  • Linux利器之perf(火焰图)

    1 Ubuntu下安装perf

    在Ubuntu18上默认没有安装perf,可以通过如下命令尝试:sudo apt-get install linux-tools

    结果出来以下内容:

    E: Package 'linux-tools' has no installation candidate

     一般选择安装 linux-tools-generic 就好了,使用如下命令:

    sudo apt-get install linux-tools-common 
    sudo apt-get install linux-tools

    可能提示错误,这个时候按照提示升级安装即可:

      You may need to install the following packages for this specific kernel:
