1、跳過tcp/ip協議通信：
[mysqld]
# The TCP/IP Port the MySQL Server will listen on
port=3306
#log_output=TABLE
skip-networking #添加這一行
然後重啓服務
2、測試連接：
C:\Documents and Settings\Administrator>mysql -u root -p
Enter password:
ERROR 2003 (HY000): Can't connect to MySQL server on 'localhost' (10061)
可以看出連接mysql失敗，那麼我們沒有了tcp/ip協議我們在本地如何連接呢？
3、通過參數--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)
可以看出連接失敗了！
那麼我們試試添加：enable-named-pipe
如：
[mysqld]
# The TCP/IP Port the MySQL Server will listen on
port=3306
#log_output=TABLE
skip-networking
enable-named-pipe
4、然後登陸：
C:\Documents and Settings\Administrator>mysql --protocol=pipe -u root -p
Enter password:

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

mysql 端口監聽問題
mysql 啓動了，用 localhost 可以連接，但是用 127.0.0.1 不能連接。可能的原因是
① mysql爲了增強安全性而跳過了端口監聽，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 ，則到my.ini 中將 skip_networking 註釋掉；
② 如果顯示的是 OFF 則可能是綁定了監聽 IP ，在設置文件中查找 bind_address ,如果有的話將其改爲 bind_address= 0.0.0.0
③ 可能是權限問題，這個就上網找吧。。。
