mysql 5.5字符集问题_MySQL

bitsCN.com
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：
[html] 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 结果查看了错误日志才发现是字符集的错误： [html] [ERROR] /usr/sbin/mysqld: unknown variable 'default-character-set=utf8' 居然不认识，上网上了找了下发现也有人遇到了，说是5.5中mysql不再使用default-character-set这种写法了。具体请看：http://dev.mysql.com/doc/refman/5.5/en/server-options.html#option_mysqld_default-character-set
把default-character-set=utf8 改成： character-set-server=utf8就可以了。 [html] 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%'; +--------------------------+----------------------------+ | 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) OK收工了。 作者 chen861201 bitsCN.com
