刚才把源的配置改了一下，使用教育网的镜像，安装了几个软件，如下：
编辑/etc/pacman.conf 添加服务器地址：
[current]
Server = http://mirror.bjtu.edu.cn/ArchLinux/current/os/i686
[extra]
Server = http://mirror.bjtu.edu.cn/ArchLinux/extra/os/i686
[testing]
Server = http://mirror.bjtu.edu.cn/ArchLinux/testing/os/i686
[community]
Server = http://mirror.bjtu.edu.cn/ArchLinux/community/os/i686
[unstable]
Server=http://mirror.bjtu.edu.cn/ArchLinux/unstable/os/i686

现在再换回原来的源，提示以下错误：
[root@myhost etc]# pacman -Sy pacman
config: line 74: all directives must belong to a section
config: line 74: all directives must belong to a section
config: line 74: all directives must belong to a section
:: Synchronizing package databases...
failed to synchronize current
failed to synchronize extra
failed to synchronize community

目前的pacman.conf:
[current]
# Add your preferred servers here, they will be used first
Include = /etc/pacman.d/current

[extra]
# Add your preferred servers here, they will be used first
Include = /etc/pacman.d/extra

[community]
# Add your preferred servers here, they will be used first
Include = /etc/pacman.d/community


/etc/pacman.d/current等文件：
第74行：
#Mirror chosen in setup
Server = ftp://mirror.pacific.net.au/linux/archlinux/current/os/i686
没有改，和以前一样。

到底什么原因，请高手指教，多谢！

已经解决了，解决办法：
手工修改/etc/pacman.conf文件，将Include=/etc/pacman.d/current等引用全部修改为服务器的地址，修改后的配置文件如下：
[root@myhost pacman.d]# cat /etc/pacman.conf
[current]
# Add your preferred servers here, they will be used first
#Include = /etc/pacman.d/current
Server = ftp://mirror.pacific.net.au/linux/archlinux/current/os/i686

[extra]
# Add your preferred servers here, they will be used first
#Include = /etc/pacman.d/extra
Server = ftp://mirror.pacific.net.au/linux/archlinux/extra/os/i686

[community]
# Add your preferred servers here, they will be used first
#Include = /etc/pacman.d/community
Server = ftp://mirror.pacific.net.au/linux/archlinux/community/os/i686

然后执行pacman -Sy pacman 即可解决了。

但为什么不能使用Include = /etc/pacman.d/community引用了？还没有想明白。
