环境：Linux  
以下几个工具都是基于FlameGraph ([http://www.brendangregg.com/flamegraphs.html][http_www.brendangregg.com_flamegraphs.html])来展开的。

## 首先安装python-flamegraph ##

[https://github.com/evanhempel/python-flamegraph][https_github.com_evanhempel_python-flamegraph]

pip/ pip3 install git+https://github.com/evanhempel/python-flamegraph.git
    cd pyflame
    ./autogen.sh
    ./configure
    此时运行make命令会出现提示：
    Making all in src
    make[1]: Entering directory `/root/pyflame/src' make all-am make[2]: Entering directory `/root/pyflame/src' make[2]: Leaving directory `/root/pyflame/src' make[1]: Leaving directory `/root/pyflame/src'
    make[1]: Entering directory `/root/pyflame' make[1]: Nothing to be done for `all-am'. make[1]: Leaving directory `/root/pyflame' 不用管它。 继续运行： make check 会提示以下 Making check in src make[1]: Entering directory `/root/pyflame/src'
    make[1]: Leaving directory `/root/pyflame/src' make[1]: Entering directory `/root/pyflame' make[1]: Nothing to be done for `check-am'. make[1]: Leaving directory `/root/pyflame'
    ./runtests.sh -v
    make: *** [check] Error 1
    继续不用管
    运行 make install
    提示：
    Making install in src
    make[1]: Entering directory `/root/pyflame/src' make[2]: Entering directory `/root/pyflame/src' /usr/bin/mkdir -p '/usr/local/bin'
      /bin/sh ../libtool   --mode=install /usr/bin/install -c pyflame '/usr/local/bin'
    libtool: install: /usr/bin/install -c pyflame /usr/local/bin/pyflame
    make[2]: Nothing to be done for `install-data-am'. make[2]: Leaving directory `/root/pyflame/src' make[1]: Leaving directory `/root/pyflame/src' make[1]: Entering directory `/root/pyflame'
    make[2]: Entering directory `/root/pyflame' make[2]: Nothing to be done for `install-exec-am'. /usr/bin/mkdir -p '/usr/local/share/man/man1'
     /usr/bin/install -c -m 644 'docs/pyflame.man' '/usr/local/share/man/man1/pyflame.1'
    make[2]: Leaving directory `/root/pyflame' make[1]: Leaving directory `/root/pyflame' 此时要注意了： 此时运行提示里的： /usr/bin/mkdir -p '/usr/local/bin' /usr/bin/install -c pyflame /usr/local/bin/pyflame 即可安装成功 运行以下命令如果有输出即安装成功 pyflame -t python -c 'print(sum(i for i in range(100000)))'
    4999950000

## 接下来安装FlameGraph ##

wget https://github.com/brendangregg/FlameGraph/archive/master.zip
    unzip master.zip
    mv FlameGraph-master/ /opt/FlameGraph
    export PATH=$PATH:/opt/FlameGraph
    cd /opt/FlameGraph
    cp flamegraph.pl /usr/local/bin
    flamegraph.pl -h
    如果有以下输出，则安装成功
    Option h is ambiguous (hash, height, help)
    USAGE: /usr/local/bin/flamegraph.pl [options] infile > outfile.svg
    
    	--title TEXT     # change title text
    	--subtitle TEXT  # second level title (optional)
    	--width NUM      # width of image (default 1200)
    	--height NUM     # height of each frame (default 16)
    	--minwidth NUM   # omit smaller functions (default 0.1 pixels)
    	--fonttype FONT  # font type (default "Verdana")
    	--fontsize NUM   # font size (default 12)
    	--countname TEXT # count type label (default "samples")
    	--nametype TEXT  # name type label (default "Function:")
    	--colors PALETTE # set color palette. choices are: hot (default), mem,
    	                 # io, wakeup, chain, java, js, perl, red, green, blue,
    	                 # aqua, yellow, purple, orange
    ....
