[Centos7]bbc tools安装

更新到最新 CentOS 7.3 1611

yum update -y

cat /etc/redhat-release

CentOS Linux release 7.3.1611 (Core)

 

安装elrepo内核

rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org

rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm

然后先 rpm -qa |grep kernel

先卸载旧的 kernel-headers，kernel-tools, kernel-tools-libs，只保留内核，

然后 yum --enablerepo=elrepo-kernel install kernel-ml

就会安装elrepo正式版4.9内核，跟着再安装kernel-ml-headers kernel-ml-tools kernel-ml-tools-libs

yum --enablerepo=elrepo-kernel install  kernel-ml-headers kernel-ml-tools kernel-ml-tools-libs

然后

grub2-mkconfig  -o /boot/grub2/grub.cfg

生成启动菜单,把kernel-ml 4.9设为默认，参考下面技巧，然后重启

# awk -F\' '$1=="menuentry " {print i++ " : " $2}' /etc/grub2.cfg

安装sysdig

curl -s https://s3.amazonaws.com/download.draios.com/stable/install-sysdig | sudo bash

 

安装bcc-tools

yum install -y bison ethtool flex git iperf libstdc++-static \

python-netaddr python-pip gcc gcc-c++ make zlib-devel \

elfutils-libelf-devel

yum install -y luajit luajit-devel  # for Lua support

yum install -y http://dl.marmotte.net/rpms/redhat/el7/x86_64/netperf-2.6.0-1.el7/netperf-2.6.0-1.el7.x86_64.rpm

pip install pyroute2

 

安装依赖包：

cd /root

yum install -y git gcc gcc-c++

 

安装cmake3.7

wget https://cmake.org/files/v3.7/cmake-3.7.1.tar.gz

tar -xf cmake-3.7.1.tar.gz

cd cmake-3.7.1

./bootstrap

gmake 

make install

echo 'export PATH=$PATH:/usr/local/bin' >> ~/.bashrc

source ~/.bashrc

 

安装llvm3.9

cd /root

wget http://releases.llvm.org/3.9.1/llvm-3.9.1.src.tar.xz

tar -xf llvm-3.9.1.src.tar.xz

wget http://releases.llvm.org/3.9.1/cfe-3.9.1.src.tar.xz

tar -xf cfe-3.9.1.src.tar.xz

mv cfe-3.9.1.src llvm-3.9.1.src/tools/

mkdir llvm-build

cd llvm-build

cmake -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX=/usr/local -DLLVM_TARGETS_TO_BUILD="BPF;X86" -DCMAKE_BUILD_TYPE=Release ../llvm-3.9.1.src

make

make install

编译的时间稍微有点儿长。

 

安装bcc-tools

cd /root

git clone https://github.com/iovisor/bcc.git

mkdir bcc-build

cd bcc-build

cmake -DCMAKE_INSTALL_PREFIX=/usr ../bcc

make

make install

编译也不快，因为我用的虚拟机吧。

安装完成时候就可以到 /usr/share/bcc/tools 目下体验bbc-tools的强大了。
