Installer Sysbench

1. Installez Sysbench sur l'instance ECS.

   # Install the dependency library of Sysbench.
   yum -y install make automake libtool pkgconfig libaio-devel
   yum -y install mariadb-devel openssl-devel
   
   # Download the source code of Sysbench.
   wget "https://codeload.github.com/akopytov/sysbench/zip/refs/tags/1.0.20" -O sysbench-1.0.20.zip
   
   # Install the Unzip utility.
   yum -y install unzip
   
   # Decompress the source code.
   unzip sysbench-1.0.20.zip
   
   # Compile the source code.
   cd sysbench-1.0.20
   ./autogen.sh
   ./configure
   sed -i 's/MYSQL_OPT_COMPRESSION_ALGORITHMS/MYSQL_OPT_COMPRESS/g' ./src/drivers/mysql/drv_mysql.c
   make -j
   
   # Install Sysbench.
   make install

2. Préparez les scripts Lua : dm_large_table_write_only.lua (écritures sur tables volumineuses), dm_hot_update_only.lua (mises à jour de données fréquemment accédées) et dm_ddl_only.lua (synchronisation DDL).
