Fedora 8中使用axel加速yum

转亚森罗平大侠的贴子
1.自己编辑相关的repo文件，fedora.repo和fedora-updates.repo

改为不使用镜像列表，并添加镜像服务器，修改如下：
＃fedora.repo文件[code][fedora]

注意:这里的服务器可以自己定义,你可以只选择对自己来说最快的几个服务器即可

2.a.下载axel源码包并进行编译
到下面站点下载最新的axel源码包,http://wilmer.gaast.net/main.php/axel.html

.进入下载目录:
$tar zxvf 文件名
$cd 解压出来的目录
$./configure --i18n=1
$make
$make install

b.下载站点上有axel的rpm包提供,我没有试,有兴趣的帮忙试一下

3.我修改了服务器的地址,直接定位到rpm包所在的目录,因此无须进行判断,直接下载即可,如果使用的是镜像列表,则仍然需要进行i386和os的判断,具体请参见wq1977兄弟的帖子--关于yum太慢了的解决方案
我修改过的axelget,去掉了os,axelget.py文件代码:[code]from yum.plugins import PluginYumExit, TYPE_CORE, TYPE_INTERACTIVE
from urlparse import urljoin
import os

requires_api_version = '2.3'
plugin_type = (TYPE_CORE, TYPE_INTERACTIVE)

enablesize=300000
trymirrornum=-1
maxconn=10

def init_hook(conduit):
global enablesize,trymirrornum,maxconn
enablesize = conduit.confInt('main','enablesize',default=30000)
trymirrornum = conduit.confInt('main','trymirrornum',default=-1)
maxconn = conduit.confInt('main','maxconn',default=10)

def predownload_hook(conduit):
global enablesize
preffermirror=""
for po in (conduit.getDownloadPackages()):
if hasattr(po, 'pkgtype') and po.pkgtype == 'local':
continue
totsize = long(po.size)
ret = False
if totsize <= enablesize:
conduit.info(2, "Package %s download size %d less than %d,Skip plugin!" % (po.repo.id,totsize,enablesize))
continue
else:
conduit.info(2, "Ok,we will try to use axel to download this big file:%d" % totsize)
local = po.localPkg()
if os.path.exists(local):
if not os.path.exists(local+".st"):
fstate=os.stat(local)
if totsize == fstate.st_size:
conduit.info(2,"Target already exists,skip to next file!")
continue
localall = "%s %s" % (local,local+".st")
rmcmd = "rm -f %s" % (localall)
curmirroridx = 0
conduit.info(2,"Before we start,clean all the key files")
os.system(rmcmd)
connnum = totsize / enablesize
if connnum > maxconn:
connnum = maxconn
mirrors=[]
mirrors[:0]=po.repo.urls
if preffermirror != "":
mirrors[:0] = [preffermirror]
for url in mirrors:
curmirroridx += 1
if (curmirroridx > trymirrornum) and (trymirrornum != -1):
conduit.info(2, "Package %s has tried %d mirrors,Skip plugin!" % (po.repo.id,trymirrornum))
break
remoteurl = urljoin(url, "%s" % po.remote_path)
syscmd = "axel -a -n %s %s -o %s" % (connnum,remoteurl,local)
conduit.info(2, "Execute axel cmd:\n%s" % syscmd)
os.system(syscmd)
if os.path.exists(local+".st"):
conduit.info(2,"axel exit by exception,let's try another mirror")
continue
else:
ret = True
preffermirror=url
break
if not ret:
conduit.info (2,"try to run rm cmd:%s" % rmcmd)
os.system(rmcmd)[/code]axelget.conf文件代码:[code][main]
enabled=1
enablesize=10000
trymirrornum=3[/code]新建这两个文件,将文件axelget.conf放入/etc/yum/pluginconf.d/目录，将axelget.py放入/usr/lib/yum-plugins/即可

然后:
sudo yum clean all
sudo yum update

4.注意事项:
1.如果出现错误找不到axel命令,编辑~/.bash_profile ,将PATH改为如下所示:
PATH=$PATH:$HOME/bin:/usr/local/bin:/usr/local/sbin:/bin:/sbin:/usr/bin:/usr/sbin

2.可在http://mirrors.fedoraproject.org/publiclist/Fedora/$releasever/$basearch/查询可用的服务器，可能是因为Fedora 8 刚刚发布，所以有部分服务器还没有开放updates，如果提示没有这个目录，建议换个服务器或者是等待一段时间再试

3.baseurl的第一个服务器是绝对可以用的,是稳妥的设置,但速度上比较一般,50-100KB/s的样子可以根据自己实际情况更改为更快的服务器。
