MySQL常规巡检
一、巡检脚本
巡检脚本包括三个文件inspection.conf、inspection_mysql.sh、mysqltuner.pl
bash>ll
-rw-r--r-- 1 root root 994 Nov 1 16:33 inspection.conf
-rwxr-xr-x 1 root root 39221 Nov 1 15:26 inspection_mysql_v4.sh
-rwxr-xr-x 1 root root 219803 Nov 1 11:32 mysqltuner.pl
二、下载巡检脚本

三、脚本执行说明
1、inspection.conf 使用说明
使用说明：配置mysql登录账号信息以及mysql的标准配置

2、inspection_mysql.sh 使用说明
inspection_mysql.sh
脚本简述 :主脚本通过读取inspection.conf 配置文件来执行，调用perl来执行 mysqltuner.pl来提供优化建议

General recommendations:
Control warning line(s) into /r2/mysqldata/error.log file
Control error line(s) into /r2/mysqldata/error.log file
Set up a Secure Password for user@host ( SET PASSWORD FOR 'user'@'SpecificDNSorIp' = PASSWORD('secure_password'); )
Restrict Host for user@% to user@SpecificDNSorIp
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
When making adjustments, make tmp_table_size/max_heap_table_size equal
Reduce your SELECT DISTINCT queries which have no LIMIT clause
Increase table_open_cache gradually to avoid file descriptor limits
Read this before increasing table_open_cache over 64: http://bit.ly/1mi7c4C
Read this before increasing for MariaDB https://mariadb.com/kb/en/library/optimizing-table_open_cache/
This is MyISAM only table_cache scalability problem, InnoDB not affected.
See more details here: https://bugs.mysql.com/bug.php?id=49177
This bug already fixed in MySQL 5.7.9 and newer MySQL versions.
Beware that open_files_limit (50000) variable
should be greater than table_open_cache (1024)
Before changing innodb_log_file_size and/or innodb_log_files_in_group read this: http://bit.ly/2wgkDvS
Variables to adjust:
*** MySQL's maximum memory usage is dangerously high ***
*** Add RAM before increasing MySQL buffer variables ***
tmp_table_size (> 32M)
max_heap_table_size (> 32M)
table_open_cache (> 1024)
innodb_log_file_size should be (=512M) if possible, so InnoDB total log files size equals to 25% of buffer pool size.
innodb_buffer_pool_instances(=4)
