distcc

1. QUICKSTART
       1      For each machine, download distcc, unpack, and install.

       2      On each of the servers, run distccd --daemon with --allow options to restrict access.

       3      Put the names of the servers in your environment:
              $ export DISTCC_HOSTS='localhost red green blue'

       4      Build!

              $ make -j8 CC=distcc

2. USING DISTCC WITH CCACHE
       ccache  is  a program that speeds software builds by caching the results of compilations.  ccache is normally called before distcc, so
       that results are retrieved from a normal cache.  Some experimentation may be required for idiosyncratic makefiles to  make  everything
       work together.

       The most reliable method is to set

              CCACHE_PREFIX="distcc"

       This  tells  ccache  to  run  distcc  as  a  wrapper around the real compiler.  ccache still uses the real compiler to detect compiler
       upgrades.

       ccache  can then be run using either a masquerade directory or by setting

              CC="ccache gcc"

       As of version 2.2, ccache does not cache compilation from preprocessed source and so will never get a cache hit  if  it  is  run  from
       distccd or distcc.  It must be run only on the client side and before distcc to be any use.

       distcc's pump mode is not compatible with ccache.

3. 设置：

# 除了正在使用的 gcc 的版本，机器上通常不需要其他任何公用的东西
# 告诉 distcc 它可以使用哪些机器
vi /etc/distcc/hosts
localhost/3 192.168.23.38/3

export DISTCC_HOSTS="localhost 192.168.23.38"
或者export DISTCC_HOSTS="localhost 192.168.23.13"

# avoid blocked
distccd --daemon --allow 192.168.23.13 --allow 192.168.23.38

/etc/init.d/distccd start

make -j8 CC=distcc
