本文记录了在使用mysqld_reportstop命令时遇到的MySQL无法停止问题，并详细展示了错误日志及my.cnf配置文件的内容。通过调整配置文件中的密码参数，成功解决了连接失败的问题。

今天在尝试运行mysqld_report stop的时候，发现无法停止mysql，日志中的错误如下

Stopping MySQL servers

mysqladmin: [Warning] Using a password on the command line interface can be insecure.
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: YES)'
mysqladmin: [Warning] Using a password on the command line interface can be insecure.
mysqladmin: connect to server at 'localhost' failed

mysqladmin: [Warning] Using a password on the command line interface can be insecure.

mysqld_multi log file version 2.16; run: Tue Jan 17 14:19:01 2017

可以看出，肯定是使用mysqladmin无法登录的问题。

但是，我的my.cnf配置文件中，已经指定了user和password，整个文件内容如下

[client]
port=3306
socket=/tmp/mysql.sock
 

[mysqld_multi]
user=root
password=root
mysqld=/usr/local/mysql/bin/mysqld_safe
mysqladmin=/usr/local/mysql/bin/mysqladmin
log=/home/mysql/mysqld_multi.log


[mysqld]
basedir=/usr/local/mysql
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES


[mysqld3306]  
mysqld=mysqld  
mysqladmin=mysqladmin  
datadir=/home/mysql/mysql3306/data  
port=3306  
server_id=3306  
socket=/tmp/mysql3306.sock  
log-output=file  
slow_query_log = 1  
long_query_time = 1  
slow_query_log_file = /home/mysql/mysql3306/log/slow.log  
log-error = /home/mysql/mysql3306/log/error.log  
binlog_format = mixed  
log-bin = /home/mysql/mysql3306/log/mysql3306_bin



[mysqld3307]
mysqld=mysqld
mysqladmin=mysqladmin
datadir=/home/mysql/mysql3307/data
port=3307
server_id=3307
socket=/tmp/mysql3307.sock
log-output=file
slow_query_log = 1
long_query_time = 1
slow_query_log_file = /home/mysql/mysql3307/log/slow.log
log-error = /home/mysql/mysql3307/log/error.log
binlog_format = mixed
log-bin = /home/mysql/mysql3307/log/mysql3307_bin




[mysqld3308]
mysqld=mysqld
mysqladmin=mysqladmin
datadir=/home/mysql/mysql3308/data
port=3308
server_id=3308
socket=/tmp/mysql3308.sock
log-output=file
slow_query_log = 1
long_query_time = 1
slow_query_log_file = /home/mysql/mysql3308/log/slow.log
log-error = /home/mysql/mysql3308/log/error.log
binlog_format = mixed
log-bin = /home/mysql/mysql3308/log/mysql3308_bin

其实，此时的配置有问题不对“password=root”应该改为“pass=root”,文件如下

[client]
port=3306
socket=/tmp/mysql.sock
 

[mysqld_multi]
user=root
pass=Abcd@1234
mysqld=/usr/local/mysql/bin/mysqld_safe
mysqladmin=/usr/local/mysql/bin/mysqladmin
log=/home/mysql/mysqld_multi.log

slow_query_log = 1  
long_query_time = 1  
slow_query_log_file = /home/mysql/mysql3306/log/slow.log  
log-error = /home/mysql/mysql3306/log/error.log  
binlog_format = mixed
