MYSQL使用心得(十二)----主从复制指定二进制日志位置相关命令
show slave status \G的具体含义
Slave_IO_Running: 表示从库是否复制了binlog
Slave_SQL_Running: 表示从库复制的binlog是否在从库上执行
本机查看时间点的最后结束日志位置
./mysqlbinlog --start-datetime='2013-12-08 20:14:00' --stop-datetime='2013-12-08 20:16:00' /data0/search/mysql/log/mysql-bin.000008
远程机器查看日志,需要输入用户名,密码,IP
mysqlbinlog --start-datetime='2013-12-09 00:14:00' --stop-datetime='2013-12-09 20:10:00' --force-read --read-from-remote-server --host=192.168.56.2 -urepl -prepl mysql-bin.000001
复制到指定位置
start slave until master_log_file='mysql-bin.000001',master_log_pos=977;
判断slave是否同步到面指定的位置,语句会阻塞直到到达指定的位置,语句就返回。master和IO线程肯定会执行了,不影响他们的更新或者同步
select master_pos_wait('mysql-bin.000001',977);
基本思路
首先stop复制
stop slave;
然后复制到当天最后时间点
start slave until \
master_log_file='mysql-bin.000001',\
master_log_pos=977;
查看状态
Slave_IO_Running: Yes
Slave_SQL_Running: No
判断slave是否同步到面指定的位置,语句会阻塞直到到达指定的位置,语句就返回。master和IO线程肯定会执行了,不影响他们的更新或者同步
select master_pos_wait('mysql-bin.000001',977);

Stored procedures are precompiled SQL statements in MySQL for improving performance and simplifying complex operations. 1. Improve performance: After the first compilation, subsequent calls do not need to be recompiled. 2. Improve security: Restrict data table access through permission control. 3. Simplify complex operations: combine multiple SQL statements to simplify application layer logic.

The working principle of MySQL query cache is to store the results of SELECT query, and when the same query is executed again, the cached results are directly returned. 1) Query cache improves database reading performance and finds cached results through hash values. 2) Simple configuration, set query_cache_type and query_cache_size in MySQL configuration file. 3) Use the SQL_NO_CACHE keyword to disable the cache of specific queries. 4) In high-frequency update environments, query cache may cause performance bottlenecks and needs to be optimized for use through monitoring and adjustment of parameters.

The reasons why MySQL is widely used in various projects include: 1. High performance and scalability, supporting multiple storage engines; 2. Easy to use and maintain, simple configuration and rich tools; 3. Rich ecosystem, attracting a large number of community and third-party tool support; 4. Cross-platform support, suitable for multiple operating systems.

The steps for upgrading MySQL database include: 1. Backup the database, 2. Stop the current MySQL service, 3. Install the new version of MySQL, 4. Start the new version of MySQL service, 5. Recover the database. Compatibility issues are required during the upgrade process, and advanced tools such as PerconaToolkit can be used for testing and optimization.
