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：
1CentOS Linux release 7.7.1908 (Core)

数据库：
1docker run -d -p 3306:3306 --env MYSQL_ROOT_PASSWORD=123456 mysql
03. 安装 mysqltuner
1wget http://mysqltuner.pl/ -O mysqltuner.pl
2wget https://raw.githubusercontent.com/major/MySQLTuner-perl/master/basic_passwords.txt -O basic_passwords.txt
3wget https://raw.githubusercontent.com/major/MySQLTuner-perl/master/vulnerabilities.csv -O vulnerabilities.csv
04. 使用 mysqltuner
1perl 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
1Can'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
1 yum install 'perl(Data::Dumper)'

1510 MySQL was started within the last 24 hours - recommendations may be inaccurate
1511 Reduce your overall MySQL memory footprint for system stability
1512 Dedicate this server to your database for highest performance.
1513 Reduce or eliminate unclosed connections and network issues
1514 Before changing innodb_log_file_size and/or innodb_log_files_in_group read this: https://bit.ly/2TcGgtU
1515Variables to adjust:
1516 *** MySQL's maximum memory usage is dangerously high ***
1517 *** Add RAM before increasing MySQL buffer variables ***
1518 vm.swappiness <= 10 (echo 10 > /proc/sys/vm/swappiness)
1519 fs.aio-max-nr > 1M (echo 1048576 > /proc/sys/fs/aio-max-nr)
1520 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
