Log mysql operations

Keywords: MySQL MariaDB Google PHP

Now I want to compare the differences before and after php web page execution, but I still can't find better software
Add, delete, and change the kind that is recorded.

Then MySQL 5 is discovered by browsing the official documentation.1 has one Common Query Log .So try:

#cd /Applications/XAMPP/xamppfiles/bin
cd /Applications/XAMPP/xamppfiles/share/mysql
./mysql.server start --log=file_name.log

Then prompt:

Starting MySQL
.2017-12-16 14:51:44 546 mysqld_safe Logging to '/Applications/XAMPP/xamppfiles/var/mysql/MacBook-Air.local.err'.
2017-12-16 14:51:44 546 mysqld_safe Starting mysqld daemon with databases from /Applications/XAMPP/xamppfiles/var/mysql

Then I think about whether it's the MySQL version or not.
Try querying MySQL version.

#Start MySQL normally first
./mysql.server start
#Enter mysql
cd /Applications/XAMPP/xamppfiles/bin
./mysql -u root

You can see the system return

Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 3
Server version: 10.1.26-MariaDB Source distribution

Copyright (c) 2000, 2017, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

Wait, what is MariaDB?You can use Baidu.....

Then, to confirm whether it is MariaDB, execute

select version();


MariaDB [(none)]> select version();
| version()       |
| 10.1.26-MariaDB |
1 row in set (0.00 sec)

You can already see 10.1.26-MariaDB.

Then, all of the above is useless.The focus is here.
After a series of baidu.Don't ask me why google isn't (don't turn over walls if you can Baidu things)
Eureka MySQL configuration file my.cnf adds log parameter file error This article.

Then execute:

cd /Applications/XAMPP/xamppfiles/share/mysql
./mysql.server start --general_log_file=file_name.log

System Return:
