Ubuntu 12.04,安装了MySQL,完了之后,更改了字符编译,就报错。感觉很郁闷。
环境:
- root@ubuntu:~# uname -a
- Linux ubuntu 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
使用的 apt-get install mysql-server安装的,然后改变了一下默认的字符集,在/etc/mysql/my.cnf里面的[mysqld]和[client]里加了
default-character-set=utf8,重启就不行了。
- root@ubuntu:~# service mysql start
- start: Job failed to start
看了系统日志,报了以下内容
- Jun 11 22:56:42 ubuntu kernel: [ 4051.584941] init: mysql main process (4021) terminated with status 7

纠结了很长时间,今天无意中测试,意外解决了问题,呵呵,不得不说,RP爆发。
配置文件如下
- root@ubuntu:/etc/mysql# cat /etc/mysql/my.cnf | grep -v '^#'
-
- [client]
- default-character-set=utf8 #这里其实不用指定的,如果要指定,要用这个指令。
- port = 3306
- socket = /var/run/mysqld/mysqld.sock
-
-
- [mysqld_safe]
- socket = /var/run/mysqld/mysqld.sock
- nice = 0
-
- [mysqld]
- character_set_server=utf8 #要使用这个命令,default-character-set=utf8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
- bind-address = 127.0.0.1
- key_buffer = 16M
- max_allowed_packet = 16M
- thread_stack = 192K
- thread_cache_size = 8
- myisam-recover = BACKUP
- query_cache_limit = 1M
- query_cache_size = 16M
- expire_logs_days = 10
- max_binlog_size = 100M
-
- [mysqldump]
- quick
- quote-names
- max_allowed_packet = 16M
-
- [mysql]
-
- [isamchk]
- key_buffer = 16M
-
- !includedir /etc/mysql/conf.d/
- root@ubuntu:/etc/mysql#
可以看出,在[client]和[myslqd]段中,设置字符编码使用的指令不一样。
然后重启mysql就可以了
- root@ubuntu:/etc/mysql# service mysql restart
- mysql stop/waiting
- mysql start/running, process 6981
- root@ubuntu:/etc/mysql# mysql -uroot -p
- Enter password:
