Record of how to install Systemtap on Ubuntu/CentOS system image

Because we need to install Systemtap on the server for some operation and maintenance needs, in this article Snail records how to install Systemtap on the Ubuntu/CentOS system image. You can refer to it if we need it.

First, Ubuntu

Add the Ubuntu ddebs source file and paste the following command on the command line:

codename=$(lsb_release -c | awk \\\'{print $2}\\')sudo tee /etc/apt/sources.list.d/ddebs.list << EOFdeb http://ddebs.ubuntu .com/ ${codename} main restricted universe multiversedeb http://ddebs.ubuntu.com/ ${codename}-security main restricted universe multiversedeb http://ddebs.ubuntu.com/ ${codename}-updates main restricted universe multiversedeb http://ddebs.ubuntu.com/ ${codename}-proposed main restricted universe multiverseEOF

Among them, universe and multiverse are deleted in Ubuntu 11.10 and changed to:

codename=$(lsb_release -c | awk \\\'{print $2}\\')sudo tee /etc/apt/sources.list.d/ddebs.list << EOFdeb http://ddebs.ubuntu .com/ ${codename} main restricteddeb http://ddebs.ubuntu.com/ ${codename}-security main restricteddeb http://ddebs.ubuntu.com/ ${codename}-updates main restricteddeb http://ddebs .ubuntu.com/ ${codename}-proposed main restrictedEOF

Ubuntu Key certification:

sudo apt-key adv –keyserver keyserver.ubuntu.com –recv-keys ECDCAD72428D7C01

sudo apt-get update -y

Install Systemtap:

sudo apt-get install -y systemtap gcc

yum install systemtap kernel-devel
