yum更新后"/usr/bin/yum", line 29, in ?的解决办法

yum的更新方法，可以到网上搜一下，这里不再累述。

我的yum更新后，出现的问题如下所示：

 

 

[root@sunss-22 yum.repos.d]# yum search php
================================================================== Matched: php ===================================================================
php-pear.noarch : PHP Extension and Application Repository framework
compat-readline43.i386 : edline 4.3

                                    compat-readline43.x86_64 : edline 4.3

                                                                          fonts-arabic.noarch : gollem-h3.noarch : The Horde web-based File Manager.

    return base.search(extcmds)

试了各种办法：

1.yum clean all

2.修改/etc/yum.conf,

[root@sunss-22 yum.repos.d]# 
[root@sunss-22 yum.repos.d]# cat /etc/yum.conf
[main]
cachedir=/var/cache/yum
keepcache=0
debuglevel=2
logfile=/var/log/yum.log
distroverpkg=redhat-release
tolerant=1
exactarch=1
obsoletes=1
gpgcheck=1
plugins=1             #替换为plugins=0

# Note: yum-RHN-plugin doesn't honor this.
metadata_expire=1h

# Default.
# installonly_limit = 3

# PUT YOUR REPOS HERE OR IN separate files named file.repo
# in /etc/yum.repos.d

 

3.修改fastestmirror.conf

 

fastestmirror.conf
[root@sunss-22 pluginconf.d]# cat fastestmirror.conf 
[main]
enabled=1        #替换为enabled=0
verbose=0
socket_timeout=3
hostfilepath=/var/cache/yum/timedhosts.txt
maxhostfileage=10
maxthreads=15
#exclude=.gov, facebook
[root@sunss-22 pluginconf.d]# 

等等，一系列工作都不行，最后解决办法：

#yum clean all
#rm -f /var/lib/rpm/__db*
#rpm --rebuilddb
#yum update
