标签：character 配置文件 specified mysql share
mysql: Character set ‘utf8mb4‘ is not a compiled character set and is not specified in the ‘/usr/share/mysql/charsets/Index.xml‘ file
报错的解决方法
1、由于日常程序使用了字符集utf8mb4，为了避免每次更新时，set names utf8mb4，就把配置文件改了，如下：
增加了mysql客户端的默认字符集设置
[root@~]# vim /etc/my.cnf
#my.cnf
[client]
port = 3306
socket = /home/mysql/mysql.sock
default-character-set=utf8mb4
2、重启mysql服务
[root@~]# service mysql restart
Shutting down MySQL (Percona Server).... SUCCESS!
Starting MySQL (Percona Server).... SUCCESS!
3、进入mysql时，报错：
[root@~]# mysql
Logging to file ‘/home/mysql/query.log‘
mysql: Character set ‘utf8mb4‘ is not a compiled character set and is not specified in the ‘/usr/share/mysql/charsets/Index.xml‘ file
4、百度了一个解决方法：
[root@~]# vim /etc/my.cnf
#my.cnf
[client]
port = 3306
socket = /home/mysql/mysql.sock
character-sets-dir=/usr/local/Percona-Server-5.5.20-rel24.1-217.Linux.x86_64/share/charsets
default-character-set=utf8mb4
5、重启mysql后，还是报同样的错
[root@~]# service mysql restart
Shutting down MySQL (Percona Server).... SUCCESS!
Starting MySQL (Percona Server).... SUCCESS!
[root@~]# mysql
Logging to file ‘/home/mysql/query.log‘
mysql: Character set ‘utf8mb4‘ is not a compiled character set and is not specified in the ‘/usr/share/mysql/charsets/Index.xml‘ file
6、经查mysql命令调用的是/usr/bin下的
[root@ ~]# ls /usr/bin/ |grep mysql
msql2mysql
mysql
mysqlaccess
mysqladmin
mysqlbinlog
mysqlcheck
mysql_config
mysqld_multi
mysqld_safe
mysqldump
mysql_find_rows
mysqlimport
mysqlshow
mysqlslap
mysql_waitpid
7、发现该服务器上在我安装mysql5.5.20之前，安装过mysql5.1的客户端
[root@ ~]# rpm -qa |grep mysql
mysql-5.1.73-3.el6_5.x86_64
mysql-libs-5.1.73-3.el6_5.x86_64
8、将mysql5.5.20下的mysql命令全部拷贝到/usr/bin目录下
\cp /usr/local/Percona-Server-5.5.20-rel24.1-217.Linux.x86_64/bin/* /usr/bin/
9、5.5.20相比5.1版本增加了不少命令
[root@~]# ls /usr/bin/ |grep mysql
msql2mysql
mysql
mysqlaccess
mysqlaccess.conf
mysqladmin
mysqlbinlog
mysqlbug
mysqlcheck
mysql_client_test
mysql_config
mysql_convert_table_format
mysqld
mysqld_multi
mysqld_safe
mysqldump
mysqldumpslow
mysql_find_rows
mysql_fix_extensions
mysqlhotcopy
mysqlimport
mysql_install_db
mysql_plugin
mysql_secure_installation
mysql_setpermission
mysqlshow
mysqlslap
mysqltest
mysql_tzinfo_to_sql
mysql_upgrade
mysql_waitpid
mysql_zap
10、修改完后，再次使用进入mysql，OK~
