MySQL常規巡檢

1、巡檢腳本

巡檢腳本包括三個文件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

2、下載巡檢腳本

3、腳本執行說明

一、inspection.conf 使用說明

使用說明：配置mysql登陸帳號信息以及mysql的標準配置

#============================================================================================================ #MySQL巡檢配置 #============================================================================================================ #mysql用戶名 MYSQL_USER=root #mysql用戶密碼 MYSQL_PASS='xxxxxxx' #mysql客戶端 MYSQL_COMM=mysql #備份路徑 BAK_PATH=/r2/bak_sql #mysql全局日誌 GLOBAL_LOG=`hostname`_global_`date +%Y%m%d`.txt #mycnf內容輸出 MYCNF=`hostname`_mycnf_`date +%Y%m%d`.txt #mysqltuner輸出日誌 MYSQLTUNER_LOG=`hostname`_mysqltuner_`date +%Y%m%d`.txt #檢查mysql標準配置日誌 #TANDARD_MYSQL_CONF=`hostname`_standard_`date +%Y%m%d`.txt #檢查mysql標準配置 standard_basedir=/usr/ standard_datadir=/r2/mysqldata/ standard_plugin=/usr/lib64/mysql/plugin/ standard_osmysqluser=mysql standard_log_error=/r2/mysqldata/error.log standard_pid=/r2/mysqldata/`hostname`.pid standard_socket=/r2/mysqldata/mysql.sock

二、inspection_mysql.sh 使用說明

inspection_mysql.sh

腳本簡述 :主腳本經過讀取inspection.conf 配置文件來執行，調用perl來執行 mysqltuner.pl來提供優化建議

三、mysqltuner.pl 使用說明

腳本簡述：這是mysql調優工具，給出一些基本的建議

• 單獨運行

./mysqltuner.pl --user=xxxxxx --pass='xxxxxx'

或者

./mysqltuner.pl 按照提示輸入帳號祕密

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)
