-bash : mysqldump: command not found
-bash : mysqlbinlog:command not found
First you have to know the full path of the mysql command or mysqldump command, you can use the find command to find it
Find / -name mysql -print
My mysql path is: /usr/local/mysql/bin/mysql, and then map a link to the /usr/bin directory, which is equivalent to creating a link file
ln -fs /usr/local /mysql/bin/mysql /usr/bin
Similarly: ln -s /usr/local/mysql/bin/mysqlbinlog /usr/bin
Before 5.7:
modify the my.cnf file and add log-bin=my-bin(my. The location of cnf is checked according to the path of your own installation)
# vi /usr/local/mysql/my.cnf
log-bin=my-bin #my-bin is the name of the bin-log file, you can customize the file name
or Customize the location where bin-log is stored. By default, it is in the mysql data directory, such as
log-bin=/mysql/data/my-bin
Note: The permissions of the /mysql/data folder require mysql.
The default is to have mysql-bin.00001 under /mysql/data/...
After modification, you need to restart mysql
# service mysql restart
View the mysql- bin.00001 log file :
mysqlbinlog mysql0bin.00001 |less For

You can use at to find the location, time, etc.
If you delete the database library or table, you can use mysql-bin.000012 to restore the document. View based on start/end time
with mysqlbinlog tool
mysqlbinlog --start-datetime='2016-08-02 00:00:00' --stop-datetime='2016-08-03 23:01:01' -d hadoop /data/mysql/data/mysql-bin.000001 is
based on the pos value, note: hadoop is the library name, /var/lib/mysql/mysql-bin.000001 is the binary file path
mysqlbinlog --start-position=2098 --stop -position=2205 -d hadoop /data/mysql/data/mysql-bin.000001
