一：卸载的时候出现的错误：

umount /dev/nb1

device is busy

解决：找到是什么进程使得他busy，用 lsof /dev/nb1 . kill掉那个进程,然后重新umount即可。

二：GD2编译的时候出现的错误：

The usual way to define `LIBTOOL’ is to add `AC_PROG_LIBTOOL’

Libtool library used but `LIBTOOL’ is undefined

[Makefile.in] Error 1

解决：缺少编译安装的软件包。如：yum install automake,libjpeg-devel,libpng-devel,freetype-devel,libtiff-devel,autoconf,gettext-devel,libtool

三：安装 snmp的时候出现的错误：

1>/bin/sed: can’t read /usr/lib/libbeecrypt.la: No such file or directory

libtool: link: `/usr/lib/libbeecrypt.la’ is not a valid libtool archive

make[1]: *** [libnetsnmpmibs.la] Error 1

解决：以为缺少libbeecrypt.la ，libbeecrypt.so等共享库，如：yum install libbeecrypt.la

2>/usr/bin/ld: cannot find -lelf

解决：ln -s /usr/lib/libelf.so.1 /usr/lib/libelf.so

3>/usr/bin/ld:can’t not find -lselinux

解决：缺少libselinux 和 libselinux-devel包，如：yum install libselinux

四：Rsync同步常见问题：

错误一：

@ERROR: auth failed on module xxxxx

rsync: connection unexpectedly closed (90 bytes read so far)

rsync error: error in rsync protocol data stream (code 12) at io.c(150)

解决：这是因为密码设置错了，无法登入成功，检查一下rsync.pwd，看客服是否匹配。还有服务器端没启动rsync 服务也会出现这种情况。

错误二：

password file must not be other-accessible

continuing without password file

Password:

解决：这是因为rsyncd.pwd rsyncd.sec的权限不对，应该设置为600。如：chmod 600 rsyncd.pwd

错误三：

@ERROR: chroot failed

rsync: connection unexpectedly closed (75 bytes read so far)

rsync error: error in rsync protocol data stream (code 12) at io.c(150)

解决：这是因为你在 rsync.conf 中设置的 path 路径不存在，要新建目录才能开启同步。

错误四：

rsync: failed to connect to 218.107.243.2: No route to host (113)

rsync error: error in socket IO (code 10) at clientserver.c(104) [receiver=2.6.9]

解决：对方没开机、防火墙阻挡、通过的网络上有防火墙阻挡，都有可能。关闭防火墙，其实就是把tcp udp 的873端口打开。

五：软件安装的时候常出现的问题：

configure: error: …No recognized SSL/TLS toolkit detected

# yum -y install openssl-devel

configure: error: no acceptable cc found in $PATH

yum -y install gcc-c++

configure: error: cannot find output from lex; giving up flex is not installed, install flex.

yum -y install flex

configure: error: xml2-config not found. Please check your libxml2 installation.

yum -y install libxml2-devel

configure: error: Cannot find OpenSSL’s

yum -y install openssl-devel

configure: error: Please reinstall the BZip2 distribution

yum -y install bzip2-devel

configure: error: Please reinstall the libcurl distribution - easy.h should be in /include/curl/

yum -y install curl-devel

configure: error: libjpeg.(a|so) not found.

yum -y install libjpeg-devel

configure: error: libpng.(a|so) not found.

yum -y install libpng-devel

configure: error: freetype2 not found!

yum -y install freetype-devel

configure: error: Unable to locate gmp.h

yum -y install gmp-devel

configure: error: Cannot find pspell

yum -y install aspell-devel

libtool: link: cannot find the library `/usr/lib/libbeecrypt.la’ (librpmio.la: /usr/lib/libbeecrypt.la)

解决：缺少beecrypt包，如：

http://sourceforge.net/projects/beecrypt下载beecrypt-4.1.2.tar.gz

然后运行如下命令：

#tar -zxvf beecrypt-4.1.2.tar.gz

#./configure

#make

#make install
