mysql5.6运行一段时间之后网站页面出现乱码解决办法

mysql5.6运行一段时间之后网站页面出现乱码，怎么都打不开，经过排查之后，知道是数据库默认字符集出问题了，在此分享给大家经验。

在mysql5.6配置文件：my.ini 找到：

添加如下内容：

[client]
# Client characterset and Connection characterset
default-character-set=utf8
[mysqld]
# Server characterset and Database characterset
character_set_server=utf8

　　这个是我全部配置：

# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
# *** default location during install, and will be replaced if you
# *** upgrade to a newer version of MySQL.

[mysqld]
#skip-grant-tables
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 256M

# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin

# These are commonly set, remove the # and set as required.
