mysql，發現都是亂碼，一堆問號，如下圖：

檢視mysql編碼

需要修改mysql編碼，開啟/etc/my.cnf 檔案

在下邊新增如下行

[client]
default_character_set=utf8
[mysqld]
collation_server = utf8_general_ci
character_set_server = utf8

修改後的/etc/my.cnf如下：

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user
 
=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

[client]
default_character_set=utf8
[mysqld]
collation_server = utf8_general_ci
character_set_server = utf8

再檢視如下

已經修改過來了，重啟， 再繼續查詢，能正常顯示中文漢字，搞定。
