数据库备份 - automysqlback- Error: Dependency programs are missing. mysql ……没有找到？

昨天在Linux 服务器上做了一个的mysql数据库备份，备份很重要关键时候能救命。具体怎么备份这边就不多说了。文件已经免费上传了

	# This option sends a START TRANSACTION SQL statement to the server before dumping data. It is useful only with
	# transactional tables such as InnoDB, because then it dumps the consistent state of the database at the time
	# when BEGIN was issued without blocking any applications.
	#
	# When using this option, you should keep in mind that only InnoDB tables are dumped in a consistent state. For
	# example, any MyISAM or MEMORY tables dumped while using this option may still change state.
	#
	# While a --single-transaction dump is in process, to ensure a valid dump file (correct table contents and
	# binary log coordinates), no other connection should use the following statements: ALTER TABLE, CREATE TABLE,
	# DROP TABLE, RENAME TABLE, TRUNCATE TABLE. A consistent read is not isolated from those statements, so use of
	# them on a table to be dumped can cause the SELECT that is performed by mysqldump to retrieve the table
	# contents to obtain incorrect contents or fail.
	#CONFIG_mysql_dump_single_transaction='no'
	
	# http://dev.mysql.com/doc/refman/5.0/en/mysqldump.html#option_mysqldump_master-data
	# --master-data[=value]
	# Use this option to dump a master replication server to produce a dump file that can be used to set up another
	# server as a slave of the master. It causes the dump output to include a CHANGE MASTER TO statement that indicates
	# the binary log coordinates (file name and position) of the dumped server. These are the master server coordinates
	# from which the slave should start replicating after you load the dump file into the slave.
	#
	# If the option value is 2, the CHANGE MASTER TO statement is written as an SQL comment, and thus is informative only;
	# it has no effect when the dump file is reloaded. If the option value is 1, the statement is not written as a comment
	# and takes effect when the dump file is reloaded. If no option value is specified, the default value is 1.
	#
	# This option requires the RELOAD privilege and the binary log must be enabled.
	#
	# The --master-data option automatically turns off --lock-tables. It also turns on --lock-all-tables, unless
	# --single-transaction also is specified, in which case, a global read lock is acquired only for a short time at the
	# beginning of the dump (see the description for --single-transaction). In all cases, any action on logs happens at
	# the exact moment of the dump.
	# ==================================================================================================================
	# possible values are 1 and 2, which correspond with the values from mysqldump
	# VARIABLE=    , i.e. no value, turns it off (default)
	#
	#CONFIG_mysql_dump_master_data=
	
	# Included stored routines (procedures and functions) for the dumped databases in the output. Use of this option
	# requires the SELECT privilege for the mysql.proc table. The output generated by using --routines contains
	# CREATE PROCEDURE and CREATE FUNCTION statements to re-create the routines. However, these statements do not
	# include attributes such as the routine creation and modification timestamps. This means that when the routines
	# are reloaded, they will be created with the timestamps equal to the reload time.
	#
	# If you require routines to be re-created with their original timestamp attributes, do not use --routines. Instead,
	# dump and reload the contents of the mysql.proc table directly, using a MySQL account that has appropriate privileges
	# for the mysql database.
	#
	# This option was added in MySQL 5.0.13. Before that, stored routines are not dumped. Routine DEFINER values are not
	# dumped until MySQL 5.0.20. This means that before 5.0.20, when routines are reloaded, they will be created with the
	# definer set to the reloading user. If you require routines to be re-created with their original definer, dump and
	# load the contents of the mysql.proc table directly as described earlier.

	# Create differential backups. Master backups are created weekly at #$CONFIG_do_weekly weekday. Between master backups,

	# following structure
	# $filename 	md5sum	$md5sum	diff_id	$diff_id	rel_id	$rel_id
	# where each field is separated by the tabular character '\t'. The entries with $ at the beginning mean the actual values,
	# while the others are just for readability. The diff_id is the id of the differential or master backup which is also in
	# the filename after the last _ and before the suffixes begin, i.e. .diff, .sql and extensions. It is used to relate
	# differential backups to master backups. The master backups have 0 as $rel_id and are thereby identifiable. Differential
	# backups have the id of the corresponding master backup as $rel_id.

初步检查没有什么大问题，监测了一下定时任务
# crontab -l

定时任务没啥问题。决定通过执行备份命令方式进行排查问题
# /usr/local/bin/automysqlbackup /etc/automysqlbackup/automysqlbackup.conf
界面提示：automysqlback- Error: Dependency programs are missing. mysql ……
应该是automysqlbackup启动程序没有找到mysql.

数当时建数据库用的是docker 容器的方式进行安装的，本地没有初始化导致MySQL没有将路径放在/usr/local/bin:/usr/bin:/bin:/usr/local/mysql/bin

解决思路：

1.先查服务器的mysql 通过命令
#ps -ef | grep mysqldump
2.查看docker
#docker ps 
3.全局查到 通过find 命令查找mysqldump
# find / -name 'mysqldump'

4.编辑/etc/automysqlbackup/automysqlbackup.conf 通过修改里面的path

注：if mysql and mysqldump are not located in /usr/local/bin:/usr/bin:/bin:/usr/local/mysql/bin 这边其实有告诉我们如果msyql安装时没有将文件初始化到/usr/local/时可自行调整到指定目录。
