Using mysqlbinlog to View Binlogs

Scenarios

The mysqlbinlog tool is used to parse binlogs and is contained in the MySQL software package. You can download a MySQL software package of your desired version from the MySQL official website, decompress the package, and obtain the mysqlbinlog tool from the decompressed package (mysqlbinlog 3.4 is for MySQL 5.6 and 5.7). If your mysqlbinlog version is too old to correctly parse binlogs, perform the operations described in this section.

You can also use a third-party tool to parse binlogs for RDS for MySQL.

Procedure

1. Download a MySQL software package.
   

   It is recommended that the software package version be the same as your current MySQL major version.

   If your MySQL version is 5.7.27, download the following software packages:

   • Product Version: 5.7.27
   • Operating System: Linux-Generic

   The downloaded MySQL software package is mysql-5.7.27-linux-glibc2.12-x86_64.tar.gz.

   Figure 1 Download
   

2. Decompress the software package and find the mysqlbinlog tool.
3. Find the mysqlbinlog tool version.

   [root@ecs]# tar -zxf mysql-5.7.27-linux-glibc2.12-x86_64.tar.gz
   [root@ecs]# cd mysql-5.7.27-linux-glibc2.12-x86_64/bin
   [root@ecs]# ll mysqlbinlog
   -rwxr-xr-x 1 7161 31415 11310886 Jun 10 2019 mysqlbinlog
   [root@ecs]# ./mysqlbinlog -V
   ./mysqlbinlog Ver 3.4 for linux-glibc2.12 at x86_64

4. Use mysqlbinlog to parse binlogs.
   The following uses mysql-bin.000001 as an example:

   [root@ecs]# ./mysqlbinlog --no-defaults -vv /root/mysql-bin.000001
