一、什么是doDBA

doDBA工具是基于控制台的远程系统监视器。在远程系统上不需要特殊的软件。它从Linux和MySQL收集实时性能数据。并且可以生成一个执行文件来帮助您分析MySQL数据库。该程序是免费软件。doDBA是用go编写的。

二、下载与部署#

1.软件下载

#下载软件
[root@www.wulaoer.org ~]# wget https://raw.githubusercontent.com/dblucyne/dodba_tools/master/doDBA --no-check-certificate
#下载配置文件
[root@www.wulaoer.org ~]# wget https://raw.githubusercontent.com/dblucyne/dodba_tools/master/doDBA.conf --no-check-certificate

下载解压完成即可直接使用，不依赖任何环境。

使用帮助

The doDBA tools is a console-based remote system monitor.
that does not require special software on the remote system.
it collects real-time performance data from linux and MySQL.
And can generate a doing file to help you analyze the MySQL database.
This program is free software.doDBA is written in go.

Usage: doDBA [OPTIONS]
-help
Display this help. 显示此帮助
-c string
configuration file. (default "doDBA.conf") 使用什么配置文件（默认就是上面下载的那个）
-h string
Connect to host/IP. 连接目标主机
-sys
Print system info. 打印系统信息
-myall
Print system and mysql info. 打印系统和MySQL信息
-mysql
Print mysql info.只打印MySQL信息
-innodb
Print innodb info.打印innodb信息
-mytop
Print mysql prcesslist info , like top.打印MySQL processlist，类似top
-i duration
refresh interval in seconds. (default 1s)刷新间隔
-t int
mysql doing on Threads_running. (default 50)当MySQL Threads_running到达阈值时会输出 show processlist和showengine innodb status到dodba.log中 (默认50)
-hP string
Connect host port. (default "22")指定主机端口
-hp string
Connect host password.主机密码
-hu string
Connect host user. (default current user)连接用户
-mP string
Connect mysql port. (default "3306")MySQL端口
-mp string
Connect mysql password.MySQL密码
-mu string
Connect mysql user.MySQL用户
-rds
Ignore system info.忽略linux信息
-log
Print to file by day.按照日期输出到日志文件
-nocolor
Print to nocolor.没有颜色输出

2.配置文件解析#

配置文件信息：

[root@www.wulaoer.org ~]# vim doDBA.conf
{
"Host":"192.168.0.35",
"Huser": "root",
"Hport": "22",
"Hpwd":  "123456",
"Muser": "dodba",
"Mpwd":  "dodba",
"Mport":"3306"
}

3.启动监控

[root@www.wulaoer.org ~]# ./doDBA -h 192.168.0.35 -myall -rds

建议将doDBA放在一台主机上去监控其他的MySQL

[root@www.wulaoer.org ~]# ./doDBA -h 192.168.0.35 -myall -rds

三、doDBA可选数据源#

一个 doDBA 进程同时只能配置一个数据源参数，配置2个及以上时，只能生效一个，参数有优先级的区别:mysql > innodb > myall > sys

1.mysql

[root@www.wulaoer.org ~]# ./doDBA -c doDBA.conf -mysql -log #启动监控
[root@www.wulaoer.org ~]# ls #生成的日志
192168035_dodba_mysql_20200729.log
[root@www.wulaoer.org ~]# cat 192168035_dodba_mysql_20200729.log

....
