最近有个小项目需要修改MySQL的字符集，所以按照网上的教程修改，发现MySQL不能启动
然后网上说是，/etc/my.cnf设置的问题，貌似项目中MySQL是用rpm安装的，在etc中没有my.cnf，所以按照晚上的教程自己写了一个my.cnf放在etc文件夹下，启动失败。删除my.cnf，MySQL服务启动成功。
所以应该是my.cnf的设置问题，打开/var/lib/mysql/localhost.localdomain.err文件，查看发现了错误，/usr/bin/mysqld: unknown variable 'default-character-set=utf8' 注释my.cnf中的这条语句，启动成功，上网查找，发现网上有大牛说，用character_set_server=utf8来取代 default-character-set=utf8
MySQL服务重启成功，查看字符集，修改成功
