安装Systemtap

Ubuntu

添加Ubuntu ddebs源文件，在命令行粘贴如下命令：


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

其中在Ubuntu 11.10中把universe，multiverse删除，改为：


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