利用shell+短信实现简单MySQL双向同步监控
原理、脚本都很简单,就是截取同步状态的Slave_IO_Running和Slave_SQL_Running两个值是否都为Yes。如果其中不是,就发短信报警。

[root@mysqlb script]# cat Check_Mysql_Slave_Replication.sh
#!/bin/sh
. /etc/profile
db_user=reed
db_paasswd=reed
LogPath=/root/script/Check_Mysql_Slave_Replication_Log
[ ! -d $LogPath ] && mkdir -p $LogPath
cd $LogPath
Slave_IO_Running=$(/usr/local/mysql/bin/mysql -u$db_user -p$db_paasswd -e"show slave status \G"|grep 'Slave_IO_Running'|cut -d':' -f 2|cut -d' ' -f 2)
Slave_SQL_Running=$(//usr/local/mysql/bin/mysql -u$db_user -p$db_paasswd -e"show slave status \G"|grep 'Slave_SQL_Running'|cut -d':' -f 2|cut -d' ' -f 2)
FUNC()
{
echo "[INFO]$(date +'%F %T') begin to monitor mysql replication..."
if [ "$Slave_IO_Running" == "Yes" ] && [ "$Slave_SQL_Running" == "Yes" ];then
echo "[INFO]$(date +'%F %T') mysql replication is ok!"
else
echo "[ERROR]$(date +'%F %T') fuck!mysql24 replication is failed..."
#调用自己写的发短信脚本
/root/script/info_takeok.sh "fuck!mysql24 replication is failed"
fi
}
FUNC >>Check_Mysql_Slave_Replication$(date +'%F').log
最后写到crontab里面,一分钟检测一次。

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.

Yes, MySQL can be installed on Windows 7, and although Microsoft has stopped supporting Windows 7, MySQL is still compatible with it. However, the following points should be noted during the installation process: Download the MySQL installer for Windows. Select the appropriate version of MySQL (community or enterprise). Select the appropriate installation directory and character set during the installation process. Set the root user password and keep it properly. Connect to the database for testing. Note the compatibility and security issues on Windows 7, and it is recommended to upgrade to a supported operating system.

The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values and pointers to data rows, and is suitable for non-primary key column queries.

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

In MySQL database, the relationship between the user and the database is defined by permissions and tables. The user has a username and password to access the database. Permissions are granted through the GRANT command, while the table is created by the CREATE TABLE command. To establish a relationship between a user and a database, you need to create a database, create a user, and then grant permissions.
