mysql中文乱码解决

有时服务端显示中文正常，但在客户端却显示?乱码，

首先，系统字符集， echo $LANG

vi .bash_profile

export $LANG=en_us.utf8

另一个是，

mysql的，my.cnf中如下

mysqld和clients都要加上default-character-set=utf8少一不可。

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
default-character-set=utf8
#skip-networking
set-variable=max_allowed_packet=5M
#Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).
default-character-set=utf8
old_passwords=1
server_id = 2
log_bin = mysql-bin
log_bin-index=mysql-bin.index
auto_increment_offset=1
auto_increment_increment=1
#replay-log-index=slave-relay-bin.index
#replay-log=slave-replay-bin
# Disabling symbolic-links is recommended to prevent assorted security risks;
# to do so, uncomment this line:
# symbolic-links=0
