[原创]doDBA工具使用详解
目录
1.简介
- doDBA 工具是一个基于命令行的远程系统监控工具。不依赖远程服务器的软件运行。它能实时的收集Linux和MySQL的性能数据。并可以生成一个执行文件来帮助您分析MySQL数据库。
- 这个程序是免费软件。
- doDBA是用go编写的。
2.下载
wget https://raw.githubusercontent.com/dblucyne/dodba_tools/master/doDBA --no-check-certificate
wget https://raw.githubusercontent.com/dblucyne/dodba_tools/master/doDBA.conf --no-check-certificate
chmod +x doDBA
或者
git pull https://github.com/dblucyne/dodba_tools
3.使用帮助
./doDBA -help
-help # 显示帮助
-c string # 指定配置文件 (default "doDBA.conf")
-h string # 连接的 host/IP
-sys # 打印Linux的信息
-myall # 打印Linux和MySQL的信息
-mysql # 打印MySQL的信息
-innodb # 打印InnoDB存储引擎的信息
-mytop # 打印MySQL processlist，类似top
-i <duration> # 刷新间隔的秒数 (默认1s)
-t <int> #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> # 主机端口 (默认 "22")
-hp <string> # 主机密码
-hu <string> # 主机用户 (默认 "root")
-mP <string> # MySQL端口 (默认 "3306")
-mp <string> # MySQL密码
-mu <string> # MySQL用户
-rds # 忽略Linux信息
-log # 按照日期输出到日志文件
-nocolor # 不加颜色输出
4.配置
4.1.模板
cat doDBA.conf
{
"Host":"",
"Huser": "root",
"Hport": "22",
"Hpwd": "",
"Muser": "dodba",
"Mpwd": "dodba",
"Mport":"3306"
}
4.2.启动命令
./doDBA -c=doDBA.conf
5.部署流程
5.1.下载
5.2.选定被监控主机
5.3.在被监控主机上添加Linux用户、MySQL 用户
Linux：
groupadd dodba
useradd dodba -g dodba
echo xxxx | passwd dbdba --stdin
MySQL：
create user dodba@’xxx.xxx.xxx.%’ identified by ‘dodba’;
grant process on *.* to dodba@'xxx.xxx.xxx.%';
5.4.配置SSH互信
5.5.配置doDBA配置文件，并修改对应参数
5.6.创建日志目录，按照业务、主机、实例等分别创建
mkdir -p /data/doDBA_log/piwik/mysql{1,2}_log/{myall,innodb}
5.7.启动doDBA
- 建议将doDBA安装在某一台主机上，监控其他被监控主机及数据库
5.7.1. 启动脚本，配置了 myall 和 innodb 数据源
cat start_doDBA.sh
#!/bin/bash
host_ip=("10.10.xx.xx")
INST_NAME="xxx"
data_source=("myall","innodb")
for IP in ${host_ip[@]}
for SRC in ${data_source[@]}
do
cd /data/doDBA_log/${inst_name}/mysql1_log/myall/
./doDBA -h ${IP} -c /data/doDBA_log/${INST_NAME}/mysql1_log/${SRC}/${INST_NAME}_doDBA.conf -$SRC -t=20 -log &
done
5.8.编辑kill doDBA和start doDBA脚本，已便每天生成一个日志文件。
cat kill_doDBA.sh
#!/bin/bash
ps -ef | grep doDBA | grep -v grep | awk '{print $2}' | xargs kill -9 >/dev/null 2>&1
5.9.配置crontab定时任务。
crontab -e
0 0 # # # sh kill_doDBA.sh
1 0 # # # sh start_doDBA.sh
6.数据源参数优先级
- 经过实际测试，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，说明参数有优先级的区别。
- 优先级如下：
- mysql > innodb > myall > sys
7.使用示例
7.1. 数据源：mysql
7.1.1. 启动命令
./doDBA -c doDBA.conf -mysql -log
7.1.2.doDBA 发送给 MySQL 的查询语句
