Enabling Gazelle in MySQL

Start the MySQL server.

       
            LD_PRELOAD=/usr/lib64/liblstack.so GAZELLE_BIND_PROCNAME=mysqld /usr/local/mysql/bin/mysqld --defaults-file=/etc/my.cnf --bind-address=192.168.200.8 &

Modify the following parameters as required:

/usr/local/mysql/bin/mysqld: MySQL installation path
/etc/my.cnf: path to the MySQL configuration file
192.168.200.8: allocated service IP address

MySQL is started successfully if information similar to the following is displayed:

Verify that Gazelle has been successfully configured. If the service network is connected, Gazelle is enabled successfully. Run the following command on the client server to log in to the MySQL client and check whether the service network is normal:

       
            /home/mysql-8.0.25/build_release/install/bin/mysql -uroot -p123456 -h192.168.200.8 -P3316

Modify the following parameters as required:

/home/mysql-8.0.25/build_release/install/bin/mysql: MySQL client installation path
192.168.200.8: allocated service IP address
3316: allocated service port number

If information similar to the following is displayed, the service network connectivity is normal.

Perform a TPC-C test to obtain the performance improvement data after the Gazelle network optimization feature is used. For details about the test, see BenchmarkSQL Test Guide.
The Gazelle network optimization feature improves the comprehensive TPC-C performance by 10%. Figure 1 shows the effect before and after the optimization.
