1. WSL ubuntu16 安裝

略

2. 安裝SQLAdvisor

一、拉代碼
git clone https://github.com/Meituan-Dianping/SQLAdvisor
或者下載在解壓

二、裝依賴

apt-get install cmake libaio-dev libffi-dev
apt-get install libglib2.0-dev

#先裝percona軟件源 https://www.percona.com/doc/percona-server/5.6/installation/apt_repo.html
wget https://repo.percona.com/apt/percona-release_latest.$(lsb_release -sc)_all.deb
dpkg -i percona-release_latest.$(lsb_release -sc)_all.deb
apt-get update
apt-get install libperconaserverclient18.1-dev

apt-get install g++

三、編譯依賴項sqlparser

cmake -DBUILD_CONFIG=mysql_release -DCMAKE_BUILD_TYPE=debug -DCMAKE_INSTALL_PREFIX=/usr/local/sqlparser ./
make && make install

四、安裝SQLAdvisor

cd  sqladvisor/
cmake -DCMAKE_BUILD_TYPE=debug ./
make

#報錯：
/usr/include/glib-2.0/glib/gtypes.h:32:24: fatal error: glibconfig.h: No such file or directory

#處理報錯
sudo find ./ iname "glibconfig.h"   2>/dev/null
/usr/lib/x86_64-linux-gnu/glib-2.0/include/glibconfig.h

#修改 CMakeLists.txt
#include_directories("/usr/lib64/glib-2.0/include") #依據find的路徑修改成下面
include_directories("/usr/lib/x86_64-linux-gnu/glib-2.0/include")

#從新編譯
rm CMakeCache.txt
cmake -DCMAKE_BUILD_TYPE=debug ./
make

3. 使用和測試

一、使用

# sqladvisor --help
用法：
  sqladvisor [OPTION…] sqladvisor

SQL Advisor Summary

幫助選項：
  -?, --help 顯示幫助選項

應用程序選項：
  -f, --defaults-file sqls file
  -u, --username username
  -p, --password password
  -P, --port port
  -h, --host host
  -d, --dbname database name
  -q, --sqls sqls
  -v, --verbose 1:output logs 0:output nothing

#使用，注意傳參空格
./sqladvisor -h xx -P xx -u xx -p 'xx' -d xx -q "sql" -v 1

$> cat sql.cnf
[sqladvisor]
username=xx
password=xx
host=xx
port=xx
dbname=xx
sqls=sql1;sql2;sql3....

cmd: ./sqladvisor -f sql.cnf -v 1

二、測試

aijie@DESKTOP-N85GQN8:~/dbplat/SQLAdvisor-master/sqladvisor$ ./sqladvisor -u ajtest -p ajtest -h 127.0.0.1 -P 3306 -d ajtest -q "select * from t1 where name = 'ccc';" -v 1
2019-05-15 16:41:28 14792 [Note] 第1步: 對SQL解析優化以後獲得的SQL:select `*` AS `*` from `ajtest`.`t1` where (`name` = 'ccc')
2019-05-15 16:41:28 14792 [Note] 第2步：開始解析where中的條件:(`name` = 'ccc')
2019-05-15 16:41:28 14792 [Note] show index from t1
2019-05-15 16:41:28 14792 [Note] show table status like 't1'
2019-05-15 16:41:28 14792 [Note] select count(*) from ( select `name` from `t1` FORCE INDEX( PRIMARY ) order by id DESC limit 1) `t1` where (`name` = 'ccc')
2019-05-15 16:41:28 14792 [Note] 第3步：表t1的行數:2,limit行數:1,獲得where條件中(`name` = 'ccc')的選擇度:1
2019-05-15 16:41:28 14792 [Note] 第4步：表t1 的SQL太逆天,沒有優化建議
2019-05-15 16:41:28 14792 [Note] 第5步: SQLAdvisor結束!
