CentOS下

yum install -y sysstat
    
    systemctl start sysstat
    systemctl enable sysstat

Ubuntu下

#安装
    sudo apt-get install -y sysstat
    
    #修改配置文件
    sudo vi /etc/default/sysstat
    修改

    sudo vi /etc/cron.d/sysstat
    修改
    5-55/10 * * * * root command -v debian-sa1 > /dev/null && debian-sa1 1 1
    为
    */2 * * * * root command -v debian-sa1 > /dev/null && debian-sa1 1 1
    
    #重启服务
    sudo service sysstat restart
    
    sar -A
