解析mysql 5.5字符集问题

安装了个5.5版本的mysql，字符集出现了问题，之前的mysql服务器都是通过在my.cnf配置文件中进行配置便可，可是今儿怎么着都不行一直报错：

当时系统中也没有配置错误日志，所以只能是先配置下错误日志的位置，看看到底是哪里出错了：

复制代码 代码如下:

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
log-error=/var/log/mysql/error.log
lc-messages-dir = /usr/share/mysql
skip-external-locking
default-character-set=utf8

复制代码 代码如下:

[ERROR] /usr/sbin/mysqld: unknown variable 'default-character-set=utf8'

具体请看：

把default-character-set=utf8 改成： character-set-server=utf8就可以了。

复制代码 代码如下:

root@chenDBA:/etc/mysql# vim my.cnf
root@chenDBA:/etc/mysql# service mysql start
mysql start/running, process 5904
root@chenDBA:/etc/mysql# mysql -uroot -p
Enter password:
mysql> show variables like 'character%';
