1.簡介

• doDBA 工具是一個基於命令列的遠端系統監控工具。不依賴遠端伺服器的軟體執行。它能實時的收集Linux和MySQL的效能資料。並可以生成一個執行檔案來幫助您分析MySQL資料庫。
• 這個程式是免費軟體。
• doDBA是用go編寫的。

2.下載

wget 
wget 
chmod +x doDBA
或者
git pull

3.使用幫助

./doDBA -help-help  # 顯示幫助-c string  # 指定配置檔案 (default "doDBA.conf")-h string  # 連線的 host/IP-sys  # 列印Linux的資訊-myall  # 列印Linux和MySQL的資訊-mysql  # 列印MySQL的資訊-innodb  # 列印InnoDB儲存引擎的資訊-mytop  # 列印MySQL processlist，類似top-i <duration>  # 重新整理間隔的秒數 (預設1s)-t <int>  #當MySQL Threads_running到達閾值時會輸出 show processlist和showengine innodb status到dodba.log中 (預設50)-hP <string>  # 主機埠 (預設 "22")-hp <string>  # 主機密碼-hu <string>  # 主機使用者 (預設 "root")-mP <string>  # MySQL埠 (預設 "3306")-mp <string>  # MySQL密碼-mu <string>  # MySQL使用者-rds  # 忽略Linux資訊-log  # 按照日期輸出到日誌檔案-nocolor  # 不加顏色輸出

4.配置

4.1.模板

cat doDBA.conf{    "Host":"",    "Huser": "root",    "Hport": "22",    "Hpwd":  "",    "Muser": "dodba",    "Mpwd":  "dodba",    "Mport":"3306"}

4.2.啟動命令

./doDBA -c=doDBA.conf

5.部署流程

5.1.下載

5.2.選定被監控主機

5.3.在被監控主機上新增Linux使用者、MySQL 使用者

Linux：
groupadd dodba
useradd dodba -g dodbaecho 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配置檔案，並修改對應引數

5.6.建立日誌目錄，按照業務、主機、例項等分別建立

mkdir -p /data/doDBA_log/piwik/mysql{1,2}_log/{myall,innodb}

5.7.啟動doDBA

• 建議將doDBA安裝在某一臺主機上，監控其他被監控主機及資料庫

5.7.1. 啟動指令碼，配置了 myall 和 innodb 資料來源

cat start_doDBA.sh#!/bin/bashhost_ip=("10.10.xx.xx")
INST_NAME="xxx"data_source=("myall","innodb")for IP in ${host_ip[@]}for SRC in ${data_source[@]}docd /data/doDBA_log/${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.編輯kill doDBA和start doDBA指令碼，已便每天生成一個日誌檔案。

cat kill_doDBA.sh#!/bin/bashps -ef | grep doDBA | grep -v grep | awk '{print $2}' | xargs kill -9 >/dev/null 2>&1

5.9.配置crontab定時任務。

crontab -e
0 0 # # # sh kill_doDBA.sh1 0 # # # sh start_doDBA.sh

6.資料來源引數優先順序

• 經過實際測試，一個 doDBA 程式同時只能配置一個資料來源引數，配置2個及以上時，只能生效一個，說明引數有優先順序的區別。
• 優先順序如下：
  • mysql > innodb > myall > sys

7.使用示例

7.1. 資料來源：mysql

7.1.1. 啟動命令

./doDBA -c doDBA.conf -mysql -log

7.1.2.doDBA 傳送給 MySQL 的查詢語句

show global statuswhere
