我自己vi了一个/etc/my.cnf（打算加句max_connections=500）重起mysql后，客户端连接mysql就一直出现1045错误，服务器上的应用程序也拿不到连接，不知道怎么回事儿，后来删除了那个/etc/my.cnf错误依旧，现在通过cp /usr/share/mysql/my-medium.cnf /etc/my.cnf，还是同样错误 自己vi 的my.cnf代码
只是加了一句
max_connections=500 现在的my.cnf和/usr/share/mysql/my-medium.cnf完全一样 新情况
查看了mysql启动日志:
071210 1:24:06 [Warning] Found invalid password for user: 'root@%'; Ignoring user
071210 1:24:06 [Warning] Found invalid password for user: 'root@webserver'; Ignoring user
只是加了一句
max_connections=500 现在的my.cnf和/usr/share/mysql/my-medium.cnf完全一样 新情况
查看了mysql启动日志:
071210 1:24:06 [Warning] Found invalid password for user: 'root@%'; Ignoring user
071210 1:24:06 [Warning] Found invalid password for user: 'root@webserver'; Ignoring user
但肯定不是密码错误的问题，修改my.cnf之前都正常，期间密码没有更换过的
开始没有my.cnf,用的默认设置,现在copy /usr/share/mysql/my-medium.cnf /etc/my.cnf
代码和my-medium.cnf完全一样
现在问题是,有没有这个my.cnf,效果都是一个错误

#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
# the syntax is:
#
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
# where you replace <host>, <user>, <password> by quoted strings and
# <port> by the master's port number (3306 by default).
#
# Example:
#
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
# MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
# start replication for the first time (even unsuccessfully, for example
# if you mistyped the password in master-password and the slave fails to
# connect), the slave will create a master.info file, and any later
# change in this file to the variables' values below will be ignored and
# overridden by the content of the master.info file, unless you shutdown
# the slave server, delete master.info and restart the slaver server.
# For that reason, you may want to leave the lines below untouched
# (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id = 2
#
# The replication master for this slave - required
#master-host = <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user = <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password = <password>
#
# The port the master is listening on.
# optional - defaults to 3306

只改了my.cnf，导致了这个问题，删除了my.cnf问题依然存在
my.cnf删除后，mysql就按默认设置启动了把？
