr

datadir         = /var/lib/mysql

tmpdir          = /tmp

lc-messages-dir = /usr/share/mysql

skip-external-locking
