免安装mysql修改root密码，有时出错？谢谢回复！在线等待

wang_lxiang

我是把noninstall的mysql放在我们的软件当中，安装的时候一起复制。
先注册系统服务：mysqld --install mysql
然后启动服务:net start mysql
接着修改密码：mysqladmin -uroot password 111111
可是执行到此处的时候，有时候会出错，有时候没有问题？请教各位是什么原因啊？
万分感谢！！

下面是my.ini：

#
# This is for a large system with memory = 512M where the system runs mainly
# MySQL.
#
# You can copy this file to
# /etc/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is C:\mysql\data) or
# ~/.my.cnf to set user-specific options.
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.

# The following options will be passed to all MySQL clients

# Replication Slave (comment out master section to use this)
#
# 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
#master-port     =  <port>

最让上郁闷的一点时，执行到这一句的时候有时候没有问题，有时候出现问题。真的很头疼，都好几天了，还是没有解决，希望知道原因的大侠帮帮忙啊？谢谢了

cenalulu

报的什么错呢？

wang_lxiang

mysqladmin:connect to server at 'localhost' failed
error:cat't connect to mysql server on 'localhost'<10061>'
check that mysqld is running on localhost
and that the port is 3309.you can check this by doing 'telnet localhost 3309'

请问露露这是什么原因啊？怎么有时候成功，有时候会这样呢？

聪明笨小孩

mysqladmin  -P3309 -uroot password 111111

端口是3309？

聪明笨小孩

重新启动机器看看，你安装了几个MYSQL ,曾经安装过吗？检查下 计算机服务管理里，启动时那个？

wang_lxiang

是的，我把端口号改为3309了。我每次安装后失败后，都会mysqld --remove mysql，再重启装。
执行到mysqladmin -uroot  password ，有时候成功，有时候失败。修改成功了，删除服务，重装后，密码仍为重装前密码，是不是没有清理干净？

cenalulu

报的这个错说明是mysql服务没起来，装好以后确认下mysql服务处于启动状态。
然后telnet一下3309端口，确认mysql是起在3309上，然后再改密码。
楼主的环境应该是windows吧？是的话注意下安全卫士360关掉。

至于删除重装后的密码不变，说明你只删除了程序文件，而没有把数据文件删除。

wang_lxiang

是的。我的环境是windows。
可为什么使用了net start mysql却没有启动mysql服务呢？为什么有的时候是成功的，有的时候却失败了呢？
