MYSQL-skip-networking
1、跳过tcp/ip协议通信：# The TCP/IP Port the MySQL Server will listen on
port=3306
#log_output=TABLE
skip-networking#添加这一行
然后重启服务
2、测试连接：
C:\Documents and Settings\Administrator>mysql -u root -p
Enter password:
ERROR 2003 (HY000): Can't connect to MySQL server on 'localhost' (10061)
可以看出连接mysql失败，那么我们没有了tcp/ip协议我们在本地如何连接呢？
3、通过参数--protocol=pipe：
C:\Documents and Settings\Administrator>mysql --protocol=pipe -u root -
Enter password:
ERROR 2017 (HY000): Can't open named pipe to host: .pipe: MySQL (2)
可以看出连接失败了！
那么我们试试添加：enable-named-pipe
如：
# The TCP/IP Port the MySQL Server will listen on
port=3306
#log_output=TABLE
skip-networking
enable-named-pipe
4、然后登陆：
C:\Documents and Settings\Administrator>mysql --protocol=pipe -u root -p
Enter password:

可以看出可以登陆了！
4、
my.ini配置:
# The TCP/IP Port the MySQL Server will listen on
port=3306
#log_output=TABLE
skip-networking
shared_memory=ON
#enable-named-pipe
测试：
TCP/IP连接：
C:\Documents and Settings\Administrator>mysql -uroot -pw123123

mysql 端口监听问题
mysql 启动了，用 localhost 可以连接，但是用 127.0.0.1 不能连接。可能的原因是
① mysql为了增强安全性而跳过了端口监听，查看方法：
用mysql> SHOW VARIABLES;或者 mysql> SHOW VARIABLES LIKE 'skip_networking';
查看skip_networking，如果skip_networking=ON ，则到my.ini 中将 skip_networking 注释掉；
② 如果显示的是 OFF 则可能是绑定了监听 IP ，在设置文件中查找 bind_address ,如果有的话将其改为 bind_address= 0.0.0.0
③ 可能是权限问题，这个就上网找吧。。。
