mysql优化工具mysqltuner
01. 介绍
https://github.com/major/MySQLTuner-perl
MySQLTuner是用Perl编写的脚本，可让您快速查看MySQL安装并进行调整以提高性能和稳定性。 检索当前配置变量和状态数据，并以简短的格式提供一些基本的性能建议。
在此最新版本中，MySQLTuner支持MySQL / MariaDB / Percona Server的约300个指标。
MySQLTuner持续更新，并且指标收集逐周增加，以支持许多配置，例如Galera Cluster，TokuDB，Performance模式，Linux OS指标，InnoDB，MyISAM，Aria等。
02. 环境初始化
服务器环境：
CentOS Linux release 7.7.1908 (Core)
model name : Intel(R) Xeon(R) CPU @ 2.00GHz
model name : Intel(R) Xeon(R) CPU @ 2.00GHz
physical id : 0
physical id : 0
MemTotal: 1882032 kB
数据库：
docker run -d -p 3306:3306 --env MYSQL_ROOT_PASSWORD=123456 mysql
03. 安装mysqltuner
wget http://mysqltuner.pl/ -O mysqltuner.pl
wget https://raw.githubusercontent.com/major/MySQLTuner-perl/master/basic_passwords.txt -O basic_passwords.txt
wget https://raw.githubusercontent.com/major/MySQLTuner-perl/master/vulnerabilities.csv -O vulnerabilities.csv
04. 使用mysqltuner
perl mysqltuner.pl --forcemem 1024 --host 10.170.0.6 --user root --pass root --buffers --dbstat --idxstat --sysstat --pfstat --tbstat --cvefile=./vulnerabilities.csv
如果执行报错
Can't locate Data/Dumper.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at ./mysqltuner.pl line 52
则需要安装perl依赖
yum install 'perl(Data::Dumper)'

-------- Recommendations ---------------------------------------------------------------------------
General recommendations:
setup swappiness lower or equals to 10
setup Max running number events greater than 1M
MySQL was started within the last 24 hours - recommendations may be inaccurate
Reduce your overall MySQL memory footprint for system stability
Dedicate this server to your database for highest performance.
Reduce or eliminate unclosed connections and network issues
Before changing innodb_log_file_size and/or innodb_log_files_in_group read this: https://bit.ly/2TcGgtU
Variables to adjust:
*** MySQL's maximum memory usage is dangerously high ***
*** Add RAM before increasing MySQL buffer variables ***
vm.swappiness <= 10 (echo 10 > /proc/sys/vm/swappiness)
fs.aio-max-nr > 1M (echo 1048576 > /proc/sys/fs/aio-max-nr)
innodb_log_file_size should be (=16M) if possible, so InnoDB total log files size equals to 25% of buffer pool size.
这边可以看出来结果还是很详细的，最后几行是根据当前的服务器数据库使用情况给出的优化建议
